If I could explain it to the average person, I wouldn't have been worth the Nobel Prize.
Do not keep saying to yourself... "But how can it be like that?" because you will get ... into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
The commonly described history of the universe begins with conventional causal expansion. This means, for example, that thermodynamic energy had enough time to create rather uniform temperatures...to 'communicate' causal effects. Then from about 10-35 second to about 10-32 seconds an arbitrary scalar field is introduced [sometimes referred to a 'Higgs field']. 'Some models require more than one inflationary phase, in which case there would have to be a different scalar field for each'.
...'During the inflation stage we have a region of a false vacuum which represents a quantum mechanical phase transition to a vacuum different from the one we are familiar with today'...Lambda [the cosmological constant of expansion] was about 10 110 times it's current density.
A universe without matter is a hypothetical concept in which there is no physical matter or particles, and therefore no visible objects or structures. It is often used in thought experiments and theoretical models to explore the nature of space and time.
There are several different theories and models in physics that suggest the existence of a universe without matter is possible. These include concepts such as dark matter and energy, as well as the idea of a multiverse with different physical laws.
It is currently unknown whether a universe without matter would still have gravity. Some theories suggest that gravity is a fundamental force that exists independently of matter, while others propose that gravity is a consequence of the interactions between particles.
Without matter, it is unlikely that life as we know it would be possible. Physical matter is essential for the formation of stars, planets, and living organisms. However, some scientists have proposed the concept of "information-based" life forms that could exist in a universe without matter.
Currently, there is no way to observe or detect a universe without matter. Our understanding of the universe is based on the observation of physical matter and energy, so a universe without these components would be beyond our current technological capabilities.
