Before I knew what an Einstein theory was I’m sitting in middle/high school, day dreaming about stuff, and had imagined what it would look like to move at the speed of light. I imagined time standing still, because in my thought I would be covering more distance in what would appear to be no time at all. And yet, if I left to someplace on earth and came back at that speed it would look like I had never left to everyone else. Of course, soon as I got deep into thought about this I’d be snapped back to reality when the teacher yelled, “HEY! PAY ATTENTION!” And so there you have it, the story of why I’m not Einstein. Now I work in a warehouse using my gifts to fulfill amazon orders.
Bro if you travelled at the speed of light and came back to earth. Everyone would be dead already. The time stops for you, but continues for everybody else
@@Dan-yn4xh he meant if he circumvented Earth at the speed of light. If you went to Andromeda, everyone would indeed die, but not for a tiny moment it takes to circumvent it.
The same for me. Although on the surface level I do understand what this theory wants to convey. But it's hard to imagine it or kind of feel it. I have watched a ton of other videos about this some made a little sense others went right above my head. There's still so much to comprehend but this short has kind of clicked the concept a little. I guess this is how we learn😅
@@snowwhite2038I know exactly what you mean about feeling it. That’s my biggest struggle. But just recently I had an amazing moment looking at Jupiter and i had an app that showed me the current orbit of the planets and for the first time the “feeling” of being on this floating rock in space truly clicked. Like I truly understand my place in space and time now
It’s what you see. A clock’s second hand will always tick. Unless the battery goes out. But yes, you’re you’re also moving faster through spacetime. 😮😱
Time is dilating. Just walking dilates time. As you move through space, your distance (space) contracts. You divide distace over velocity . You will notice that distance contracts and the faster you do it. You perceive time in your frame normal but others see you differently. Both age the same. Gravity is the same with time but it curves (expands) space. So the less movement through space results in slower time. Time is just divided movement through space. We need to remember how we think of time when measuring. Normally moments passing is called time too. But that’s not how we measure it. Looking in the right area is key to understanding time dilation. Let me know if ya have any questions.
Time doesn't slow down - light just takes longer to reach your eyes to update what's happening back at the clock tower, until it never reaches your eyes
So time doesn't pass slower, you just don't see things move because the light can't reach your eyes? I cannot totally understand this, the same with time dilation caused by gravity
I've been in a rabbit hole for a month on general relativity. This video puts me a step back in trying to understand. While time does in fact slow down, this video in my opinion tells what you are saying. Also note that there are two things having impact on your time relative to others: 1 is gravity, and 2 is you moving. Both slowing time more the stronger the force or faster you go.
Time does pass slower. It’s due to the fact that the speed of light has to be the same in all reference frames. If you travel 99% the speed of light and shine a torch out of your vehicle facing the direction you came from, the light shouldn’t travel as fast but since it has to, time literally slows down to accommodate this.
@@expampr depends on how you think of it. But time exists to differentiate the positions of objects/events between 'intervals'. To me, time exists in some capacity at least.
If you had a clock following you in your face I feel the hands would move the same speed the only thing that changed is how far you got in such a short time span
@@davidridgeway5793 the idea is to imagine a clock in front of you as you need a clock in your frame of reference to measure time. If you speed up to max speed nothing in your frame can move faster and thus a measure of a second can’t be taken. since that’s movement in space is maxed out.
Hello, here is the best thought experiment to bring clarity to the subject - First off, Einstein thought the math regarding this did not accurately describe physical reality. It's not his math, he hired someone for that. His math is represented in a dilation/time dilation graph, X amount of velocity = X amount of dilation/gamma. If a spaceship travels at a constant 1g acceleration rate, it would achieve about 95% light speed in 1 year. No matter how fast the ship goes everything would be normal from its perspective, hence the term "invariant". We are all traveling at the speed of light relative to some potential vantage point. Mass dilation does not mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Hence the term "mass becomes infinite at the speed of light." When the ship reaches 50% light speed, as viewed from an Earthbound observer with a magically powerful telescope, it would appear normal because as the graph shows, nothing has changed at that point. When the ship reaches 75% light speed it would appear fuzzy because as the graph shows relativistic effects would be noticeable at that point. When the ship reaches 99% light speed it would not be visible because every aspect of its existence would be spread throughout spacetime relative to an Earthbound observer. Mass dilation occurs wherever there is an astronomical quantity of mass. Einstein wrote about this, this means that Relativity forbids astronomical concentrations of mass. The mass in our galactic center is dilated. In other words it's not just there, it's everywhere.
so is 13 billion year old universe the same number for the other civilizations if there are in the universe or is it more or less according to their space time ?
