Concerning quantum gravity, it shows why a different approach is needed.
The fifth lesson 'Grains of space' introduces the idea of quantum gravity to explain the contradictions between relativity and quantum mechanics.
I also mention loop quantum gravity theory in reference to temporality.
Another theory for formulating quantum gravity is 'loop quantum gravity' (LQG).
If quantum gravity in a flat space allows for a holographic description by a standard quantum theory, then there must by physical quantities, which can be calculated in both theories -- and the results must agree," says Grumiller, who collaborated with colleagues from the University of Edinburgh, Harvard, IISER Pune, MIT and the University of Kyoto to carry out the research.
It's suspected that underlying both theories is a theory of quantum gravity, from which general relativity and conventional quantum theory emerge as excellent approximations just as Isaac Newton's theory of gravity, posed in the late 17th century, works fine except in some extreme situations.
In the present research, the mass of a black hole was computed on a computer based on Maldacena's theory, and the results were compared with the results obtained by approximate calculation based on conventional superstring theory, which incorporate the quantum gravity effects.
In fact, Hawking and Mlodinow are trying to develop "a law of initial conditions" through quantum gravity to address this problem.
The continual study of black holes may even lead the way to that holy grail of modern physics, a theory of quantum gravity.

London : Stephen Hawking, the British cosmologist who urged people to "be curious" in the Paralympics opening ceremony, has landed the richest prize in science for his work on quantum gravity and how black holes emit radiation.
To make it even harder, there is a lack of experimental evidence in the murky field of quantum gravity, and classical physics has really only observed the effects of gravity over larger ranges of 50 orders of magnitude of mass, i.
