Einstein's Theory of Relativity is flawed because it is based on one's sense of vision. Light is an electromagnetic wave that carries packets of information about an object. The farther away you are from an object, the longer it takes for that information packet to reach you. Since we are living in the present, everything we see, we perceive to have happened in the present. Because it takes time for information to propagate the distance between the object and the observer, ( at the speed of light or the speed of sound) we experience time differently from someone else. Time propagates through space at infinite speed. It is the same time everywhere in the universe. When computers communicate, the data packet has a timestamp embedded within it, so when it arrives, it can be sequentially ordered based on when it was created. Unfortunately, raw light waves don't contain timestamps and our brains are not programmed to adjust for distance So two different people will experience time at different rates. Two people, standing side by side, one sighted, one blind, are watching lightning strike a tree. One sees the lightning strike the tree before the other hears lightning striking the tree. We experience time differently based on our senses and distance from the object. When the observer is in motion, it just takes longer/shorter time for that information packet to reach the observer thus it makes the observer feel like they are traveling in time.

I knew about spacetime before watching this video. This explains 60% as some points are missed. You could throw an example on lightspeed. Like the twin paradox where one of the twin travels to space at speed of light, returns to earth and sees that his sibling is old. And the curvation of spacetime was just tip of iceberg. Matters with much quantity of mass can distract spacetime and cause a time dialation. Anti matters can create a warmhole. They could be more described as Kurzgesagt did in their video. Overall not the best presentation but still good enough for newbies.

that's not the twin paradox, the twin paradox is this : suppose there is two twins on earth, their age is exactly the same twin B sees how twin A is moving at 90% of c from him away twin B sees himself to be stationary, and it's twin A who is in motion however... twin A sees how twin B is also moving at 90% of c from him away [in opposite vector of motion of twin B is measurement in relation to twin A) twin A sees himself to be stationary, and it's twin B who is in motion at this point the two twins shpuld have been both getting younger in respect to themselves, each, this is the point where many people give up and they think the special relativity is nonsense but it really isn't because of lorentz transforms that are explaining perfectly how "time dilation" really works and that there isn't any paradox in special relativity at all

​@@dkeffectdetector8920I just think in your way

The light doesn’t bend around an object. Light strikes the object. The light that bends is the light that would be just passing the surface of the object. Remember all objects in space are in motion in various directions at once. They move forward but also spin and spiral. When the light just misses hitting the surface and passes by, a distortion is created. We aren’t capable of filtering light waves completely. We are seeing multiple waves at “once” as they clump and spread as they pass the moving object. What we think of as bending are actually waves just before and after they strike the object. The wave never stops, so we see it as a distortion. And we are also seeing various waves being effected at “once”. This creates an illusion of light being bent. Now there are things that can bend light like water and such. But we see behind and object, because simply put, the object is moving out of the way. Also if as water can bend light, and atmosphere or crystals in orbit can also bend light creating an illusion of gravity bending light.

I’ve heard Sean Carroll and Brian Greene talk about us arranging to meet somewhere, and how it’s not enough to say where, we have to say when, which is the time part of spacetime. Does it make sense though, for a physicist to talk of space on its own, in certain contexts, and to talk of time on its own, in certain contexts?

Space, time, and space-time are three separate entities. True, they are inextricably linked, but they have unique properties. The time dimension is immutable, meaning it does not slow down (within a reference frame). Space is what is effected by time dilation, and that is based on your speed as you move through it, and/or experience gravitational forces. Most notably, it is only when the two dimensions merge into space-time due to being subjected to an interaction with a secondary frame of reference that the effects of time dilation are realized. Dilation can only effect space-time, not time or space.

So very interesting

space time is a geometric manifold based on cartesian geometry cartesian geometry is described by dots (literal dots) where each of these dots is treated uniqually, and where a set of these dots is creating certain geometric line (wordline) so yes, in space time you are represented as a dot a dot is representing an event in space time, so you are an event in space time, you are happening [no objects but events in space time] event is a certain position of yourself in vector of space during an instant of time so now you can see space time is not real as an actual natural phenomenon, space time is a human invention, a geometric diagram that is trying to explain the relation between the relative [virtual] motion and the speed of light [the true motion] space time got invented, or better said worked out in 1908 by minkowski so no, einstein didn't come up with the idea of space time, einstein ridiculed space time initially until minkowski proved him wrong, and then einstein used space time in general relativity, although the idea of space time is entirelly based on special relativity einstein didn't come up with the idea the speed of light is a constant for any observer in any reference frame, this got already described in lorentz transforms without which the special relativity has no sense it's not true the faster you go the slower the second is lasting for you, it's actually in different way because you percieve your second to be lasting as usually at any speed, at 1 mph or 99% of c you see your own second to be ticking the same but it's always the outside observer who is measuring a different tick of your own second in relation to his own second, or in other words the outside observer is measuring a different amount of space for you than you are measuring for him, this is actually time dilation or better said space variation because the faster you move in relation to the speed of light - in relation to the outside observer the more the space is contracting around yourself meanwhile the outside observer sees more space for you and it's you who is getting contracted in lenght but not the space around him [the outside observer] you travel at 90% of c in relation to the earth observer, you travel to alpha centauri the earth observer is measuring 4 years and 5 months for your journey you are measuring for yourself 8 months this is because your relative motion in respect to the earth observer, was much closer to the speed of light than his own relative motion was you literally cut off 6,5 times the distance between the earth and alpha centauri by your relative motion, you compressed the space between those two "way points", it is as if you were travelling at 5x the speed of light in respect to the earth observer so your relative motion in relation to the speed of light is " creating" space

