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).
Next video in this series can be seen at:

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

[@MichelvanBiezen]

Glad you are enjoying the videos.

​@@MichelvanBiezenWHAT E=MC2 FUNDAMENTALLY means is that gravity/acceleration involves what is balanced inertia. INDEED, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Consider TIME AND time dilation ON BALANCE. This CLEARLY proves what is the fourth dimension, AND this CLEARLY solves what is the coronal heating “problem”. I have proven why the rotation of WHAT IS THE MOON matches the revolution, AS I have proven why WHAT IS THE MOON will (and does) move away very, very, very slightly in relation to WHAT IS THE EARTH/ground !!!! By Frank Martin DiMeglio Gravity/acceleration involves what is balanced inertia, as WHAT IS E=MC2 is taken directly from F=ma; AS the rotation of WHAT IS THE MOON matches the revolution. This is CLEARLY consistent with the FOURTH dimension AND conservation of energy, AS the stars AND PLANETS are POINTS in the night sky. (INDEED, gravity AND ELECTROMAGNETISM are linked AND BALANCED opposites.) Consider what is THE EYE ON BALANCE. What is E=MC2 is consistent with TIME AND time dilation ON BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE); AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE; AS E=MC2 is taken directly from F=ma; AS the stars AND PLANETS are POINTS in the night sky ON BALANCE; AS c squared CLEARLY does represent a dimension of SPACE (ON BALANCE); AS the rotation of WHAT IS THE MOON matches the revolution. Great. MOREOVER, WHAT IS THE MOON will (and does) move away very, very, very slightly IN RELATION TO what is THE EARTH/ground. Great. I have FUNDAMENTALLY and truly explained the cosmological redshift AND WHAT IS THE FOURTH dimension. (Consider WHAT IS complete combustion AND WHAT IS E=MC2.) GREAT. Again, gravity/acceleration involves what is balanced inertia; AS WHAT IS E=MC2 is taken directly from F=ma; AS I have FUNDAMENTALLY and truly explained the motion of what is THE MOON; AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Great !!!! Again, consider TIME AND time dilation ON BALANCE. Perfect. Think. Again, I have CLEARLY proven WHAT IS the FOURTH dimension ON BALANCE. “Mass”/ENERGY is CLEARLY electromagnetic/gravitational ON/IN BALANCE. GREAT !!!! By Frank Martin DiMeglio

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 - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light" Singularities were popularized by television and movies beginning in the 1960's. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc. Dilation will occur wherever there is an astronomical quantity of mass including centers of very high mass stars and the overwhelming majority of galaxy centers. Mass that is dilated is smeared through spacetime relative to an outside observer. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. The mass at the center of our own galaxy must be dilated, in other words that mass is all around us. This is the explanation for galaxy rotation curves/dark matter. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has recently been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal

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

[@MichelvanBiezen]

Yes, time accuracy is key in GPS.

Pls upload 2 videos a day We need more

[@MichelvanBiezen]

Unfortunately, we don't have the time to make them that fast.

[@TIMEPHYSICS]

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. Time dilation in gravity can be precisely calculated with point escape velocity but not by acceleration. As escape velocity at schwart radius is close to speed of light time also stops.

[@MichelvanBiezen]

This is indeed a controversial topic. It is generally accepted that centripetal acceleration caused artificial gravity which in turn causes time dilation. we have videos that describe what happens near a black hole.

[@TIMEPHYSICS]

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

[@MichelvanBiezen]

We have videos on black holes in the astronomy section if you are interested.

[@hjghgg371]

Thank you 👍

[@MichelvanBiezen]

You are welcome

[@photon434]

Professor, Fascinating topic! I didn’t know that centripetal acceleration causes time dilation. A Science ABC article spoke of a known supermassive black hole spinning at 84% the speed of light stating that this is the maximum allowed speed limit for a black hole. If it could spin any faster, the singularity would reveal itself and the laws of physics would break. This seems to tie in beautifully with your lecture. I would be very interested to hear your thoughts. 🌪

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

[@MichelvanBiezen]

We are not familiar with Ayanamsa

[@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?

[@MichelvanBiezen]

Increased gravity slows down time

[@zakirhussain-js9ku]

​@@MichelvanBiezenDo all motions inside spaceship also freez as clock stops ticking at event horizon. If so, how do E&M fields of Photon keep oscillating?

[@iugoeswest]

Schwarzchild! Woot woot!

[@MichelvanBiezen]

👍

[@Znxjsjnsdn]

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

[@MichelvanBiezen]

If the calendar was not adjusted we would eventually have winter in July in the Northern Hemisphere.

[@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?

[@MichelvanBiezen]

The artificial gravity created by their orbital path is very small compared to the effect of their speed.
