The Four Fundamental Forces Of Physics Explained
Vložit

- Theoretical physics is very complicated, and there is still a lot we don't know about how the universe works. Trace and Julian are here to discuss the four fundamental forces of physics, and why we're still unsure about a lot of things.

Gravity is the strongest force... in the morning...
...and after lunch...
@Agnaye Ochani S/He means they can't get out of bed easily XD
@Agnaye Ochani omfg you killed me
@Agnaye Ochani oh God 😂
haha nice one XD
"Larger the object, the more gravity." You misspoke sir. It should be "More massive the object, the more gravity."
largeness correlates with massiveness :/ assuming uniform density
“Assuming”
But u know what he means lol
Lol Bro remeber things like black holes and neutron star. Theyre massive, have enormous density but are tiny in size
Johan Kjær Some black holes are not tiny and they are lightyears big
I really like the new guy, he's a good presenter and the right amount of nerdy.
I agree, he Annunciates his words far better than trace or tara (though they are still good at it as well) and keeps his speech flowing, making it easy to listen to him.
which one was new
he's on the left. Though.
STOP saying physics is hard!! You're speaking to a very large audience, plenty of whom are young and impressionable kids! So if we keep saying physics and math is too hard and if you study it you're not normal, we are likely to shy-away potential future leaders in STEM fields!!
+Kevin O'Sullivan ikr? I hate when people say "math is boring" or "math is hard" or even "math is useless" of course math is hard, boring, and useless if you dont understand how it works, and why we need it.
It is hard. That's part of the fun. If you think u can come up with a reason as to why electrons can change from particles to waves with logic there's a nobel prize waiting for you mr. knowitall. Why do you think its taken us 100s of years of extraordinary people to come up with formulas and ideas that give us the world today. Of course its hard, the Universe is NOT EASY. Both you and Apollyon just have a case of enjoying being offended. Pipe down :D
I love science and not to brag I am good at it. Physics is hard but very interesting.
r/iamverysmart
but it is hard. all stem degrees are. there is nothing good coming from telling people otherwise. if kids really want to be engineers or in general stem graduates they need to have a passion for it. whatever is worth it in life never comes easy.
I am no scientist but I've been fascinated by gravity since I had understanding of it and knowing there are still a lot of questions unanswered on the matter can only feed my curiosity. So much to learn and discover. So exciting!
I thought the 4 Fundamental Forces from strongest to weakest would be the following instead of as stated starting at 1:12…
- Strong Force
- Electromagnetic Force
- Weak Force
- Gravatational Force
en.wikipedia.org/wiki/Fundamental_interaction#Overview_of_the_fundamental_interactions
this is accurate
I'd really love to see a video explaining, in detail, much about the fundamental forces and the particles that control/inflence/get influenced by these forces
The electromagnetic force is stronger than the weak force , search it up
Gamer's Depot yes indeed
Yeah, I doubt it, so I find comments, then I found ya.
top-bottom shows the weak force varies in strength
and gravities weaker on an atomic level than the weak force but stronger at a larger level
Not true Einstein
The manliness in this video is palpable . . .
things I learned from this video:
- the fundemental forces
- what palpable means
May the forces of the universe be with you all... Oh wait they already are.
Brew simply mentioned Higgs Bosons in a video, and I didn't know what those were, and now I have gone on a very intriguing hunt for answers about basic particle physics on CZcams, leading me here. Thanks.
Well.. The relative strength of the electromagnetic force is 10^36 and relative strength of the weak nuclear force is 10^25. In other words the electromagnetic force is stronger than the weak nuclear force...
Fuck... the Subaru advert is back again...
Force (physics) does not exist physically in the same way that an object with mass, thus making it “not” the initial cause of pushing, pulling, shaping objects, motion, work or being a Vector Quantity (Magnitude + Direction).
In physics, the word, “Force” as we know it, turns out to be nothing more than an expression to express an idea, like one would use the word “Love” to express one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could enable the initial cause of motion making it counterintuitive.
Example: Without applying the Energy from within you, choose an object of your choices to push and pull by simply applying “only” the Force or Net Force.
