Why is it only bending in one direction because there's no up and down in space?

This spacetime thing and time dilation doesn't exist at all and it doesn't make sense at all no matter how much you try to explain it. It just doesn't make sense at all

More so that time changes gravity

But in fact light itself doesn't experience time,if in that visualisation light bends it always moves with the same rate 🧐 and does the curved space time decrease light's speed?

Explaining Gravity with a trampoline on earth which acts like under it gravity acts is not the right way to explain this imo. If there is no gravity objects won't fall to that bend. You should explain this in 4 dimensions even if it is more complex

So you’re saying that because the light has to bend, time slows down for light?

You explained how, but not why.

You can also think spacetime as a soft mattress, you can put a ball and it will bend the mattress

"Slowly" time relative to who...!!! Relative to obiective time and only real time... In conclusion time dilation is a illusion...is not real... Slowing down biological or mechanical processes does not mean dilating time... This can be done with other methods as well ...,for example cryogenics. Einstein SF writer ...not true scientist !!!😂

Time dilation =illusion😅

This is probably a dumb question, but I’ll ask anyway. Is this why we are finding that the universe may be older than 13 billion years? Is it 13 billion years old only according to us on earth but it may be shorter or older to objects that have more mass or speed? This is a genuine question please don’t just tell me I’m an idiot I already know that I’m just trying to learn more, this is such a mind bending think to ponder to a simpleton like me

it's not gravity but mass that changes time...

What is time ? ​@@Sir.BlackHole

Absolute space is now correlated with time which causes more trouble than its worth for public education systems. Prescription of time granted deterministic simplicity and treated as physical realism is fine for mapping but its really a belief system that drives this notion of time but refused to separate the concept of Longitude and latitude.

Better to think about an apple under water . Where you envision earth epoch of vision. where space should be at the center of earth is now pushed out on the surface where we stand and feel earth pushing us into space curvature. By product build up of curvature.. Trying to draw a horizontal evolutionary time line story line on absolute space is what really causes so much confusion. When we only speak of epochs with super position marks to envision our perspective of mind it works better. But as you all know deep time evolution is extremely protected no matter how much complications it creates in young minds.

Explaining gravity by gravity😶

Space doesn't bend, time slows down. Space is a consequence of time. Einstein was close. Hawking proved what i said. Hawking radiation is how black holes "lose mass". Gravity is what we see with our caveman eyes! Mass is energy condensed, time is slower for condensed energy like a black hole being nearly imperceptible! As a black hole reaches the end, it is much hotter and isn't resisting time as much. Time is the typology of of Space. Imagine the formula for horizontal motion, you ignore the vertical velocity and see the horizontal velocity. This is why we see light bending and lensing around massive celestial objects. Different frequencies of light move at different rates trough a prism and are moving at different vertical velocities becoming obvious as a rainbow 🌈

This is not satisfying for me, this presantation follows the logical of Newton's theory. Why does the apple fall on sheet of fabric? Because there is a force pulling it down.

Maybe. But you’d have to be close. Technically we’re close to the sun and not sucked in. Asteroids and meteors pass between us and the moon without getting sucked in.

I dislike this demonstration. You're using gravity to explain gravity

Time is simply when you experience particles such as light heat or matter hitting you but if you move faster than the fastest particle aka light you will escape every particle and thus never experience them ( time travel )

Imagine that you just space out to the planet that rotates 200 miles per hour and bigger than earth.you live there for earth time 24 hours and back to earth and ask the stranger and he tells you it is 10000 years now bruh..😂

@@Sir.BlackHole yes, gravity is a result of the curve, it is not causing the curve. And while it’s correct to say spacetime is warped, I’ve always thought there was a better way to say it. Mass causes a DRAG on the flow/stream of time (similar to but not exactly like a large rock in a stream), and so objects further away from earth pass along and age at a quicker relative rate. It is this difference that causes the funnel shape we see in diagrams, and thus causes things to fall into earth from all directions since the funnel is 4 dimensional. Space and time are undoubtedly linked but it always kinda irks me when people regurgitate that it’s just spacetime warping since I feel like it leads to inaccurate understandings

So when you say light bending, is that the same as when light bends through prisms or through water for example or is it a different kind of bending or is it the same vending, just happening with a different principal?

Thank you so much for this video! Simple yet made it so much clearer to me, really useful!

Absolute nonsense. Initially time was the left/right direction in the plot and space was the up/down direction. Then you said if you place the earth there it curves spacetime... okay fine. Then the pencil and the apple move toward the earth. The pencil moves back in time to where the earth is in spacetime? I know these depictions have always been super unclear but this has got to be the worst one I've ever seen.

Who hurt you? Who made you invert the check mark?

How is it going to fall indeed if you dont define gravity as a force Nice try but wrong explanation

So you're saying gravity changes time because gravity changes time?

A perfect loop doesn’t ex-

So, whose time will be affected? I mean, do we tick our time in function of light or in function of a well known number of oscillations of a crystal. Why will a watch be delayed based off on a light beam? Is there something I don't get?

Its not time itself thats ticking faster or slower. Its just objects moving faster or slower. The correct word to use is duration, not time.

ok but why tho?

