Extraterrestrial life

[Distracted]

Haven't seen a thread like this for a while.

 

Okay, do you think there is another life form somewhere in this (or maybe even another) universe, or do you think we're alone? Do you believe that UFO's are actually flown by extraterrestrials? What about crop circles? And alien abductions? Etcetera.

 

Just anything about extraterrestrial life. Let me start off by saying I do believe that there is another life form somewhere but I doubt they fly past in UFO's for no apparent reason. I also don't believe that aliens abduct people.

Your opinions?

[Aliath]

There's definitely life somewhere else in the Universe. But probably not what you imagine. See, it could be a totally different kind of life which adapted itself to conditions immensely different from that of Earth.

[Alg]

Universe is a big place. Probably more likely than not there's other life out there, I mean, earth life had to come from somewhere. There is one theory that states that earth life came from bacteria that hitched a ride on a comet, at any rate. And there's also one where amino acids were created on earth by whatever early earth conditions there were. In which case, chances are those conditions existed elsewhere.

I find it hard to believe that there isn't some form of life elsewhere in the universe. In fact, I bet there is sentient life as well.

The Universe is infinite. There could be hundreds of billions of other planets just like ours, with humans. I'm not saying they're anywhere close, or that we'll ever even comprehend how far they are from us.

 

The Universe is so freaking infinite that there could be hundreds of billions of planets with giant walking, talking bears. I'm not being sarcastic. Seriously, think about it.

[Distracted]

Well, I think most here agree there must be life somewhere in the universe. But do you think we'll ever interact? Would that be peacefully or bloody?

Probably not. Unless there are sentient life-forms that have reached an era where they can travel faster than light.

 

edit: light, not life. Sorry.

Umm, I said that there was life. Reread my post. :???:

No, i don't believe in the multiverse theory. With galaxies etc. possibly having initially started with more-than-lightspeed energy, this universe could be limitless. 10^58m, which is the size of the observable universe, is still quite big - it doesn't matter much either way; statistical probablilities are so high in the favour of some life somewhere, that life probably exists in some form or other many places. Intelligent life? who knows.

 

Do you believe that UFO's are actually flown by extraterrestrials?

 

We may all be extraterrestrials in the definition of the word. Who knows if life originated on earth, or was seeded from a meteor? But no, the common UFO story is absurd. It's so unlikely in terms of the length of civilization, the need for technology, the want for secrecy, the benign nature of these aliens and so on. survival of the fittest is not a theory limited to the earth: why would these super-civilized aliens not take over our planet and enslave us? Answer: they haven't been here yet.

 

What about crop circles? No. as likely as magic.

 

And alien abductions? No. as likely as magic.

 

Etcetera. I seriously believe the likelyhood of finding life on mars, Europa or several other places in our own solar system. with civilization having existed, say 20 000 years, the billions of years predating that make anything complex far fetched, but a silisium, not carbon-based organism would be an amazing breakthrough to find.

 

Is it worth spending resources on at this point in time? I think we have more important global challenges to fix before looking further.

Hehe, a common misconception. I will prove to you that the universe is not infinite by use of Olber's paradox, and Enstein's solution: The sky is dark at night. The universe is not static. The universe has a limited age.

 

explanation: if the universe WAS infinite, the sky would be infinitely light as there are infinitely many stars in any given direction. With this infinity, supernovae would cover the nightsky completely at all times. The sky is dark, so the universe must be finite.

 

The universe is not static. An infinite universe could not expand. Due to the redshift observed when examining distant objects in the night sky, we know the universe expands, the universe is therefore not infinite. This relation is quantified by Hubble's law.

 

The universe has a limited age. That's not entirely true: we don't know what happened in the early stages of, or before the big bang. Due to the fact that we know the universe exapands, we can regress the expansion backwards: something must have started the expansion. True to expectance, if we go 13,4 billion years back, everything was gathered in a single point.

 

This final assertion leads to another common misconception: this single point which was then the universe, is just as big as the universe is today. Many people ask " what's beyond that then". The concept "beyond the universe" doesn't exist, it's not possible. Knowing this singularity existed, which is does, because the universe expands, we know that all "planets" or other objects we can ever see are limited to the age since the last big bang, traveling just less than the speed of light consistently since then. The speed of light is a physical speed limit: we can never know if something faster than the speed of light exists, just as anything beyond the speed of light can never know if something is slower than the speed of light. They wouldn't even know of light as a concept. It is impossible to breech the speed of light. We don't know if something is above this limit, but if it is, it will remain that way for eternity, and will not resemble anything we know of today.

 

 

All that aside, the universe very very large, not infinite. That doesn't take away from the trillions of quadrillions of stars that probably exist though :D

If you think about it if it is that infinite someone on an entirely different planet looking exactly the same as you and in the exact same conditions could be doing the exact same thing right now..........

Ahh. It just seemed like you were trying to convince me that there was life.

 

:P

 

 

@321

 

Yes, it would be possible.

 

But those odds would be astronomical.

That's a good point! And in my opinion, it's very probable. :)

 

As for Earth being the beginning of life, that's ridiculous (respectfully)! The Universe is infinite in both time and space, in my opinion. I'm pretty sure there have been cases of life on other planets long before Earth. xD

Easy to say, hard to think about.

1. Eat Discovery channel

2. Eat 7th grade science teacher

3. Eat an article from Popular Science from the 1980's

4. Vomit

 

Lulz... I feel clever. I think there is life somewhere else in the universe. It's pretty [bleep]ing big and it's only getting bigger :/ I dunno... If there is life elsewhere, it's probably nothing like what we've ever seen.

I'm probably wrong. The Universe probably did start existing at some point. But like, that was probably a very long time ago. Very long time.

Earth is the center of the Universe, and we are the only living creatures because God said so. End of discussion.

 

On a more serious note, I believe there is other life in the Universe. As far as we know, life could possibly form very easily; perhaps right after the right chemicals meet during the right conditions, maybe not for long or very stable, but I think it is very possible. Our Universe is near infinite, with hundreds of billions of Galaxies, which have hundreds of billions of Stars, which on average each star could have say, 5 planets. The possibilities are endless, it could range from simple microscopic organisms to advanced sentient Silicon based lifeforms.

Yup. Even small chances of life in our galaxy. :)

So what are you saying; that it isn't random? That it's somehow predestined?

This isn't a debate, at least I think. As far as I know, we're all just throwing around random speculations and gazing outside our windows in wonder. :)

It's not hard to think about at all, because it's wrong, and the proof is staring right back at us every living moment of every day (and on page 1 of this topic).

actually, I was hoping that the otherwise science proficient community would consider scienfitic astrophysics points that they didn't neccessarily know before reading the topic, and realize that some things are very certain, and not speculations at all. Some of the things thrown out are proven to be wrong, so this topic may broaden horizons for many.

Uhm, okay. Thanks for the mature response. Just as I thought something intelligent was being typed by you.

This isn't a 'diss-religion' topic. People have the right to believe in whatever the hell they want without being mocked.
