How did the universe begin? theory involves quantum gravity

"For the past century, the greatest feud in science has been between Albert Einstein and himself," reports the New York Times:

On one side is Albert Einstein who in 1915 conceived the theory of relativity, which describes gravity as the distortion of spacetime by matter and energy. This theory predicted that spacetime could bend, expand, tear, quiver like a bowl of jello, and disappear into bottomless holes of nothingness known as black holes.


On the other side is Albert Einstein again, Rosen and another physicist, Boris Podolsky, who in a paper, pointed out according to the uncertainty principle of quantum physics that laid the foundations for quantum mechanics, the non-intuitive rules that inject randomness in the world – rules that Einstein never accepted. According to quantum mechanics, a subatomic particle like an electron can be anywhere and everywhere at once, and a cat can be both alive and dead until it is observed. A pair of particles would once be bound eternally, even if they were light years apart. Measuring one property of a particle – its direction of spin, for example – would momentarily affect the measurement of its companion. God does not play dice, Einstein often said.

Gravity rules space, shaping galaxies and indeed the entire universe, while quantum mechanics rules inner space, the arena of atoms and elementary particles. The two kingdoms have long seemed to have nothing to do with each other. This has made scientists unable to understand what happens in an extreme state like a black hole or to explain the beginning of the universe.

After much research over the past decade into the inner life of black holes has revealed unexpected connections between the two sides of the universe. The implications are staggering, including the possibility that our three-dimensional universe – and ourselves – might be holograms, like the barely discernible anti-counterfeiting images that appear on some credit cards and driver's licenses. In this version of the universe, there is no difference between here and there, cause and effect, inside and outside, or perhaps even then and now.

“It may be too much to say that gravity and quantum mechanics are exactly the same thing,” Leonard Susskind of Stanford University wrote in a 2017 study. “But those of us looking for it may already feel that the two are inseparable. and that neither has meaning without the other".

This idea makes Dr. Susskind and his colleagues hope that it could lead to a theory that combines gravity and quantum mechanics, quantum gravity – and perhaps that explains how the universe began. The Best Technology Site in Greecefgns