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
Im still quite trying to understand time dilation myself, but the reason that we’re finding out that the universe is 13 billion years old is because light from the big bang has taken 13 billion years to reach us
I too have the same question though..so 13 billion year old universe is the same number for the other civilizations if there are in the universe or is more or less according to their space time ?
@@shaun5657we all live on the fabric of the universe whilst woven into it. Like a little bump sticking out. Like lint lol. If you move faster, you separate your reality you was living in. Rest of earth will stay in their place carry on being woven like normal. I believe you can only go to the future, never the past. Hence black holes. 😮😱
Time didnt slow down for Einstein. Its just that everything we see with our eyes comes from light, and when the clock moves, the visual information of that clock moving, moves at lightspeed away from the tower. And now because Einstein is also moving at this speed, new information from the clock cannot reach him, therefore appearing time to stand still behind him. If Einstein were to move towards the same clock, time would move faster on the clock.
Light is the same no matter who's viewing it, so to keep that a constant, spacetime needs to bend and swish so everyone measures the speed of light the same.
Actually u r saying purely truth, when u r travelling the speed of light the new wave of light can not reach your eye and that is why we see the clock stick on the we saw it, and though the watch inside is also travelling with him so he can see it moving
I’ve got a question Imagine a theoretical phone that can communicate and use FaceTime with anyone no matter the distance, now imagine 2 guys using that phone, they are FaceTiming each other, one guy is on earth and the other guy is orbiting a black hole in a distance that time dilation is very strong,what will the other guy on earth see?
Well as per my thought processing, due to the strong time dilation at the other guy's location in reference to guy on earth, the flow of time would be relatively much slower near the black hole as compared to the time on earth and the device signals themselves would take a lot of time (in terms of the time flow on earth) to get transmitted from the other guy's device (where time is dilated relative to earth) to the guy on earth & even when the signals reach, the guy on earth will perceive the other guy's motion/actions and other things he see on the FaceTime as relatively much slowed. Now, while the signals are transmitted from earth guy to black hole guy, they are faster transferred when around earth and are relatively slower when approaching black hole (measuring their speed/velocity qualitatively in terms of time flow on earth). Thus, the other guy also recieves signals from earth guy after vast amount of time but he sees the earth guy's motion/actions and other things on FaceTime to be relatively much faster.
I get that the clock tower appears frozen because the light can’t reach Einstein’s eyes, but I don’t get how moving close to the speed of light affects aging for example. Even though Einstein can’t see objects move that he’s traveling away from, how does that make his body age slower
@@MrMoose1347 No because he is moving at the speed of light. The faster you move through space the slower you move through time. At the speed of light there is no passage of time.
Take two clock, place them a light second far from each other. Sync them, and now move from one clock to another clock at speed of light, time has changed 😮
@@Kanpuriye mass and energy are equivalent. As they have their limits to motion in the field of spacetime. So when we measure a second at the surface of earth because of gravity it has its fixed rate. But we take the same clock to space we notice it counts quicker.

Without gravity I can go its rate outside the gravitational field. Next special relativity. A stationary clock measures a certain distance at a certain rate to equal a second. Force the clock to move and the distance and rate change. Both cause dilation when comparing clocks.
is this like if u run a 100m race and one of the racer is gonna go slow and one is gonna go fast and the slow racer wastes more time running which means time is faster for him but for the guy running fast, time went by slower for him or
@@kithnywrong. Astronauts undergo accelerated heart rates during lift-off while the onboard chronometer is slowing down. Explain that Einstein. The Breakthrough Starshot solar sail is bursting into frames once it reaches. 2c while it's twin on earth hasn't aged a day. Explain that Einstein. Oh. And you experiment that proves time-dilation. The synchronized clocks experiment performed by Hafele-Keating. They didn't even bother to record how much energy each clock used. Why is that important. Because Energy equals Time. E=mc where c is speed of light. Since speed is distance/time, Energy equals Time. When two clocks use the same amount of energy, they experience the same amount of run Time. Where is your time-dilation Einstein?
