[@new-knowledge8040]

They always make it sound so bizarre and complicated. In truth, all objects travel at "c", and they all do so in the 4 dimensional environment that is known as Space-Time. If you examine the outcome of this phenomena, you will independently discover Special Relativity(SR). You also independently derive all of the SR equations.

[@ryderdrew]

Nikhil Manhas or you're just shitty at explaining things.

[@gsanewphysics8902]

Yes, Einstein himself can't explain well enough about his proving method via eclipse, means Einstein doesn't understand it (basic astronomy) well. Einstein proving method via eclipse isn't scientific and deeply wrong.

[@new-knowledge8040]

Imagine a bunch of particles moving at the speed of light within the 3 spatial dimensions of a transparent box. Now imagine we add one more dimension to the box such that its new shape is a 4 dimensional Space-Time shape. It now extends across 3 spatial dimensions, and 1 time dimension. The particles inside it are still on the move at the speed of light, but now they may move across the added dimension as well. The greater a degree a particles motion is across time, the lesser it is in motion across space. Since some percentage of the particles motion is across time, an external observer would observe that these particles are moving at less than the speed of light, even though their magnitude of motion has not changed. Anyhow, if you examine the concept of all objects traveling at "c" within 4D Space-Time, the outcome of the analysis is an independent discovery of Special Relativity and all of its mathematical equations.

[@new-knowledge8040]

If you reverse engineer SR, you find that all objects move at "c" within Space-Time. See " The Elegant Universe " PDF - By Brian Greene, Pages 26 & 27. Even if you have no physics education, and you just use your head to analyze "motion", you will eventually discover SR and all of its mathematical equations independently.

[@SeventeenSphinx]

bugman bugman I struggled with it for a long time also. This is the way I finally understood it...pretend (I know this isn’t real but just to help you understand) that the speed of light was 1,000 miles per hour and nothing in the universe can go faster than that. Now imagine you are running 10 miles per hour with a flashlight in your hand...and then you turn on the flashlight and point forward. That would mean the light would be traveling straight ahead at 1,010 miles an hour right? (The speed of light plus the extra speed you are adding by running). But we know now that is impossible...light is a constant so it cannot go faster than 1,000 miles per hour (in this example). In order for it to remain at 1,000 miles per hour something else has to slow down and that is time. Since light can’t slow down or speed up. So we are the ones affected. Think about the x men movie where quicksilver is beating up those guards I. The pentagon....he is moving extremely quick and time has to slow down around him.

[@SeventeenSphinx]

bugman bugman well keep in mind well that Example isn’t perfect but keep in mind that’s why it applies specifically to things moving at or near the speed of light, as you get closer to that speed everything else seems to completely stop. There are lifeless planets in the universe that are traveling hundreds of thousands of miles per hour faster than us which is why living there for a year would be like living 30 years here.

