you are an advanced alien civilization that has mastered transd-light travle, and you come to a planet made up of 70% of the one compound that is corosive to you?

not only is the atmosphere corosive, not only is the usrface of the planet covered int he stuff, but the cooling and ecology of the planet is such that this corosive substance actually falls from the sky ona regular basis...

and knowing all of this, you leave you ship. BUTT ASSSED NAKED!!!!

are we as a huiman race going to say, venus when we know the atmosphere is made of arsnic and sulfur...NO!!!

sorry
