"When we finally move beyond Einstein it might be another singular genius that comes along,someone struggling in a poor school in Kenya right now that we don't know about..." Sean Carrol. As a Kenyan this is something 😅
You proud of it brother?
thats true,its just the power of a mind with with an idea
The director of the Institute of Advanced Studies in this video is really good at explaining the significance of those equations and concepts simply. Great communicator.
Does anyone feel like me that the reading voice is very soothing and it makes me fall asleep very quickly even though there are many new things I need to hear and learn?
Fun fact: Einstein's office in the patent office in Bern still exists and is in use .
Still daytime he should be working... was reading patents....
He does own research after works. And he was married..
That means he was very good with his time😊...
Many speculate he is adhd so...
Mileva organize a lot or also hv brilliant moment organizing?
But it is the wonders years of his😊
Being alone is key.

There is an idolatry around Einstein' s name.
Women weaken legs!
If this is true ... wait ... I see ;-)
Magnificent narration, A documentry for life. Bravo
I can’t even imagine how his mind worked, how did he manage to get along with his brilliant mind!
Definitely, his mind worked undistracted by things that distract us today. And he managed to get along with his brilliant mind by enjoying every minute of it.
It's like me watching Pakistanis fixing a truck, I want to try that. I see a different way of cooking fish or cleaning things with baking soda, I wanna try them too. Then I end up doing nothing at all.

LIGO measured gravitational waves in sept 2015 and announced them in feb 2016. And many more instances after the initial detection. So this documentary must be before 2016.
Albert Einstein's thought experiments are some of the most famous and influential in the history of physics. They were instrumental in the development of his theory of general relativity, which is our current understanding of gravity.
One of Einstein's most famous thought experiments is the elevator thought experiment. In this experiment, Einstein imagines an elevator that is accelerating upwards in a closed room. He argues that an observer in the elevator would not be able to tell the difference between this situation and being in a gravity field. This is because the effects of gravity and acceleration are indistinguishable.
Another famous thought experiment by Einstein is the bending of light thought experiment. In this experiment, Einstein imagines a beam of light passing by a massive object, such as the sun. He argues that the beam of light will be bent by the gravity of the sun. This is because gravity bends spacetime, and light travels through spacetime.
Einstein's thought experiments are not just interesting intellectual exercises. They have also been used to make predictions that have been verified by experiment. For example, the bending of light by gravity was first observed during a solar eclipse in 1919. This was a major confirmation of Einstein's theory of general relativity.
The problem with thought experiments is the results are just more thoughts.
good point.
Einstein's best thought experiment......I thought i farted but I really shit myself 🤪

Mindful? Every observation shows gravity to be a force between two or more masses🤦🏼♂️
Read his writings on human nature and how we ought to see one another. His insights into our minds and purpose are just as beautiful.
There are many thought experiments about time dilation that aren't just right. I think there's a part of the puzzle being left out and so we can't explain it without the missing part until someone finds it
19:43 , which time should speed up? Because there are two times , the body who is moved away or master clock time?. I think general relativity says( tells) the opposite
Great explanations. It helped me to visual in my mind more better. Thank you. Do you have chance to explain some differential equations in such easy understandable way? please also think about this. By this way we will have chance to go more deeply in an easy way. Thankyou.

Roll.
You do not sleep enough. Go to sleep one hour earlier and see if it helps. If not, try 2 hours earlier, but one hour should work, it is already a consistent improvement. Voila, now you have the theory you want, though it is not yours, haha :)

Cool, I can go further 👍
Very inspiring!!
Without wanting to detract from Einstein's merits, it should be known that almost everything was prepared for the creation of the theory of relativity, both mathematically and physically. The theory of relativity was hanging in the air, it would have been born in the 1910s one way or another. Many things had already been worked out that Einstein could build on. For example, the theory of "curved spaces" was completely ready. Several important concepts of relativity theory (time dilation, etc.) were already known by Lorenz before Einstein.
Undoubtedly, it is Einstein's great performance and merit, that he put the crown on the project indeed brilliantly. But it's the same in science as in sports, only the "gold medalists" are really respected. Lorentz, Minkowsky, Emmy Noether and many other excellent scientists did not receive the attention and recognition they deserved. Einstein was not at all as proficient in mathematics as many people think. Many matematicians helped him in this area, including his wife, with whom he was quite unfriendly and sometimes tyrannical.
Also, The other scientists you have mentioned like Lorentz, Poincare etc were not very clear with their own theory. They always had weird assumptions. But, Einstein was very clear about his work and intuitive deep ideas without any pre-assumption.

What I don't understand about the experiment mentioned at min. 40 is that there are, in fact, two opposite phenomena: on one hand, the time slows down while closing to the center of the earth, due to increase of gravity, on the other hand, placing the second clock to the top of a mountain means it moves faster due to rotation of the earth, which also should result in dilatation of the time. Why don't the two phenomena cancel each other out?
I feel that inertia is fundamental nature of the macro universe. Interactions bring about accelerations which manifests as the force of gravity. There's a difference between feeling gravity and knowing gravity. Newton felt gravity and Einstein saw gravity. Correct me if I am mistaken, I shall be grateful.

