Thanks for this. Clearly it's not going to spoil anybody's day in Alpha Centauri.
I don't think the acceleration happens quickly, I think it happens over months if not years. It has to get to 300m MPH which even at 1g would take 347 days. I think the acceleration is a lot less than 1G. If it...
Thanks for some great answers
"It would be instantly vaporized. But the odds of there being something in the way are quite small."
Yes but what would happen to the planet it hit?
And the odds are that it will hit something eventually before the end of the universe!

2 types of nano spacecraft are planned to travel to Alpha Centauri , 4.2 light years away. One powered by an Earthbound laser, another self powered.
I have loads of questions about this but here are a few

To throw in a wobbler, it has been on my mind for some time that nobody knows for sure what speed light travels at in interstellar or intergalactic space. We have plenty of evidence within our own solar system that it travels at C. We assume that outside the solar system it is traveling at C in...
