The world of the new Boussois theorem always deviates from our universe notably. For mathematical convenience, it assumed that there is an unlimited variety of particles – the analistic hypothesis which makes some physicists wonder where this third layer corresponds to reality (with its 17 known particles) better than the second layer. “We have no infinite number of quantum fields,” said Edgar ShaghoulianPhysicist at the University of California, Santa Cruz.
However, for some experts, Bousso’s work delivers in the ending of the history of the singularity of Penrose and Wall, despite its unrealistic abundance of particles. He establishes that singles cannot be avoided, even in spatial time with mild reactions to quantum matter. “Just by adding small quantum correspondents, you cannot prevent singularity,” said Penington. The work of Wall and Bousso “answers this subject quite definitively”.
The real singularity
But Bousso’s theorem still does not guarantee that singularities should forms in our universe.
Some physicists hope that the dead ends disappear in a way. What looks like a singularity connects elsewhere. In the case of a black hole, perhaps these light rays are found in another universe.
And the lack of singularity of the big bang could imply that our universe began with a “big bounce”. The idea is that a previous universe, while it collaborated under the attraction of gravity, somehow dodged the formation of a singularity and rather rebounded in a period of expansion. Physicists who develop rebounded theories often work in the second layer of the onion, using semi-classical physics that exploits Quantum effects of negative energy To bypass the singularity required by Penrose and Hawking theorems. In the light of new theorems, they will now have to change the uncomfortable truth that their theories also violate the second general law.
A physicist continuing the rebound, Surjeet Rajenndran From Johns Hopkins University, says it is flawless. He underlines that no second general law is the evangelical truth. Rejecting it would make it possible for the singularities and continues of space-time possible.
The skeptics of singularity can also appeal to theory at the heart of the onion, where space-time behaves in a truly quantum way, such as the taking of overlays. There, nothing can be taken for granted. It is difficult to define the concept of zone, for example, it is therefore not clear what the second law shows, and therefore the new theorems do not hold.
Bousso and physicists with similar views, however, suspect that a very quantum arena without a notion of zone is equivalent to a dead end for light rays, and therefore that something that Penrose wound recognizes as a singularity should persist in central theory and in our universe. The beginning of the cosmos and the heart of the black holes would really mark the edges of the map where the clocks cannot check and the space stops.
“Inside the black holes, the AM positive, there is a notion of singularity,” said Net EngelhardtPhysicist at MIT Whho has the world with Wall.
In this case, the fundamental theory still unknown of quantum gravity would not kill singularities but would demystify them. This truer theory would attract physicists to ask questions and calculate significant answers, but the language of these questions and answers that is injured in series. Quantities in space-time such as position, curve and duration can be useless to describe a singularity. Where time ends, other quantities or concepts may have to take their place. “If you have to make me guess,” said Penington, “whatever the quantum state, the singularity itself does not have a notion of time.”