So like on earth there is sometimes a small dip that is not flat at the bottom not giving the objects going down to retain the same speed it had when it was on top, then we have it going up with something that is not mechanically made or operated like a bowling ball which will be light for this example, the bowling ball also known as light in this example is not mechanically operated so instead of retaining its former speed it will gather the speed from the previous down fall it had before, 5hink of it like a gush of water, using the momentum and force from the down fall previously it will go up using the momentum from the down fall gradually decreasing like a stopped car loosing it's fuel to the point where when it goes back up it will have the same speed it had before when it wasn't in that dip

I don't understand how time is connected to light or the speed of light. the time became slower if the light became slower ?? I see light as an object a high-speed object and time is untouchable at least by a fast thing.

@thatscool7877

Time is connected to the speed of everything. To see how fast something is, you have the distance it needs to travel and the amount of time it takes for that thing to cross that distance.

Since light bents due to bent of space time curvatureby massive objects Is that mean, than massive opaque object can't produce shadow??

Space is the most boring trampoline if no one is jumping

Similar how wind travels above and below a planes wing to give it lift .. i can't remember the name given to the process.

Physic really need to correct this error in real-time isn't effect by gravity, the tool we use to measure time is effect by gravity. IE light ben or space ben, this means the device is used measure time is an effect, not that time itself is affected.

You have no idea what you're talking about. Physics doesn't need to "correct" an "error", you just don't know anything about physics. Space and time are fundamentally warped, as a direct consequence of the speed of light being constant, regardless of frame. If space and time were not warped, the resultant speeds of objects from different reference frames would be a simple vector addition. This describes a flat, Euclidean geometry. It would mean that, if a car travels at 0.6c and launches a projectile at 0.7c, the resultant speed as observed by a ground based observer would be 1.3c. But we know this is wrong because nothing has ever traveled faster than c, regardless of the reference frame. The only way the speed of light would be constant is if time and space were adjusting in different frames to account for this. The reason that the "devices" we use to measure time and space are being affected is because the rate of time flows and the space between objects are being affected. How else would you explain the discrepancies? What magical force is there that, for some reason, makes particles decay at different rates and atomic transitions happen differently? When we know for a fact that laws of physics are identical in all these inertial frames? You literally know nothing about physics, and are going "The physicists are wrong. I know better." as if physicists hadn't already thought of this explanation before you even existed. It didn't work, it was wrong, and so they abandoned it. All of these false explanation were ruled out by Einstein in 1905. It's so silly.

Jojo reference 🟢⚪️🌚

So if you lived on a earth 500x the size of the largest sun would you live longer but time for you would go by the same like on earth you live 80 years but on massive earth you live 800 years. You would run, walk, think at the same speed as earth?

How is time moving slower though? It’s like when I walk around a neighborhood block it takes me longer to walk around the neighborhood block than me just walking through it but I’m still moving the exact same speed. So time is still technically the same right? I get everything else just not the time part can somone please explain.

The time you observe right now is already "slowed", but in our perspective it's normal time. If we were to stay in a different planet with a higher gravity to earth, time will be slower compared to the time back on earth.

Except that time dilation causes gravity.

But if you timed yourself the speed of the clock wouldn’t go slower or faster

How can you possibly say that if you have not travelled in the speed of light? To add to this, it's not observable unless you're in a different planet which will show that time isn't constant. 1 second on earth will be different on other planets.

a good way to visualize worm holes is to think of two opposite corners of a flat paper get put together. this makes a somewhat raindrop shape of shorts where the concerns are connected but everything else is not. the issue lies that we think in 2D and our world and universe has like a lot more of those. 5D 7D blah blah blah. imagine you are animating on a computer, to make some thing look like it is heading towards you it would have to go either left or right ever so slightly, and the object would have to increase in size, now this increase is size when something gets closer doesn't mean the object is getting bigger. human "seeing" is limited to 2D so we see these fake realities, but as a 2D computer can tell if something is getting closer by the size changing we can visualize some funky stuff happening to something with a 3D view, where you can see in all directions in sort, we don't see a particle getting bigger rather it slows down when it moves. the object never slows down like the object in the computer never gets bigger, rather it travels in another plane that our brains cannot visualize because of our brain computer limitations. the math works tho, math can say all of this is right and we can see it work in math. same way you can bend a straight line into a circle shape this line can then intersect with another part of the universe, but to us this whole curve is stright, the same way is it to the creature where to go forever straight on a circle. another issue lies that we are made out of matter which interacts with space. two points of the universe can exist at the same time, but we would have to travel in the fourth dimension to get there, the fourth dimension being time, so warm holes are essentially time travel with a location. but we can time travel by stopping time as well, because if everything else stops, but you move, that's still time travel. what we see when someone travels through time is teleportation because they are no longer bound to time. The same way eight to the computers sees a ball getting bigger when it's really not. wormholes teleport you even though it's really not. we are stuck into D and we see everything happening in 2D. a really really good thought experiment to help you visualize this is a small explanation of the 5D plain, which the theory states these curvature's are smaller than the actual atom. you have a bead that is on a string, this bead has to go through all of the string at a constant speed. so if the speed is traveling on the string, and it comes to the knot, that is too small for us to see, we see the atoms, stop spin, and then go, we call this a time skip, the atom never stopped it just went in other directions that can not be map on a 2D plain so our brains can not comprehend what exactly is going on. Just because we see an atom stop that doesn't mean it stops in time, math can you help us explain that is traveling through curved space-time.

Due to relativity the other side of the wormhole can theoretically take you further back in time this has nothing to do with the shape and everything to do with the wormhole connecting to seperate points in spacetime… those points do not have to be synced relative to the observers time. If end point B is 5000 years in the past and you go from endpoint A to B you’d be 5000 years in the past however going back,, you’d end up right where you started 5000 years in the past in a different galaxy is largely irrelevent to us.
