"Simple! I began with a real image of the universe about 13.7 BILLION years ago..."
Simple.
+samthemagicianman well yes if we go google 'cosmic backround radiation' It would be right there.

Simulating the universe? No problem.
Simulating space itself? Try me.
Running KSP? uhhh
No man can accurately simulate the kraken.
which laptop would be best for a ug physics student in 2024 ? Budget is around 800 to 1200 USD. Do i need to expand my budget to get a long lasting device ?
@@jsjsjjsshw If you have a need for fancy simulations, especially as a student where you won't necessarily get to choose a good low-requirements simulation program, you'll probably need more money than that. I'd ask whatever program you're going into for their recommendation though, they might have taken stuff like this into account.
As for a long-lasting device...if you don't want to use it for much, any device will last a long time. Otherwise, I'd say that's about the bare minimum budget for a decent laptop that'll last 5-10 years with careful use.
@@ThePCguy17 I really don't have a wish to perform fancy simulation. I want my study and work to be done . Nothing out the world , just sticking around the course and curriculum. I may try pushing a little more research projects to strengthen my profile either for a job or grad school. I heard the windows device slow down significantly after 3-4 years . The level of computational load on my device will increase with time but if the performance starts to decline then it wouldn't be a good deal. 💀 What do you say about this ? Any suggestions of laptop if i push my budget by few hundred dollars.
@@jsjsjjsshw I don't have specific suggestions, but if that's what you want your budget is perfectly adequate. Do some research, buy something that doesn't have anything experimental or untested in it (which would probably be outside your budget anyway) and then do basic maintenance on your PC as it ages. Just a quick scan for junk to delete will usually not cost you more than 10 bucks online, and it does wonders for increasing the computational lifetime of a system that would otherwise slow down.
Aside from that, as long as you don't get any viruses, there's no real reason your computer shouldn't last you 10 years or more. The only problem is that by the time 10 years have passed it will be so unbelievably outdated that unless you're just using it for basic functions you'll probably want or need a new machine anyway. Because sadly machines getting full of crap as they age is only half the cause of slowdown, the other half is because the internet get massively more complex as time goes on so anywhere you go with especially interesting features will demand more of your machine than the poor thing can handle.
My mother, on the other hand, still has a laptop from like 2007 that she uses for personal accounting, taxes, and basically nothing else. It's not _allowed_ to connect to the internet because that's just not what it's for, and it will likely continue to work until its innards rust out, something I suspect will take quite a lot of time.
But can It run Crysis?
VintageLJ HA
VintageLJ nothing can
Bruh universe is not a computer a computer and run the programs but the universe
This may be the only thing that can
But what is Crysis anyway?
"So, how did I simulate the universe on my laptop? Simple."
yeah sure ok
Geniuses tend to think everything is simple. Sadly stupid people like me have no hope of understanding.
Also, stupid people don't have no hope of understanding, unless you're extremely stupid.
"How did I do this really difficult thing? Simple. I removed parameters until it was easy. Boom."
its incredible that density imperfections on the atomic level in the early universe have expanded and ballooned out to be density imperfections that are billions of lightyears across, the space between the atoms of our galaxy and those of the nearby galaxies could have once been planck lengths apart, and now these empty spaces span the entire cosmos. Beautiful.
Technically, my own physical laptop is its own universe depending on how you define it.
the millennium run looks eerily similar to brain neurons...
What if, and bear with me here, what if the universe we live in is the brain of someone/thing else living in their own universe.

Totally, I thought the same. I also read that the universe expansion resembles brain growth, or does brain growth resemble universal expansion o.O
+afroman9541 mind fucked
Will your laptop simulate Crysis?
Love it - Amazing stuff, thanks for posting it
(what I love most about both computer simulations is that in both cases, it required someone to press 'enter' to start the process)
And I am just sitting here trying to make a simple sand particle simulator in C++; This kind of shit is though.
Millennium Run:
10,077,696,00 particles, ran on 512 computers, over 350,000 processor hours (40 processor years) with 28 days of wall-clock time.
MinutePhysics Simulation:
1 computer, 40,000 particles, 15 minute setup, with 2 freaking processor hours.
Why?