Meaning that Energy (applied energy) is the origin of motion and not “Force”. Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (object in motion) comes in contact with another object(s), it makes a surface contact that will enable you to push and pull. Example: Ep=ma, Ep=mv and so on. Note: Ep is not to be confused as Kinetic Energy in any way.
Momentum represents things like work, wave, gravity, light, lightning, tsunami, earthquake, current, electricity, motion, magnetism, etc.
Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or “Ep” is the one and only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert and non-existence.
Energy is energy, but it’s when Energy (E) is being applied that creates the Momentum (p) making it the initial cause of motion. Example: Ep.
By applying the right amount of Energy, nothing is immovable or unstoppable. ~ Guadalupe Guerra
How does whether you are reading something from a book or a screen effect how you process the information. Also do people absorb information better from reading or audio books?
People absorb information by processing it through reflection or discussion. How the information is presented isn't relevant(though you would probably have a preference as to what you like best. Enjoyment/interest makes your brain more eager to learn).
Other than that, if you repeat it enough you can force your brain to accept it, whether or not you actually reflect on it.
I'd personally say reading is better, since you can read things over easily if you missed something. So I guess reading is easier on the short-term memory.
Even though i am a commerce student i love insanely science and to know about science DNews is the best channel probably in youtube.
(2:34) ". . . though, not for long." - Julian suddenly collapses into a heap on the floor and Trace just stares with confusion and awe -
The Electromagnetic force is stronger that the Weak force!
Trace, you said, "the larger the object, the more gravity". You probably meant, "the more massive the object, the more gravity". Probably just a slip up, though.
Or rather, "the more massive the object, the stronger its gravitational pull is on other objects (matter and even light)".
Shut the fuck up you fucking pedant
Steven Masso They also said that the weak force was stronger than the electromagnetic force =(
I've always thought of gravity like resistance in electrical engineering. You don't measure resistance directly but calculate with ohms law. V over I = R. The current flows from negative to positive as does time (not a law or even correct, just the way I think about it). So current is the flow of time, resistance is gravity, voltage would be mass (maybe, it's difficult to compare) and movement would be ampage. If this was the case I don't think we would be able to find a graviton since it be a result of the other forces. Take my thoughts with a pinch of salt, quantum mechanics us too damn confusing, but I feel the universe makes better sense to me when comparing to ohms law
I ship it
Sameeeeeee
I was just wondering, When people talk about the 4 fundamental forces in the universe, are these meant to be responsible for all the other forces in the universe? I would think so, but there are some forces, such as centripetal force, which i can't see being a result of the 4 fundamental forces of nature. Ultimately, what I'm trying to say is, are the known fundamental forces of nature responsible for EVERY force in the universe?
I have a question: For my homework i need to explain the ginzburg-london appproximation, do it for me pls
Do your own homework lol
fuck'n science that's how
The answer is "the Internet". As in Google it! As always.
You're asking for homework help in a youtube video comments section? I thought id seen every lazy way to do HW but you have shown me another. :(
i didn't think i'll get this many replys...if you noticed at the end of the Dnews video they asked "if you have any questions on physics put them down below", and i did...as a joke...
Just to inform people, it is completely not proven that gravitons are the particles, in fact almost disproven because it does not work with the mathematics. One of the main reasons people still theorize about string theory, is that, if the eleven dimensions could work, gravity could be explained, not by a particle, but by a property of all other particles. Gravitons are still just a theory. Although, all of it is just a theory, gravitons are a less likely theory than the other particles.
You know I've been driving a Subaru way before it was cool I don't I just ...like how it feels
We know, you watched South Park, whoopdee doo
DeadlyWhovian don't have to be such a negative Nancy
zev piro Subaru Forester Makes People think wtf when you hit the pedal to the metal.
I spent a good deal of that video thinking how I wanted the shirt Trace is wearing.
Question.
Do fundamental forces operate like gravity does? That is to say, do they possibly bend other dimensions to dictate how particle interact? Like how string theory says that particles are just an effect of wave patterns in smaller physical dimensions. Could charge and nuclear forces bend a dimension unseen? And could that bend dictate how particles move? What dimensions are we not focused on that dictates everything?
