It appears that he is being cheeky, but I assuming he is referencing a common presupposition in western metaphysics, which I can't remember the latin name of. But it can be summarized as "nothing comes from nothing." I am not a philosopher, but the scientist in me wants to say "that depends on what you mean by nothing." Three thousand year old greek philosophy is fun and useful, but I think in some ways it hasn't kept up with our current state of knowledge. |

I certainly do not want to be the one to crush your boyhood dream, however, there is the small problem of YOUR mass and the mass of the space ship becoming infinite!!!
I hate to crush yours, but lightsails have been investigated for powering spaceships. If you have launching lasers you can get a respectable fraction of c for final velocity. Better than what you get for conventional rockets because you don't have to carry reaction mass. Larry Niven and Jerry Pournelle used the concept in their book The Mote in God's Eye. |

:rolleyes: You're serious, right? Check out www.reasons.org and find out what a Christian astronomer thinks of this argument.
Now, there is a company formed to investigate getting energy from the nothing of vacuum.

You're surprised?? Poor KiwiChristian is one of those who reads creationist sites and thinks that is the last word. Then he came here and found out that not only didn't anyone believe the argument, but everyone had heard it before and had all the counters ready.
He's probably in shock. |

The funny thing is that trolling like this, does nothing but hurt his side, unless of course, thats what he wanted.
Speaking of light propulsion, I was just reading in Pop Sci about one plan to deflect an asteroid heading towards earth. It was to coat one side of the asteroid with a reflective metal, then either use lasers or the suns own light to shift the asteroid away from a colision with earth.

Lasers? What the?
Is it somehow using the idea that light has some mass and thus can push an object?