+Xevamystic id imagine because as you add more particles it gets exponentially harder to calculate, as you have to calculate a new particles effect on all the particles there and all the particles effect on the new particle.
you have to remember that:
The gravity is not right
it is 2d
and 10 billion is a lot more than 40,000
I'm not clicking that link at the end... I'll get stuck in the loop again O.o
Don't forget to put Proffesor Fartsparkles back in his Time Nap.

Don't worry. I made one and recorded the output. It's on youtube, though it's unlisted.
Me too
@@froidesprit link? ;p
I really expected Space Engine. Free and astonishingly beautiful.
That looks cool. And it actually looks like a real galaxy cluster.
I did a similar thing in The Powder Toy (which is a cool game and it's free). It gave a very similar result.
Henry, you are awesome, never forget that.
But were was the bearded man in the 'sky' that made it all??? hahaha
Beyond the observable universe
Zaron728 that makes 0 sense

I didn't see the big bang either. because it's a simulation.
Depends on the religion

Please do a video explaining Planck's constant!! It'd be perfect for what you do!
The casual sound of hydrogen in the background
EDIT: Accidentally deleted 'background'. Readded it.
You have maybe the best chanel on youtube!
The first three links appear to be broken
Can anyone explain how collapsing matter (Hydrogen) turned to heavier elements and then complex compounds? And going further back how was hydrogen formed from known subatomic particles like electrons, protons, neutrons, quarks etc etc?
Great questions!
"how collapsing matter (Hydrogen) turned to heavier elements and then complex compounds?"
First the elements, then we can worry about the compounds. Heavier elements are formed mainly by fusion, which happens in the starts. In our sun, for example, two atoms of hydrogen (1 proton and 1 neutron in its nucleus) fuse under enormous heat and pressures to form Helium (2 protons and 1 or 2 neutrons)
Heavier elements are then formed when stars like the sun, run out of hydrogen and start fusing Helium into Carbon and other heavier elements.
I'm afraid that's as far as I go for now, if you're still interested I'll be happy to give you some pointers where you can learn to your hearts content.
Also, you can probably google your questions and find articles and videos that explain respond them better than here.
HTH
Hydrogen and Helium were made in the Big Bang. At one point, the universe was too hot for protons to collide and form He in what is called the "p-p chain". Instead, in what is called "pair production", the whole universe was a "quark soup" and quarks came together to form baryons (like protons and neutrons).
Later on, in stars, H smashed together to eventually form He, and He smashed together to form C, and this cycle continues with heavier and heavier elements up until Iron. Any elements heavier than iron are formed in supernova, particularly type II supernova.
Your videos are AWESOME man!
Vladimir Romanyuk worked on a space simulation in 2005, he made a public release in 2010, and currently is a simulation of bazillions of galaxies, gajillions of stars, and zajillions of planets, and jadillions of asteroids and other objects.

Universe Sandbox nomore2 is a bit different from what he's shown here.
Very well put.
How did you come to that brilliant conclusion?
if you pause at 0:51 i have seen exactly that while on hallucinogenics everything is starting to make sense
and how do i simulate it without a laptop?
*produces a rainbow over my head* imagination!
Ah, but where did he get the picture of the universe from 3.some-odd-billion years ago?
Vizthex scientists use it commonly. its called The Cosmic Background Radiation en.wikipedia.org/wiki/Cosmic_background_radiation
You explained that better than I did to a guy who had the exact same problem, not understanding that light isn't instantaneous.
so if you got a large flat electro magnet and a piece of steel fixed in place close together when you turn it on you could almost get the same effect
Thank you for that logical fallacy....what per se do you think happened or how the universe was created?
that particle pun >>>>>>
this video is amazing, and so the music by Jake Chudnow.
this song has a title, or has been composed for this video?
hope somebody knows, thx
I've gone through multiple comments telling me that Maria Jose Ayora's and my hypothesis was wrong, your the first one to call me an "idiot" and i appreciate your rant against me. I know where i went wrong and i did not know that the vcolume would increase during freezing. Thank you for using a vulgar language to correct me, you must be a shining star in the scientific, learning community.
Minutephysics, how much processing power would it take to simulate the entire universe particle for particle in real time?
Very cool demo w/ AE..
the music is so awesome
The Millenium Simulation ist the most beautiful simulation I ever saw.
