Who's to say that they can't live through gamma rays? Who's to say they have to have the same tissue as humans? There can be other life-forms thatdo not need anything we do on Earth.
The Universe is really, really, really big. [PIC]

Exactly. You are assuming that everything has to be a carbon based organism like us. But that doesn't have to be the case. Hence making them immune tocertain things that are killer to us.

I know what Dr. Malcolm is saying
that's factored into the mathematics, only about 10% of solar systems are even remotely capable of creating life...as far as being immune to gamma rays...this isn't a cartoon.

I'd be interested to know what the basis of your mathematical theory is.

Since when did we decide the factors for the entire universe on what represents life and what doesn't?
We can barely see what's out there never mind actually getting to it.

Some basics so we can all start on some equal footing before arguing some more.

No need to worry about all this shh. Some dudes dedicate their lives to research and come out with a 0.00001% advancement
Just forget it... wait till they come to us.

The Drake equation doesn't really account for everything and there's a lot of debate as to what the variables actually are.
My mathematical/statistical basis is simply looking at all the infinite variables it took to create life here, the chances of those or similar conditions beingreplicated are literally incomprehensible.

1) Basic philosophical question: If the Universe is infinite, what does that (what you're saying above) all mean? We have 1 in infinity (existence of lifeon Earth). Can we have 2 in infinity?
2) Another: If replication is literally incomprehensible, is our existence also literally incomprehensible? And if it is, what does it mean for us to makefurther sense of what we can't make sense of in the first place (trying to find a 2nd based on the 1st when we don't yet understand the 1st)?

I said the variables for creating life are infinite, not that the Universe is infinite. It might be, I have no idea.
And yes, our existence is pretty much incomprehensible, no one can figure out just how many things had to occur in a perfect sequence to create life and thenintelligent life.
Really, you could go in circles all day about this stuff but at the end of the day I rest my hat on the even more overwhelming odds that there is nointelligent life out there and that even if there was it would be even less likely that there will ever be any contact made.

lol Word. And GodofWar.. you should consider writing a screenplay.. The Ultimate Greatest Story Ever Told.. Ultimate Jesus..
Lay off the DBZ there for awhile fam
Honestly though, the universe is SO COMPLETELY VAST, that the odds of life CAN NOT only be 1 in a trillion

The math means squat in the matter of it.
The same variables that created life here don't have to be the same to create life elsewhere in the Universe.
It's not that hard to comprehend that life isn't bound by our standards on earth.

[h1]Scientists discover a nearly Earth-sized planet[/h1]
- Buzz Up
By JENNIFER QUINN, Associated Press Writer Jennifer Quinn, Associated Press Writer - Tue Apr 21, 6:17 pm ET
HATFIELD, England - In the search for Earth-like planets, astronomers zeroed in Tuesday on two places that look awfully familiar to home. One is close to the right size. The other is in the right place. European researchers said they not only found the smallest exoplanet ever, called Gliese 581 e, but realized that a neighboring planet discovered earlier, Gliese 581 d, was in the prime habitable zone for potential life.
"The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'" said Michel Mayor, an astrophysicist at Geneva University in Switzerland.
An American expert called the discovery of the tiny planet "extraordinary."
Gliese 581 e is only 1.9 times the size of Earth - while previous planets found outside our solar system are closer to the size of massive Jupiter, which NASA says could swallow more than 1,000 Earths.
Gliese 581 e sits close to the nearest star, making it too hot to support life. Still, Mayor said its discovery in a solar system 20 1/2 light years away from Earth is a "good example that we are progressing in the detection of Earth-like planets."
Scientists also discovered that the orbit of planet Gliese 581 d, which was found in 2007, was located within the "habitable zone" - a region around a sun-like star that would allow water to be liquid on the planet's surface, Mayor said.
He spoke at a news conference Tuesday at the University of Hertfordshire during the European Week of Astronomy and Space Science.
Gliese 581 d is probably too large to be made only of rocky material, fellow astronomer and team member Stephane Udry said, adding it was possible the planet had a "large and deep" ocean.
"It is the first serious 'water-world' candidate," Udry said.
Mayor's main planet-hunting competitor, Geoff Marcy of the University of California, Berkeley, praised the find of Gliese 581 e as "the most exciting discovery" so far of exoplanets - planets outside our solar system.
"This discovery is absolutely extraordinary," Marcy told The Associated Press by e-mail, calling the discoveries a significant step in the search for Earth-like planets.
While Gliese 581 e is too hot for life "it shows that nature makes such small planets, probably in large numbers," Marcy commented. "Surely the galaxy contains tens of billions of planets like the small, Earth-mass one announced here."
Nearly 350 planets have been found outside our solar system, but so far nearly every one of them was found to be extremely unlikely to harbor life.
Most were too close or too far from their sun, making them too hot or too cold for life. Others were too big and likely to be uninhabitable gas giants like Jupiter. Those that are too small are highly difficult to detect in the first place.
Both Gliese 581 d and Gliese 581 e are located in constellation Libra and orbit around Gliese 581.
Like other planets circling that star - scientists have discovered four so far - Gliese 581 e was found using the European Southern Observatory's telescope in La Silla, Chile.
The telescope has a special instrument which splits light to find wobbles in different wavelengths. Those wobbles can reveal the existence of other worlds.
"It is great work and shows the potential of this detection method," said Lisa Kaltenegger, an astronomer at the Harvard-Smithsonian Center for Astrophysics.

