Eh? No inter-stellar travel required. Could've originated on Mars long ago, or maybe they fucked Venus over with global warming and had to head for the hills ;)

Possible... what do you guys think?? Maybe they're on a giant spaceship we haven't detected somewhere in the universe, like a space colony. With a docking bay where they send out their spaceships and shit... Maybe there's a reason they don't want to be detected. Maybe we're some sort of experiment...

I doubt that the technological advancement of any society advanced enough to get into space would have left no noticable traces in our solar system. Maybe, but I'd call it a very very long longshot.

It's possible, except for the bit about Venus and global warming... It's past midnight, so I don't wanna get into a debate about it, but I think your other ideas are plausible. Given, it would have to have been a long, LONG time ago, considering there aren't really any existing traces on Mars.

It's possible, but there's no reason to believe it's true.

Why would you live on a spaceship when Earth is right here? Unless you have a good reason for this, your theory fails.

You assume that life on earth is the only possibility for life. It's more likely that a race that evolved on a different planet would find Earth's conditions quite inhospitable. We'll chalk up the reason for the leaving in the first place to nuclear holocaust.

I assume nothing, but I guess my statement wasn't clear enough. You win that point. Isn't this topic something for the conspiracy thread though?

If we are willing to accept that there is a hidden spaceship out there from one of the planets or moons in our own solar system, then why should we just not assume that there is interstellar travel to our planet.

Part of science is proof and there is no proof at all for this type of idea; well at least that I know of.

Sorry I misunderstood you^^

In any case the question wasn't "there's life in our solar system" its "Could there be other intelligence in our solar system, Eh?" I personally don't feel it belongs in the conspiracy thread because of this. Also its interesting to poke at. Interstellar travel is immensely hard compared to intersystem travel. Its ben described as the difference between touching your nose and landing on the moon.

Most questions tat belong in the conspiracy forum can be readily identified by extensive criticism of the original post's sources of evidence, or train of logic. Like the regulus space thread.

can we see a source of evidence then? This is all conjecture until somebody finds chunks of a rocket ship somewhere. I therefore think it belongs at least in headshrinkers, if not conspiracy.

I find a better question is "How likely is it there's an intelligent race under the sea?"

Seriously, the earth is around 71% oceanic environment. Who's to say that a deep-sea intelligent race isn't alive and well right now?

As for these aliens, how are they capable of sustaining in an isolated environment in space? Even a space-station of epic proportions needs supplies, and if they were harvesting from any of our local planets (Aka within the asteroid belt) we would likely notice.

That's all assuming that "aliens" need sustenance similar to earth life, or sustenance at all. For all we know, there could be vacuum-powered aliens all throughout space. In xenobiology, anything can seem impossible until it's found. Only after people see actual evidence do they start to think of reasons why it should exist, as opposed to why it shouldn't.

There is a very real chance that there is extensive life very deep in the oceans that we have not discovered. Technological limitations are abound, plus a general lack of expeditions. The ocean is a very deep, very large area. Think about how many explorers (and how much time) it took until the Europeans had "figured out" the New World. North America is tiny compared to the ocean. We can speculate on the kind of life that inhabits the deep though.

Something that would be REALLY incredible would be finding a different kind of life deep under the ocean--species that evolved parallel to their shallow-water counterparts. Lifeforms NOT based on DNA/RNA. That would possibly be one of the greatest biological discoveries of all time. In any case, deep-water life has to have adaptations to survive at extremely high pressures without sunlight.

I certainly agree that the deep-sea argument is plausible, but everything needs sustenance, because energy can neither be created nor destroyed. In order to move, everything must harness energy of some form.

Well the sun puts off an immensely large amount of energy... you could do quite a bit with that probably.

On the note of non nucleic acid based life, yes. That would be no doubt the most amazing discovery ever made on this planet (besides fire, possibly). But what are the odds, considering our planet's chemical composition?

True, but if they photosynthesized or otherwise harnessed the light energy from the sun, they would still be restricted to the areas of the solar system approximately within the asteroid belt. The sun's energy is immense from our point of view, but i believe that it's energy decays exponentially over distance...I'll have to check that. If they were to travel to Pluto or beyond, they would have to make return trips quite often to recharge, and considering our recent mars exploration, we would almost certainly have noticed.

It decays as the inverse square of distance from the sun. So something at 50 million miles from the sun would receive four times as much energy as that same thing from 200 million miles. Pluto is roughly 40 times further from the sun than the Earth, so it would receive roughly 1600 less times energy.

thanks for the supporting data.

You have to remember that they didn't know that there were more than 9 planets in the solar system until 2007, I wouldn't overestimate our observational abilities.

(I know that pluto and eris were classified not planets, but not sure I'm happy with it.)

You know, if there is an advanced group of space men out there, I'm sure they are smarter than to bum around pluto. I mean there are like 90 stars in our galaxy, I'm sure there is a different party every night to go to.

You really need to check your facts before posting in MS...the first KBO was discovered in 1992.

Also, you're just a teensy-weensy bit off on your estimate of the number of stars in the galaxy. And nobody is arguing there aren't aliens flying around over there.

And finally, the highlighted represents a change in the argument, we were talking about our solar system first, that these aliens originated from and/or flew around here.

I've counted them. Don't BS me with your math and "science", I am perfectly capable of counting the stars in the night sky.

Can't argue with that.
