If you enter our galaxy, you're entering every galaxy our galaxy has ever been with. Use space protection. Then it's ok.
Yeah. I think we need to not have our entire species on one planet. <br />
I also think we ought to be working out how to build a manufacturing ba<x>se on the moon, so that we can make our intraplanetary travel ships where there's a LOT less cost to get them out of the gravity well.<br />
We could make our ships there, colonize Mars, mine Venus for useable materials and then colonize the outer system.<br />
Either we get off the planet eventually, or sooner or later our species is going to go extinct. <br />
As annoying as we all are, I have hope for my species to surmount this challenge.
Why the **** kind of question is this?
Not sure about space travel, but getting materials from space and bringing them back might not be.<br />
Everything that leaves earth is one less thing that will give earth mass. One less item that will be ultimately recycled. (even if it takes so long that it gets sent under the crust eventually) So I guess taking to much stuff away could be harmful. Meteorites do come in often though, even still.
WTF Does exploring space have to do with morality?
Please don't. I'm guessing it has something to do with some new made-up religious bullcrap.
Yep. Just what I thought. religious beliefs. You can stay on Earth, I'm going to Mars.