If he was so clever why didn’t he know the earth is flat
@@Kodakcompactdisc wdym? 😨
In retrospect, it seems so very obvious that the physical effects of gravity and acceleration are the same. The real genius of Einstein was to decide that if they feel the same, they must BE the same. The rest is just math! (But In this case tensor calculus - and I can tell you from personal experience that it is NOT easy!). Great documentary.
Nah it’s trash. Gravity is a force between masses. His theory is old pseudoscience propaganda

Our universe is just the brain of a human being. All the stars and matter are just like the atoms and electrons in your brain. Our time is just our concept and light is just the speed relevant to our matter. Traveling faster than light is possible, but you need to be bigger than the universe.
Fascinating!

Is gravity affecting time itself, or just the devices, the materials used in determining time?
Is gravity acceleration, or acceleration is just the effect?
Gob bless you PBS.

It's truly an amazing content!
Albert Einstein was a renowned physicist who is widely regarded as one of the greatest scientific minds in history. Born on March 14, 1879, in Ulm, Germany, Einstein made groundbreaking contributions to theoretical physics, revolutionizing our understanding of space, time, and the nature of the universe.
Einstein is best known for his theory of relativity, which encompasses two major theories: the special theory of relativity and the general theory of relativity. The special theory of relativity, published in 1905, introduced the famous equation E=mc², which established the equivalence of mass and energy. This theory transformed our understanding of time, space, and the concept of simultaneity.
so 'entanglement' is the time dilation between the object being perceived, in space-time... from the moment you look at it, to the moment you look away? 🤔
Where is the link
Why isn’t his most famous formula not discussed here? E=mc²
John Wheeler famously said: "matter tells Spacetime how to curve, and Spacetime tells matter how to move
That paper and ant anology is quite good to portray curved space time😂
THANK YOU...!!!
That orbital diagram at 28:40 - is that how it works? A Newtonean orbit would have Mercury repeating exactly the same orbit each time unless interfered with by outside gravitational effects (eg other planets) - but as I understand it, Einstein found that the irregulartity ist due to relativistic interference in the orbit. The animation shows Mercury's orbit making a tighter turn at aphelion (closest point to the sun) than it did on its last orbit, so that the perihelion (the point furthest from the sun) moves further counter-clockwise in this diagram. I was under the impression that mass of an object increases with speed, and with greater mass at aphelion (closest to sun, at greatest speed), it would have greater inertia and consequently more resistance to change in direction, hence it would make a more relaxed turn at aphelion rather than a tighter turn, and the perihelion in this diagram would move clockwise.
Did I get that wrong? Have I misunderstood what causes the orbit not to repeat exactly?
Spacetime mean : whatever we calculate and measure is right( is accurate) for a while, soon will change. Therefore is used their concept : spacetime
Everything pulsate like the heart,,even then universe too ( pulsating theory)
Legendary
PicoPhysics: Einstein thought process was hampered by then prevailing concept of space. When we consider the prevailing concepts of Space and Energy - While Energy was conserved (Allowing neutralization as well as change in form); space was constant, rigid and unaltering. In PicoPhysics a new concept Konservation (Conservation without Neutralization) is introduced as defining characteristic of Kenergy, While space is considered to be Non-Conserved as its defining characteristic. The relationship between the two is defined by Unary law "Space Contains Kenergy". All observations on the universe and laws of universe in Modern Physics can now be seen as a derivatives originating in Unary Law.

