I'm afraid that doesn't leave me any wiser. If something happened to cause the Big Bang, which created time and space, then it must have happened outside of time and space?? So, where did it happen and what is it that can exist outside of time and space?

If it created space itself and if as the theory states, space at the beggining was less than the size of a pinhead but has since expended, then since ALL space was at the point of creation, it happened EVERYWHERE, I know, that's a lot of "if's."

Yet all the stuff I have read suggests that the universe is 14 billion years old, that is it had a start point 14 billion years ago. Does that not contradict the idea that it always was?....

Yes (sort of) and when Einstein proposed it, it upset most of the physisists of the time and they rejected it for some time.

I only say "sort of" because IF it also created "time" along with the universe, then there was no such thing as "before'" therefore, the universe "always was."

I'd say it existed in a state that doesnt allow us to measure time through light. Something created light. But what.........;)

Light itself is nothing more than an electro-magnetic wave. Therefore it would have been created along wih electricity whech as I stated earlier, depends on the existance of matter: atoms, to allow electron transfer. In reality is the "speed of light" (and the speed of electricity) is the speed of electron orbit around the nucleus.

Quite recent theories state that the big bang was a "phase change" in the 'stuff of the universe'. Like liquid water and ice (same stuff but different phase)...

I understand that concept to be a recent way to explain the theory rather any actual change in the theory itself.

My theory says that the big bang was a result OF a phase change But quite far down the line.

Why do folk never mention sound in any of these theories? Light is direct energy, sound is indirect. Sound can do so much to affect the physical universe and yet it never gets a mention. Things need combining in a certain order in order to produce results.

AxN, P, M, Sound, Light ( here the measurement of time can begin) , F, Q

Quite recent theories state that the big bang was a "phase change" in the 'stuff of the universe'. Like liquid water and ice (same stuff but different phase).

Good stuff guys, if we continue like this we are bound to find the ultimate question of life the universe and everything (of course we all know the answer to that question is 42) ;)

And how does one create electricity? ;)

Actually, even now, "cold" does NOT exist; there is heat, and then there is the absense of heat. Cols is just a word to describe a condition that is devoid of heat.

& heat is just a word too. Heat & the absence of heat are 2 conditions that exist seperately. We call that which has little or no heat, cold & that which posseses heat, hot. If everything was hot then cold would not exist & vice versa. :p

But what is the size of a pinhead relative to? ourselves? Back to the marble thing again. How big would that pinhead be then? 10% of our galaxy? :)

If it created space itself and if as the theory states, space at the beggining was less than the size of a pinhead but has since expended, then since ALL space was at the point of creation, it happened EVERYWHERE, I know, that's a lot of "if's."

Aye, the existence of one defines the other, without which there can be neither :)

Agreed that we can discuss whether this is something new or an update, but it does in some way tackle the discussion of what comes before the universe as we know it (the answer being the universe as we do not know it :))

"heat" is energy. It requires matter. Cold does not. It requires "nothing."

Just because something is infinite doesn't mean it can't be bigger - it's logical to say "infinity +1" - welcome to the idea of the infinite hotel:

Yep. There are many infinities (don't mind saying that it took me a while to get my head around!), but it's easy to explain by example as the video shows. Another way to picture it - how many even numbers are there? Well you can keep counting in twos forever right? 2, 4, 6, 8... and so on, the list never stops. So there must be an infinite number of even numbers. But there are definitely more integers than there are even numbers, so the infinite number of integers is bigger than the infinite number of even numbers. Weird. I think I like the turtles idea better. :)