There's a problem with time being affected by the quantum field (which it is, as evidenced by black holes for example)- if time is an aspect of spin, a vector, say, -within- the universe, it cannot equally be a boundary of said universe. Else, it would be much like attempting to contain water within a box made of water, where time as a universal constant would not remain symmetric within the universe via its own inconsistent structure. It seems as though time as we classically understand it, and the time understood in space-time, should actually be two different things, unless time is a fundamental part of the quantum field itself.

This time is your favourite Space-time Thou art you if then that time is also your favourite this time

Incidentally, I was just updating my WuTube app and reading the “What’s new” breakdown for version 17.36.3 and it says “bug fixes, stability improvements, repairs to space-time continuum” What’s scary is, I don’t think it was meant sarcastically, or some “witty” attempt to be humorous 😳

Space interacts with time as in objects in the spae interact with other objects in space. Why then is space considered to be the same as time?

¿ alguien puede explicar espacio y tiempo si no comprende un simple experimento de espacio y tiempo ?

Yes believe I got now spacetime expands thru an object mass at 300M meters per/sec weak attraction force generated by objects mass interference or resistance to expanding spacetime, attraction force directly proportional to objects mass.

Why must we accept explanations that we do not understand as truth? Einstein said if you cannot explain your answer clearly then you probably don’t understand the question. What is spacetime? The fourth dimension consists of 4 vectors. The ‘volume’ (sorry I do not know the 4th dimensional equivalent word) is expressed as length * width * height * time. Any questions?

The trampoline model of spacetime distortion as the source of gravity is not good. It relies on gravity itself! The force causing the attraction of the small ball to the big ball is just a component of the Earth's gravity force. A better explanation is that, with time, points in spacetime always migrate towards an object. Therefore, if I hold an apple "here", then two seconds later is no longer here. In fact, "here" has moved toward the Earth, and my holding the apple is, in fact, nothing else but pulling it through the dynamically distorted spacetime. Therefore, "here" always moves "there". If you leave it "unsupported, " you allow it to stay in the same place. This place in spacetime moves towards the middle of the Earth. Again, supporting something means dragging it through the spacetime.

This was so vague.....

Mass tells spacetime how to curve - More accurately, energy informs spacetime how to curve. Mass is an object of energy (momentum, pressure, sheer stress, density), but light also create spacetime curvature - because of its energy properties. Spacetime tells mass how to move - More accurately, spacetime describes the environment through which mass or light will travel. The pathway through this environment is dictated according to how mass or light is moving (direction, speed). Light is affected by gravity: No it isn't. Light travels in one direction only along the pathway dictated by spacetime curvature - See point 2 above. Acceleration causes gravity - No it doesn't. Acceleration is a variable of movement. A modification of movement will modify the path of travel according to the spacetime curvature- see point 2 above - acceleration emulates a gravitational effect but it does not cause gravity. Acceleration causes gravity - addendum - Energy causes gravity. Acceleration of mass (momentum, preassure, sheer stress, density), is an expression (application) of energy.

Hermann Minkowski originated the notion of spacetime . Einstein applied his theories of relativity and gravity to the concept

3:25 You are being pulled by the center of the earth, towards it.". ...I don't understand this, what grabs me? What is the "rope" that does the attachment / pulling? If the "rope" was visible, what does it look like? Does gravity pull? Does space push? If space pushes, it pushes harder on larger masses? Is the gravity rope bigger for bigger masses? How would it look different, if it could be seen? ... I don't understand these concepts.

If space was distorted every time an object manmade or not entered it then there would be no way to calculate time or distance or mapping of any objects including planets n moons

I like how they have improved Einstein's hair in this cartoon. Usually he looks like the man who DIDN'T invent hair conditioner - but should have.

