Physcists? Alien life forms?

Question

Iam reading a breif history of time to try and understand how our little world came about.

Iam amazed to find the amount of galaxys stars ect out there,

do u think thes a planet somewhere with life on it ?

Answer 1

Definitely! And life doesn't mean just intelligent life like us humans! The range is from microorganisms to civilizations way ahead of us!

Answer 2

The best and only reasonable solution to the Fermi Paradox is that we are the ONLY show in the town... sorry kid. http://en.wikipedia.org/wiki/Fermi_parad...

But if you just HAVE to believe in ETs and UFOs, the antichrist has something special in store for you. Google/youtube: "Project Bluebeam"

Type III 'aliens' and fake 'messiahs' just in time for 2012! Many will be fooled...

Just do NOT accept this:

Later, ask yourself how we knew in advance:

Answer 3

Yes, there is, you're standing on it. (Ha Ha gotcha)

OK you mean a planet somewhere else with life on it... probably.

But you know what? Just like happened when the submersibles went to the ocean floor vents and found tube worms and a whole ecosystem living off of geothermal energy and what to most life is poisons, when Earthlings finally do find life on another planet, they will have to expand their notion of just what being alive is. Science is constantly having to do this. I believe it would boil down to something like this:

life is matter that is able to behave in ways unexplained by the laws of physics, particularly unpredictable non-random actions.

That's what the SETI looks for, non-random stuff. If it's neither random nor predictable by physics, it was sent by somebody.

Now the laws of physics and chemistry can predict what your cells will do more or less. But they can't say what you will decide to eat for breakfast.

Sometime in the past, some matter started acting different from other matter. And it kept on acting different from regular matter and now we call it living tissue, or organisms. Even viruses are alive cause they don't act like normal stuff, they are renegade RNA out roughing it in the extracellular world.

Basically on our world the first living things were (apparently) RNA-like collections of 4 different proteins. That those 4 proteins, and the RNA and DNA arrangements, worked out for life is a peculiar effect of the Earth's conditions. Somewhere else, maybe the basic building block of life will be some entirely different chemical. It may have nothing to do with proteins or amino acids, let alone RNA. Maybe on some hot volcanic world somewhere there is an ecosystem of life based on entirely different elements than carbon.

You hear the phrase "life as we know it" a lot, people asking if "life as we know it" exists elsewhere. That's not the interesting question, it's life-as-we-don't-know-it that will be the big discoveries. Just like the tube worms were. If all the submersibles had found were a few new species of fish, it wouldn't have mattered much.

I was heavily in the science end of things in college and my major was Math, but after graduating I steered into philosophy... maybe that's why I think scientists are barking up the wrong tree by just looking for Earth-like planets. All they'll find there is Earth-like life. Not as interesting a possibility life on a non-earthlike planet would be.
