Verified answer

Creation of the Universe

We make the assumption that there is a "hyper Spacetime" that has always existed.

Someone or something has always existed

God has always existed and created spacetime.

Spacetime has always existed

Both statements are equally valid. Take your choice.

Anyhow:

Spacetime is not nothing. It has properties, it can be bent, warped, twisted. Spacetime has structure. Spacetime is pervaded by Dark Energy. In fact, Dark Energy may be the structure of Spacetime, what we call the "Fabric of Spacetime

So, we have a huge amount of energy stored in the Fabric of Spacetime. A quantum fluctuation releases some of that energy as a Big Bang creating a universe. It is all a matter of scale This process has gone on in the past and continues today creating an infinite number of universes. We see the Big Bang not as a unique event, but as a regular event that fits with a logical, consistant physical process. Physics makes the most sense without unique events. A physics that allows unique events is unpredictable and borders on magic.

Random quantum vacuum fluctuations cause virtual particles to blink in and out of existence. A quantum fluctuation can also cause a universe to begin.

It used to be that science couldn't answer the question about the origin of the universe or of the Big Bang, but that didn't mean we should make up an answer (such as a god) and say that it was the cause. Within the last few decades scientists have discovered some good answers. Of course, a scientific explanation is more complex than simply saying, "God did it."

Quantum mechanics shows that "nothing," as a philosophical concept, does not exist. There is always a quantum field with random fluctuations.

There are many well-respected physicists, such as Stephen Hawking, Lawrence Krauss, Sean M. Carroll, Victor Stenger, Michio Kaku, Alan Guth, Alex Vilenkin, Robert A.J. Matthews, and Nobel laureate Frank Wilczek, who have created scientific models where the Big Bang and thus the entire universe could arise from nothing but a random quantum vacuum fluctuation in the quantum field -- via natural processes.

In relativity, gravity is negative energy, and matter and photons are positive energy. Because negative and positive energy seem to be equal in absolute total value, our observable universe appears balanced to the sum of zero. Our universe could thus have come into existence without violating conservation of mass and energy — with the matter of the universe condensing out of the positive energy as the universe cooled, and gravity created from the negative energy. When energy condenses into matter, equal parts of matter and antimatter are created — which annihilate each other to form energy. However there is a slight imbalance to the process, which results in matter dominating over antimatter.

I know that this doesn't make sense in our Newtonian experience, but it does in the realm of quantum mechanics and relativity. As Nobel laureate physicist Richard Feynman wrote, "The theory of quantum electrodynamics describes nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you can accept nature as she is — absurd."