Albert einstein a great motivation 💯
"Our Universe", after the big bang, is a location in a Euclidean flat infinite 3+3D space-time,
(before the big bang, flat, infinite, without matter, without the flow of chow, without
expansion, how else if it is infinite), it is the final location that begins-occurs with the big
bang, which is not an explosion, but the change of the previous state to the subsequent state,
to the state of plasma, which is an ultra-high curvature of the dimensions of two quantities,
space-time. It is a boiling vacuum, it is a foam of dimensions, i.e. an extra curved
environment; that is, it is a finite location in an infinite flat time-space that "floats" in that
basic Euclidean network - a grid, a wonder of non-curved dimensions. This basic "web-yarn-
grid" in the state before the big-bang is still around us, it exists not only before the big-bang
but also after it, it is around us and we and the whole complex universe with matter and
galaxies and black holes and gravitational fields, we float in that flat 3+3D web of spacetime.
The beautiful thing is that even a mathematician will be amazed when he doesn't have to
investigate "how" big is the singularity = "locality-our Universe" and will have to recognize
the possibility of proposing reality, that in an infinite 3+3D non-curved space-time there is a
finite location arbitrarily large , is almost-infinite and almost-zero... Not even mathematicians
can determine how big a "unit" is - a unit interval of length or time in an infinite grid-net-yarn
of dimensions. That Location is "our Universe"...only one. No nonsense like “multiverses.
And the Big Bang was not the creation of the Universe "from nothing" (as string theorists
claim), but it was "jump = jump change of state" from previous to subsequent, "jump" from a
totally flat space-time to a totally curved state of space-time. The pre-Flag state of flat
dimensions suddenly changed to a finite location ( unknowable how big ) with extremely
crooked dimensions that 13.8 billion years unpacking !!!!, a) they unfold, not expand into a
global "real-structure" (the sky full of galaxies and everything we see "floats" in the variously
curved dimensions of every location we see) and b) they are packed !!!!in the microstructure
= in the microworld into matter !!!!, they are packed (those dimensions) after the big bang
into packages = elementary particles and they are further packed into conglomerates, i.e. into
atoms, molecules, into compounds chemical-biological. Etc., etc....etc., as I have described
elsewhere for many years. According to physicists from Di Valentino's team, this anomaly
could be explained if the expanding universe had a spherical shape. Which is the same, even
better, if the expansion is explained by the "unpacking" of that "starting" curvature of the
space-time dimensions in the Bang = in the stop state in which time begins to flow and
expand = the space and time dimensions begin to expand; this state of space-time of ultra-
high curvature of the dimensions of time and length, is plasma, is a state of post-Flash plasma
foam. In this foam, the "boiling vacuum" on Planck scales are recruited by warping packing
mini-localities = "frozen states" - waveballs-wavepackets that become elementary particles in
our human concept, packets that manifest themselves with properties such as mass, spin,
charge, etc., etc. (Each particle has a different number of packed dimensions and a different
curvature of these; this determines their properties). Then, such an initial state of the
Universe, the space-time after the Big Bang, expands further and further and simultaneously
collapses, expands "out" "of the singularity" and collapses "into itself" into matter. That is,
there is a clustering of elements (mass particles such as quarks, leptons, then on baryons,
resonances, then to atoms, then to molecules to compounds - that's "packing" crooked
packages into more complex conglomerates, and this happens not only after the Big Bang, but
the packing still happening today; complex mass of protein, DNA.. We still have a Planck
vacuum around us today, continuously throughout the history of this ! Universe..,, all around
us in the boiling vacuum of planck and sub-planck scales, are happening the same marches as
a million years ago, as a billion years ago, and 14.24 billion years ago right after the Big
Bang. This entire "Local Universe" with curved dimensions is nested in a 3+3D grid, in a
network of flat Euclidean dimensions. The universe "floats" in an infinite flat space-time. And
at the same time, unpacking...and packing is also taking place from Třesk. What type of curve
is that the unpacking is for the global version, I don't know, and I thought 35 years ago that
this unwrapping is parabolic...; Summary: it means that the Universe is expanding, sorry,
unfolds not only (!) after the Big Bang and after the era of relic radiation, but still, to this day,
all around us ( gravitational curvature is still around, unwrapped, other curvatures,
electromagnetic, etc. there are still commonly .., only the most "global" 3+3D space-time
field, gravity, is the most expanded and it is immeasurable how much-little the curvature
approaches absolute flatness- straightness.
Sir Isaac Newton was his inspiration.
If Einstein is right then 9/11 needs a new investigation where matter loses weight when falling in acceleration. NIST WTC FAQ 31 says the twin towers fell almost in free fall from the weight. 100% free fall is weightless.
no he was asked about it, it was Maxwell not Newton
He was not inspired, He was Curious.

Glad we did, but we all have sort of got it for a long time, just didn't have the words. :) Einstein could express this in everyone's favorite language Math. Why now, why him, why this. I do a lot of System Analysis, did he nail something, others haven't and couldn't disprove, not devoid of electronics/computers in my life. Somehow, you feel, like he is a Kin. Hertz, preceded him, Tesla pushed. Not we have Ethernet/TCP/IP. But he was looking at fibre, Star Trek, ahead. Just cool. Also thanks to Gene Roddenberry. E=Mc2 (under debate again) or Patents. :) Seeing hints of Genius here, pushed on, versus the naysayers. :) Patent office job, would have been an ideology, imagine, the popular. :):( Damn Apples (love how geeks think). Mr Newton (No Quantifiable light speed). Perhaps Einstein should have been a Mestopian. Now we are learning no absolutes, again. Kind of handy at the time, when they at all levels wanted absolutes. :( :) We get to the nuclear bomb and a small chance it might do that. Science must. 1930, The Great Reset. And the theory of Friction, no matter what. What creates zero friction? Not ever mentioned here? In space in a Vacuum? And.. Is that perhaps dark matter too, versus.. Friction, is a part of acceleration. :) If we are traveling at light speed do we have no friction. Fiber optics suggest, No. You have said gravity up not down, so overcome friction. Answers here always appreciated, now life turning upside down again. For me Engineer in ICT. :) I know they did the maths in reverse for electrical. :) No one would stand up like him each week and re-write. Especially with corporate input. :( :) He was No One SpEcIaL. Like Turing now, where to from here versus the Hubris. :) Small undertaking understanding the universe, whilst most don't even understand themselves. Science eh, hard enough to have a job and be human these days. :( :) First law in modern European law a time law. So this clock, could be worth billions. :) If people have that sense of humour. WARP SPACE. 41.04, plus the six minutes we get stolen everyday. :) Just another day. :) Love how GPS, now knows when I hop out of car, bullets quicker that way. :)Disney, we will find a way through the black hole, just all about what we push out. :)