Since the universe is expanding and evolving, 1st theory is not 100% correct automatically. Big Bang theory says that the current age of universe is 11-20 billion years. But according to new observations, i.e. clusters of galaxies, super-clusters, Great Wall (Tully's complexes), it is quite evident that our universe is much much older than that. Lots of cosmologist believe that big-bang theory is not correct although it is most widely accepted. In short, modern man is not aware of forces and science which are needed to expain the creation of universe. Lets look at vedic science and what it says. Right now I am quoting only what it says: a. Total age of universe is 311.04 trillion years (human years). b. Current age is around 155.521972944 trillion years. How it is calculated: -> There are 4 ages on earth which keeps circulating: Satya Yuga - 1.728 million years Treta Yuga - 1.296 million years Dwapara Yuga - 0.864 million years Kali Yuga - 0.432 million years Total: 4.32 million human years. -> This yuga cycle is called maha (in english, it means great/big) or divya (divine) yuga. One thousand such cycles forms one day of Brahma (a demigod in hindu religion which governs the universe). So one day of Brahma is 4.32 million * 1000 = 4.32 billion human years. Each such day of Brahma is called a "kalpa". His night also constitutes 4.32 billion human years. During his day, life exists in universe. In nighttime, no form of life exists. So one complete day and night has 8.64 billion human years. -> Age of Brahma is 100 years. Each year of Brahma has 360 days and same number of nights. Thus, total age of Brahma is 360 * 100 * 8.64 billion = 311,040 billion human years. i.e. 311.04 trillion years. This period is called "maha kalpa". -> The life span of the universe is one "maha kalpa". i.e. 311.04 trillion human years. This time span is also the duration of one breath of "Vishnu" (the ultimate god in hindu religion). When he exhales, thousands of universes emerges and one "Brahma" is born in each universe. When "Vishnu" inhales, all universes get sucked and Brahma dies. -> This cycle is non-ending and eternal. Thats why "Vishnu" is considered eternal in Vedic Science (or religion). How much old is our universe: -> Note that the period of Satya Yuga is 0.4x, Treta Yuga is 0.3x, Dwapara Yuga is 0.2x and Kali Yuga is 0.1x where x is the time-span of one maha-yuga cycle. I will use 'x' as 1 maha-yuga cycle subsequently. -> In 1 day of Brahma, there are 14 "manvantara". Each "manvantara" is divided into 71 "maha-yuga" cycles. So total make 14*71 = 994x (mahayuga cycles). -> Remaining cycles (1 day of Brahma contains 1000 maha-yuga cycles) are used to fill gaps between manvantara. Before and after each manvantara (called as "sandhya" and "sandhyamsa" respectively), there is a junction of 1.728 million (age of Satya Yuga, or 0.4x) human years. Total number of junctions are 15 (since there are 14 manvantaras). So total gap period is = 0.4 * 15 = 6x. Hence total makes 1000 maha-yuga cycles or 1 brahma day. -> According to the Vedic texts, current age of Brahma is 50 Brahma years and 1 brahma day (we are in the 1st day of 2nd half of brahma)and we are in the seventh "manvantara", in the 28th turnover of its 71 yuga cycles. In this cycle, we are in the start Kali Yuga. Age of kali yuga is not known perfectly but it is around 5000-10000 years. For calculation, lets assume 8000 human years. -> So current age of our universe (in terms of maha-yuga cycles) = (50 * 720 * 1000) -- 50 years * (360 days + 360 nights) * total no. of cycles in one day/night + (6 * 71) -- 6 manvantara each of 71 maha-yuga cycle + (7 * 0.4) -- 7 junctions or gaps for 6 manvantara + (27 * 1) -- we are in 28th cycle of 71 + (0.4+0.3+0.2) -- In this cycle, we are in Kali Yuga. Satya Yuga, Treat Yuga and Dwapara yuga are 0.4x, 0.3x and 0.2x respectively. + around 8000 human years -- very small, so ignoring it. Thus total age = (36,000,000 + 456.7)x = 36,000,456.7 * 4.32 million = 155,521,972.944 million years = 155.521972944 trillion human years. Now add the age of kaliyuga. i.e. around 8000 human years. One we calculate the exact age of kaliyuga, we can know the exact age of universe. How ancient Indians (or Vedic people, more precisely) come up with these numbers, I dont have a clue.

at 3:51 It would be helpful for listeners if you had emphasized, exactly why "something has to be given-away" for speed of light in both clocks to remain same. I mean it would have been easier to understand if you had explained why the space-ship clock's light had to travel extra-distance.

[@bigmusicboom1620]

Simrandeep Singh if it travel slow the distance will be less and if you travel faster than that light speed,,the distance will be large

[@Sehyo]

The reason it has to travel an extra distance is because it has to travel the combination of two vectors. Vector A: Up/Down inside the light clock, and Vector B: The velocity of the spaceship. If the spaceship is stationary, Vector A + Vector B is equal to Vector A alone. But if the spaceship is moving, Vector A + Vector B != Vector A, thus there is a greater distance to be travelled. Light speed is a constant, so it is impossible for light to traverse the new combined vector in the same amount of time as it would traverse Vector A. Therefore, this is proof of time slowing down for moving objects.

[@-danR]

@@Sehyo There's no reason why a light pulse that is traveling orthogonal to the direction of space-ship/apparatus travel should mysteriously have added to it a lateral velocity component equal to that of the reference-frame of the apparatus generating and reflecting it. It's not going have an apparent or real or pseudo-real diagonal path at all. Going at sufficient velocity, the spaceship's photon should start missing the mirror(s) altogether, and that's what an external observer is going to see. That's perfectly _obvious._ What isn't obvious to Einstein in the ship is why the light starts missing the mirrors. His reference-frame is stationary. His clock is stationary; the light pulse should be bouncing up and down quite normally. I'm underscoring a problem with the classic gendankenexperiment that's seldom or never addressed in these simplistic videos.

