Space

PS biosphear had problems way beyond technical ones. Its science and repurarion was ruined by a number of issues. Some fair most media atracks. These prevented the project gaininf funding to resolve the issues. The summation of it though was. They did not sell the idea thar an experiment is really not a solution. So were attacked when they had to introduce new input.)

Oh yeah I was just saying that I vaguely remember one of their problems being that they had some sort of… uh, was it algae or fungus that tended to grow a bit out of control.

But in any case I didn't mean to come across as saying we shouldn't try; we absolutely should, because we can't know if it's actually possible if we don't even try.

My point was more that there are a lot of significant problems related to space colonization and many of them much bigger than many people assume, and some fairly credible people who are actually either in the aerospace field or are researchers etc. have said that it might be that the problems are big enough to make self-sustaining space colonies nearly impossible for a long, long time. But like you said as well, that should be a reason to start learning and not limit whether we try
