Quantum Gravity
A system can’t change while you are watching it.
Quantum physics tells us that even in empty space, virtual particles are constantly created and destroyed. The fleeting particles endow every cubic centimeter of space with a cubic centimeter of space with a certain that, according to general relativity, produces an anti-gravitational force that pushes space apart.
Quantum Gravity
Theorists have taken up more radical approaches to Quantum Gravity, the most popular approaches are String Theory and Loop Quantum Gravity (LOG). String theory try to unify gravity with the other fundamental forces, but LQG make no such attempt. Instead, they make an effort to quantize the gravitational field while it is kept separate from the other forces. Strictly speaking, the aim of Quantum Gravity is only to describe the Quantum behavior of the gravitational field and should not be confused with the objective of unifying all fundamental interactions into a single mathematical framework. A theory of Quantum Gravity that is also a grand unification of all known interactions is sometimes referred to as the theory of everything (TOE).
Quantum Zeno Effect (QZE)
QZE is a phenomenon in Quantum physics where observing a particle prevents it from decaying as it would in the absence of observation. This has been confirmed in an experiment by Cornell physicists. Their work will help us to control and manipulate the Quantum states of atoms.
Topos theoretic approach also deals with better understanding to quantum gravity
