I'm sat here with a cup of tea and a toasted crumpet getting a headache about this whole light speed issue.
Sci-fi would have us believe that travelling at the speed of light will be the one way to travel through the cosmos. I agree. To reach other habitable systems we will need to travel at ultra light speed or face hndreds of years in stasis. The problem arises with the navigation.
What we see in the sky at night is the stars as they were hundreds of years ago. They are bound to move and if we go bombing along at multiples of the speed of light we are likely to collide with something. Imagine driving down Tottenham Court Road at 80mph with your eyes shut, and that's what you've got.
The systems need to be mapped, so that navigation programmes can be designed that can predict orbits of other planets etc. Anything that goes out to do some mapping is going to have to travel at sub light speed, so it's going to take a while.
Thoughts on this anyone?
