| Re: Life on Other Planets I'm not 100% about it, but I remember hearing somewhere that Venus is pretty close to what Earth was like when life first began, while Mars could be what Earth would become if aged enough, as long as Earth gets that old before the Sun expands & swallows up all the inner planets. So, if you think about it, Mars could have evidence of now extinct life, while Venus could have it's first single cell lifeforms coming to life as we...write?
I don't think Gravity would be a problem, since from memory it's essentially the same as Earth's, plus if life does form there, it'd have to be created to survive the local weather or die in no time. Survival of the fittest tells us, if you're not rigged to cope with your new home, you die pretty quick... |
