This is using the fact that at 1g acceleration, one will quickly approach the speed of light relative to its starting rest frame and time dilation will give the astronaut a _very long_ life relative to that frame.

The closer to lightspeed you get the more shit you would collide with. I think you would reach an equilibrium speed where drag balances thrust?

And hitting a microscopic speck of space dust would be like a nuclear explosion.

Ahh fair enough. Guess I wasn’t measuring the length of the observable universe in the frame of the astronaut…

Not the OP, but I'm on the same program in NC. You can set a minimum level to keep your battery that will cover at least short power outages (mine is set to 20%). You can also decline to participate with a limited number of VPP events a year.

The episode (_SURVIVAL_) that stuck with me as a kid was the one where Col. Foster is lost on the surface of the Moon with an alien and they have to work together to survive. The end of the episode was gutting.
