"breaking" the speed of light limit.
I couldn't quite figure out how to describe it shortly hence the weird title.
I was wondering what it would "look" like if the following situation happened.
Lets say you have a space craft. It is going at a speed of 0.7 c. in relation to star X.
Accoording to special relativity (or was it general relativity?) you could also say your spacecraft is not moving and star X is heading in the opposite direction at a speed of 0.7c.. Correct?
But, in "reality" you are the one moving.. Now..
There is another spacecraft heading in the opposite direction at a speed of 0.7c in relation to the same star. The spacecraft meet... So.. you get the folowing situation..
a = Spacecraft A
b = Spacecraft B
c = stationary star.
a ====> c <=== b
The velocity difference is 1.4c.. more then the speed of light..
Now I understand that none of the spacecraft is actually moving faster then the speed of light, but from what I understand it is fair to say that spacecraft A has velocity 0c and B has velocity 1.4c.
What would that look like from the perspective of spacecraft A? How could that possibly be turned that B has a velocity of <1c?
I hope I'm making myself clear. I'm heaving a bit of difficulty trying to formulate my question.