The links in the description are all broken.
You're right, there's a logic progression of events following the law's of physics, meaning that things change following the laws of entropy and cause and effect. Time is not needed for this progression to exist, but is needed to give physical meaning to those changes.
It's interesting to imagine "erasing" all Plank units but ONE: The "you" on that frozen plank unit would remember the past, and so it would think time is moving, even though that feeling would be eternally frozen. Crazy huh?
It depends on how you measure it. Less density means that in the same volume of space, there is less mass, so if you calculate it by volume, then yes, 1 cm3 of ice weights less than 1 cm3 of water, but if you calculate it by mass, 1 kg of ice weights as much as 1 kg of water, but in this case, 1kg of ice occupies more space than 1 kg of water. :)
where have you been Henry?
You should do a comparison between the young earth Creation and old earth evolution theories
Hey Minute Physics, is the universe also rotating around its center?
I am blessed to have a friend like RegisFidelis
which laptop would be best for a ug physics student in 2024 ? Budget is around 800 to 1200 USD. Do i need to expand my budget to get a long lasting device ?
OK wait.... do photons dissipate or dissolve into matter or are they always and forever a photon? can you build a machine to detect photons and predict their travel just like they did the universe, thus creating a machine that can simulate the past so that i can watch dinosaurs walk around?
Bar galaxies have a trailing edge. The simulator doesnt seem to become brighter, and show how as the bar galaxy goes through a few thousand years. Would there be a way to reverse what a galaxy would have looked like a few thousand years back? and then go forward again?
i appreciate the links thank you very much
I got a question, What are some theories about if the edge of the universe will ever stop expanding? Will it effect earth if it does?
Aha, good question. The fact is that while the DENSITY of ice-->water is different, the overall mass changes the same. This is accomplished by the ice having more volume, since density is determined by mass and volume. Hope i could help :)
to us it looks that way to us because at that extreme distance a large movement is scaled down by said distance to appear nonexistent that is why we use the doppler effect tells us that the redder the light coming from those stars is the farther and faster it is away you know like what you learn in rudimentary science.
thanks but that´s my question. if there is the same amount of water, because ice is less dense then it will be heavier now but is it??
Oh thank you, I was under the impression thats since ice would float in water it would be lighter but i forgot that density causes floating, not weight.
if you freeze water into ice, you have before and after the same amount in weight.
but the ice will expand itself because it needs more space than water. this leads to the fact that for example 10 cm³ of ice will weight less than 10 cm³ of water.
so you might say that the earth was bigger during ice age, but didnt weight less.
I didn't know you worked with DFTBA.
Very interesting, though not altogether unexpected.
That's gonna be my new screen-saver!
How long will it take for consumer pc's to be able to run the millennium simulation in a reasonable amount of time?
uh yeah its kinda silly question. ice is less dense that water, thats why it appears lighter for equal volume of water. But over all the same quantity (mass) of water turned into ice. so no change in weight.
From what I've seen and read, it is expanding. (Seen as in, watching Nova and the Science Channel :P) Edward Hubble discovered this in the 20s. Could you please PM on CZcams a study of this? I would be so very interested! Thanks!
Jake Chudnow for the win!!!!!!!!!!!!
You do know there are parts of the universe where time literally stops. (assuming you can survive the devastating crushing gravity) But everything is condensed so much that time phsycially stop. a watch would stop running (once again assuming it would be able to withstand the forces pushing in on it.). Black holes FYI...
Anyone know the name of the song? Know the one who made is Jake Chudnow, but can't find the song in the video
What if we create an infinite Sim loop that develops to the point where it creates such a strenuous load on the original super computer that's running the first instance of the simulation that it crashes and the simulation has to be reset?
YOU'RE A FRICKIN' GENIUS
If you freeze the same amount of water, you get the same amount of ice. It is just the way water molecules bond themselves when they freeze, creating more empty spaces between the molecules, hence a larger volume. Since you increased the volume without increasing the mass, the density decreases, and therefore ice floats on water. Ice is not exactly lighter than water, it is just less dense.
What if I'm using a desktop computer? would it still work?
No, do not attempt it. I did it, and I created a miniature black hole. My bad.