I don't get the logic of this, they measure time by the latency on how we see things or light/images reaches our eyes? If someone can move a speed of light, going away for million light years with an alarm clock for 20 mins, then go back. I would assume that he will just return to us afyer 40 mins lol. I dont think distance is related to time. Im so simpleminded.
Relativity is wrong. Time is time regardless of speed, it never stops, it never slows down, it doesnt matter how fast u go, has nothing to do with perspective, Its simple the only difference is that the lightspeed traveler will reach the distance a Lot Lot Lot faster than the normal speed traveler.
I see what this is saying, but the idea that time has stopped is not true. The only thing that is happening is the light reflecting off of that clock cannot catch you because you’re traveling at the same speed as it is. He would still age and exist in time
Time has stopped for the outside world from his reference frame. If he traveled for 1 light year at the speed of light then he wouldn't have aged at all, but people at rest relative to him would be 1 year older. The idea is completely true, as proven by numerous clock experiments.
@@LiberatedMind1 no. That’s a misunderstanding too. You don’t age differently because of speed. You appear to because the measure changes. Muons prove this.
It is true that time “stops” when going c. This is because you can’t get a measure of motion being faster than all motion. Time doesn’t actually stop but it does effect the measure depending on frame
@ No it’s not, you are the one misunderstanding. Physics texts books and Einstein himself clearly state that time dilates and runs at different relative rates. Clock experiments show a discrepancy after one experienced motion and the other did not. They experienced different amounts of time.
Just because it appears to slow down doesn’t mean that it does! I literally am so angered by this, it’s literally called a theory, it’s never been proven nor will it. If this were true then fighter jet pilots would die sooner than the average person due to time spent at such great speed, when actually they live longer than the average life span.
Theory is just explanation of the observed so yea it’s theory. Scientific theory at that. Because we test and observe for consistency. We got it. Theory isn’t wrong or right all the time either
At 186000 miles per second the clock tower could not even be seen to know if the hands stopped in time or not. Another impossible theory to waste your mind on. Only looked at time dilation to appease a neighbour that said it's "mind blowing" LOL it is, if you waste your thoughts on it.
Replace the clock tower with an atomic clock and the principle still applies. Satellites have to take time dilation into consideration just so our GPS’ on earth sync up
@@AdrianStoica-e5b What are you talking about? This is measurable. Your phone's clock literally has to account for this time dilation in order to stay accurate because the satellites it gets the information from are traveling faster, which makes them experience time differently.
@@OnlyBlix The slowing down physical processes... ,-clock is an mechanism too, etc.(because acceleration and gravity) does not mean that Real Time dilates.. Wrong conclusion and wrong logic.. Only subjective perception about time can change..,not real time !!!
So if you could travel faster then the speed of light, you could reverse time on earth? Assuming you had a telescope that could see trillions of miles away
No. If you can travel at the speed of light you can travel forward in time. So if you travel to a planet 5 light years away at the speed of light, you would arrive at the planet instantly like you had teleported but to the people watching from earth you took 5 years
Proof that Einstein didn't understand the math and math errors that he plagiarized from Lorentz. Time dilation turns out to simply be an artifact of the math errors in his time dilation derivation that he plagiarized from the Lorentz length contraction derivation. The substitutions may have worked for Lorentz in length contraction, when an object moves wrt the ether, but Einstein's time dilation equations are invalid for objects moving wrt to random objects other than a stationary ether medium.
You misunderstand the history and facts. He didn’t plagiarize. He had colleagues that helped refine his theory. The math proves time dilation like theory of relativity does. Also ether doesn’t exist as a medium he uses fields to describe his space
Nonsense - he is just a victim of a medium that isn't fast enough to keep him totally up to date! Today when we look at 'streamed' news report there is always a delay as the streaming catches up. It isn't that we the viewer have suddenly changed time with the transmission! Complete bull!
