Intelligent Design

well it's always a trade off between how far you see and how well you can see isn't it?

This is the furthest we can currently see:

(click for fucking enormous version)
That's the Hubble Ultra Deep Field photo, or UDF. Even the tiny specks of light in that photo are other galaxies. The 'shutter' was opened for about 2 weeks I think. But the really staggering thing is that this little patch of sky is just 0.00002 degrees out of the full 360 degree sphere of visible space.

But we'll only ever see planets in our own galaxy, and even then the ones that are pretty close.
 
Fuck a doodly doo!! :eek: :cool:

<downloads pic>

So, really these new telescopes won't tell us much about whether there's intelligent life in the universe unless they actually find it cos they're still only seeing a teensy bit.
 
depends. hubble's good for these long-range, tight focus shots. We can also use a 'wideangle' telescope to do more general searching. We certainly won't be seeing their planet and their little cities or anything. But we will be able to see a blurry speck that has some very interesting chemicals in its atmosphere if it's filtering out those speceific wavelengths of light. When we find one of those, then we turn all the pencil-beam telescopes on it and look really carefully.

There are about 100,000,000,000 stars in this galaxy, and there are about 100,000,000,000 galaxies in the universe. We are small.

Aye, but as the photo shows - that's one fuckload of sky to search through . .
Yeah, but we wouldn't bother with looking that far away for life. We'd only be interested in looking at the nearby stars, and they're so much easier to see that we can scan the telescope across the sky and build up a complete picture pretty quickly.

It's still very much a 'local search for local aliens', though.

I think it's a very optimistic view you're taking that we'll find anything quite so close.

This is nothing more than a hunch, though,
 
It's a hunch both ways - it doesn't make any difference to anyone else if I reckon there's loads of aliens out there, so I may as well believe it if i makes me happy :)

Agreed.

It's just that I have conversations with some of my academic friends who regard me as a bit of a loonspud for my views on the likelihood of alien life and you're way more optimistic than me. :)
 
Hehe. I guess what I'm more certain about is that we should have the technology to know almost for sure whether there's life out there. The intelligence bit is just my optimism :)

Ah, I love it when a thread gets derailed onto Space!

The universe seems almost designed to demonstrate to us our own physical insignificance, does it not?
 
Realisation of species' insignificance --> abandonment of anthropocentrism --> acceptance of scientific materialism == atheism

Welcome dwyer. Some said you'd never make it :)

Geez it'l be a fucking lonely eternity if it turns out we're the only planet in the universe with life. Conjours images of a very small child standing alone in the middle of the pitch of a dark stadium.
 
Crispy said:
Well, the telescopes we'll be building over the next 20-40 years will be able to know for sure, and it's my personal belief that life is common enough for there to be some intelligent examples of it close enough to see.
But without any evidence of that, isn't that a bit of a big assumption to make? What makes you so sure that the conditions for the evolution of intelligent life occur even more than once in this galaxy?

Existential negatives are the default postion ;)
 
Fair enough.

You do know that it won't be the geeks who end up exploring new worlds and teaching alien women about this strange thing they call kissing anyway, right? :D

Exactly how powerful are these telescopes?

On a related note - there was some statistician who did a calculation based on a very optimistic picture of a universe relatively teeming with intelligent life and he posited that a lot of these aliens would be pretty well obsessed with 'visiting the neighbours' and had warp tech etc etc.

Because it would be a case of them visiting each other a lot as well (rather than all of them just wanting to pop round our gaff all the time), then even with aliens almost everywhere the gaps between visits would be pretty large.

Maybe the last ones to check in on us popped round and just nodded approvingly when they saw us beginning to bang the rocks together.


It's all random as you like and they aint all that at all. They think we are really clever for example. I have several anecdotes that show this to be correct. I suppose those same anecdotes would prove that there's aliens and that beyond reasonable doubt ?
We all know that it boils down to sharing the same physical space with the wronguns.
You can make your own minds up but they have enlightened this poster not a fucking tiny bit but just scorned his simplicity and that !
Ok!

But there is at least one instance. That means it's legitimate to look at how frequently the base conditions for that occurrence are likely to occur, given what we know about stellar evolution and the formation of planetary systems. There's about one hundred thousand millions of stars in our galaxy, so even if the chances of a (sufficiently) earth like planet are small, there would still be an awful lot of them.

And, crucially, there's no reason to believe the Solar System is so very unusual, so there's room for debate about the default position ...

Actually, to be picky, not all organisms are equally evolved, depending on how you choose to define it.

Those who have swifter reproductive cycles will have gone through substantially more generations, meaning that more evolution, in terms of random mutations under selective pressure, has taken place.

i was using it to mean being suited to ones enviroment due to the process of natural selection. than to say that this Fx generation is more evolved than the Fy generation as it has reproduced significantly more times



but yes i do accept there are multiple ways you can use the term
 
There is an argument based on Schrodinger's Cat that says that because it's sentient observation that orders quantum chaos, that unless an alien species had the same kind of sentience as us to create the 'same' universe we inhabit, even tho there might be aliens out there we couldn't see them, and they couldn't perceive us.

Of course, that whole road leads to the question of was the moment of creation a fluke quantum instant where 'a' sentience was achieved long enough to collapse the probability wave of the pre-universe (i.e. the everything-and-nothing potentiality of the pre-bang universe) into the physical realm we inhabit.

Or something. :D

On the subject Fogbat is talking about, there is at least one species of rodent that has a speedier reaction to environment changes.

The concept of being 'more evolved' would suggest that a species has undergone and survived greater environmental changes, meaning that it's abilities to adapt were better - in that respect the tool making facility of humans is a kind of evolutionary pinnacle because via tool use (a human universal trait) the human basic model can exist in a variety of environments from temperate to cold/hot to the vacuum of space. A species with greater levels of physical evolution might be able to survive in more extreme conditions without resorting to external tools. In that sense the creature could be described as 'more evolved', if you take inbuilt adaptation ability as the main marker of evolutionary development.

one principal baffling phenomenon for me from the school days was: why the evolution has stopped at the pinnacle of human life :

Don't be a fool. What makes you think we have stopped? It's a very very very slow process.
