Creation & EvolutionForum for the discussion of this important topic. This forum is open to non-believers. There is a Christians-only forum in the Christians-only section too.
Oh..I thought he was being sarcastic....you mean he is SERIOUS?? Oh ummm, welll...yikes. You mean he thinks a song actually falsifies the Big Bang? No, come on he has to be kidding..Fozzwald, will you clear this up?
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.

so why not have light push something?" A laser blasting against like a mirror or something that would eventually propel a ship to near light speed..
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.

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.
You really didnt expect him to stay did you? After insulting a priest and all.
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?
