BronyMedic: We're running out of resources on Earth at an alarming rate.
TopoGigo: So, that leaves us with one huge problem: energy. Free or nearly-free energy would solve all our problems. With enough energy, we can desalinate all the water we like. We can filter landfills through huge factories to recover waste raw materials. We can produce fertilizers from hydrocarbons if we choose. Hell, if we really get cramped, we can launch orbital farm satellites. Whatever the hell we want, we can do with enough energy. That's what we can do as a species to ensure our survival. Personally, I like the genetically engineered algae that crap jet fuel as a solution, but there are all kinds of possibilities. Let's get the hell to work.
BronyMedic: Humanity's only way for long term (>150-200 years) survival is to look upwards and outwards
ThaGravy: Jubeebee:Exoplanets are irrelevant for future human habitation anyway. If you can get humans to an exoplanet, you can sustain human life in a spacecraft for a very, very long time, essentially indefinitely....With essentially unlimited energy, you could make yourself a rather comfortable life close to home, rather than spending a few millennia floating through the interstellar dark.I thought I would try to put some actual numbers to it...The distance to the closest star is 39,900,000,000,000 km away. (link)The fastest man-made object moves at 252,800km/hr (link)At that distance/speed, it would take 157.8 million hours (or about 18,000 years) to get there. The ancient pyramids were build roughly 4,500 years ago.
Jubeebee: If humanity is going to have any future in space, it's going to be around our own familiar star.
BronyMedic: Humanity's only way for long term (>150-200 years) survival is to look upwards and outwards.
SlothB77: It has found nearly 80 confirmed exoplanets with a similar size to Earth but only a few of those have the right distance from their star to support liquid surface water - the presence of which is considered essential to sustain life.ok, why does it have to be a similar size to earth? I understand it can't be too small to fit everyone if we all decide to up and move to it, but if a planet is twice the size of earth, is it incapable of supporting life then? I mean, besides those 48 hour-long days, what is the problem? will the gravity be too strong or something?