@@LiberatedMind1 No they don't. Clocks do not measure time, they are the way in which we define 'time'. Time is an invention of man. As such there can only be ONE time. You can't distort a concept. But THINK - what are clocks? You seem to trust clocks but they are simply a mechanism that goes round and round (as long as you power them) The hands move at a speed we define and point at numbers that we paint there - there is NOWHERE that 'time' is input to any design of clock - and there are at least 50. All a clock has to do is move - a burning candle with charcol marks on is a clock', a leaking bowl of water is a 'clock'. As time cannot be felt - how is it possible for time to affect or drive a clocks hands? No- the definition of time means that 12:45 here is 12:45 on any star you choose. Scientists get this wrong, in this experiment both (all) clocks should read the same time as time is a definition!
@@LiberatedMind1 Clocks move because of forces generated by the energy we put into them. Time does not exert a force - but you believe that time slows or speeds up a clock? How? What force does time exert on a clock? Man invented time - as it is a definition - you can't change it! You must think that clocks 'measure' time - they don't.
@ I don’t merely believe it’s been proven, by clock and light speed measuring experiments. Clocks move over time, not just force. You don’t need a force, if one clock experienced less time then it ticks less, that’s very simple. What do clocks measure then? A clock measures the rotation of the Earth on it’s axis, which takes time. We conceptualize time that doesn’t make it not real. If you don’t exist in time what do you exist in? How do you move if it takes time to move? Is an hour the same as a year?
@@LiberatedMind1 We live inside a clock. It has three readouts, days, months and years. For early man there was no concept of time but clearly day and night was something that man used to sleep and rise, seasons told when to plant and gather crops. BUT these events are the result of the physical rotation of the sun and earth, no 'time' is involved. As man got more intelligent it became useful to break the day up into parts for reasons of meeting and planning. A calendar is essentially a clock too. The sundial was clearly the first clock, but later more mechanical means gave finer resolution and the concept of 'time' evolved. Time simply being the current section of the day as determined BY THE CLOCK. No-one 'discovered' time. Clocks - like the sun/earth are simply rotating mechanisms that we use to DEFINE what 'time' it is. The early use of time was purely social and political. Later we used clocks independantly of the 'time of day' to study our world. We used stop watches to 'time' events and linked them mathmatically to give us velocity and acceleration measurements. BUT that is purely for mans use - no animal or inanimate object uses or requires 'time'. What bird needs to be somewhere at midday? What meteor needs to move at a specific speed? So ONLY man uses time and it is his concept alone. The corollary of this that there is NO actual past or future - we exist only in the 'NOW'. If you plan to meet tomorrow - you always actually meet 'now'. The difficulty people have is due to the fact that you will have used 'time' all your life and never had to think about it - we have past and future tenses in our language - massively useful for communication but we are only ever in the 'now'. When you read this are you in the 'now'? Yes. You will struggle to imagine being only in the 'now' but there really cannot be an actual past or future - for good reasons which is another subject. Think about how we 'play' with time, different time zones, stopwatches not linked to clocks, even some countries changing their time zones. Try not using any time rrealted words in the next day - you will find it impossible, we need it - but we invented it.
If I reference myself to the car I’m in, I’m not going fast but if I reference myself to the road I get a speed. Does that make sense how it’s what’s being referred to for measure of speed?

Still dont get it
I don't get the logic of this, they measure time by the latency on how we see things or light/images reaches our eyes? If someone can move a speed of light, going away for million light years with an alarm clock for 20 mins, then go back. I would assume that he will just return to us afyer 40 mins lol. I dont think distance is related to time. Im so simpleminded.
It’s just measured motion. Not latency or magic. But time does dilate
Relativity is wrong. Time is time regardless of speed, it never stops, it never slows down, it doesnt matter how fast u go, has nothing to do with perspective, Its simple the only difference is that the lightspeed traveler will reach the distance a Lot Lot Lot faster than the normal speed traveler.
time does slow down if you go fast. theres proofs too.
