Does gravity affect quantum mechanics?

Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics, and where quantum effects cannot be ignored, such as in the vicinity of black holes or similar compact astrophysical objects, and where the effects of gravity are strong, such as …

What if gravitons exist?

In string theory, believed to be a consistent theory of quantum gravity, the graviton is a massless state of a fundamental string. If it exists, the graviton is expected to be massless because the gravitational force has a very long range, and appears to propagate at the speed of light.

What would happen if there was no gravity?

Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence.

Is quantum gravity a physical theory?

Quantum Gravity. First published Mon Dec 26, 2005; substantive revision Wed May 27, 2015. Quantum Gravity, broadly construed, is a physical theory (still ‘under construction’) incorporating both the principles of general relativity and quantum theory.

What is 0quantum gravity?

Quantum Gravity, broadly construed, is a physical theory (still ‘under construction’) incorporating both the principles of general relativity and quantum theory.

Does gravity exist in the universe?

GRAVITY DOES NOT EXIST….gravity is an illusion and does not exist in the Universe on a galactic scale. Gravity is an internal force, it is in the atom and molecule only and there is no external gravity force as we have been taught to believe. We can say that… “Gravity exists on the Quantum Mechanics level only”.

What if there is no theory of gravity?

“If there is no theory [of quantum gravity], then the universe is just chaos. It’s just random,” said Netta Engelhardt, a theoretical physicist at the Massachusetts Institute of Technology. “I can’t even say that it would be chaotic or random because those are actually legitimate physical processes.”
