The world of the up-to-date Bousso theorem is still leaving our universe. For mathematical convenience, he assumed that there is an unlimited variety of particles – an unrealistic assumption that makes some physicists wonder if this third layer suits reality (with 17 or known molecules) better than the second layer. “We don’t have an infinite number of quantum fields,” he said Edgar ShaghoulicPhysicist from the University of California, Santa Cruz.
Despite this, for some experts, the work of Bousso provides a satisfactory consideration of the history of Penrose and Wall’s peculiarities, despite its unrealistic abundance of particles. He states that peculiarities cannot be avoided, even in space with bland reactions to quantum matter. “Just by adding small quantum corrections, you can’t prevent peculiarities,” said Penington. Wall and bousso’s work “answers are quite definite.”
True peculiarity
But Bousso theorem still does not guarantee that peculiarities must form in our universe.
Some physicists hope that the blind alleys will somehow disappear. What seems to be a personality can actually connect to somewhere else. In the case of a black hole, maybe these lithe rays are in another universe.
And the lack of peculiarity of the great explosion may mean that our universe has begun with a “great reflection.” The point is that the previous universe, which fell under the attraction of gravity, somehow avoided creating peculiarities and instead reflected in the period of expansion. Physicists who develop reflecting theories often work in the second layer of onions, using semi -class physics that uses Quantum effects of negative energy To bypass the peculiarity required by Penrose and Hawking. In the lithe of newer claims, they will now have to swallow the uncomfortable truth that their theories also violate the generalized second law.
One physicist chases reflections, Surjeet Rajndran with Johns Hopkins University, he says he is undetermined. He indicates that even the generalized second law is not true of the Gospel. Rejection of it would allow peculiarities that could be avoided and continuing the time of space.
Personality skeptics can also refer to the theory of onions, in which cosmic time behaves in a truly quantum way, for example, taking superposition. There, nothing can be considered something obvious. For example, it is complex to define the concept of the area, so it is not clear what form the second law should take, and therefore the up-to-date claims will not remain.
Bousso and similarly thinking physicists suspect, however, that the highly quantum arena without the concept of an area is tantamount to the blind part of the lithe ray, and therefore something that Penrose would recognize as a peculiarity should remain in the basic theory and in our universe. The beginning of space and hearts of black holes would really mean the edges of the map in which the clocks cannot touch and space.
“Inside the black holes, I am positive that there is a certain idea of peculiarities,” he said Netta EngelhardtA physicist in the myth who worked with Wall.
In this case, the basic theory of quantum gravity would not kill peculiarities, but it will demistify them. This real theory would allow physicists to ask questions and calculate significant answers, but the language of these questions and answers would change dramatically. Quantities in space, such as position, curvature and duration, can be useless to describe peculiarities. Where the time ends, other quantities or concepts can take their place. “If you had to guess me,” Penington said, “any quantum state describes the singularity itself, has no idea.”
