For example, if the big bang had been one-part-in-a billion more powerful, it would have rushed out too fast for the galaxies to form and for life to begin.

Physics tells us observations can't be predicted absolutely. Rather, there's a range of possible observations each with a different probability.

We take for granted how our mind puts everything together.

I think the answer of course is that space and time are not these hard external objects. Again we're, scientists have been building from one side of nature (physics) without considering the other side (life in consciousness). Neither side exists without the other. They cannot be divorced from one another or else there is no reality.

When you turn from one room to the next, when your animal senses no longer perceive the sounds of the dishwasher, the ticking clock, the smell of a chicken roasting - the kitchen and all its seemingly discrete bits dissolve into nothingness - or into waves of probability.

Until we recognize the essential role of biology, our attempts to truly unify the universe will remain a train to nowhere.
