We will find out how do we know the time dilation is due to the general theory of relativity (simulated gravity) and NOT due to the special theory of relativity (going really fast).

man i was watching your videos for the past 1 year and i am vert grateful to you.

Time dilation is just one aspect of dilation (sometimes called gamma or y) it's not just time that gets dilated. Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote -

GPS satellites move at "only" 4 km/s, but the extreme timing demand means that the equipment must use relativistic calculation

Thank you 👍

Hi professor M. V. Biezen. Actually, acceleration does not contribute anything to time dilation but all the time dilation effect is due to velocity. This is shown repeated in circular particle accelerators. There is an article on this "Some Recent Experimental Tests of the "Clock Paradox" C. W. Sherwin. Phys. Rev. 120, 17 - Published 1 October 1960. I have the article however I could not find your email.

It would be interesting to know the velocity if you set the radius of the rotating disc to the same as the Schwartz radius of the black hole

Professor,

Thanks. For these wonderful lessons❤❤❤❤❤❤❤❤

Schwarzchild! Woot woot!

Professor if it is true that in 13k years the summer will be winter is the tropical year like totally wrong. Why aren’t we using sidereal? The vernal equinox in the tropical year wouldn’t even be the real vernal equinox. The Vedic year would be the real vernal equinox

Professor what is the current Ayanamsa that is closest to the stars?

[@zakirhussain-js9ku]

Due to gravitational time dilation time in a satellite runs faster than time on earth. Likewise time at event horizon should run faster than inside a BH. But time at event horizon is already zero. Do gravity & speed slow motion of clock or motion of time?

[@schifoso]

So kind of like satellites orbiting the earth? It's their acceleration and not their speed that causes their clocks to run at a different speed than those in the surface of the earth?
