03/01/2025 - 3:11 AMapple didn't fell. Newton's body brought from that from tree. Great ….. thanks Newton for giving physics without any reason.

03/01/2025 - 3:11 AMThe description at about 6:00 minutes is an incorrect description. It describes two people walking on the earth and says their paths will cross because of General Relativity. Not True! It’s because they are both walking aimed at a single point/position in the universe. Of course they get closer. If two people in an otherwise empty universe both aim at a single point in space with nothing else nothing interfering, they will ALWAYS get closer until they meet.

03/01/2025 - 3:11 AMwhy does this doesnt affect larger planets, i mean why arent we pulled towards it since its more massive than earth?

03/01/2025 - 3:11 AMUniverse cant be smooth.It has to be like rock because the expansion rate is not same everywhere.

03/01/2025 - 3:11 AMWe proceed are world from 3 dimensional view, this distorts are abilities to see black holes are input information hubs and we basically are information about to be collected . And are solar bodies,,,are sons are output hubs or loops of compacted information for a larger perspective in reality,,,this is are universe!

03/01/2025 - 3:11 AMThis is my fav video of general relativity. The explanation and visuals make it so easy to understand and imagine

03/01/2025 - 3:11 AMA spinning earth would have a spinning gravity field
As a satellite falls to the earth its trajectory would be curved due to the spinning gravity field
That illustration does not disprove gravity

03/01/2025 - 3:11 AMAT 11:10 This happens because darkness is the absence of light ≠ the presence of light is the absence of darkness. Light 1 sec = 10^0 ♾️> 1 deci = 10^-1 > 1 centi = 10^-2 > 1 milli = 10^-3 > 1 micro = 10^-6 > 1 infi = 10^-0 ♾️ Darkness. Where light is present it = 1, and where darkness is present it = 0. The universe is a binary system of 1’s and 0’s. A SMALL space of vacuum has less mass than a LARGE space of vacuum. The farther you are in the void of vacuum where ABSOLUTELY no light is visible you are not influenced by any gravity and time for you is 1 infi second = 10^-0 and you wouldn’t be even able to move. But if you’re in a solar system then you are influenced by gravity where light is present then time is 1 sec = 10^0. NOTE: THERE IS NO MASS IN THE VOID OF SPACE BUT THE VOID ITSELF IS MASSIVE COMPARED TO THE TINY VACUUM OF SPACE WHICH WE INHABIT.

03/01/2025 - 3:11 AMThe Universe. How is it here? Why is it here? Where did it come from? And where will it go?
Answers to these questions in the next video.

03/01/2025 - 3:11 AMWhen the tensors of Newtonian mechanics are considered to be first-generation tensors,
Tμν is flat geometry,
Euclidean geometry is a naive, childish geometry, and the 4-dimensional tensor is diag(+1,+1,+1,+1).
This ημν =diag(+1,+1,+1,+1) is assertive, and in the present it seeks stability, and the space-time is static from the present to the present, and the arrow of time tries to stay in the present. It's really selfish.
When the Lorentz transformation is performed,
two tensors appear.
The second-generation Tμν,
the third-generation tensor Tμν are obtained.
ημν =diag(−1,+1,+1,+1),
ημν =diag(+1,-1,-1,-1),
The arrow of time in space-time moves from the past to the present and from the present to the future, and the other one moves from the future to the present and from the present to the past, and the arrow of time moves in that way.

03/01/2025 - 3:11 AMThank you so much for creating these visualizations. Without them, I would never have tried to understand it!!!
@kazukiyuki9233
03/01/2025 - 3:11 AMI have a question, here he mentions that when a object is travelling through space in a straight line, when is encounters a massive object like earth its path gets curved, because the earth curves the space around it. But my question is that if an object is not moving in straight line, its stationary and not moving, why does it still get attracted by the curved space around earth. the curve space around a mass tells how a object moving in space should move, but if the object is not moving then what. Could anybody pls explain this to me??

03/01/2025 - 3:11 AM6:00 then wouldnt standing still relative to the masive object not have any "line" to distort?
@mayoraeryn
03/01/2025 - 3:11 AMI'm kind of curious how close someone could get to a black hole while still being able to escape. Just imagine it, we develop warp drive technology, send a few humans off into the direction of Saggitarius A, have them orbit it for 10 minutes, and see just how far into the future they have traveled when they come back. Would be pretty interesting I think

03/01/2025 - 3:11 AMthis is easily the best explanation of general relativity on youtube. did not learn this in high school lol
@nawaljunaid6294
03/01/2025 - 3:11 AMif falling is basically the earth moving towards the object, would the earth eventually crash into the sun, because wrt to the sun the earth is in free fall?
