I read that page. And I understand that time dilation happens by either gravitation or acceleration. But the OP asks how it happens mechanically, and I can't answer. I imagine that both acceleration and gravitation act upon atoms in the same manner. Though I admit, the speed of light being observed equally in all inertial frames of reference kinda tweaks my noodle.

 

I don't have the words be explain it myself, but I will ask, do either of these help?

 

 

TimeDilation

 

LengthContract

Introduction to special relativity - Wikipedia, the free encyclopedia

 

This article aims to give a gentle, non-technical introduction to the theory based on geometrical intuition and explain some of the terminology and formalism involved. A more advanced, encyclopedic description will be found in the parent article Special relativity. It will be helpful to approach relativisic mechanics by first studying some properties of the classical (Newtonian) picture.

2. TimeDilation

3. LengthContract

4. ContractInvisible

5. Simultaneity

6. TwinParadox

7. Foucault

8. Precession

Modest: Also, someone in an elevator that is free falling toward a massive body like earth will feel weightless just like someone who is stationary in deep space outside the influence of any gravitational field.

 

Now this sounds like a real time problem, to one of these people what time it is will be far more important than it will be to the other. Hmmm.... I guess time really is reletive:doh: I couldn't help my self Modest, it just seemed so obvious that time would indeed be a probelm in this context. On the other hand if the gravity well was deep enough (black hole) it wouldn't matter to either one of them would it? Both situations would last forever from each others point of view.

Infinite!

 

Those Animation where great .. thanks for taking the time .... But im starting to get Scared ... Why does our Universe Have to be this way?

 

If PI measured just 3 .. Then i suppose we would take it for granted .

Yes, they're both pretty good, if not a little too simplistic. The moving detector could be two examples of the same event from two perspectives, yes? Rather than two events that last for different lengths of time?

 

The wiki helped me more, though. This section here:

Thank you sir for explaining that so eloquently. Ps why the "eye of Ra" in yer sig?

 

Talking about the " eye of Ra ", here is a video that is a mix of physics and religion. Although, this " PART ( 4 ) " is mostly about the simplest derivation of the Lorentz Fitzgerald Contraction Equation, the Time Dilation Equation, and the Lorentz Transformation Equations.

Oh, well. I suppose I could say it's because I don't miss anything... Uh... but, I apparently missed what you wrote there earlier :hihi:

:hihi:

 

Truth is, there's no particular cultural or philosophical significance - though I am particularly fascinated with ancient Egypt.
