I wish to know whether gravity has any effect on atoms? And if so to what extent ?
In summary, the conversation discusses the effects of gravity on atoms and whether or not it has quantum properties. It is mentioned that gravity affects atoms due to their mass, but it is usually negligible. The concept of quantum gravity is also brought up and a scientific paper is referenced. It is concluded that gravity does have quantum properties and it is suggested to read the references in the paper for more information.

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.

FAQ: Gravity Effects on Atoms: Extent & Impact
1. How does gravity affect atoms?
Gravity is a fundamental force that affects all objects, including atoms. It is responsible for the attraction between two objects with mass. In the case of atoms, gravity affects the movement and arrangement of subatomic particles, such as protons, neutrons, and electrons.
2. What is the extent of gravity's impact on atoms?
The extent of gravity's impact on atoms depends on the mass and distance between the atoms. The larger the mass and the closer the distance, the stronger the gravitational force between the atoms. However, the impact of gravity on atoms is relatively small compared to other forces, such as electromagnetic forces.
3. How does gravity affect the behavior of individual atoms?
Gravity affects the behavior of individual atoms by influencing the positions and movements of their subatomic particles. It can also affect the energy levels of electrons, leading to changes in the atom's chemical and physical properties. However, the impact of gravity on individual atoms is often overshadowed by other forces.
4. Can gravity cause changes in the atomic structure?
Yes, gravity can potentially cause changes in the atomic structure. In extreme cases, such as in the presence of massive objects like black holes, the gravitational force can be strong enough to break apart atoms and alter their structure. However, in everyday situations, gravity's impact on atomic structure is minimal.
5. How does gravity affect the behavior of atoms in different environments?
The effect of gravity on atoms can vary in different environments. For example, in a low-gravity environment, such as in outer space, atoms may behave differently than on Earth due to the weaker gravitational force. Additionally, the presence of other forces, such as electromagnetic forces, can also influence how gravity affects atoms in different environments.
