Do Aliens Exist?
Do Aliens Exist?
This is in the off-topic chat section, and continued from the discussion over here.
Microbes are possibly a key to everything, and all of these questions are going to get much more interesting and complex when we discover aliens. :)
literally bend space-time at will.Re: Josh: They quite possibly are. I don't see how aliens would play a part in it; if they evolved in a different solarsystem/planet, they are likely so completely different from us that their microbes wouldn't affect us. If they got over here, they would however have the technology to do whatever they wished to us practically instantly(ie; destroy the whole planet, cause a lethal plague, etc). This is because of the various limitations of space travel which make it so you would have to be able to
Have you heard of panspermia?
Panspermia is a hypothesis proposing that microscopic life forms that can survive the effects of space, such as extremophiles, become trapped in debris that is ejected into space after collisions between planets and small Solar System bodies that harbor life. Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks. If met with ideal conditions on a new planet's surfaces, the organisms become active and the process of evolution begins. Panspermia is not meant to address how life began, just the method that may cause its distribution in the Universe.
I really like the idea, though I don't know if it is true. Tardigrades can survive in space for at least ten days. Bacteria maybe longer.
I think that when we do encounter aliens it's going to be more like Andromeda Strain than Star Trek. I'm less inclined to believe that aliens fly around in spaceships and think and act like modern humans.
