alien life possibility is pathetic

No this is actually a popular but wrong idea.

When astronomer speak of size of the universe, they are speaking of the size of the OBSERVABLE universe. Which is different to the size of the universe itself, for which as I said above we have only recent experience for a "closed" form universe which would be at least (ETA:) 80 billion light years diameter (as wiki says).

Just like when astrophysiker speaks of metal, they speaks of anything beyond He.

You seem to accept those crazy "scientists" at their word.

And yet...

We know for an absolute fact that life can exists in this Universe, and we'd be extremely stupid and arrogant to think that we were in some way special. The number of stars that could support life is literally astronomical! We've located other solar systems, including one with an Earth-like planet.

If you're wondering why we haven't found more Earth-like planets, it's because they're hard to detect, and the observations take a long time. For instance, the techniques we use would have a very hard time detecting the Earth itself, because the gas giant planets would dominate the signals we look for in these systems. However, new techniques are being developed, and results are expected in the next few years.

I say all this as a mainstream scientist, an astrophysicist in fact, and know of nobody in my field who laughs at the idea.

...somehow that seems completely lost on you. :boggled:
 
Drudge, why is it that people feel large #'s guarantee life? Insert the neccessary factors, and the huge numbers turn into microscopic improbabilities

None of us...

Let me repeat that...

NONE OF US have said there's a guarantee of otherworldly life. In case you haven't noticed, this is a skeptic's forum. We don't make blanket guarantees without provable data, and there's no evidence one way or the other. Just theories.

However, what you're arguing is the belief there's no POSSIBILITY of intelligent life outside of our own, and that's an assumption we can't begin to claim there's enough evidence of to be considered a valid conclusion.
 
Drudge, of course we do. The factors that i listed arent payed any attention. Most people say you dont need this and that, but the truth is that these factors have to be met for even life to start.

Which necessary factors would those be? You keep mentioning factors which aren't necessary or at best are not known to be necessary for life.

They are, but only to call you on your baseless assertions.

And you know this because... ?

This should be fun.

Please Mister expert on the universe...

Name ALL the factors that HAVE to be met for LIFE to start.

Which you base on one book which doesn't say so as emphatically as you claim it does.

Meanwhile you make up things like 90% of this forum would agree with you and that all real scientists support your theory (including the magician this place is named after who has never said any such thing, but who you consider a scientist who agrees with you) while ignoring the astrophysicist who tells you directly you're full of crap.

You still haven't convinced me you so much as know what a "fact" is, much less that your opinion on this matter has taken a single one into consideration.
 
Is it even possible to state THERE IS NO other life in the entire universe without combing every planet, moon, rock and whatever floats around out there?

As opposed to stating that other life is POSSIBLE.

No, desert, i am not a troll. I havent fell into the ongoing modern belief that alien life is a certainty,

Has anyone on this thread stated that?

It cant be near any super novas, has to have the right sun (sorry, red dwarfs wont cut it),

Even assuming it has to have a yellow dwarf sun (and there's no reason to assume that), there are billions of those in the universe

There's another one of your unsupported assumptions. But even if true, spiral galaxies are extremely common.

This is a claim you've made twice now without supporting it.

stable axis, magnetic field, plate tectonics, i can go all day naming neccessary factors.

Making up necessary factors, you mean. And guess what, several of the planets in our own solar system meet all of those made up requirements.

Again, no one is claiming extraterrestrial life is a certainty. But there is no reason to rule it out, or even to assume it is rare.

This is completely wrong. You really need to do some basic research if you want to discuss this intelligently.
 
Godless, several support that, but not one other than earth show evidence of even the capability or possibility of supporting simple life

Is it too late to ask if you know about the Drake Equation? By know, I mean prior to posting here, not a quick Google to Wiki. :boggled:

Nonsense. The leading theories for explaining the early Universe(e.g. inflation) REQUIRES that the Universe is much larger than the observable Universe.
 
Soylent, but where is this universe expanding into? Nothing. Thats all it is, nothing, no life, just us and a waste of space
