bullet I recently found out about Lake Vostok in Antarctica and it seems quite facinating. I've been trying to find more information on it but haven't been able to find any
bullet When an orbital vehicle escapes through the Earth's atmosphere is it possible that this reduces the greenhouse effect because of the opening in the Earth's atmosphere or does it add to it because of the fuel that is being burned to get the orbital vehicle out of the Earth's atmosphere?

bullet Is area 51 hiding u.f.o ?
bullet What is earths surface like ? I have another couple of questions to ask as well: What is its atmosphere like ??
bullet My son (11, in 6th grade) and I were having one of those open-ended dinner conversation and he asked me whether there is a living organism that didn't require water. I simply didn't know. My rudimentary understanding is that water was indispensable.
bullet I just saw the excellent film Cosmic Collisions at the Rose Center in NYC with my 14 year old. The film does a wonderful job of explaining how the moon formed from the earth. But it raised this question I couldn't answer: Why do we think the Moon didn't form an atmosphere and some form of life but Earth did given that the Moon was cosmically next door to the Earth?
bullet Hello Im one of those kids who is obsesed with zombies and the whole virus called solanum and reanimation of the body. But is it possiable to shock something so hard that it actually brings it back to life but only with a primative instinct?
bullet What role did stromatolites play in the evolution of life on earth - was it used as food for new life? What new life could have used stromatolites for their nutrient needs? How did this effect the changing environment on land and in the seas?
bullet If we started simple biological communities on Mars (ones that require very little to survive), would they start to evolve? Earth has the sun and other properties that have caused it to evolve. Did it evolve because it needed to for life? Maybe by adding life to Mars it will cause some polarity to other properties (needed for life) that would start an evolution on Mars.
