Space contains trace amounts of matter throughout the universe. It’s primarily very hot (hundreds of thousands of degrees), coronal-like gas in most locations between galaxies. Once created, coronal gas lacks effective cooling mechanisms and is incredibly transparent, making the universe appear cold (3 Kelvin), the cosmic microwave radiation from the cooling down after the Big Bang. In addition to ordinary matter, there are neutrinos and other exotic particles zipping through ever volume of space along with radiation. Moreover, there is ten times more dark matter than ordinary matter in each volume and more dark energy than dark matter by three fold on average.
Space itself has structure, a sea teaming with quantum mechanical interactions and fluctuations. Both space and time were created in the Big Bang. There was no time prior to the BB and no way to be “outside” of the BB watching creation of the universe unfold.
This is a fascinating discussion, with a profound and astute truth being presented by a qualified physicist, and that truth being denied by those who cling to a shallow world view where space, time, and matter are taken to be primary and are not to be questioned. The irony is that the shallow world view is thought to be scientific by its adherents, and they dismiss the statements of the scientist as being unscientific.
I see space, time and things as being modes of thought. In ultimate reality beyond our senses those concepts have little or no meaning. Read “Reality is not What it Seems” by physicist Carlo Rovelli. One of his chapters is entitled “Time does not exist”.
IMO the practice of dogmatic scientism is based on ignorance and bigotry far worse than any religion.
Hey Chuck, You're never going to win a religious argument with reason. Time is infinite because "something" had to have existed before the big bang and they accept this as a matter of faith The only evidence they are willing to accept is that you prove that "nothing" exists and they are blind to the logical paradox of their own position.
"Space contains trace amounts of matter throughout the universe." - This is true.
"In addition to ordinary matter, there are neutrinos and other exotic particles zipping through ever volume of space along with radiation." - This too is true.
"Space itself has structure, a sea teaming with quantum mechanical interactions and fluctuations." - Part of this - the latter part is true - but the former part about linking space with structure is not true.
In other words, all of this matter, neutrinos, exotic particles, radiation, and quantum interactions, etc. exists IN space and independently of space. That in and of itself does NOT give space any actual structure or independent composition. If space has structure then it in and of itself must be composed of something, and what that something is The Astro Chuck hasn't identified. Why? Because he can't because space has no actual structure or composition. Things with structure just reside and move around within the concept we call "space".
That phrase is used to keep people aware that there is no center of the universe and that popular artistic depictions of the Big Bang (you know, the little bright light emanating things) are not correct. Like they explained before, if the universe is infinite or it's curved so that is finite but there are no boundaries (think of the balloon analogy), then all points started separating from each other, thus "it happened everywhere at once".
Humm, so "IT" Banged and all at once where there was no space anywhere, space appeared "everywhere" all at once Sounds like some illogical science to me.
I remember being impressed by a lecture by Lawrence Krause about the universe never being "empty". Even space with particles passing through it removed has quantum level virtual particles popping in and out. Not just interesting as a scientific point, but on religion, the false claim that there had to be God because nothing can come from nothing. Wrong. There's never nothing, it seems in science. Even in general language the word nothing is used generally but inaccurately. Nothing on my mind; nothing on my plate; nothing out there..etc Of course my mind is not empty, my plate has food crumbs on it, and things are out there.