Your inability to comprehend doesn’t make it wrong
I still didn't understand
I get it now
If he travelled at 180,000 miles per second away from it, he wouldn’t be able to see the clock hands…
You missed the point like it went over your head at 180000mps 😂
I see what this is saying, but the idea that time has stopped is not true. The only thing that is happening is the light reflecting off of that clock cannot catch you because you’re traveling at the same speed as it is. He would still age and exist in time
Time has stopped for the outside world from his reference frame. If he traveled for 1 light year at the speed of light then he wouldn't have aged at all, but people at rest relative to him would be 1 year older. The idea is completely true, as proven by numerous clock experiments.
@@LiberatedMind1 no. That’s a misunderstanding too. You don’t age differently because of speed. You appear to because the measure changes. Muons prove this.
It is true that time “stops” when going c. This is because you can’t get a measure of motion being faster than all motion. Time doesn’t actually stop but it does effect the measure depending on frame
@ What do you think “time actually” is? Time actually stopped in the light speed frame.
@ No it’s not, you are the one misunderstanding. Physics texts books and Einstein himself clearly state that time dilates and runs at different relative rates. Clock experiments show a discrepancy after one experienced motion and the other did not. They experienced different amounts of time.
Just because it appears to slow down doesn’t mean that it does! I literally am so angered by this, it’s literally called a theory, it’s never been proven nor will it. If this were true then fighter jet pilots would die sooner than the average person due to time spent at such great speed, when actually they live longer than the average life span.
It’s true but you won’t age any different. Time does slow when accelerating. It’s been proven quite consistently
Theory is just explanation of the observed so yea it’s theory. Scientific theory at that. Because we test and observe for consistency. We got it. Theory isn’t wrong or right all the time either
At 186000 miles per second the clock tower could not even be seen to know if the hands stopped in time or not. Another impossible theory to waste your mind on. Only looked at time dilation to appease a neighbour that said it's "mind blowing" LOL it is, if you waste your thoughts on it.
Replace the clock tower with an atomic clock and the principle still applies. Satellites have to take time dilation into consideration just so our GPS’ on earth sync up
yep because the speed of light it's faster than the rotation earth on it's axis, and that clock tower isn't showing what the real time
I will mever believe this theory 😂
You don’t believe you move relative speed to others?
@@MrMoose1347 I do, I just don't believe it had any relation to time
@@armywhammer-dc9qk time is measured motion. So you believe it you just don’t know it.
@@MrMoose1347 that much is quite obvious
Its not time travel. Your just moving with the light waves
Pure illusion...
It's not real...😅
How so?
@@Jhelil Real time doesn't dilate..
Is Einstein sci-fi thinking...
@@AdrianStoica-e5b What are you talking about? This is measurable. Your phone's clock literally has to account for this time dilation in order to stay accurate because the satellites it gets the information from are traveling faster, which makes them experience time differently.
@@OnlyBlix The slowing down physical processes... ,-clock is an mechanism too, etc.(because acceleration and gravity) does not mean that Real Time dilates..
Wrong conclusion and wrong logic..
Only subjective perception about time can change..,not real time !!!
@@AdrianStoica-e5b that’s pure opinion and not fact. Time is real
So if you could travel faster then the speed of light, you could reverse time on earth? Assuming you had a telescope that could see trillions of miles away
@@StayBlessedTV no
No. If you can travel at the speed of light you can travel forward in time. So if you travel to a planet 5 light years away at the speed of light, you would arrive at the planet instantly like you had teleported but to the people watching from earth you took 5 years
So Einstein forgot the newton's first law of motion in his observation, that the clock doesn't move bocause of the external pressure 😂😂😂😂😂
Proof that Einstein didn't understand the math and math errors that he plagiarized from Lorentz.
Time dilation turns out to simply be an artifact of the math errors in his time dilation derivation that he plagiarized from the Lorentz length contraction derivation.
The substitutions may have worked for Lorentz in length contraction, when an object moves wrt the ether, but Einstein's time dilation equations are invalid for objects moving wrt to random objects other than a stationary ether medium.