Truly. This channel is wonderful. I'm so glad to be a subscriber :)
It sounds so complicated. Some times I feel that we got it wrong from the start and going further will get more complicated
Is gravity an infinite energy source? In the sense that an object's gravity will never "run out" over time? If that is the case, then I wonder why.
Joey Young as long as the object moves along 4d timeline he will warp spacial dimension therefore creating gravity.
Question why can't we create the same effect as gravity with electromagnetic force on space time.since electromagnetic force is much stronger than gravity another word can electromagnetic force create bend space time .
Love your t-shirt:)
Thanks and nice t-shirt 👕 Trace 🙆.
Which of the four forces binds the proton nucleus with the orbiting electrons?
can you guys explain the double slit experiment, and what does consciousness have to do with it ????
make it five folks
I like Julian, hope he does more episodes.
Trace and Julian make an awesome pair.
I am 15 and I've already made a theory about black holes.
At the end of a star's life due to the immense force of the supernova the space-time barrier breaks, the supernova has to have enough energy to do this, that is why only the larger stars have a supernova big enough to do this. When you enter a black hole, time stops, this is because you have left space and time itself, you have went past the barrier.
The other side of the space time barrier is probably empty and the visible universe is full of matter and energy, maybe instead of gravity pulling things in it is the natural process of osmosis making the matter and energy leak from our very high pressure universe to the empty area outside space-time with such frivolity because of the massive difference between the pressure of the two areas that it replicates the immense force of our current theory about black holes.
I think you meant you've already read about black holes on Wikipedia.
isn't the weak force weaker then electromagnetism??
Forces in physics are of these four types, and various phenomena which involves physics happen with these forces.
Elegant explanation because it really simplified a rather complicated question... just super fast... replay... replay... ☺️
What force is i am using to connect my computer through RJ-45 cable connector, to another computer? -Gravity? and what if the connector pins break down, is that the blackhole level of gravity? thanks.
I was a little skeptical coming in and I was correct. You can't explain the four fundamental forces of physics in under 4 minutes. You just had enough time to name them, tell us what they did, and where they come from, but not really explain them.
well this is more of a summary, so id expect that
I love Trace's t-shirt. :'D
What is it about blackholes and entropy principle in the second law of thermodynamics?
Why does the weak force attack the protons less than the neutrons? Is spin down like decelleration maybe?
"The Forces Of Physics" sounds like it's a superhero show
How long does it take for gravity and electromagnetism to be noticed?
Sir, I have a doubt, there is this gravitational force acting towards the centre of the earth., which produces an acceleration of 9.8 m/s^2 on the body which is coming towards it. So why isn't Earths collapsing into itself, is it because that the force is not enough to do it or is there any reason.
the earth is going 1000 mph including everything on it .such as humans.
F = ma
if there's gravity waves (spacetime ripples) than they're comparable to sound waves, right? so then would a "gravition be like a cavitation bubble (like underwater)??
can gravity be that electrons in the atoms of our body be attracted to the huge amount of protons in the atoms of earth? could it be the difference in charge? electrostatic force?
Physics (F=ma) test: “Without” applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.
Wait for the 5th force. It will revolutionize the way we explain the universe.
I was taught that electromagnetism is stronger than the weak interaction.
I believe there are 2 forces and any other forces merely propagated from these forces through time(or shall I say - the accumulative vibrations in space).
The universe follows a rule of balance. In order to have a balance there has to be a counterpart for any given. Who is the mother and father of our Universe though? I don't know - nobody does yet. Language does make thinking about this confusing because we define things definitively - where nothing is actually definitive. Things are merely perspectives based on the point you are at, whilst observing the vibrations. The more vibrations and reactions that happen (ie. the more we go through time) the more intricate things seem to be. For Earth surviving in the Goldilocks zone experiencing an unbelievable amount of vibrations through the air; for life to be the way it is, is so intricate.
One line - one line rules all theories in my book: "Energy will take all possible paths, but will always prefer the path of least resistance" Why? - I'd really love to know.
