"HOW COULD THE UNIVERSE CREATE ITSELF FROM NOTHING?"
[This is the title of a recent article by James Marshall. Here follows his brief explanation]
The reason why it is so difficult for us to grasp this concept is due to a common misconception about the meaning of the word "nothing" in this context. We typically think of "nothing" the way we would perceive the inside of an empty shoe box. Open the lid and look inside, we see nothing. How could it be that something then magically appears out of nowhere inside that box?
When talking about the origins of the universe, "nothing" means a state where there is nothing of substance in existence, because there is neither positive nor negative energy - no heat, no cold, no atoms of anything.
However, in this particular nothingness, energy still exists (quantum energy). It does not have a physical form. It can exist in physical form, it just doesn't because all of the positive energy is perfectly counterbalanced by all of the negative energy.
Time has no meaning, because there are no atoms to move around and give meaning to time.
We don't have a word in common English to properly describe such a state because this situation only existed prior to the existence of the universe, so we use the next best description which is "nothing". (A better description might be "neutral state").
Various theories exist as to why this state rapidly changed about fourteen billion years ago to produce a universe - our universe. Some physicists suggest it was random quantum fluctuations.
Even at this point this might sound far fetched, but physicists claim to have detected and even created these fluctuations:
Physicists Say They've Manipulated 'Pure Nothingness' And Observed The Fallout
Perhaps these fluctuations have always existed, but it was only when these fluctuations randomly aligned that a strong enough force existed to create a minuscule imbalance between positive and negative energy.
This in turn started a cascade reaction that grew and grew, until eventually there was enough positive energy to take on a physical form and the early universe popped into existence – as a dense ball of energy that initially expanded, then eventually cooled sufficiently for a separate process to occur whereby that energy formed into individual atoms (about 10^80 of them).
We call that process "The Big Bang".
It is more than just a theory.
There is strong empirical evidence that it did occur, such as the movement of the galaxies and background cosmic radiation.
The atoms that were created during the Big Bang would eventually bind to create the simplest elements, hydrogen and helium, which condensed to form stars, which in turn created the denser atoms through processes such as the death of stars.
Eventually, all of the different types of atoms have combined in various marvellous ways to create everything in the universe, from the galaxies to you and I.
So as you can see, everything really did come from ‘nothing’.
Terence Meaden has written an inexpensive explanatory book, published 2018, about the origins of the Universe, Life and Humankind in 92 chapters and 312 pages----for which see Amazon. It is called "A New Bible in Three Testaments".
Terence, without a testable hypothesis and empirical evidence—more than theory or logic—it’s not science. Einstein himself failed.
In such matters it is entirely logical to construct hypotheses that take account of and embrace all known laws of physics and test them for good sense and syllogistic reasoning using the best arguments and mathematical tools available at any epoch. This is good science and mathematics. Who can say that more practical testing may not become available in the future?
Albert Einstein was ahead of his time in every way, and today's theorists working in string theory appear to be as well. We cannot tell what sorts of unexpected theoretical advances will be made in the future---and the future ahead is very very long indeed.
