In a way, you've written one of the best OPs in this section for some weeks. If you'd pimped it out with a few links and maybe a video, you
could have had a hit on your hands. It's starred and flagged from me anyway.
The points raised are the kind of things most guys who post in this forum don't know about or don't understand. In particular, our Solar System alone
is bloody enormous. At the speed of light, it'd take between 4 and 5 hours just to get to Pluto and getting near to 8 hours to
the edge of the Solar System (cool image).
When we get to that point it's another 4 years
to the closest Alpha Centauri! A list of
shows a bunch of stars that *probably* don't have what it takes to have developed intelligent life....too hot, too cold etc.
Out past the heliosphere and deep into real space; planets are there, but so far Earth-like ones are rare. We're currently in the mid-500s for *any*
planets found. There's a daily update
and a detailed list of
discoveries (mass, distance etc).
The distances and emptiness of space are mind-boggling. Nevertheless, if *some* reports are accurate, something technological appears to be
occasionally in our air-space...
Now, however rare and far away their home planet is, I would say that would be pretty miraculous to the people of Earth, if they were to encounter the
visiting aliens who can walk around freely on our planet.
I would assume if we are being visited regularly, most aliens probably couldn't even exit their ship, because our planet might be too extreme for
Up to now, it's possible that we don't have much of a clue without knowing the parameters. If we *did* know the parameters, we wouldn't be having the
discussion! There's a fascinating article by Professor Mike Swords that looks at the evolutionary aspects of ET. In the article, he broadly addresses
what environmental requirements would be involved for a technological ET to exist. Some of his points and some of mine...
* The planet/s or moon/s would require similar atmospheric pressure and gravity for the right atmosphere for intelligent life.
* They'd need to be land-based.
* The atmosphere would be similar enough to Earth to be able to sustain fire.
* They'd be apex predators like us.
* They'd develop tool-use and fire.
* They'd probably be 'humanoid' in shape as it's a good template for a sentient creature able to be instrumental on its environment: hands, binocular
vision, upright etc
* They'd have a societal infrastructure because construction requires communication, probably trade (economics) and the exploitation of resources from
different regions of their environment.
If most/any of these points are close to being reasonable, it might not be a huge adjustment for some technological life-forms to be able to function
on Earth. If their earlier development followed a similar path to ours, I would imagine their 'history books' would tell much the same tales of
conquest, wars and progress. It's a lot to consider and I know it's also speculation, but it's also, to me, more practical than other concepts that
describe peace, love and razzamatazz aliens.
The vast distance aliens would have to travel coming from a planet identical to Earth, must be millions of years into the future/more advanced than we
are, and also very rare in the Universe.
Maybe or maybe not? They could be thousands or hundreds of years more advanced. Then again, their science might have discovered something that we
haven't yet and earlier in their development than ours? Who knows? Also, could it be possible that ETs have left their planets behind? What if there's
an ET race or races that spends all its time in space? In that light, we could potentially have had an outpost parked in our Solar System from before
the dinosaurs. Planet Earth could be just one of many outposts linking up stars, moons and planets that have in-demand resources.