[@nohaxjustxmod-sfs3984]

Hey, even though both are different, gravitational time dilation and velocitous time dilation are kind of the same when you think about it. Since, energy is equivalent to mass, the more kinetic energy you put in matter, the more mass it will have. This effect grows exponentially as the object reaches closer to the speed of light, to the point that it would require an infinite amount of energy for said object to reach this speed or faster. But, the more mass an object has, the stronger it’s effect on spacetime’s curvature. In other words, it would have gravity. A sub-luminous object would be dominated by energy mass equivalence, and therefore the effect of time dilation for velocity actually comes from the gravitational influence, which in turn is from mass that said sub-luminous object has which comes from it’s kinetic energy. Correct me if I’m wrong, I made this connection myself and I’m no physicist.

[@KibyNykraft]

Of all the relativists' superb understanding and work, the idea of the space "curvature" is probably the dumbest. All of science in astronomy and advanced engineering of the industrial age is based on the foundation of space as literally empty (a background). Apart from its matter and potentially dark particles or antiphotons etc. If it can be curved it is not space, it is a fabric or liquid, meaning it would have to be filled with molecules like in an atmosphere or gelly. That is just unrealistic. There probably must be a better way to describe gravity

[@shaileshkarmukil163]

Since the universe is expanding and evolving, 1st theory is not 100% correct automatically. Big Bang theory says that the current age of universe is 11-20 billion years. But according to new observations, i.e. clusters of galaxies, super-clusters, Great Wall (Tully's complexes), it is quite evident that our universe is much much older than that. Lots of cosmologist believe that big-bang theory is not correct although it is most widely accepted. In short, modern man is not aware of forces and science which are needed to expain the creation of universe. Lets look at vedic science and what it says. Right now I am quoting only what it says: a. Total age of universe is 311.04 trillion years (human years). b. Current age is around 155.521972944 trillion years. How it is calculated: -> There are 4 ages on earth which keeps circulating: Satya Yuga - 1.728 million years Treta Yuga - 1.296 million years Dwapara Yuga - 0.864 million years Kali Yuga - 0.432 million years Total: 4.32 million human years. -> This yuga cycle is called maha (in english, it means great/big) or divya (divine) yuga. One thousand such cycles forms one day of Brahma (a demigod in hindu religion which governs the universe). So one day of Brahma is 4.32 million * 1000 = 4.32 billion human years. Each such day of Brahma is called a "kalpa". His night also constitutes 4.32 billion human years. During his day, life exists in universe. In nighttime, no form of life exists. So one complete day and night has 8.64 billion human years. -> Age of Brahma is 100 years. Each year of Brahma has 360 days and same number of nights. Thus, total age of Brahma is 360 * 100 * 8.64 billion = 311,040 billion human years. i.e. 311.04 trillion years. This period is called "maha kalpa". -> The life span of the universe is one "maha kalpa". i.e. 311.04 trillion human years. This time span is also the duration of one breath of "Vishnu" (the ultimate god in hindu religion). When he exhales, thousands of universes emerges and one "Brahma" is born in each universe. When "Vishnu" inhales, all universes get sucked and Brahma dies. -> This cycle is non-ending and eternal. Thats why "Vishnu" is considered eternal in Vedic Science (or religion). How much old is our universe: -> Note that the period of Satya Yuga is 0.4x, Treta Yuga is 0.3x, Dwapara Yuga is 0.2x and Kali Yuga is 0.1x where x is the time-span of one maha-yuga cycle. I will use 'x' as 1 maha-yuga cycle subsequently. -> In 1 day of Brahma, there are 14 "manvantara". Each "manvantara" is divided into 71 "maha-yuga" cycles. So total make 14*71 = 994x (mahayuga cycles). -> Remaining cycles (1 day of Brahma contains 1000 maha-yuga cycles) are used to fill gaps between manvantara. Before and after each manvantara (called as "sandhya" and "sandhyamsa" respectively), there is a junction of 1.728 million (age of Satya Yuga, or 0.4x) human years. Total number of junctions are 15 (since there are 14 manvantaras). So total gap period is = 0.4 * 15 = 6x. Hence total makes 1000 maha-yuga cycles or 1 brahma day. -> According to the Vedic texts, current age of Brahma is 50 Brahma years and 1 brahma day (we are in the 1st day of 2nd half of brahma)and we are in the seventh "manvantara", in the 28th turnover of its 71 yuga cycles. In this cycle, we are in the start Kali Yuga. Age of kali yuga is not known perfectly but it is around 5000-10000 years. For calculation, lets assume 8000 human years. -> So current age of our universe (in terms of maha-yuga cycles) = (50 * 720 * 1000) -- 50 years * (360 days + 360 nights) * total no. of cycles in one day/night + (6 * 71) -- 6 manvantara each of 71 maha-yuga cycle + (7 * 0.4) -- 7 junctions or gaps for 6 manvantara + (27 * 1) -- we are in 28th cycle of 71 + (0.4+0.3+0.2) -- In this cycle, we are in Kali Yuga. Satya Yuga, Treat Yuga and Dwapara yuga are 0.4x, 0.3x and 0.2x respectively. + around 8000 human years -- very small, so ignoring it. Thus total age = (36,000,000 + 456.7)x = 36,000,456.7 * 4.32 million = 155,521,972.944 million years = 155.521972944 trillion human years. Now add the age of kaliyuga. i.e. around 8000 human years. One we calculate the exact age of kaliyuga, we can know the exact age of universe. How ancient Indians (or Vedic people, more precisely) come up with these numbers, I dont have a clue.