You misunderstand the history and facts. He didn’t plagiarize. He had colleagues that helped refine his theory. The math proves time dilation like theory of relativity does. Also ether doesn’t exist as a medium he uses fields to describe his space
Nonsense - he is just a victim of a medium that isn't fast enough to keep him totally up to date! Today when we look at 'streamed' news report there is always a delay as the streaming catches up. It isn't that we the viewer have suddenly changed time with the transmission! Complete bull!
Clock experiments prove this happens, sorry buddy.
@@LiberatedMind1 No they don't. Clocks do not measure time, they are the way in which we define 'time'. Time is an invention of man. As such there can only be ONE time. You can't distort a concept. But THINK - what are clocks? You seem to trust clocks but they are simply a mechanism that goes round and round (as long as you power them) The hands move at a speed we define and point at numbers that we paint there - there is NOWHERE that 'time' is input to any design of clock - and there are at least 50. All a clock has to do is move - a burning candle with charcol marks on is a clock', a leaking bowl of water is a 'clock'. As time cannot be felt - how is it possible for time to affect or drive a clocks hands? No- the definition of time means that 12:45 here is 12:45 on any star you choose. Scientists get this wrong, in this experiment both (all) clocks should read the same time as time is a definition!
@@LiberatedMind1 Clocks move because of forces generated by the energy we put into them. Time does not exert a force - but you believe that time slows or speeds up a clock? How? What force does time exert on a clock? Man invented time - as it is a definition - you can't change it! You must think that clocks 'measure' time - they don't.
@ I don’t merely believe it’s been proven, by clock and light speed measuring experiments. Clocks move over time, not just force. You don’t need a force, if one clock experienced less time then it ticks less, that’s very simple. What do clocks measure then? A clock measures the rotation of the Earth on it’s axis, which takes time. We conceptualize time that doesn’t make it not real. If you don’t exist in time what do you exist in? How do you move if it takes time to move? Is an hour the same as a year?
@@LiberatedMind1 We live inside a clock. It has three readouts, days, months and years. For early man there was no concept of time but clearly day and night was something that man used to sleep and rise, seasons told when to plant and gather crops. BUT these events are the result of the physical rotation of the sun and earth, no 'time' is involved. As man got more intelligent it became useful to break the day up into parts for reasons of meeting and planning. A calendar is essentially a clock too. The sundial was clearly the first clock, but later more mechanical means gave finer resolution and the concept of 'time' evolved. Time simply being the current section of the day as determined BY THE CLOCK. No-one 'discovered' time. Clocks - like the sun/earth are simply rotating mechanisms that we use to DEFINE what 'time' it is. The early use of time was purely social and political. Later we used clocks independantly of the 'time of day' to study our world. We used stop watches to 'time' events and linked them mathmatically to give us velocity and acceleration measurements. BUT that is purely for mans use - no animal or inanimate object uses or requires 'time'. What bird needs to be somewhere at midday? What meteor needs to move at a specific speed? So ONLY man uses time and it is his concept alone. The corollary of this that there is NO actual past or future - we exist only in the 'NOW'. If you plan to meet tomorrow - you always actually meet 'now'. The difficulty people have is due to the fact that you will have used 'time' all your life and never had to think about it - we have past and future tenses in our language - massively useful for communication but we are only ever in the 'now'. When you read this are you in the 'now'? Yes. You will struggle to imagine being only in the 'now' but there really cannot be an actual past or future - for good reasons which is another subject. Think about how we 'play' with time, different time zones, stopwatches not linked to clocks, even some countries changing their time zones. Try not using any time rrealted words in the next day - you will find it impossible, we need it - but we invented it.
Time dialation is not real
It is and experiments have proved it
Deny it all you want
Clock experiments prove this happens, sorry buddy.
I just dont get it. Why is he seeing time freeze because he is just travelling on the same time regardless of the distance 🥱
If I reference myself to the car I’m in, I’m not going fast but if I reference myself to the road I get a speed. Does that make sense how it’s what’s being referred to for measure of speed?
This dude just likes to listen to himself talk.😂😂😂😂😂😂😂😂😂😂
