According to physicists, quantum particles are responsible for three forces of nature:
The fourth force of nature, gravity, is till now assumed to not originate from quantum particles, but from the curves in the space-time continuum, according to the celebrated physician Albert Einstein.

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...
The ‘curves in space’ theory of gravity is falling out of favour due to the fact that Einstein’s equations seem to work on our solar system but begin to break when we apply the same near a black hole or back in time, during the initial big bang.

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.

Scientists know four forces - things that attract or repel one object from another. The strong force and the weak force operate only inside the centres of atoms. The electromagnetic force rules objects with excess charge, and gravity
BHIP is a theory that discusses how when information in the form of particles goes past the event horizon, there is a possibility that the information is destroyed. This is problematic is because if this paradox is true, then everything we know about physics is wrong.
