What is twin paradox?

TWIN PARADOX is a paradoxical situation coming in while explaining the theory of relativity. “Time dilation” is one of the important consequences of relativity. It says that if a body is moving with relativistic speeds, time will dialate ...

An interesting question based on Relativity (Time dilation and the Twin Paradox)

Yes, this is similar to the twin paradox, but with a few changes: Two brothers set off from earth to make a round trip of 30 light years in total. The first brother, say Albert, has a ship that travels at 10% the speed of light so his journey will take him 300 years and, [...]

Idea on origin of Gravity – A discussion

Derek shares his idea on origin of Gravity – “if you were to suddenly put a large object in space then the space would  be pushed out to the sides (displacement) . because the object  is now in the place were space once  occupied ?? so space is just pushing  back to its original area ???? is this what gravity is??? or [...]

What are Tachyons?

What are Tachyons? This question was posted by Vimal Raj. Answer: Tachyons are hypothetical particles which always travel faster than light. The idea is that, if there is a particle which travels with a speed less than the speed of light, it will never cross the speed of light. But if there are some partricles ...Read the full post
