Space exploration/colonization

[Blue3]

Support it, but there's quite a few higher priorities right now.

Space colonization won't really happen until there's profit to be made in it, enough to outweigh all the costs and risks.

What do people think of NASA idea's of sending advanced 3D printers to the Moon and Mars, to construct shelters and objects from the surrounding materials, so not all of it has to be shipped from Earth? That would significantly decrease the costs.

Also terraformation could happen, but over a very long time. I remember reading that if we put enough of a certain bacteria on Mars, it could transform the atmosphere to be thicker/warmer and generate enough oxygen for the air to be breathable for humans... after about 200 years.

The odds are quite likely that we're not alone in this galaxy.

I remember an old book of mine saying CFC's could be used to warm up the atmosphere.

Well, there is that Martian rock discovered in the 1990's that seems more-likely-than-not to contain fossilized microorganisms.
