Edwin Hubble said universe is expanding at the speed faster than light. Galaxy at 14 billion light years are going far away from Earth at speed of light. Some galaxies farther than 14 billion light years cannot be seen by human as light will not reach to earth. Why it will happen if you all say...

Please refer below image for better understanding. My question was what is the speed of light at s1 and s2 when the source is moving at speed (v) where v < c and near to c?

Let me simplify the question further that is the base of time dilation. One object has laser source at front side (s1) and back side (s2). If that source travels from point X at the speed (v) near to the speed of light (v < c), where the front side is towards the direction of the motion and...

Thanks Dale! Here I am modifying the question for better understanding. Assumption: Object 1 is moving at the speed (V) near to the speed of light C (where V < C) and object 2 is static. Both objects have light clock where the distance between source/detector and mirror is d. According to...

Dear Phinds, I was trying to understand which object will see the difference in watch. Time of object 1 and object 2 are absolute that are readable at any space time. Now if time dilatation happen, which watch will have slowed down time. Please help me understand the practical result if we have...

Assumption: Object 1 is moving and object 2 is static. It is impossible to say which object is moving without any reference object 3. There are three scenarios possible. 1. Reference object 3 is at same position in space time with object 2, then object 1 is moving and object 2 is static. 2...
