Everything that is, always has been, and always will be.
I see the universe as being comprised of two perspectives. Existence, and meta-existence. Existence is what is; all macro, micro, atomic, and subatomic particle. Every force; nuclear, strong, weak, gravity, and magnetic. The void of space, and the fabric of space-time. While the other half, meta-existence is everything that can be, has been, and will be. It is a part of everything that is. If you think about yourself from the view of existence you can see the atoms that comprise you in every variation and position they have and ever will be in. You will see everything from the moment the universe was created, to the moment the last particle was rendered inert. However in the realm of meta-existence you don't just see every atom from it's beginning to its end. You see every atom, in every variation infinite in every direction. You see every possible creation, and destruction of those atoms. You see versions of them altered by different circumstances that may have occurred during their lifetime. You literally would see every possible outcome of every single atom infinitely stretched forever. This is because there is no end, and there is no beginning. Everything that is simply is. The persepctive of Meta-Existence is in essence the physics of allowance. This meta-existence attached to the particle allows it to be perceived in any point. It allows it to exist in any capacity.
When you look at cosmic expansion we can only account for a very small portion of the gravity necessary to drive the cosmos. We attribute the rest of the 94-96% of needed gravity to 'Dark Matter' and 'Dark Energy'. The problem is we cannot see, measure, or even detect Dark Matter/Energy. We only infer its existence because we see galaxies and other objects that move much too fast for the amount of observable gravity.
Our understanding of the universe is either wrong, or this form of energy must exist somewhere. Could it be that If the 4-6% of gravity in the universe consists of the actual matter of stars, and planets, etc which is quite a lot, that meta-existence somehow contributes to an actual weight attached to those particles? I don't think mathematically it would make sense that the gravity of a particle in all it's possible variations could be measured as Dark Matter, because if meta-existence is the infinite possible configuration of that particle, the gravity would be infinite and every particle would just rip-through space time. As well as if Dark Matter was attached to other particles directly their weight would simply just be increased. But maybe the nuclear forces, space-time, and existence itself somehow contribute to this equation. However whatever the case may be as of now we still scavenge the cosmos for clues about Dark Matter/Energy.
According to Friedmann and many other physicists at this point. The universe began from a singularity. An infinitely dense single point. When this singularity rapidly expanded outward it thrust all the energy and matter that would ever be into the Universe. Gravity began to pull at all the particles in the Universe. Larger bodies attracted smaller bodies as the actual curvature of space time was bent with the presence of matter. Gas particles compressed and stars were born lighting the Universe up. Primordial black holes may have been created under the pressure and heat of these early particles, and over time galaxies started to form while simultaneously all moving away from one another. Into the far outreaches of space.
It's postulated by Roger Penrose that when a singularity exists it is shielded from the sight of nature. This is known as the "cosmic censorship hypothesis" Stephen Hawkings posits that past the event horizon a singularity may be always in the future or always in the past. The reason for this is, in the case of the singularity that gave rise to our Universe for instance, as it was in a state of infinite density the ability to predict events was impossible and as space-time was infinitely curved time as of that moment was not an actual constant. However in the case of a black hole that is created by the collapse of matter (say a large star) when the weight of the matter compresses and a singularity is formed anything that enters past the event horizon instantly ceases to exist. Because time is not a constant, gravity is bent inward on itself infinitely and the laws of physics break down.
It's a rather interesting idea to think of an entire universe in infinite form yet without time, without physics. Though according to what we observe in the known Universe this had to be the case. That in some sense shows that time and physics do not need to be in place for something to exist. And without the pesky need to explain how something came to be from nothing we may just find the Universe didn't have to come from nothing in order to be created.
Time is a concept, a perceived event. It's not uniformly distributed. It's known that a particle traveling at the speed of light experiences time much differently than a static particle. As well as a particle stuck near the event horizon of a singularity. Time is distorted so that the experience of that particle in relation to itself is the same as any other circumstance, but outside of the range of distortion it seems to move slower, and slower until alas it stops altogether. Endlessly hanging at the border of the event horizon. Of course you can never observe this since not even light can escape the force, but it's an accepted theory all the same.
In the same way time is not necessary for something to exist. It's necessary for it to exist in multiple variations, and it's necessary for it to evolve and change form. But the rudimentary state of being is not dependent on time. Therefore it seems likely to me that creation, and destruction are Human concepts. Not truths of nature. Everything that is always is and simply changes form. Even the state of existence.
