Hunting a basic theory of quantum gravity
The world of the new Bousse theorem is still far from remarkable ways from our world. For mathematical convenience, he assumed that there was unlimited particles – an unrealistic assumption that makes some physicists wondering whether this third layer corresponds to reality (with 17 or its known particles). “We do not have an unlimited number of quantum fields,” said Edgar Shagulian, a physicist at the University of California, Santa Cruz.
However, for some experts, Bosu’s work, despite the unrealistic abundance of particles, offers a satisfying story to the Penrose and Wall Singularity story. This proves that even in the space of space with a mild reaction to the quantum matter, the shakes cannot be prevented. “Just by adding a little quantum correction, you can’t prevent singularity,” said Pington. Wall and Bousse’s work “answer that is completely definitive.”
Real singularity
But the Bousse’s case still does not guarantee that the singles must be formed in our world.
Some physicists hope that the deadlock will somehow be destroyed. What seems to be a singularity can actually be attached elsewhere. In the case of black hole, those light beams may end in another world.
And the absence of a large explosion may indicate that our world began with “great bolitude”. The idea is that a former world, as it fell under the gravity, somehow deceived the formation of a singularity and was instead of a period of expansion. Physicists who are developing bumpy theories often work in the second layer of onions and use semi -classical physics that abuse negative energy quantum effects to sing the Penus and Hawking judiciary. Given the newer theorems, they must now swallow the uncomfortable truth, whose theories also violate the generalized law.
One physicist who is looking for jumps, Surjet Rajandaran of the University of Johns Hopkins, says he is wanted. He points out that even the second general law is not the truth of the Bible. Rejecting it allows the singles to be avoided and the space-time can be continued.
Technology pessimists can also use this theory in the onion kernel, where space-time treats quantum methods, such as cloud use. There, nothing can be awarded as. For example, it is difficult to define the concept of the region, so it is unclear what the second law should take, and so the new theorems do not maintain it.
However, kissing physicists think that a very quantum and without imagination of the region for a light beam is a deadlock, so what Penrose recognizes as a singularity must remain in our main theory and world. The beginning of the universe and the heart of the black holes really show the edges of the map that clocks cannot tick and the space stops.
“In the black holes, I am positive that there are some concepts of singularity,” said Netta Anglardet, a Wall physicist who worked with the Wall.
In this case, the essential theory still unknown about quantum gravity does not eliminate the singularities but changes them. This real theory allows physicists to ask and calculate meaningful answers, but the language of these questions and answers change dramatically. Space-time values such as position, curvature, and time may be useless to describe a useful singularity. There, where the time ends, the values or other concepts may take their place. “If you had to guess me,” whatever the quantum government describes has no concept of time, “Pington said. “