You must differentiate between proper time and improper time which are in two different frames of reference. In the first the same observer is present for both events. In the latter case different observers observe the two events in their common frame of reference. The point underlying the theory of relativity is that light 'motion' can be measured only with respect to an observer not with respect to a medium.

(I'm no expert) I had proposed this to my physics teacher; I think that time (as we know it) can be simply understood as a measurement of change. After all, this is what we measure to find time (usually through oscillations), whether it be the oscillation of a pendulum in a grandfather clock, or an atom in a quantum clock. Thinking this, we are exposed to the idea that with topics of relativity and time dilation, what we are really talking about is how forces as in gravity and acceleration etc, can alter these changes that we measure, something that may affect all particles in a certain way (hence why one may stay young while others elsewhere grow old). Another concept takes a step back to concepts of an absolute time or a universal quantum. Is this possible, although considered negated by theories of relativity, and if so is there something actually set or constant in the universe not affected by such forces? Through the same relativity it may seem to speed up or slow down in some manner to us. It's amazing to think about actually. The more we know, the more we don't, an endless cycle of questions.

I learnt more in this demonstration video about time, than in ANY OTHER physics class, or video. I have been wondering what time is, or could be proven for 30 years. But it is already proven now thanks to physocs. Thank you for FINALLY, explaining it to me. Time is basically the gaps in between light. Light being constant. And, if one could travel just 1 km faster, time trqvel would be possible, bit only forwards, prpbably why we dont see anyone from the past. I guarantee you can travel forward, but it would also be relative. And, now i know even more about why Einstein says time is relative. One thing id like to propose for out the box thinkers out there is the following. When we dream, time seems to cease existing, yet, it doesnt. We go to sleep, it feels like mere moments have passed, but, iits been hours. This phenomonenon is making even more sense now though. My theory has been and is merely a phenomenon of being human.i used to believe, dreams were a form of spiritual time travel. But i think thats just the way our brain doesnt percieve anything while sleeping much less time. But i was beginning to believe we were able to change time somehow in our sleep. And also had some time travel theories, but i know now. U can go forwards, not backwards! Thank you again

[@aashishgrover5603]

Time slows down for Einstein and his spaceship. For what would have been a day aboard the imaginary spaceship, would be years on Earth. Remember speed = distance/time. For speed to be increasing and reaching " c " (speed of light) the time needs to become a smaller quantity ( speed is inversely proportional to time ).Therefore for Einstein at speed of light; time slows down. For imagination :- If Einstein was doing an ultra slow robot dance aboard his spacecraft at speed of light and you were viewing him from outside in space...it would appear like a full on Bruce Lee Karate Chop. For Einstein it would still be a slow dance, But for you it would be like "Bruce Lee's Karate chop". ;-)

