EXCERPT: . . . Theoretical physicists developed a theory called loop quantum gravity in the 1990s that marries the laws of microscopic physics, or quantum mechanics, with gravity, which explains the dynamics of space and time. Javier Olmedo and Abhay Ashtekar and Parampreet Singh’s new equations describe black holes in loop quantum gravity and showed that black hole singularity does not exist.
“In Einstein’s theory, space-time is a fabric that can be divided as small as we want. This is essentially the cause of the singularity where the gravitational field becomes infinite. In loop quantum gravity, the fabric of space-time has a tile-like structure, which cannot be divided beyond the smallest tile. My colleagues and I have shown that this is the case inside black holes and therefore there is no singularity,” Singh said.
Instead of singularity, loop quantum gravity predicts a funnel to another branch of the space-time....
