Question

Relating the Special Relativity, why does a moving (say a light clock, consisting of light bouncing between two mirrors. As the light hits the and is reflected, the clock gives out a “tick”. The two mirrors are separated by distance d) have greater time than a stationary light clock.

Answer 1

What can change when you move?

Answer 2

sorry, why is time 't' different

Answer 3

Ok.
Because the distance between two mirrors increases.

Answer 4

This LOOKS like a SPECIAL RELATIVITY TIME DILATION question. MOVING clocks keep SLOWER time than STATIONARY clocks.

ps Similar diagrams are used to demontrate E = mc^2

Answer 5

@DarrenGebler in special and general relativity the concept of "time" as such MERGES with that of "space" to produce the (possibly bamboozlingly irritatingl mesmerising) "space-time". "Times change", as they say, BUT this time it's from reference frame to reference frame when there's relative motion involved. And the FASTER the motion the more the space time and thus time change ...
And, when it comes to general relativity, some "maniacs" (Einstein et al) decided that "space-time" was also CURVED or at least it would be curved near a MASSIVE body eg a planet.
Just to give us all a real head banger of a headache, AE and his wife Mileva cooked up the idea that, in their world (super fast speeds - forget Bolt and Formula 1, and dragsters etc) you had to talk about "MASS-ENERGY" which is what E=mc^2 is sort of all about.
(Some of us, at least one, sometimes wonder whether it would just be simpler to locate a brick wall, lower the head and run straight at the wall .... )

Answer 6

Going to "CURVED SPACE-TIME" as a pretty horrendous thing to try to post, I think that the more massive something is the more it "bends" space-time, whilst if there's no mass around, then there's no "bending" or curvature. There's a fair number of pictures of this on the internet, may even be one on

Stepping back, though, for a tick from the imagination/mental demands of even trying to think about this, a leaf through an advanced school physics book will sooner or later throw up a POTENTIAL ENERGY diagram, much as there will also probably be a DISTANCE-TIME graph or two.
It seems to me that the PE diagram has been sort of "borrowed" by Gen Rel and "banged" into space-time curvature by whatever maths was required to do it.
And the distance-time graph has been again "processed" into what I think is called a MINKOWSKI diagram drawing the relationship between reference frames moving at high speed relative to each other.
The point I'm trying to make (and poss failing) is that there ARE analogies with low speed mechanics which have been used in the Spec and Gen relativity development - it's not QUITE "rabbit out of a hat magical genius", though it often seems to be presented that way.
It doesn't make it that much easier, but it might make it a tad less daunting and, dare I hope, a tad more accessible ?
