Hi all, After the 'big bang' it is said that space is expanding. Atom is almost 99% space then why are they not expanding, same can go with all the stars and galaxies and all stuffs. Hope this is not sounding crazy. If so pls forgive me. Cheers.

phinds, by no means I mean you ppl are wrong. But found this theory is confusing.

exactly, there is no way to know I am slowing unless I stop by my say imaginary twin and compare the watches. But when we meet after long time, my watch will be behind to that of my twin, that proves time was running slow for me, and so should the speed of light should be 0.5c inside the space lab.

Ok let's say one gram particle travels at 0.9c. Now

At phinds, I know he will not feel time dilation coz he is part of the system, he too will move like sloth for out side observer. So whoever is feeling time dilation its a observable and physical thing. I found it difficult to understand that speed of light is constant with all frame of...

about the "makeup' answer

Twin paradox says one of the twin will be younger if he is traveling at the speed high enough to notice time dilation.

:DD:DD:DD

No friend I said source of light not light. Let say a star.

My frame of reference is source of light towards which I am approaching.

ok... then what made lead actor in movie 'Interstellar' look younger than rest of the universe. Am I making sense?

Is It? but don't we apply time correction to GPS satellite to provide proper coordinates. And in 'Interstellar' movie time dilation is shown in the form of one of the actor getting 'physically' old. My understanding was time slows at great speed, so I too slow down at that speed so I don't feel...

Hi all, After reading about Einstein's theory of relativity I have few questions as follows 1. Let's say I am in a space lab which is traveling at the speed of half of the speed of light. So when I try to measure the speed of light coming from space I record it as 'c'. Time is running slow...

Sapce time curvature is gravity right. But without mass curvature in space doesn't exist. It is dificult me to understand mass can affect absolute nothing ie space, but can't affect energy particle like photon.

It is said that light particle being mass-less charged particle are not affected by gravity but space, which is mass-less and charge-less get warped by gravity. How come?
