    Yes, the Big Crunch, I should have capitalised.

    Why do you think the universe will continue to expand and then go into reverse? Is everything going to bounce off a wall and come back? :D

    Per Newton's first law there would need to be a force to first slow it down and then make it go into reverse, and what would that be?

    Gravity my good fellow, gravity.

    How was it compressed to a single point in the first place?

    In reality infinity is a mathematical concept not a physical one. So the age of the universe is not that relevant.

    In mathematics there’s different infinities. Countable and uncountable.

    He’s saying that the expansion due to the Big Bang will slow or stop and gravity will continue to exist as an attractive force and therefore the universe will contract.

    Perfectly sound in theory but the observations don’t show that the expansion is slowing, instead it is accelerating.

    I know that's what he's saying and I'm disagreeing with him because of what you're saying. :pac:

    If there was enough matter in the universe (regular and dark) it would never have started to accelerate. Which concludes we continue into the very far (but not infinite) future and the heat death of the universe. Don't worry, there's plenty of them around.

    They changed the meaning of a billion a few years ago too. In America it meant a thousand million. In the British isles it was a million million. Now the American definition is the official meaning in the British isles too.

    What confuses me is I remember this happening during my lifetime. In school I was taught a billion was a thousand million. I was sure this happened sometime in the late eighties or early nineties. But apparently the definition was changed in 1975, the year before I was born.

    Your original schoolbooks were probably first printed before you were born though :-p

    Still waiting, but this will happen today. It's a universal boards.ie constant. :D

    That’s not infinity, it’s undefined. It tend to infinity and the denominator gets smaller but it’s not defined at 0

    Apparently it's just a very big number,or all there is of something.

    Somebody should have sent out the memo on this as I like most folk have always assumed infinity was the former.
    Can anybody explain the concept in 60 characters or less?

    I'm sure she loved it, but keep a careful watch, necrophilia can be frowned upon.

    Reminds me of the same mistake I made in school.

    Anyway I was trying to work out what the AH reply was, not referencing any particular mother.

    Infinity. Which also means that you can’t divine infinity by infinity and get 1.

    It would need to have a limit to divide it by two.

    And apart from a few nerdy types we all know infinity is limitless

    If you had an infinite number of toilet rolls, and you rolled out the paper and laid it in a line, end to end, and also laid the cardboard tubes in a line end to end, then the paper line would be longer than the cardboard line, yet both are infinite .... how can one infinity be longer (bigger) than the other?

    If they're infinite they're endless,so one can't be longer than the other.

    But they clearly are .... So maybe infinity is just a very large number, and the number for paper is larger than cardboard....but both are "infinite"

    The literal definition of infinite is endless.

    The mathematicians however have decided off their own backs and without any consultation to have infinite as just a big number.

    Not to go off on a tangent, but at the risk of being obtuse, it would be a sine that you're mad if you did.

    Imagine a steel ball the size of Earth.

    Once every ten million years a fly alights on the ball.

    When that ball has worn away to nothing by friction from the fly - infinity hasn't even started yet.
