I’m a non-math person, but that doesn’t deter me from being logical and rational who churns out ideas, some of which are stupid, as you don’t have to be stupid to be stupid, I mean you could be as intelligent as Stephen Hawking and still be stupid.

Mr. Hawking acknowledges in his book the grand design that our universe is so finely tuned that it is impossible to have been created accidently but it seems he doesn’t want to believe his own conclusion so he came up with alternate solution.

To eliminate this finely tuned universe conclusion, which imply it has a purpose, he takes help of

M-theory, which predicts about 10^500 universes existing along with ours.by using M-theory

Mr. Hawking has reduced finely tuned universe impossibility to a probability of about 1 in 10^500.

Any gambler out there who want to bet on this odd?

The problem is M-theory has no scientific evidence to support it, and so to give it legitimacy Mr. Hawking

Uses Feynman multiple histories which states that a particle traveling from point A to point B takes all the possible paths and hence has infinite number of histories.

Since creation of our universe was a quantum event it has multiple histories about 10^500 and we happen to in one whose laws allow us to exist, this is what Mr. Hawking says.

How scientific, logical and rational is this?

Suppose we as observer who is outside the universe and have a button, when we press this button

Our universe freezes i.e. it stops expanding.

Now we fire a particle and when it reaches point B we press our pause button. According to Feynman our particle has taken all the available paths. Now the smallest meaningful length is a Planck-length

Let’s assume that each path that our particle has taken is one Planck-length in width and the next path will be another path one Planck-length wide. We count all the paths and assign it letter Z.

Now Z is the total number of paths that our particle has taken.

In his book Mr. Hawking says that we must take top down approach i.e. from present time we must go back in time towards the creation of our universe. We will do the same we go back in time and conduct our experiment again and pause our universe and count the number of paths our particle has taken and assign it letter Y.

We will find that Y is smaller than Z because as we go back in time our universe is becoming smaller and smaller.as we continue to go back in time we reach a point where our universe is only one Planck-length in size.

Now if we conduct our experiment we find that there is only ONE path that our particle can take and therefore our universe has single history, if we use the same logic as Mr. hawking’s

At this point Feynman multiple histories break down and so does Mr. Hawking’s idea that our universe has multiple histories.

does it?

In his book Mr. Hawking says:

“In the early universe—when the universe was small enough to be governed by both general relativity and quantum theory—there were effectively four dimensions of space and none of time.”

Now as we know that general relativity breaks down at quantum level, right?

And creation of our universe is a quantum event as told to us by Mr. hawking.

This means that our universe was in a state previous to the state that Mr. hawking described as small enough with four dimension of space and none of time, this means our universe existed in whatever form previous to the state when it was big enough to be governed by both general relativity and quantum theory but no time.

This in turn means there was a history or past to our universe when it was big enough with four dimension of space and none of time.

But please can someone explain to me how can we have history or past without time?
