I was reading about time dilation and suddenly a question raised in my mind. (This might be a misconception but please do correct me if I am wrong)
I read that if we travel near to the speed of light,time will move slow.
My question is this.
Suppose a rocket is traveling from earth at a velocity near to light .Another rocket traveled to mars with ordinary rocket speed and suppose after traveling one year, both rockets had reached back to earth.So according to time dilation when the first one reaches earth, let's say that 50 years has passed on Earth. So the people on the first rocket will live on Earth after 50 years. But the second rocket did not went in the speed of light and will happen to see the same earth after 1 year. But how can both rockets see different versions of Earth at the same time?
There is big chance that this question is wrong, but please explain and correct me about time dilation.
