before the first man on Mars or later ?
Or will we see humans on the moons of Jupiter and Saturn before anyone
gets to Venus ???

I was reading somewhere that they made the first light antenna. I suppose
that would make it 100's of times quicker than radio signals.?
What if Aliens only ever used this type of signal for communication has it
ever been tested for.?

I know we have 100's of antenna's looking for readio signals from other
planets but do we have any looking for this type of signal already.

Can you fire a gun in space? Will the powder burn? And if you made the
reloads in space in a vacuum would they fire?
Will dynamite explode in space?
Will a nucular bomb ignite on the moon?

I just finished reading Brian Greene's "The Elegant
Universe". The section in chapter 15 titled "What are
Space and Time, Really, and can we do without them?"
suggests in my mind a tantalizing question:

-> > Asteroid (4179) Toutatis to Pass Closely By Earth on Wednesday, September
-> 29, 2004.
-> Apparently it'll only be visible in the Southern Hemisphere then, but in
-> early October it'll be visible in the Northern Hemisphere...(with

I would've posted this question in the chemistry newsgroup but the
people in there seem like idiots and I fear it would never get
answered. Heat is defined as the vibration of molecules right? Well how
does heat then travels through a vacuum?

I'm still seeing only b&w images of Saturn - when can we expect color? Surely
it's been there long enough.

A phase transition is when a system resides at
the critical point between it's static and chaotic
attractors. Such as a cloud residing at the critical
point between water and air.
