Who collapsed it?

All things are quantum probability waves until an observer collapses them – so teaches physics. If there is no observer the universe is just all the possible states, all at once. So before there were people, who or what was observing the universe for it to have a definite state? How can there be any definite history of the universe between the big bang and the appearance of observers? Any definite history sufficient for instance to have definite solid planets, functioning stars and emerging evolving biology so as to give rise to the observers.

Physics requires a priori, an observer, to be anything other than an infinite mush of all possibilities.

So what constitutes an “observer” anyway? A plankton? A bacterium? A monkey? Whatever, no observer could have been around early enough to make the universe probability wave collapse into something that could give rise to that observer – it’s a paradox.

The answer is, of course, God. Oh how predictable those Christians are eh?

Now while you digest that, ponder this:

If a load of heavy stuff in a tiny place makes a black hole from which nothing can escape, how come the expanding big bang, which was ALL the heavy stuff there ever will be and all in a teeny weeny tiny place (to start with) didn’t disappear up its own bottom?

The answer is of course it was expanding fast enough to escape its gravity as it expanded faster than light and there wasn’t yet any space to curve into a hole as it was space itself expanding as it went. It wasn’t going backwards in time despite the expansion going faster than light as the time-space was expanding with the light, so the light was not travelling through space and time, it was travelling with space-time.

All this required an observer to actually be rather than potentially be. The only possible candidate is, as previously noted, God.

Arrow of Time

Space is multi-dimensional, unlike the two-dimensional trees in the brand new district of Cambridge, UK known as Eddington.

Space is expanding because the universe is expanding.

It is expanding away from every point in itself equally like every point on the surface of an inflating balloon. It started at zero size and now it is about 30 billion light years across.

You are such a point. You are on that surface of the space balloon. It is where you are and moving makes no difference as wherever you go it is the same for you. You cannot be on a different place relative to the whole universe because you are in the universe.

Everything is getting further away from you in space.

Now what about time?

It is just another dimension. It is expanding. It started at no seconds and now it is about 15 billion years in duration.

Just as you are at the expanding edge of the universe on space (the point on the balloon that you cannot get off) so you are at the expanding edge of time. Look anywhere and you look back in time. The further away that star is, the longer it took for its light to reach you.

You can only look backwards in space and time. You must travel forwards as the edge of space time expands with you stuck on it. You cannot see the forwards (future) space time as it has not yet been created, you are stuck in the here and now, only able to look back and see and remember the past.

That is the arrow of time. Simple. Easy. A child of five with a toy balloon could get it. Nothing to see here, move along. Little joke there of course. God bless.
