: I'm not thinking we'll be able to do the Star Trek thing an just visit other
: worlds and breathe their air and feel their sunshine and drink their
: water. We evolved to live in a specific gravity with a certain air mixture
: and with a plethora of microbes, bacteria, and such living within us.

: To live on another world without environmental assistance (domes,
: artificially grown food, etc.) is still going to be the realm of science
: fiction for a long, long while.

: Not meant to be a downer, but that's how I see the reality of offworld
: travel.

Sad but so true, oh how fragile life is when taken out of the environment it evolved in and adapted too. Just to travel to exotic lands and/or mingle with foreign people forgoing the aid of modern medicine and a person can succumb to deathly disease, or be death itself to the local populace(poor Mayans...). Now imagine a being on a different planet where not only has evolution progressed in a different manner, but life may not even be carbon based(I think around 5 types of lifeforms with a different basis has been discovered, such as insane group being arsenic based, could be wrong... pulling memory from science shows I watched as a kid.)

However, I feel safe assuming that by the time we can colonize other planets we'd have developed some sort of super immune system, whether by forced genetic enhancement, some sort of nano tech, or some super antibiotic.

I've always wondered what it'd be like to be able to say, "ya, the fam and I are just goin to Glaagoonion to visit the in-laws for Christmas break, the 3 moons are supposed to be somethin else"
I'll put all my eggs in the time machine basket I guess.
