I wish to know whether gravity has any effect on atoms? And if so to what extent ?
Gravity Effects on Atoms: Extent & Impact
Click For Summary
SUMMARY
Gravity has a measurable effect on atoms due to their mass, although this effect is typically negligible in everyday contexts. Atoms experience gravitational acceleration of approximately 9.8 meters per second squared at the Earth's surface. The gravitational interaction is influenced not only by mass but also by energy, as described by the stress-energy tensor in General Relativity (GR). Additionally, gravity exhibits quantum-like properties, a concept that is often misunderstood and requires further exploration of quantum gravity theories.
PREREQUISITES- Understanding of General Relativity (GR) and the stress-energy tensor
- Basic knowledge of atomic structure and mass
- Familiarity with gravitational acceleration concepts
- Awareness of quantum gravity theories and their implications
- Research the Einstein tensor equation and its implications in General Relativity
- Explore the concept of quantum gravity and its current theories
- Study the effects of gravity on atomic behavior in different environments
- Examine the paper by V.V. Nesvizhevsky et al. on gravity's quantum-like properties
Physicists, students of theoretical physics, and anyone interested in the intersection of gravity and quantum mechanics.

well atoms have mass so gravitation naturally affects them. but it's usually neglible.

Gravity acting on atoms is pretty much what most of our observable universe is all about.
The sum total of gravititational pull from each individual atom in the Earth acting upon each individual atom in the Moon is what keeps the Moon in orbit.

In a vacuum at the Earth's surface gravity accelerates each atom at the rate of about 9.8 meters per second^2 toward the surface.
If you find any atoms that have a different rate of fall please let me know!

the gravitational interaction is not only driven by particle's having mass. Energy is also a factor. In GR, spacetime is curved by the stress energy tensor, you know. Just look at the right hand side of the Einstein tensor-equation.inha said:
Besides, did you guys know that gravity DOES have quantum like properties [1]

Frome the little that is known about, "quantum gravity", i would say that is a bold statement, What are the facts ?

read the paper.besides, what exactly do you understand by quantum gravity. this is a term that is very often misinterpreted. we are not dealing with quantization, or whatever, of spacetime here

Oh thank the stars, a scientific paper with no strings attached.

it is a Nature paper manwolram said:
Besides, have you read the references in that paper, hmm ?
