Ancient Aliens

^ But like I said, why would aliens WANT to come to Earth? Any alien species that has the technology to even reach Earth in the first place is probably not going to consider us worth the trip. We would be the equivalent of trailer-park trash to them. So why would they bother?

Gathering material for the Green Collar Comedy Tour. Coming soon to an ansible near you.

I don't think even you believe that. As far as we know Earth is the richest and most diverse life-based resource in the galaxy. Any scientist worth their salt (or whatever equivalent compounds) would realise they'd hit the mother lode.

If you can travel through space and time, you could probably determine every possible chemical combination. Honestly that's the future of pharmacology, hit a receptor or binding site with random chemicals until something "fits".

Plus you are assuming that scientist are running the show. What if it's drunken frat boys.

You may think the ants from the nearby anthill unimportant.
But there are a LOT of scientists that find them extremely interesting and studied them extensively. The same can be said about every bit of the natural world.
Plus, it's worth noting that life is the most information rich phenomenon known to man; stars and black holes may have astronomical energies, but informationally, they're simplistic by comparison to a mere rat. Intelligent life and civilization is a further step above that.

And any species capable of interstellar travel must have a significant rational component (including curiosity/discovery, etc); 'drunken frat boys' - or their equivalent - just don't have the level of competency for such feats.

PS - We're already able to determine "every possible chemical combination".
That doesn't do us any good - the combinations are practically unlimited in number and only a vanishingly small number of them actually 'do something'; the rest is useless randomness.

But, again, I never said there was "nothing" out there, just that whatever may be out there is rare enough that, after decades of scanning the skies, we've found... nothing.
The point you clearly missed is that even if the universe was teeming with SPACEFARING civilizations, we would be extremely unlikely to know about it even after ten centuries of searching the sky with our telescopes. We've only in the last 20 years even confirmed the existence of extrasolar planets, and most of those only by their gravitational effects on their parent star; even at FTL velocities, something as small a a spacecraft would be WELL below our detection threshhold unless it was relatively close to Earth orbit.

In other words, they would have to go out of their way to visit us before we ever knew they were there. That in turn implies they would have to have a REASON to visit us, which -- if they don't know about us -- they would not.

I don't think it's unreasonable to be skeptical of claims that the universe is full of intelligent, spacefaring life forms, especially when you come up against comments suggesting that Von Neumann probes are almost within reach. Given that they are a fairly straightforward idea, the universe should be positively crawling with them if anyone had ever built them.
Except for the fact that Von Neuman devices are impractical for interstellar exploration, that would be true.

I also think it's essentially irrelevant if intelligent, spacefaring life exists but it is much too far away for us to ever encounter or even discover it. It might as well not exist, as a practical matter.
Which is true. If FTL flight is impossible, then EVERY solar system could be inhabited by intelligent spacefaring life and we would probably never know about it.
 
Which construction are you referring to? Not all of it was done through slave labor. The Pyramids were not, for example.

Um, that's literally what most pharma does right now.. it's called high throughput screening. Throw a library of randomly synthesized junk against your target protein, see what sticks.

I've pretty much randomly jumped into this thread, so this is totally out of context. But using terms like "receptors" or "binding sites" makes it sound like you're reasonably well versed in structure based drug design, so it seems odd that you'd think high throughput screening is the "future" of pharmacology, rather than a throw back to inefficient R&D. Rational design of novel synthetically accessible ligands is a far better way to go, not to mention novel protein based drugs are quite promising as well.
 
Don't worry, we all go off on tangents. Mine: The Green Collar Comedy Tour! (see earlier post)


You might be an Earthling if...
Your stellar navigation is based on two-dimensional images as seen from your planet's surface. What is "Orion" again?

You might be an Earthling if...
You think "parsec" is a measure of time.

You might be an Earthling if...
You think "light-year" is a measure of time.

You might be an Earthling if...
Your rocket technology is mostly aimed at other places on the surface.

And you might be an Earthling if.... ?
 
....hang out on a science fiction internet forum but don't think we should explore space.

Seriously, I've encountered people here with that attitude. I can't fathom it.
 
Let's face it guys. There is no tangible evidence that intelligent life exists outside this planet. I will say that given the sheer number of stars in this galaxy and the sheer number of galaxies in the universe that the odds favor life evolving elsewhere. But there's really no way to prove it one way or the other at this time. Or if it would even be anything like us. Just imagine what an evolutionary advantage we humans have, possessing interposable thumbs for example. To say nothing of how differently intelligent beings evolving under different circumstances would view the world as opposed to us.

This is a rather circular debate to have. If there are aliens out there, then how come only rednecks and scifi fanatics see them? :P

The laws of mathematics and statistics say there must be much alien life out there.

And the laws of physics say they pretty much can damn well stay out there.

While the laws of common sense say they'd have no reason to come here when they don't know there's a here to come to...

I think the real reason we haven't seen any proof of aliens is going to be much more interesting than either of those statements.

Um, I doubt it. Really, I doubt it. Space is just *so* damn big, you see, that that damn lightspeed limit buggers everything up...
 
Mind you, I've always said that if we ever do find proof of intelligent aliens, it'll be in the form of signal spam actually just passing by us on the way somewhere else. And possibly actual spam: "I am Emperor GHajhkhsfs of the Kuhiuiuhiuh system. My late father was killed when our sun went nova, and I need your help to unlock the 50 gajillion credits in his Galactibank account..."
 
^The same way you move anything: Leverage, torque and the appropriate application of force.

I'm sure if aliens did visit, they would have had better things to do with their time than move rocks around for the crazy bald ape people.

This single inconvenient truth causes more anguish to science fiction fans and alien watchers than anything else.

Yep.

^lots of people and physics.

How did they beat the gravity and friction force?

^The same way you move anything: Leverage, torque and the appropriate application of force.

Yep. This isn't rocket science, Starbrow, and we know it to have been fully within the capabilities of ancient peoples in many places around the world - which is why the dimwits on TV insisting that it constitutes evidence of high technology reveal themselves to be idiots or charlatans.
