“At the heart of quantum mechanics lie a few sacred rules for how to use the theory. First and foremost is. Roughly, that thou shalt not think about ordinary objects presently whizzing through ordinary space. Rather, quantum mechanics predicts — in exquisite detail — all the possible ways.” (Quanta, In Hilbert Space, All Things Are Quantumly Possible)
“That an object might turn out to be in the future. Exploring those possible futures requires tracking an entirely different mathematical object — an arrow known as a vector. One oriented in an expansive, alien domain.”(Quanta, In Hilbert Space, All Things Are Quantumly Possible)
“These arrows. They aren’t pointing at locations. “It’s a much more abstract space than that,” said Lucien Hardy(opens a new tab), a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada. They’re “really pointing in a direction in a possibility space.”(Quanta, In Hilbert Space, All Things Are Quantumly Possible)
This means that every quantum object has space. An electron or quark has its internal space. In the same way, the environment around those objects has space. Vectors don’t tell locations. They tell directions. Every quantum object travels into somewhere. That travel can happen in space and time. Or it can happen in space or time. So we should stop thinking of quantum objects as particles or items. Time can also be a quantum object.
In the same way, an energy level can be the object.
Quantum object. It can be more like information than a physical object. Information can be in two places.
At the same time. But the second thing is that. Information must reach the object.
If. Information cannot reach its target. That doesn’t change its shape.
The key feature of Hilbert space is that it has an arrow. That arrow describes an object's quantum state. David Hilbert introduced spacetime as an infinite set of geometric states. Each state. Of that model includes an infinite number of sub-states. This means that in Hilbert's universe, the particle or any object is not like a chair or stone in the regular universe. Those objects have three visible dimensions. But they have dimensions in time.
This makes Hilbert’s universe easy and, at the same time, hard to understand or model. This means. Every object exists and does not exist at the same time. Existence means observation. And if we cannot see something. That means we cannot know that thing. And if we don’t see an object. It doesn't exist. The object is handled as information. And information itself can exist in two places at the same time. Knowledge means existence.
Each quantum object. They might have multiple possible futures.
Before we see them. There. Is one. Interesting thing. The quantum object. It can be a single particle, object, or anything like that. The quantum vacuum. It can also be an object. We can think that the quantum object is an arrow. The arrow can involve multiple internal arrows. And that means that. If. We want to change the future of the quantum object. We can use a higher force in larger areas.
We can change the direction of the arrow. Quantum pressure. It must affect a large area. Or otherwise. We can say that the quantum pressure must turn the quantum object as a whole. If. That effective area is too small. It turns only a couple of arrows. And that destroys the entirety.
“We normally conceive of our Universe as having emerged from a preceding period of cosmic inflation, with our Big Bang occurring where one region of inflating space ceased inflating and transitioned to being dominated by matter and radiation. It's theoretically possible that instead we were birthed from the creation of a black hole in an earlier Universe, and that the black holes spawned in our Universe give rise to baby universes within them.” (BigThink, Do we live inside a baby universe that’s really a black hole on the outside?)
If we think about things. Like multiverse theory. That means. The Universe or space can involve multiple internal dimensions. And each of those dimensions can involve its own independent universe. This is the basis for an interesting model called the “Matrioshka universe”.
This model involves internal structures. Like. Internal spheres. The innermost object must have the highest or lowest energy level. The highest means that the energy level decreases from the innermost structure to the outermost. That pushes the entire universe's structures outwards. And that forms the shockwave around those internal spaces. That shockwave creates counter pressure. That keeps the system in its form.
(Quanta Magazine)
In opposite cases. There, the innermost structure is in the lowest energy level. That sucks the outer structures to it. And if the energy level decreases from out to in. That causes energy to travel in the middle of the structure. In that case, each sphere. Or. Box has a wave. Or some wall between them. When energy travels into the innermost sphere of that structure.
This model can work in black hole models.
It starts to glow. That glow keeps energy levels in those spheres in the right order. The outermost sphere sends energy. Into. The middle of the structure.
That means that there could be hollow singularities, black holes that can involve other dimensions and universes. There is a theory. That. The universe is a giant black hole. And we could live in a giant hollow singularity. The hollow singularity can form in fast-rotating plasma. Its energy level becomes very high.
When that plasma moves very close to the speed of light. And. High-energy X- and gamma rays can push those particles over the tipping point and turn them into black holes. Then those black holes can unite and form the hollow singularity. So this is one of the rarest theories about the shape of our universe and why we cannot see other universes. The hollow singularity stretches electromagnetic radiation into a straight form. Electromagnetic radiation requires waves.
So we can see those waves. If wave movement. Or superstrings that form the wave movement travel straight. Or. If the wavelength is very short, we cannot see that radiation.
It also pulls particles and electromagnetic radiation from inside it. This prevents us from seeing outside the universe. Energy from inside and outside the singularity impacts at that point. So the edge of the universe is at a higher energy level than space inside it. This means it forms the standing energy wave between the universe and the space outside it. But that is only one model of the universe.
Even if that hypothetical hollow singularity doesn’t exist. There. Is a plasma wave. That travels through spacetime. That wave left from the Big Bang. Because that wave is not dense.
It allows. Electrons and wave movement to travel through it. Wave movement and particles can travel through it. That causes whirling. And those whirls form entropy. That denies the observations from outside the plasma wall. That interaction makes the wave glow. That makes it impossible to see through that plasma wave. But those whirls also steal energy from that structure.