Look at life. We have been engineered by nature to survive.
Why? Well, energy will take the path of least resistance and if you see the path of evolution, extinctions etc etc, the path of most resistance will be to die under any natural circumstance hence we fight to survive.
Someone offers you $1 mil. You would think this is a scam sure, but if it were true with no strings - anybody would take it. Energy knows it makes survival easier; and what makes survival easy is a path of little resistance.
But a suicide victim? Those poor people are in a state where energy doesn't know what path to take. All paths lead to resistance except one. One at which ends the resistance that lies within, that is death.
Habits: the longer a habit is kept the harder it is to break. The path has been made and practiced. to undo the path you must focus the energy to a less resistant path.
The universe is an unfathomable thing... Keep exploring!
Oh my, thank goat for the old intro back! :D
umm... can somebody here please explain in a simple way and give a very simple example of the 'weak force' please? To some small extent I can understand the other three forces but never the weak force, its just so confusing to me. I didn't understand what they say in the video concerning the weak force, so please someone reply.
Electromagnetism is considerably stronger than the weak force.
Make more videos about science and less about science news. I want to learn something from the videos I watch. Make more videos about science like this one, explaining things science already knows to your viewers. Not explaining new discoveries
What is the name of their channel hmm? DNews? Now, why do you a channel by the name of DNews would have more videos about science news that not?
Yah seriously... Their called DNews... As in Discovery News...
I'll just direct you to a channel called scishow. They cover a lot more stuff directly science-related, especially scishow space, their secondary channel.
I'm just subscribed to both scishow and dnews. Scishow is a bit more interesting and delves a bit deeper into the science behind stuff compared to dnews, which focuses more on analogies and statistics.
D'NEWS'
Thanks Edward, we love doing science videos too, we try and mix it up with some news and some educational stuff. If you REALLY want to get into science SciShow is great, and so is Henry Reich's Minute Physics!
Excellent.. thank you both :-)
posted 30 seconds ago with 0 views!!! im early
Could you please tell me ...where do the laws of nature come from?
Fast, Smart, Geeky Cool & Wildly Messy Fun! Great summary and shirts lol :P
break down at the "atomic" level? is that correct?
I’m wondering if there’s a fundamental force that doesn’t have to exchange, where as most we know to do? What if a force can push through not necessarily unnoticed, but that’s what that force requires to do it’s job? If so you wouldn’t see it acting against any force as this would be able to manoeuvre like fluid (say like an invisible stream, you’d see acting against the rocks but you wouldn’t see the water unless you knew what you was looking for)
Is time a force? it's something that we are constantly being pushed forward in (or pulled forward into)...
Sir i want to ask you a question personaly plz..
u guys r great... and thank a lot...
can u please make a video describing quantum numbers..
like where did they came from and why?
how an particle hae half spin?
not much in deep... just why and how?
please please please
Hi guys appreciate it n ma question is y gravitational force is the weakest?
I would like to know what makes up the subatomic particles what makes up those and so on and so on
Can you make a video on quatum field theory in physics im still trying to grasp my head around it?
"Minute Physics" Help!!!
Trace's shirt is so cute! Yes, off topic I know.
what if u have 2 magnets that repel and 1 magnet that attracts both the magnets together what would happen
Me at the end of these videos always: "Well, those words were fun!"
Trace, your shirt is so cool man , stole the show!'
