I have been thinking about extraterrestrial life recently, and was wondering about what y’all think of it all. Do aliens exist, or are they just another piece of nonsense on this lonely planet? I personally think they should be, in some form, real. This is why I think that: (a) This universe is HUG…

There’s probably life in other parts of the Universe, but since it originated and evolved separately from life on Earth, it is likely different, for the most part, from life on our planet. But perhaps it has some features in common with the life we know, since we have observed that some traits, such…

To answer the question seriously, though, I have not the slightest doubt in my mind that Life exists in the infinite vastness of space… it would be inconceivable to imagine that it doesn’t. I would guess that it will take a form that might be unrecognizable to us… look at how different a slug is fr…

I think, on first glance, life on another planet will look surprisingly similar. That is because functional constraints are largely universal. On second glance, the evolutionary history of these organisms will likely mean that there will be totally different approaches to the same structures (hist…

Personally, I doubt that life exists on other planets. I think Earth is a special place. That doesn’t stop me from imagining what alien life could be like.

Mainly, I think that sci-fi writers tend to be biased toward bilaterally symmetrical forms. Who says intelligent life has to be bilaterally symmetrical or even capitate? Picture this: a being shaped like five rays, no one of which is the “front” or “back.” It can walk equally well in any direction …

[image] jasonhernandez74: On another planet, picture this: a being where each type of body cell – digestive cells, oxygen transport cells, reproductive cells, nerve/brain cells, etc. – is diffused throughout its body, which therefore does not need to be a particular shape. Its intelligence is al…

I am sure that life equivalent to bacteria and archaea exists on other planets that have liquid water and fairly stable histories going back a few billion years. I expect those organisms to be based on carbon, as we are. We’re most interested in multicelluar organisms. (I expect large organisms t…

[image] jasonhernandez74: Who says intelligent life has to be bilaterally symmetrical or even capitate I think bilateralism might almost be a prerequisite for intelligence. (Though, being bilateral myself, I might be biased :P) To me it seems like radiate organisms don’t really benefit from …

Whether we find extraterrestrial microbes or actual little gray men, it will be interesting to see what the taxonomists do with them.
