Might be old but new to me. Pretty cool =)

[Phoenix]

Pretty cool.


Just imagine all fun shit that you could come up with to do in zero G.

[HackingJeff]

Awesome.

[Tuco]

I still want to see a Zero G fire.

here you go tuco

has a image of a candle on earth and one in space.

Thanks. That's cool how it's all blue.


First thing I thought when I read my posts, "Hey asshole, go look at the sun."

NASA is delaying several dark matter/energy research programs so they can fund pseudo-science like this?

I might be able to draw some funding away from CERN if I spin an ant farm around in a 5 gallon bucket over my head...

I wanna see what a nuke looks like in space. Have they ever done that? I guess with all the satellites around, they'd have to launch it out pretty far from earth. I wanna see a video of that, would probably look pretty cool. =)

Physic's Theory would have to answer this question, but doesn't the way a nuclear bomb work kind of make it non-combustable in space?

I mean, doesn't photons or electrons or neutrons shoot out of the atoms, cause a chain reaction and just blow the hell out of stuff, with nothing to cause that chain reaction won't it kind of... fizzle?

That candle is pretty cool. And from what I understand (very little physics knowledge) the 'explosion' is just an expansion of the particles released from the reaction of the uranium or plutonium or whatever they use that are really fucking hot and really nasty and cause damage that way, doesn't work like a conventional bomb that needs oxygen.

just how much fucking money does it take to pop a water balloong and light a candle?

Actually the main effects of a nuclear bomb are the pressure waves. I don't know how it would stack up in space, but on Earth most of the damage is caused not only by the heat (in a certain radius) but by the massive pressure change the explosion causes (which goes much farther than the heat). While on Earth you need not be terribly accurate with a nuke to lay waste to the target, in space I imagine you would have to get a direct hit to be lethal to a spacecraft since the only pressure wave you would get would be from the material the bomb is made from.

Mark Weislogel - lol

He's a professor at PSU, where I went to school. I sucked ass at fluid dynamics and shit, so I went HVAC instead. It is cool stuff though

Considering they are building the international space station to do "experiments" like this I'd say several billion.

NPR other day actually had several NASA scientists bashing the types of work they are doing and wanting to do on the space station. The experiments they talked about were "I wonder what would happen if..." Jr. High science project material.

As for a small nuclear explosion in space, one would think it would work like a star with the reaction pushing out and gravity keeping it in check by pulling it back together till it reached equilibrium in a sphere.

In reality though, the material near the explosion would not have near the mass of a star so the gravitational restraint would not be there. The reaction is short lived too, so the effects would disperse quickly in all directions as radiation.

If a small nuclear explosion happened in empty space it would be rather unspectacular. Guessing just a brief flash of light. Without the matter to carry the pressure front or react to the radiation you would just see a wave of photons for a second.

well lets get them to set off a small nuclear explosion in the space station to see what happens.