+soslothful Yes the biological clock does slow down...for Einstein it may appear that he had been travelling for just a day....but that would have been years in earth... It's just a matter of frame of reference...Our perception of time is based upon earth's revolution (day) and it's rotation around the sun (year)... But for space travellers it's not so... The movie Interstellar is based on this concept only... Remeber how the hero's daughter is older than him at the last scene... After the hero returns from the space travel....

That's exactly the point. As you said, it's not possible for d/t to be equal to D/t. However, we know they're equal because they both are speed of light, which we know is constant. This is only possible if the second t is bigger. That means it takes a longer time for D.

@@prasadjonnalagadda4021 I know this sounds obvious, but never forget to consider the relativity aspect here. To put it simply (and perhaps I'm oversimplifying a bit), we are considering the measuring of time for a specific event, as done by a stationary observer relative to a moving observer. If we put numbers to it, just for illustration, the moving observer may measure d/t = c while the stationary observer measures D/T = c for the same event. D > d, therefore T > t; so, an event that takes e.g. t = 1s in the moving observer's frame of reference may take T = 2s in the stationary observer's frame of reference; therefore, 1s for the moving observer is equivalent to 2s for the stationary observer, so time has slowed down for the moving observer (he/she measures less time elapsed than the stationary observer for the same event). But that is only part of it; the really mind boggling aspect of relativity is that from each observer's point of view, he/she is the one that is stationary while the other observer is the one that is moving. So each observer considers the time of the other one to be slowing down, and relativity states that both of them are correct since there is no such thing as an absolute frame of reference. For this to work out mathematically and physically, not only time dilation, but also length contraction need to be taken into account - a fact that unfortunately is often overlooked by many videos that attempt to explain special relativity.

[@greggorsag9787]

This is a really good, simple explanation. One of the clearest I’ve seen. However, it has always seemed to me that what is relative is *the measurement of time*. Or alternatively, that physical change is altered as speed increases. Putting this another way, I have never been able to get over the issue of using time in equations and theories without being able to say what it IS.

[@REALdavidmiscarriage]

but this doesn't mean time doesnt pass right? einstein just doesn't see anything change bc the photons can't go faster than light and can't reach his eyes, but this doesn't mean that time actually stops passing for him.

[@jaskaransethy]

it means precisely that time is slower for him. it's passing, but not at the same rate

[@maxastna5939]

I still don't understand how speed influences time

[@elguignole]

I just did the math with simple numbers, maybe it can help. Lets say c = d/t, and that d=1m and t=1s, then c=1m/s. Now you (not on the space ship) watch the clock attached to the space ship and the ligth appear to travel longer lenght in same laps of time (a somewhat diagonal), so you assume a longer distance. so you come to the math c = 2m/s. But you just altered 'c' and a theorem state that you can't, so there is only one variable you can still change to make this work, wich is 't'. The final formula is 1m/s=2m/2s. So, the light kept moving at the same speed, but to achieve a greater distance, time was slown.

Special relativity says that motion is always relative. Imagine a baseball floating alone in empty space. How do you know if it's moving or not? You can't. But if you put a basketball in space with the baseball, you could see whether the baseball was getting closer to the basketball or further away from it. Then you could see if the baseball was moving. That's why it's called ''relativity.'' The motion of one thing is always relative to the motion of everything else.

Time is not a physical quantity, Time is just a concept. Again as mentioned in the video, Time is relative and differs based on the frame of reference, meaning While Einstein is traveling in a spaceship with the clock, the time has to slow down so that the speed of light can remain constant because it travels more distance for the stationary frame of reference however for Einstein (who is inside the spaceship) Time has not slowed down at all. Going by this, While the age (as a measure of time) of Einstein and you might differ after he traveled through space, but as shown in the video, he would not look young and you would not look old because his time slowed down because time is a concept and just a measurement and your cells in the body would still remain the same. I am trying to find out if there are researches that can explain traveling faster would have an impact on our cells in the body making them live longer.
