The book delves into the quest for a theory of quantum gravity, focusing on Rovelli’s work in loop quantum gravity, which proposes that space is composed of finite loops woven into a network, challenging the notion of space as a continuous entity.

Any proposed theory of quantum gravity would need to take care of the principles of locality, which state that any variable can change independently while measuring the properties of any point in space-time. These variables are called the degrees of freedom.

The reason Einstein’s theory of general relativity works well in lower energy calculations and standard quantum techniques but not in higher energies and scales (like a black hole), could be because certain key features or ingredients of gravity are yet unknown to us, and are therefore missing fr...
Gravity is the only force in physics that affects matter on humongously large scales however it can't, on its own, explain certain astronomical observations.
There are two options that we could forego with: unseen dark matter - that provides for the missing gravity, or to ...
