Universe doesn't look real. Amazing picture.

[Berserker]

^^ No universe as he said neuron connections so in the brain it would be about 100 billion x 100 billion

OK, so neither of us were correct then.

Taking the numbers stated:

10,000,000,000,000,000 connections (max)
20,000,000,000,000,000,000,000 observable stars (maybe)
100,000,000,000,000,000,000,000 planets (very maybe)

So at least six, and more likely seven or eight orders of magnitude more stars then.

There are over 100 billion galaxies not a very low "100,000 galaxies" with a average of over 100 billion stars in each.

How do you define one galaxy from the next?

That's not hard - a galaxy is pretty well defined actually. You'll note in the galaxy pictures posted there's a lot of comparitively near-emptyness between the galaxies shown. There is not a uniform mass of stars throughout the universe.

Space inbetween them with very little, probably nothing inbetween

Just look at the original picture in the thread each one of those is a galaxy.
In effect just a cluster of stars.

Bugger Ive just found out Pluto isnt termed a planet anymore - where the **** have I been (well not on Pluto for a start)...

As to whether there is intelligent life, that's a completely different problem.

Eh, why?! With the astronomical number of different species there must, statistically, be out there on those countless planets, then why should some of them being intelligent be so hard to imagine?

yeah, they have to rewrite textbooks lol.

You have to look at this in four dimensions rather than three! There may well be/have been an alien race of similar technological development to us at some point in the future/past, but whether one exists right now is an entirely different question.

Civilisations on Earth have only existed for a few millennia, whereas the universe has been around for billions of years. It stands to reason therefore, that any life out there is/was/will be far more likely either not to exist yet, be incredibly primitive (bacterial most likely) or have become extinct a long time ago.

 

[Berserker]

What he said, plus assuming we ever find anything, unless it's very near by there's a good chance it's extinct already.

PS - I never said I couldn't imagine it, because I can (I prefer to think we're very far from being alone), it's proving it that's the problem.

Does anyone else get "We'll be back shortly/out of service" page?

Hold your spacewagons son, I didn't say anything about "similar technological development to us". I just said intelligent, which in this context is another way of saying sentient.

Obviously some of the species that were intelligent before us no longer exist, and some of the non-sentient ones at the moment will become sentient as times goes by, and so on and so forth...but that's not pertinent. My point is simply this: at this moment in time there are at least millions of species out there, and some of them are bound to be sentient.

OK fine, but intelligence and sentience are very different from eachother

I hope we're not alone.

I know we are


Whats that purple blob in the bottom left

Microsoft Sam says that the chances of being alone are unbelievably small.

Even rough math will tell you that there are billions of solar systems like ours out there, and one of the planets only has to be a certain distance from the star (depending on the star's size etc) for the chance of life.

He also said that the universe is expanding, and overall galaxies are moving further away from each other.

Think of it this way, take a balloon and inflate it by about 10%. Draw some dots over it with a black marker. Fill the balloon to capacity and watch the dots. The space between them gets larger and they move away.

Some people theorise that the universe's mavity will begin to slow down the expansion, and that it may begin to collapse back in on itself, into a big crunch.
