Logically why the universe cannot be infinite in size.

[SlimTrae]

Ok this a problem for the more curious amongst you Punisher etc but it is always said that the universe is infinite in size.

I however disagree with this as being scientifically impossible and I'm wondering who agrees with me?

If we believe the scientific model that the universe started from a Big Bang, then literally at the beginnning there was nothing. Now when the universe exploded into existence it began to expand according to science.

Now here's my problem. If something starts from somewhere, i.e has a beginning it can never be infinite in size or any other way, just not possible.

You cannot expand yourself to infinity because you'd never get there. By expanding you'll always be bigger than you were before but not as big as you are soon going to be, kind of like Bigaru or Boxing Gorilla :P


Anyways imagine it with numbers, if you start at 1 you cannot ever get to infinity by adding numbers because there will always be a higher number out there.

If the universe started from a tiny fixed point and has expanded ever since it cannot be infinite in size. If you could trace it back 15 billion or so years to the beginning (according to science) and it would be so small you could hold it on an eye of a needle then how can it be infinite in size now?

Not possible, it's just very very very very fucking big but not infinite.




Thankyou.

BUMP! Not sure if this poster is still here, But I dig the topic!

Where I would question is this partial statement: If something starts from somewhere, i.e has a beginning it can never be infinite in size

I disagree. Having a beginning isn't synonymous with having an ending. So for those who feel the universe will one day tear/rip apart or contract after expanding--they could say there is no Infinite universe. Simply because they hypothesize an ending.

However if the universe expands from any point (and never cease in motion) that right there IMO is a pretty good definition of infinity. In other words it isnt the size of the univere as much as its activity: its moving in all directions & accelerating at that!

Infinity: a number greater than any assignable quantity or countable number.

Since we have no system of assigning an end goal, point or fixture of our existence in the universe contained in something we call space. Space itself is infinite and will continue its journey of creating a place where any existing form of matter no matter how intelligent it becomes--will never reach that fixture- cause it is ever expanding!

Its just another Bilbo argument. Bilbo, you have no way of knowing how large the universe is so your suggestion is faulty.

I realise I have no way of knowing how big it is but logically it cannot be infinite can it?

If it started from a single point, and both science and religion agree that it did then how can it be infinite?

If you start at 1 and begin counting you will NEVER get to infinity will you. Why is this any different? You start from an atom (actually smaller) sized but rapidly expanding universe, it's always getting bigger.

If it's getting bigger it CANNOT be infinite.

Simple logic my Korean friend.

Againm my question deals specifically with certain sentences and not the entire post, I quote: If you start at 1 and begin counting you will NEVER get to infinity will you.

I see the same thing from a different perspective. I would word it like this: If you start at 1 and begin counting you will NEVER get to infinity because infinity has no end point.
