hi all
I'm new to this site ,having read a briefer history in time I've been left with loads of questions that i cant get my head around....
if i took of in a space ship would i be moving in space or would space be moving outside the ship?
how can i measure speed..OK i could be moving away from the earth at speed but you could argue that it is the earth that is moving away from me...
and i could be moving at an even greater speed in relation to an object that's allready moving at a terrific speed away from the earth and me ....
if my speed cant be measured then am i going at the speed of light to a photon of light moving in the opposite direction
am i moving???
