Relativity(Light years)? PLEASE HELP!
Imagine an astronaut on a trip to Siris, which is 8 light years from Earth. On arrival at Siris,
the astronaut finds that the trip lasted 6 years. If the trip was made at a constant speed of .8c, how can the 8 light year distance be reconciled with the 6 year duration?
E=mc^2
I don't know how to solve this question...8 light years-> 6 years. 3/.8c??
Please help!
