On: Sending a spacecraft to Alpha Centauri

[duggan]

I always liked the concept I read about in an Asimov short story years ago; the (rough) idea being that you somehow "pin" a ship/probe to the CBR/fabric of the universe and let the solar system / galaxy accelerate away at 2.1 million km/hr.

Note: I am obviously not a physicist, so feel free to demolish my fantasy :)

There are no preferred inertial frames, etc etc. It is a cool idea though; something to keep in mind in case relativity is ever subverted.

Sounds like a one-way trip

Much like time travel if it was possible.
