FFQ: Speed of things travelling in space... - 03/19/07 08:45 AM
Okay - so I know that, as far as science knows at the moment, travelling faster than the speed of light is simply not possible. However, we're not talking about the 'real world' here .
Let's say a certain planet exploded 35 years ago and a certain spaceship and/or pieces of said planet landed on earth about 7 years later. Now, scientists just 'saw' the planet exploding last year - so it's taken 35 years for the light to get this far - meaning the planet is 35 light years away. So how much fast than the speed of light would the spaceship/pieces of planet be travelling?
Does that make any sense at all?
Planet 35 light years away explodes.
Spaceship/pieces of planet land in 7 years, but visible light from said explosion takes the expected 35 years. How much faster than the speed of light must the ship travel?
Or can I just stick with 'much' faster than the speed of light ?