Fertro you moron
Fertro Did you try to draw the power back out for a super badass battery? I hear those work really well in powering a planet or deathstar for many years.
tsutl84 I wish I did. I'm tempted to give it another shot, but I'm afraid I might inconvenience some people by ending their existence.
Ice isn't lighter than liquid water, it is just simply less dense. When water freezes it expands. It floats because it's molecular make-up isn't following the basic rules thermodynamics.
Please, explain how you would disprove the big bang and evolution.
You can, the explosion was due to the second rule of thermodynamics. The hydrogen masses start getting critical mass producing stars. Planets aren't perfect spherical, the rocks get together due to gravity, also, due to dark matter and interplanetary relations (orbits and other things) these massive clumps start to orbit the stars and then life depends on the distance to a star, water and resources...
Thank you! Yes! My thoughts exactly!
Simply Great
Perhaps I'm looking at this wrong, but the fact that things can indeed change means that there must be a progression, in the case of Planck states from one to the the next. In other words, the "movement" from one Planck state to the next is simply another way to understand time. You could expand the idea of Planck states to an analogy of seconds; each second frozen in time. The only difference is of course the length of a second vs a Planck second. Remember, our perception is our reality.
I hope so. I'd follow them.
depends on your definitions of "smooth" and "simple".
gracias, pero cuanto se atraería a la tierra (más o menos que ahora) osea habría la misma masa y más volumen, pero la misma "atracción" hacia la tierra?
i was asking if it /also/ rotates around the center. i understand the gravity-driven rotation. i meant, specifically, is there any rotation about the (possibly) mass-less center of the universe, the point from which all matter in the universe erupted?
I have no idea what that is supposed to mean, but it sounds nice.
Time is requisite for change to occur.
"Time is what keeps everything from happening at once." -Albert Einstein
I get what you're saying about being in a single Planck state. Back when I was in elementary school I posed the idea that each one of my past selves, defined by seconds, would see time as ending just as my next started. However, this is just a thought experiment, as the Planck second isn't long enough for anything to happen, save the separate creation and annihilation of virtual part
Very good!
How small can a planck be, before it ceases to be a planck?
What is the *min* planck ?
I'll take that as a complement, thanks :)
Which filter did they use? Rise? Or Valencia?
Makes sense why life is so rare in the universe. The programmer is still busy creating and troubleshooting the lives that already appeared here on Earth.
I ran a universe simulation program and now there's intelligent life evolved on one of the planets and I'm worried they may soon figure out their in a computer simulation. Also I'm starting to show symptoms of megalomania. What do?
This feature isn't available on some devices, making an '@username' the best second option. Doing this used to work (not in the far past, but the recent past), but CZcams removed that feature.
Can it run our universe, with human living and stuff we have?
is the map of the big bang page not active or is it just me that can't enter it ???
thank you very much. finally.
Ice is not light than water, it is just less dense; 1kg of ice weights as much as 1kg of water; and if you freeze 1kg of water you still get 1kg of ice (if you don't take in consideration any evaporation).
Very interesting.. I think space is everything, and time is like the film playing everything in a linear fashion. So everything that exists would be nothing without the constantly flowing time. And of course we might never get an answer to questions like "why do we exist" and "why does the universe/time exist".
You can actually predict very accurately how the universe in the beginning looked like since there still are traces of radiation left from the big bang.
can this simulation also spawn life? or to be more precise intelligent self aware life?
william112004 Yes, it can. You only need some life DNA and a powerful computer so powerful it breaks all laws of physics. Then, push a few buttons on Adobe After Effects, add a little gravity, and watch the life spread!
Try to think of it this way, a man running could be considered a force (i.e. the phrase "a force to be reckoned with") If a man ran against a bolder that he could not move, he could still apply pressure, but would be stopped. In your scenario the unstoppable force is still applying pressure, but is being stopped.
but how much does that mass weight, suposing that there is gravity and we could measure
What’s the name of the music used in this video
On the "the Planck second isn't long enough for anything to happen" thing, I think that even though within a Planck second nothing can "change", that doesn't mean that it's "not happening". Something IS happening, it's just that it's frozen during the Planck second. Even if the neural activity of a brain is "frozen" withing a Planck second, does that mean that the brain is not "concious" during that time? If we're not concious during the planck second, then when it is that we are?
