alien life possibility is pathetic

So that possibility you find acceptable, but a similar assertion as to the possibility of an unknown (perhaps inelegant) species living in the any of the incredibly vast regions of the universe is not acceptable to you?

Wow, you must be a lot better at this observation thing than most people. Do me a favor? Here are some galaxies for you to observe. Could you please let us know which ones are deadly, which ones are habitable, and the reasons for your answers?

Thanks.

Jeez leweez, all uninhabitable galaxies! Where do i start?

Many of those galaxies lack metalicity, which would allow life to start, and are irregular or elliptical, which is dangerous to complex life.

How does a galaxy having low metallicity preclude a solar system existing somewhere in that galaxy that might contain life sustaining planets?

I cannot work out how such a conclusion could be drawn?

Surely at best you might say overall there is perhaps a lower probability of life occurring in galaxies with lower metallicity, but bearing in mind the number and variety of different stars within a single galaxy i would have thought even that would be pushing it.

And how do you know complex or irregular galaxies are dangerous to any sort of life? All the rare earth hypothesis proposes is that a star is in a stable area for long enough for life to evolve. Why is this impossible even in complex or irregular galaxies?
 
Uhm...

A barred spiral galaxy would not be as cozy to life as a spiral, wouldn't it? Too chaotic when compared with those nice and organized spirals, eh?

Educate yourself and stop being such a pretentious pr*ck? I think that would be a good start.

If the entirety of this thread was to back up some bigfoot support, you failed miserably. And further it alienated many of the posters here to your posts...

By making some baseless speculation and stating it as if it were fact, I expect.

I was right.

First, it's been pointed out that you don't know the current makeup of distant galaxies (what with how long it takes that light to reach us).

Second, how many heavier elements does it take to make a planet that can sustain life? Are you prepared to say that that much metal doesn't exist in ANY other galaxy but ours???

And why do you claim an irregular or elliptical galaxy is "dangerous to complex life"?

Do you realize our galaxy is one of the largest in the universe? What about the fact that the milky way is one of the oldest galaxies, and by far the most habitable, yet its shown to be incredibly unlikely to support other complex life

Do you realize that the Andromeda Galaxy is 2.5 million light years away? That's 2,500,000 light years. In other words, we are seeing our nearest neighbor as it looked 2,500,000 years ago. We really don't know what it looks like at this moment, because we have to wait another 2.5 million years to let the light from that galaxy get to us.

But let's do this experiment: if we travel back in time to see the Earth 2.5 million years ago, the first Homo Habilis appeared along with the ice age. (Source: http://math.ucr.edu/home/baez/timeline.html)

Now keep in mind this is our nearest neighboring galaxy. Even if you can determine the metallicity of a whole galaxy just by looking at it's picture (which sounds like woo to me, by the way), you are looking at an image that is old - not as it is now, and much older than 2.5 million years.

I'm still calling Shenanigans on you.

Please cite your references. And "www.outofthinair.com" (not a real URL) doesn't count.

Just making stuff up now?

By the way, did you ever take my advice and spend some time identifying galaxies at the Galaxy Zoo? Really, put in a half an hour or so, and tell me if you're still so confident claiming certain knowledge about ALL the rest of the galaxies in the universe.

Also, you've yet to acknowledge that as you observe objects further away from us, you're only seeing light that left there long ago. There's no reason to think that the Milky Way is older than other galaxies. However, when you observe other galaxies, you can only see how they existed long ago.

You haven't rebutted this point, nor have you even acknowledged it. What's the deal? Just covering you ears and saying, "La-la-la I can't hear you!"?

Thank you for answering.

In the post following that, I picked out a single star to focus on. Could you please tell me whether that star is capable of having a solar system that could sustain life? Thanks.
