Thanks. Much appreciated!

What I mean is, if you travel at 87% the speed of light, then 1 day on that ship is equal to 2 days on earth. So, is there a lesser percentage of the speed of light at which time would be equal for both the ship and the people on earth?

What speed does a ship traveling through deep space need to travel at for 1 day on the ship to equal 1 day on earth?

How long/what distance would it take a spaceship (with a hypothetical propellant-less engine) to accelerate to near light speed, and secondly, how low long/what distance would it take to decelerate back to zero again?

Thanks very much!

I'm wondering if a ship orbited a black hole for a year, how large would the black hole be for it to equal 10,000 years on earth?
