Nice photos. But what is gravity ? Do you think it is instantaneous or not ? Some believe it to be instantaneous action at a distance ( Newton's Third Law) while others do not, called it curvature of Space-Time ( Albert Einstein) ...........only to change his mind, later. Some justify the...

"time dilation is a true physical phenomenon" As A body accelerates closer to the speed of light, all of its extremities and intrinsic energies expend velocity, "for example" if a star where traveling near the speed of light then the orbiting moon or planet would have to slow down in order to...

All these interesting URLs and more by doing a search " is time dilaton real lefteris " with browser DuckDucKgo.

Another very interesting URL about whether time dilation is an illusion or not: https://physics.stackexchange.com/questions/53009/is-time-dilation-an-illusion Search Summary: "Time Dilation is real insofar as it tells us the rate at which things happen in one reference frame relative to...

"... so that objects that move will experience less time expended than before they began moving..." The above statement hold true overall in moving from A to B. You will be covering the distance in less time. Any images leaving after you, will not be seen by you. However, images coming...

I think, you may be getting confused. It is a simple experiment, nothing complicated. Both experiments are of, as you put it, an appearance issue. Two identical clocks, tower clocks, separated by a suitable distance, showing identical time with Albert Einstein in between them in his tram...

The thought experiment was based on the same procedure as adopted by Einstein and his subsequent reasoning, time slows down at faster and faster speeds. nothing else, nothing more. We are looking it from the Einstein point of view with the tram car (spaceship) moving now towards the clock, as...

To put it a different way, why TIME DILATION is an ILLUSION as well. The author of the clip claims Einstein came to this conclusion -time stands still at the speed of light- or -slows down progressively as the speed approached the speed of light. By constructing a thought experiment...

..... now, you may ask is there movement on a TV screen. If your answer is NO, you are right, there is no movement on a TV screen playing a program. Just a lot of still images which our eyes in combination with our brains cannot resolve and see the whole scene as movement. Therefore, movement...

What do you think ?

Another aspect of light in a vacuum experiment, this time light moving slower, the URL : https://www.iflscience.com/physics/speed-light-can-vary-vacuum/

I understand your thoughts. And I take it you mean space been the emptiness between objects, such as between planets, star and planets, asteroids, etc. etc. You may say, the space is the boundless "playground" where all the events of the cosmos that we see or don't see take place. On the other...

I would say, very very much less than the speed of light. To think, in other words, is via neuro chemicals, , very slow process. To think about something, takes about a second. You are confusing speed with thought forming or accessing your memory. Here is a simple test. Ask a friend to...

It makes very interesting reading about the speed of light: https://lefteris-kaliambos.wikia.org/wiki/CONTRADICTING_RELATIVITY_THEORIES Part of the article: " THE GRAVITATIONAL RED SHIFT REJECTS EINSTEIN’S “EQUIVALENCE PRINCIPLE” AND THE FALLACIOUS “ETHER STRUCTURE” Olympia 1993...