Did you even mention the Standard Model? The difference between quarks leptons (quarks have color charge)? Did you even mention the force carriers, the eight gluons and how they exchange colors between quarks, or the W+, W-, and Z bosons and how they change flavors of quarks and leptons? Did you even mention how exchange of mesons like pions between baryons holds them together in atomic nuclei? I don't think you even mentioned that protons are up+up+down and neutrons are up+down+down; nor did you mention that the weak decay of the temporary delta++ (up+up+up) and delta- (down+down+down) states back into protons or neutrons is what creates the positive/negative pion. Deuterium is kept together by this "residual strong force," the exchange of pions. It's not the strong force, even though the mesons themselves, as quark-antiquark pairs, are held together by the exchange of gluons (g3 and g8) just like how baryons (triplets of quarks) are held together by exchange of a different set of gluons (g1, g4, g6 swap colors, g2, g5, g7 offer a multi-step way to rotate quarks into antiquarks and form mesons). Meson exchange is a force in its own right, since mesons are bosons (they have integer spin). The symmetry is broken by the masses of the quarks, and the mesons have mass and therefore have short range, as a force that decays exponentially with distance. Did you even mention the Higgs field and Higgs boson, and how it breaks the symmetry of the weak force and makes the W+, W- (80.4 GeV) and Z (91.2 GeV) massive, which in turn makes the weak force weak and gives different masses to each of the quarks and leptons? And did you even mention that there exist three generations of spin 1/2 matter? And recent developments proving that the second generation can be spin 1/2 or 3/2, and the impending announcements that third generation particles can be spin 1/2, 3/2 or 5/2? Did you even talk about spin, the spin-statistics theorem, and how particles with integer spin are force carriers while particles with half-integer spin obey the Pauli exclusion principle and take up space? Did you even mention how exchange of the massive Z boson is the fundamental force that prevents two fermions from being in the same place at the same time?
I've always wondered, and hopefully someone can enlighten me; if there's no up or down in space, in which direction do objects "bend" the space/time mesh? Looking at models of, say, the earth warping space around it so that the moon orbits around it, how is it determined that the earth is warping in the direction of the South Pole?
the earth is bending space in a spherical shape that is extremely difficult to draw or represent on a flat surface like your monitor.
+Wayne Shaw thank you!!!
Ricardo Franco To draw a representation of the curvature of a 3D space, you'd need a 4D space as canvas.
Thanks for the video, DNews! I have a theoretical "what if" question: theoretically, what would happen if a human sperm for some reason had all of its genetic material removed - poof! - while it was on its way to fertilize a human egg? If the sperm reached the egg first, would the egg accept it? Would it then block all newcomers, like is normally done, right? Would it ever recognize that the sperm lacked genes? I apologize that my question is complicated by epigenetics!
If you must know, this idea popped into my head when I was thinking of potential more-effective, less-invasive contraceptives. I myself am a virgin, but I recently saw CZcams channel TheBibleReloaded's review of the film "God Loves Uganda," and in it was discussed the G. W. Bush administration's aversion to condoms being sponsored as a contraceptive in Uganda in order to halt the AIDS problem there, instead favoring a policy of abstinence education, I suppose because promoting condoms would be tantamount to condoning fornication to the Christian community. I myself am an Abrahamic misotheist, and while I do not feel morally prohibited from promoting and sponsoring preventative sex ed, I still believe that abstinence is indeed superior to preventative measures, both medically and "spiritually," if you will, or as I would say, mentally and emotionally; much cleaner and better in the long run, in my opinion! Anyway, despite all that, I was thinking that condoms must not be very fun to use, despite having never been in contact with one! So I was thinking about potential alternative contraceptives. Then I though, "Wait, doesn't the egg 'seal up' or something once it has been fertilized? What if an 'empty' sperm could be cultivated which the woman could 'fertilize' her body with prior to intercourse?" Zany, I know, and probably not cost-effective, certainly compared to condoms, but persons don't always use condoms, and since my idea is a biological approach, perhaps it may have potential to have a higher effectiveness rate than condoms??? All the best!
The reason why condoms are so popular is that they protect against both sexually transmitted disease and also pregnancy. Even removing the genetic material from sperm, if that were somehow possible, would still leave you vulnerable to STDs. A combination of contraceptive methods is the best way to avoid pregnancy.
Condoms offer serious protection from STDs?
John Doe 878393719 yes
Could Dark energy be a fundamental force in which case there would be 5 not 4
Can u explain about God Particles
Some one say god partical give mass to the atom if we some how release the god partical to the object what will happens
Isn't the order from strongest to weakest: strong, electromagnetic, weak, gravitational force ?!
Have you ever noticed that we can photograph photons no matter what their frequency, however we can't photograph the carrier of the magnetic field?
