Re: Where are the frickin' laser beams when you need them?

The only thing that keeps water liquid on the surface of the Earth is about ten tonnes of air pressing on every square metre. Something that hasn't even got enough gravity to mould itself spherical is a bit unlikely to be able to keep much of an atmosphere round itself.

When ice is warmed under a sufficiently low pressure or vacuum, it changes straight to steam without bothering to pass through water.

Look up "Triple point" and be enlightened :)
