So say there are two twins. one twin gose on the journy at the speed of light, according to the calculation, no time will pass for him on the 11 light year trip. but by the time he gets back, even though it had been a couple secondes to him, 11 years has passed on earth, his twin therefore, is much older.

this is all in what Grinenshire said, only in more detail, I was bored and felt like typing something.
If someone goes in the speed of light wouldnt they die?
Just a question, Im not stupid or anything
