heres an idea of how big space is if we sent a rocket ship towards the next closest sun traveling at the speed of light during the caveman time it still woudlnt be there yet.

Thnkx for the infos Waspie. I never knew it wasnt infinite..

Well I know is that to find the end of the space will take years which will feel like the space is infinite grin2.gif


Trying to find the end of the universe is like trying to find the end of the earth. If you go far enough you will arrive back where you started.

If you sent a spacecraft to the nearest sun at the speed of light (excluding our own) it would arrive in just over 4 years.

And your point is? If you just post a link without explaining what it is you are trying to say then you are just wasting your time.

  • Dying is a very dull, dreary affair. And my advice to you is to have nothing whatever to do with it.

Think about it, logically, its right to have an end for the start but, Space is infinite. Like, just keeps going. No end. No walls, just friggin space. Like going on and on and on and on.

Because of that fact, can we relate that to other things?? I mean if you think seriously about it, it really doesnt make any sense. Everytime we see something, we will be expecting for that "thing" to end anytime. How could Space not have an end?? Is it because the way we think?? The way we look at things? Is it something that we cant relate cuz its out of our hands?

What do you think?

Sorry if it sounds confusing...

** dam sorry for the spelling mistake in the title...  hmm.gif


Actually there are some scientists that say that universe does have an end...the thing is limitless not infinite...its like the sand, its imposible to count all the grains in it, but they have an end...

For someone with nothing to say you are making lot of posts.

Yes it is true that the standard model of the big bang is not proven, what is meant by that is the explanation of how the big bang came to be. There are several theories of how the universe began. They all have one thing in common... the universe was created at a specific moment in time and is expanding at a finite rate. There is very strong evidence for all of this, there is residule energy from the moment of the creation known as 3K radiation, also the expansion of the universe can be measured by the red shift of light from distant galaxies. All of which means that my original statement still stands... the universe has existed for a finite amount of time and has expanded at a finite rate and is, therefore finite.

The very post you have linked to is an alternative explantion for the big bang not an argument against it.

"It's a mathematically plausible model which refines the standard model of the Big Bang,"


In what way does it contradict the fact that the universe is finite? Yet again you have failed either to read or correctly understand a link yu have posted.

One caveat to my argument:

The univese is generally regarded to that which was created in the big bang. It is possible to theorise what lies beyond, but it may be impossible to know for sure. Hence it may be impossible for us to know if we are just one universe amongst many in a "multiverse". It is conceivable that the dimension or multiverse (call it what you will) that our universe is expanding into is infinite however the universe that we occupy will still be finite.

This depends on what you mean "has an end". It is rather like being on a sphere, there is a finite volume but you will never find the edge. The express used is finite but boundless.

However their is an "observable edge" to the universe. It is impossible to see further than 13 - 14 billion light years from earth. This is not because the universe ends there. Because light travels at a fixed finite speed if you try to look back further than 13-14 billion light years you are trying to look back to a time before the universe began. The actual universe is much larger than the observable universe.

The Big Bang= Begginning
The giant Freeze/Big Crunch = end

The besr current evidence suggest there will be no big crunch. As to the big freeze that will be when all activity stops in the universe, but the universe will still exist albeit as a uniform lifeless dark entity.
