aliens and astronomy

[LDG519]

Any of you watch the news in the past month?

Earth-like planet found around Gliese. Can't remember if it was b, c or d. The planet is much closer to it's star than Earth is to Sol, though Gliese is a red dwarf, so the 'Goldilocks Zone' therefore, is much closer than ours would be.

Sad considering the star is close to death, since it's already been through the red giant phase, by the time we achieve space flight (if...), the star would probably die, thus, the planet in question wouldn't be open to habitability.

I'm more interested in kepler 11, it has 6 earth like planets and I think some of them are in the goldilocks zone but I'm not sure

The Imperium. The Space Marines are soldiers within the empire known as the Imperium.

If you're going to do a stupid nerdy reference then at least do it right.

Correct title is The Imperium Of Man.

[Scraby]

If we are talking about our aggressivnes,if there are more sentinent species in space,then some of them might be tens or mabe thousands of times aggressive then humans...(*cough*like blowing a planet into infernos....*cough*)

[Wings of Fire]

And?

Fucking nerds.

[Mr. Bungle]

Beat 'em up and steal their lunch money.

[Nate]

Wait, Scraby says there are life forms. Ah ok, let's tell the scientists to cancel their research, we have a verdict.

Don't be stupid, Scrabtrapman. All mainstream scientists with a good knowledge of Evolution, Cosmology and basic Statistics will agree that there is almost definitely life in other solar systems.

For example:

[Scraby]

strange,if we were alone in the universe,how come that we came into existance if there is nobody for trillions of light years,that would be strange,cuz if there wasnt a planet with life busted,the bacteria would have never came to earth...

[Nate]

Uhhh... why can't the bacteria have evolved on Earth?


If you're suggesting that bacteria has to come from somewhere; where did it first come from?

[enchilado]

THE MOON

[STM]

It had to evolve...it can't just keep appearing, it involves millions of years of evolution from amino acids to RNA to DNA to complex single cellular life that protects the DNA increasing survival and therefore bacteria species radiation.

[Scraby]

I know that,but lots of them say that asteroids brought life to earth.Its not necceceraly correct but who knows,unless you have a time machine.

[Bullet Magnet]

There are ways to determine it without needing a time machine, though it is difficult. While you can't really disprove panspermia, one way to demonstrate it's truth (if it is true) is to find an asteroid or comet or other fragment bearing life or proto-life that is basal to all life on Earth (ie, once establishing it's relation to Earth life, ruling out the possibility that it originated here).

Panspermia, while unproven, is a legitimate hypothesis as a part of the history of life on (and off) Earth, but it is not a solution to the origin of life itself.

[STM]

But do asteroids really contain life? Unlikely seeing as an asteroid can't hold heat, gravity or an atmosphere. Any life we found on an asteroid would be dead from intense freezing or burnt in the collision with our atmosphere.

[Scraby]

the bacteria are frozen in a deep sleep for thousands of years till they hit warmer land,then they start awakening,eating and finaly reproducing

[STM]

Aye? This isn't Doctor Who.

[Bullet Magnet]

Asteroids and like fragments are not nearly as hostile as some Earth environments in which life can thrive. And these extremophiles are often of the most basal strain of life, not even bacteria, but of the domain Archaea.

[STM]

But even Archaens (correct me if that's not right,) must do all the seven basic functions and they still have organic material that would not survive plummeting to Earth on an asteroid...even if the asteroid was large enough not to disintegrate into something the size of the a pebble, the meteorite would likely destroy all autochthonic life in impact.

[Scraby]

some say life is like a virus,it always adapts,mutates,and survives,many asteroids that fell,delivered bacteria that were frozen on them.Chondrites are the one type that deliver organic materials

[Dixanadu]

Yeah, Evolution was a pretty cool movie.

[Strike Witch]

Yeah, Evolution was a pretty cool movie.

I love the bit with the shotguns.

[Dixanadu]

I love the bit with the shotguns.

In the mall after they killed the dragon-spawn-loogie. Yeeeaahh.

Srsly though... I really hate narrow minded people who say 'No aliens exist'. They assume the word 'alien' means a grey thing that abducts people, despite the fact the term originates from the Latin (or was it Greek?) word 'Xeno' which, most of you will assume, means 'foreign' or 'stranger'.

But more or less, life somewhere in the galaxy, or/and the universe, must be teeming with life, be it animalistic or sentient. Only time will tell...

By the way...try checking out Alien Planet. It's a fictious documentary about finding life on an extrasolar planet. It's on YouTube, if you're interested.

[STM]

MEXICANS?

I think Darwin IV was a fantastic concept, Wayne Barlowe did a good job making his book so believable.

And I'm not saying there's no alien life, just that no alien life came from any meteorites, then again, ablation dictates that if the outer layers are stripped away and the innards are still cool, perhaps just maybe some extreme life form might survive the impact. But this would only work if the meteorite's resultant explosive impact didn't destroy everything in the vicinity.

[Scraby]

there are some bacteria that can survive tremendous heats,just like they found those worms that live underground where miners bearly survive,a perfect example is a cocroach,a nuke cant stop em,heat cant stop them,starving cant stop them,only the human foot can stop em...there are organic materials on asteroids and meteorites,go around wikipedia and search about it.

[STM]

Erm yes, a nuke will kill a cockroach, in fact a concentration just six times that of the human limit will kill most cockroaches this is because cells only become cancerous from radiation in division and cockroaches cells divide every few weeks when they molt, a world submerged in fallout would still have a terrible effect on our poor little insect friends. In further addition, as a living creature, they still require oxygen to survive and temperatures that don't exceed 150 degrees. Organic materials don't = life as well. There are organic compounds such as amino acids on Titan, (At least this is what scientists speculate) however Titan isn't too far off absolute zero the chances of life, at least on the surface, are small.

[Scraby]

an asteroid has a cold surface,but the inside of it doesnt have to be like that,there is water on asteroids equaling that there is O an that means that there might be life on asteroids,just like some planets that were slingshooted off of their star system.

[Wings of Fire]

And how would any part of an asteroid stay warm in deep space?

[STM]

I don't know just how that comes into the equation of things WoF but I suppose if you're just generally asking a hypothetical warm asteroid could get very close to the sun, or have a molten core through immense pressure but then, I would have thought that this was impossible for an 'asteroid.'

an asteroid has a cold surface,but the inside of it doesnt have to be like that,there is water on asteroids equaling that there is O an that means that there might be life on asteroids,just like some planets that were slingshooted off of their star system.

Where are you getting all this ground breaking information from? An asteroid is cold well done, as is the vast majority of the vacuum of space. So why would the inside be warmer? What would significantly warm up the inside of an asteroid? Remembering of course that most asteroids are no larger than a brick and only 1100 asteroids known to man in our solar system bigger than 30km in diameter. Also yes there are sometimes trace amount of water on some asteroids...we expect, that doesn't equate to life, otherwise there would be microbes on the moon and almost every other planet we know of. Firstly, yes having water does mean that there is oxygen but then it would be locked up in freezing cold ice...trace amounts of ice, we're talking a few bonded atoms here not puddles.

[Scraby]

they are warming up,thats why if a meteor is coming near earth or something bigger,you see a trail,if you use high tech telescopes you can see trails of water,that is melting from the meteors core.Meteors and asteroids that have water and carbon,from that with organic building materials life started to thrive.

[MeechMunchie]

If we ever develop a galactic empire, I'd like people to go round dropping 75 cokroaches on every uninhabited planet and see how long they survive. You could take bets! And then end up with a race of super-cockroach-people a few billion years later.
