Oh, so crashing into a comet will help us stop world hunger, cure cancer and end global warming.
Do the words, 'get real' mean anything?
Do the words "don't be short sighted" mean anything? Expand your horizons... science is a good investiment. And depending on the material of the comet, it can end being usefull for global warming as well ... although it's much better to find out our origins... and know better the universe we live at...
And, Koma, you could have used some better wording. There was no need to insult. You don't need to lower yourself... for nothing... or a stupid discussion. Honestly, I hope I won't see this kind of thing from you again.
