Right – travelling (+)
Left – travelling (-)
Where the lines are, can’t influence us.
Why can’t you go faster than light:
1) Massive objects – can’t accelerate to higher than C, because
mass becomes infinite.
2) Is it because length contraction and time dilation? Not really ->
there is a way to getting around discontinuity.
o Supersonic jets that exceed the speed of sound.
3) Real reason (most convincing reason) is causality:
o Only things that happen in the past can influence things in
If you have faster than C travel, combined with special
relativity, its possible to send yourself messages in the
Paradoxes result when travelling back in time.
o You c
