If the Sun blows up at some instant and four minutes later we on B to eat lunch, those two events are separated by a spacelike interv blowup cannot possibly have influenced us at the time we sat down, be 8 minutes for light to reach us from the Sun. And since the interval there must be a reference frame in which the two events are simultan speed of this frame relative to the Sun-Earth rest frame.

If ever the human race would need to leave Earth, the Trappist-1 system might make a good destination – the star there has seven temperate terrestrial planets, a few of which are close to Earth’s size and mass. It’s 39.6 light years away, though, so it could take a long time to get there. (a) If the spaceship had a speed of 0.95c, how long would the journey take from the Earth’s reference frame? (b) How long would the journey be for the passengers on the spaceship?
The spaceship Lilac, based on the Purple Planet, is779 m long when measured at rest. When the Lilac passes Earth, observers there measure its length to be 724 m. At what speed v is the Lilac moving with respect to Earth? Express your answer as a multiple of the speed of light ?.