Isn't spacetime and time and space all different Space is spacial dimensions and time is temporal, we exist in a 4D world 3 spatial and 1 temporal, This video is a good introduction to spacetime but doesn't give much of space and time. (Also when you think of higher dimensions you would think of just 1 temporal till the 13 i think which has 2 temporal dimension, i can't remember) Spatial dimensions are our 3D world and where we move and i like to think of temporal, the 1D time dimension as when we move

to be honest i still dont get it at all. Like why are time and space interlinked? Why would travelling at the speed of light make time move slower for me? Like is it that if i move faster all other things would appear to move slower for me because if thats the case then it still doesnt explain how is time relative its just that motion of everything is relative except for light because we have nothing faster than light but hypothetically if we manage to get a particle to move at a speed faster than that of light, then motion of light would be considered relative and the motion of that particle wouldnt be relative, then why the heck would time be relative if thats the case? like from what i could understand its only telling about relative motion of the particles, where the heck do space and time come in? and if i were to project an ray of light and hypothetically manage to move at the speed of that photon then wouldnt it mean that light is at rest for me? THIS IS SOO CONFUSING PLEASE SOMEONE EXPLAIN I BEG, I HAVENT BEEN ABLE TO FOCUS ON ANYTHING ELSE BECAUSE THESE QUESTIONS HAUNT ME AND I TRIED TO SEARCH ON QUORA AND GOOGLE BUT GOT NO ANSWERS

That's a meaningless question cause any object capable of 'seeing' cannot travel at the speed of light.

Time and space may be connected but who says it can't move backwards as well as forwards just because we've discovered one way.

That’s another theory… human brains just observe it moving forward😊

New information revealed! Einstein ALWAYS skipped leg day.

If Newton and Einstein have their mathematics, I have mine.

I love the videos! I debate in my mind the reasons why we lost so much since einstein. But so happy to see more and more intelligence on line, in the eyes and hearts of the people on earth. Much appreciated

What exactly is space-time? It was a question... what Newton says, what Einstein imagines, black holes, the speed of light, etc, etc, and finally another one who doesn't know what space-time is...

I was going to ask about that.

Simple words !!! 🤔

You didn’t explain how space time forms why is space time where it is?!?! You just defined some definitions 😅😅😅😅

Maybe distortion is not the most exact word.

Space aur earth ke ghadi same time dikhati hai Usko kya pata ke ye earth hai Ya space.

the earth rotates on its axees? in my world the word is axis. how about explaining time which is the subject.

bro how did your audio get WORSE from 4 years ago?

Still doesn't explain exactly what space, time and spacetime are. Just regurgitates the same word sets everyone else does. What is the proof that space is actually something and not the nothing- at-all in between all the something? And what is the evidence that time actually exists rather then just being a way of describing change in the infinite instantaneous "now"? Can time be detected and observed in and of itself??

Wasn't Maxwell the one to first prove mathematically that speed of light was a constant???

I think that's correct.

'Time' was invented by man - it is a defintion/concept so quite simply you can't make it connect with time in any physical manner. As a definition you have to decide on a time standard - lets' say GMT. Now any observer, anywhere, doing anything HAS to use GMT. It isn't different for anyone - it can't be since it is a definition, a simple statement that we all agree on - perhaps supported by our reference clock which will simply state - it's 2:14. THINK, all SI units have amplitudes that we can vary and measure, so we can measure say 3V, then vary it and we might measure 2.7V, same with mass, light, pressure, etc. Funny then that you can't do that with 'time'. Time has NO amplitude, you can't vary it. People, you have to see that while time is useful, it doesn't actually exist, in the same way that Santa Claus doesn't exist.... This theory needs rethinking, it has lost its way.....

This is not an explanation of General Relative.

@@Scienceabc Add me to that column. I still don’t understand. Space time is some kind of combination of time, speed, gravity, mass, and a trampoline. How do two spaceships going the same speed have a different sense of time? Were they on different areas of the trampoline, therefore being unknowingly also sped up by the gravity of the bowling ball? How would that increased speed not change their separate speeds like flying into vs along with a strong wind? Yeah, I’m in the “”I'm trying to understand, but I still don’t get it” column.

/\ THIS How does something maintain an orbit if it's spiraling inward due to spacetime, let alone have it's orbit get longer AKA the moon? Why does this example only work because gravity is pulling everything on the trampoline to the lowest point? Is the fabric of spacetime a flat plane? How can that possibly work in our 3 dimensional universe where even the planets in our own solar system don't rotate on the same axis?

Gets close but it is not a simple explanation. More confusing than explaining.

Thank you Andy! Very profound lol

Consider the velocity of Light as an instance or impact. That means in one second (instance of human control of time) the particle in the Light hits an object some 300,000 KM away. This way of thinking solves the problem. Time does not exist in this Universe. It is only the Speed or rate of activities happening in this apparent Universe hitting the Sense Organs which actually matters to human beings.

Please don't use the phrase "simple explanation." I'm still having a hard time understanding 😮.

This video is unclear and confusing.
