space is not infinate, what we believe to space is.

If we were not so small and had the means we could travel to the end, where we would bump into a black wall with white dots on, while some form of life was looking in on us laughing at his little experiment.

We could even be in the corner of his dark loft, I mean humans say what space and distance are afterall, well all forms of measurments.

We could be smaller than atoms and 10,000 miles could be 1mm

Space now theres a question

 

But if you think of the leaps and bounds we have made in such a short amount of time its not inconcievable for us to come up with some sort of mass inter-stellar travel...

Think what someone in the 1800's would of thought if you said we'd have some one prancing around on that big white round thing in the sky within 150 years or that you could fit beethovens entire collection thousands of times over on a device that fits into your pocket...

probably of been hung for being a witch!

 

I always liked the though of that, though the life form looking in on us could have one looking in on them and so on and so on!

Think for that possible, our 'universe' would need to be the size of an atom for this being, or smaller...

 

I bet Clarkson has the answer
BTW this thread is far too deep for a Friday afternoon!

 

Far too deep for NSR you mean! First thread i've seen for ages that hasent been trolled and doesnt have pics of women in!

 

And theres a thing global warming!!

Millions of years ago, what are now the poles were deserts, the Uk was under water and near the equator, after rising from the mantal.

The planet has and is always on the move, the plates slowly move and what are land masses now, will again be see bed only to be pushed under the mantal, melt into the magma and resurface another 100 millions year later.

All the scientist know that climate and see levels, land levels, have changed over the millennnia, in all cases like the story of the UK.

At some stage in the future the plates will have moved over one another, everything we have built will have been forced below the mantal, regenerating as magma, climate will of destroyed us if weapons have not by then.

And in another 10 million years, just maybe something will emerge from a gene pool. Evolve into something that thought it was the first inteligent thing to live on this wonderfull planet. and start to build

 

A physical variation on the "turtles all the way down" view of god!

This seems somewhat appropriate to the thread:

hmmm, not sure what to make of that! think friday afternoon syndrome is setting in

 

If I remember correctly Olly, I think the scientists have got up to about 11 dimensions so far! It was in an article I read but can't remember where now. The membrane theory was all part of that.

Its a fascinating subject which throws up countless theories but no definite proof so far.

TonyG,

With this "Big Bang" theory, at the very beginning, before the bang that you mentioned, what was at the point of the bang, and where did it come from. Our rules of physics say matter cannot be created nor destroyed so the matter which was at the start of it all must have an interesting origin! But what?

Large numbers of dimensions have been hypothesised, this is a step forward in that a test has been proposed to test for a 4th spatial dimension. If the tests confirm the hypothesis then that will be a big step forward.

Most aren't even theories, merely hypotheses, they are not currently testable.

Energy and matter cannot be destroyed, but they can be converted from one to the other. I have no problem with a non-matter universe pre-existing this one.

 

This is where contemporary Christian leaders find a place for God and defer to science with regards an allegorical Genesis. Not my beliefs; just adding to the mix.

 

I'd have to say I don't know what was there before the bang, other than to describe it as a singularity. Where it came from is anybody's guess, but (if we are in a closed universe) ,it could have resulted from a "Big Crunch". Our physics can't yet get back far enough to give a decent theory - anything before about 10 to the power -27 seconds after the bang is a complete mystery.

 

According to one theory that is what happened ie a big crunch. This is a process which can happen over and over again, the universe expands in all directions until the galaxies run out of momentum and then everything encloses in on itself. However there must be a start point somewhere, does this theory assume that all the matter within the universe was present within this singularity the size of an atom! Or that after the big bang chemical reactions took place to create all this extra mass and energy. Or as Einstein himself proved did energy metamorphosise into mass! This would explain all the matter coming seemingly from nowhere. If mass and energy are interchangeable under the right circumstances does this mean we have an endless supply of energy around us! I echo the comments regarding the insignificance of humanity and the earth in a universal (should that be 'an universal! ') context. Also given this abundance of space around us why does my wife moan about the need for extra wardrobe space!

 

That's bollox .

If there are other worlds out there do you think there might be one where Scotland are good at football .

 

I think we should accept Douglas Adams explanation:

It is known that there is an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the universe can be said to be zero. From this it follows that the population of the universe is also zero, and that any people you may meet from time to time are merely the product of a deranged imagination.

So you lot are (and by definition myself) just the products of my (and your own) deranged imagination(s)

 

Hmmm part of that makes sense, infinite amount of space = infinite amount of worlds, and because not all of those worlds can support life the number of planets that have life must be less that infinite...

 

It has not conclusively been proven that space is infinite though. Our universe is finite therefore we cannot assume space is infinite. Thus we are working with whole numbers if this is the case. The numbers being so large just on the basis of probability there should be some other life supporting planet out there...Shouldn't there?

 

See what your saying, but if space is pretty much nothing..what could there bee other than nothing??? shurely there could be no end to space, because there would always be more 'nothing' ahead..?

 

Hmmm don't know, but space cannot exist on it's own without there being something to occupy it can it? Otherwise why is it there? Our space only came into existence after the big bang from a supposed singularity so it is not infinite thus there is an end to space but what lies beyond? And don't call me Shirley!

 

The most interesting question is what is the origin of the singularity?