well even though the universe is billions of years old. earth can be the only living inhabitant planet in the universe. have you thought about usbeing the first planet with life? maybe a few millions years from now another planet formed somewhere else with life like ours. remember theres a beginning toeverything. we can possibly the first planet but not the last.

I think infinity works all of these questions out. If our existence is the product of random events, then infinity-by definition, would have me think that ifthere aren't other forms out there like us, there will be infinite times in the future. That is what infinity does. It is like the infinite monkey theorem.Given an infinite amount of time, a monkey will type the complete works of Shakespeare an infinite amount of times.

Sure. The Universe might be some billions years old, but that's along the time dimension. What about space, isn't that infinite'*%%?Then what about space-time?
Anyways, I don't think we're arguing the same thing here.
infamousod, how do your equations change with news of findings of Earth-sized planets like in the article that dirty just posted? Anyways, all of this justseems like a fun mental exercise since our understanding of any of this is just way too preliminary (my opinion).

how do we know about the milky way if it takes billions of years to travel out of the galaxy to see it?

Well that planet defied a few dozen or a few thousand variables. Only a few more mil/bil/trillion to go to create life.

Well our mathematical equations are all for finding the probability that there is life out there that evolved in the same way or in similar waysto ours. So, the math is correct but we are defining what the probability tells wronglyOriginally Posted by swyftdahoe
Well, I wouldn't say there's no way. Anyways, what Dirty is alluding to is that maybe it's possible that aliens wouldn't be carbon-based (or needing to inhabit a planet with the same properties as Earth) and as such, all our mathematical guesses would be invalid.Originally Posted by Mez 0ne
My thoughts exactly.Originally Posted by Dirtylicious
but who is to say that the way life evolved on earth is the ONLY way that life could exist?.Originally Posted by infamousod
Ok I did some consulting and got some science to further support my mathematically-based theory of why it is extremely unlikely (nay impossible) that there is life somewhere else in the universe. Not only are there trillions (or more) of factors that need to be in perfect order but you can start eliminating most of the solar systems off the top. Any system within a galactic core is being bombarded by gamma radiation and therefore sterilizes anything within its reach. This accounts for about 80% of the stars.
FYI this solar system is on one of the outer bands of the Milky Way.
Add to that you can eliminate any system with binary, pulsar, and neutron stars too, among a few others. All of a sudden the pool for potentially life-sustaining stars is lowered dramatically. There still are countless other systems that may have the right conditions, but there are so many variables involved, that it's far from probable that there is intelligent life out there, and unfathomable that whatever is out there has made it to Earth and has been flying around.
..such hubris on the part of man.
There is no way that life only exists here, and here only.

Think about it. The universe can't go on forever. It has to stop sometime. And something had to create everything.

Why would you hope such a thing? Life on Earth is pretty mundane for most
Beyond the internal mental debate and the war of words and logic going on in here, this stuff is pretty trippy. And as intriguing as it is, there reallyisn't light at the end of the tunnel as far as answers are concerned.
