This is one of the most interesting topic so far.
is time travel possible?
everyone say that time travel is not possible but actually it is possible.we all have been time travelling. from last year to present we all have actually time travelled. but the question is-
can we travel at a faster rate then 1 year per year?
Albert Einstein developed a theory called special relativity.This theory says that space and time are really aspects of the same thing—space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.
also, this theory says that if we travel in space time or when your speed relative to other objects is close to the speed of light, time goes slower for us.
like, suppose we left earth on 2005 and spent 5 years there then on earth it will be 50 years.so when u come back from space after 5 years it would be the year 2055.