Have you ever noticed that photons all across the electromagnetic spectrum can push on things, because they have momentum but they never pull on anything?
Have you ever noticed that almost all the characteristics of photons in the electromagnetic spectrum do not apply to the carrier of the magnetic force?
Different colours of light carry slightly different properties and it is possible that as you continue through the elcto-magnetic spectrum that the light takes on drastic new properties like being able to pull on matter. You can ask minute physics if you are desperate for an answer :D
Since all our imaging devices require electricity to function perhaps they are unable to detect the magnetic forces...etc etc you see where im going im clearly not a physicist. Anything that does not use electricity would be quite ineffective at seeing such a force.
Anyway all this is pure speculation but I wanted to share my thoughts
Yes, at different frequencies photons have different properties like high frequency all have an immediate and obvious effect on flesh, for example Microwave, gamma, X-ray, etc.
Have you ever noticed that when the magnetic force pours through your body in an electromagnetic train, or an MRI, that it doesn't effect your body in any of the ways that photons do?
"Have you ever noticed that we can photograph photons no matter what their frequency" No we can't, a lot of frequencies are too low energy for us to photograph, and a lot are too high energy.
"however we can't photograph the carrier of the magnetic field?" the carrier of the magnetic field is the photon.
"Have you ever noticed that photons all across the electromagnetic spectrum can push on things, because they have mass and velocity" photons don't have mass.
"Have you ever noticed that almost all the characteristics of photons in the electromagnetic spectrum do not apply to the carrier of the magnetic force?" all of them do, by definition.
BlueCosmology photons have momentum (mass times Velocity) and they have energy (Mass times the speed of light squared). However, they theoretically have a resting mass of zero so we will say momentum. There are pictures of galaxies and stars that were imaged in Radio frequency (very slow) all the way to Gamma (very high) because we can image the whole electromagnetic spectrum (photograph does suggest the visible spectrum due to convention, however if you look at the etymology of the word it works fine in all frequencies) . So it would seem that while I'm sure you are a bright guy/girl the validity of my questions still stands. Please think of everything you know about the electromagnetic waves in space and then try and compare that to the area influenced my a magnet and see if you can draw any parallels it's very difficult. If there was an electromagnetic generator of a frequency that could penetrate your body and a receiver a few feet apart, would you walk between them? NO! All such frequencies can cook you or cause cellular damage and cancer. If there were two huge magnets drawing on each other but they were bolted down would you walk between them? sure! extremely high power magnetism can have minimal effects on animals because we have polarized molecules, but the field wouldn't hurt you at all. Why? Once again the electromagnetic waves and the force carrier of magnetism don't share many similar qualities.
GengoNoTabi "photons have momentum (mass times Velocity)"
That is not what momentum is. That is an approximation of what momentum is that is only valid for objects moving much slower than the speed of light. Clearly, light which moves at the speed of light, is the furthest from this approximation that is possible.
"they have energy (Mass times the speed of light squared). "
That is an approximation of what energy is that is only valid for objects moving much slower than the speed of light. Clearly, light which moves at the speed of light, is the furthest from this approximation that is possible.
"There are pictures of galaxies and stars that were imaged in Radio frequency (very slow) all the way to Gamma (very high) because we can image the whole electromagnetic spectrum "
And? That is not the whole spectrum. We can not measure photons with energies too low to compton scatter off high Z material, we can not properly measure photons with very high energies that can compton scatter thousands of times before being low enough energy to be absorbed.
"Please think of everything you know about the electromagnetic waves in space and then try and compare that to the area influenced my a magnet and see if you can draw any parallels it's very difficult."
It really isn't at all. By the very definition of electromagnetism, magnetism is contained within it.
"If there was an electromagnetic generator of a frequency that could penetrate your body and a receiver a few feet apart, would you walk between them? NO! "
...Yes. That is constantly happening to you all the time. A non negligible proportion of electromagnetic waves from the sun and cosmic sources and all electronics penetrate you all the time.
"All such frequencies can cook you or cause cellular damage and cancer."
