HEY MAN I JUST THOUGHT, HOW FUNNY WOULD IT BE IF WE GOT TOP MARKS FOR IT!! AND EVERYONE ELSE FKED IT UP!
YAY FOR US, EVEN THOUGH WE PROB GOT IT WRONG!
Yay, someone else thought of that! That was my reasoning... I thought that the earth isn't really moving, only the spaceship is, and therefore the clock on earth must be slower. It only looks like it is moving from the astronaut's perspective but really it isn't.Originally posted by DC10
anyhow. i put D. i just realised after the exam it COULD be B - suppose B is the twin paradox? - the 'twin' on earth argues he's younger and the 'twin' on the spaceship also argues that he's young? something like that?
