In a step forward to unify the classical theory of gravitation and quantum mechanics researchers, through their calculations have obtained an uncertainty relation induced from the noise of gravitons—the hypothetical quantum of gravity.
- Quantum gravity is an attempt to reconcile two theories of physics — quantum mechanics, which tells us how physics works on very small scales — and gravity, which tells us how physics works on large scales.
- Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics.
- It deals with environments in which neither gravitational nor quantum effects can be ignored, such as in the vicinity of black holes or similar compact astrophysical objects, such as neutron stars.
- It has earlier been shown that when the gravitational field is treated quantum mechanically, it induces fluctuations, or noise, in the lengths of the arms of gravitational wave detectors like LIGO’s interferometer.
- Quantum gravity can help us understand the physics within black holes and the moments right after the birth of the universe.
- It can also aid us in understanding quantum entanglement, condensed matter physics and quantum information.