No they can not. Most frequencies do not have enough energy to ionize any material (what is needed to cause cancer.)
"Why? Once again the electromagnetic waves and the force carrier of magnetism don't share many similar qualities. "
There isn't a force carrier of electromagnetic waves, there is a force carrier of electromagnetism (which is electromagnetic waves).
The force carrier of magnetism and electromagnetism is exactly the same thing.
wait if gravity is just the curving of spacetime how can a thing like a graviton exist? Can someone explain plz. Thanks
Why don't we consider mass is concentric property of energy or graviton what makes mass.
What is the circumstance of 3.174
Hey , it will great if you guys can make one for Force fields
I gotta laugh at these guys. Thinking they know "The Strong Force". They're to young. Someday they'll get married. Then they'll know.
Inenstine said Gravity is mass bending space or mass as an occupier of space Einstein didn't believe gravity was a force at all; he said it was a distortion in the shape of space-time, otherwise known as "the fourth dimension" Basic physics states that if there are no external forces at work, an object will always travel in the straightest possible line. Accordingly, without an external force, two objects travelling along parallel paths will always remain parallel. They will never meet. think of a rock in water the water will push on every part of the rock it the same with mass in space. The space is displace So space will push on ever part of the mass. pushing on any object close to the mass as well
The suspense on BICEP2 is killing me.
Well-done
I feel like we really need to look into these gravitons it just seems like gravity and electromagnetism are so close they could almost be the same thing
the electromagnetic force was somewhat misrepresented - there are many physics who claim that this is the only force in the universe, and the interatomic forces are just its derivative.
You forgot to mention that there are many more physicists for don't just claim that there are 4 fundamental forces but have done countless experiments with evidence to prove and back up their theories.
Don't follow that electric universe 'theory' nonsense, the only thing they've proven is that they are crackpots who don't understand anything.
There are only 3 forces
Gravity is part of electromagnetism
and there is a 3rd lens,
Not just mirror and glass lens, There is a Gas Lens thats been hidden and locked away and told Does work
Electromagnetism is the strongest force, the strong force only dominates at extremely small distance, this is why fusion is so hard to achieve.
Where does Trace get all these awesome shirts lol
Trace, Julian,I have a question!
So D*s3 (2860) is the exchange particle for strong NF - it is the gluon itself? It seems weird that the exchange particle is heavier that the objects that exchange it.
But anyway, surely then, because of it's mass, on mass spectrometry, for example, atoms would appear heavier than the proton+neureon number. Or is this gluon not detectable for spectroscopy?
I know you didn't ask me but I'm pretty sure these gentleman have no idea what the answer to your questions is. To answer your questions no, it is not the gluon. It is in fact more similar to a proton. It's actually a type of meson particle and is made up of one quark and one antiquark. However, you are correct in that the gluon is the EP for the strong force. Cornell and Warwick published some good info on it if you're interested in more details. This is the decay analysis from CERN: arxiv.org/pdf/1407.7712.pdf
Thanks for your confidence in our knowledge Cameron, and thank you for answering her question!
cameron burchak Thank you so much for your answer! To be honest, I read the first 3 pages of the CERN analysis and I didn't understand much (I'm just a 1st year Undergrad)
I was trying to find online info from Cornell and Warwick you mentioned, but couldn't.
Is this particle is not the exchange particle, how is it involved in the strong nuclear interaction?
Alina Kuzmich Ok so it's not quite as simple as what I'm about to say but this is basically the idea: the strong interaction that is one of the "fundamental forces" mentioned in the video is referring to the interaction of the protons in the nucleus. These new particles (Ds3*(2860)-) are virtually identical to protons.The new particle is bound together in a similar way to protons (conclusively proven in the decay analysis paper). Due to this similarity, the Warwick researchers argue that scientists will now be able to study the particle to further understand strong interactions. The reason that it's so much easier to study this new particle as opposed to just studying the proton is that it is 3 times as massive obviously making it easier to identify.
Good luck with undergrad!
cameron burchak Thank you for your reply, it is amazing that you found time to explain it to me.
I'm actually studying at Warwick now :)
Good luck to you as well!
