Does Space Curvature Account for Gravity Between Individual Atoms?

In summary, the conversation discusses the two concepts of gravity - direct attraction between bodies and attribution to the curvature of space-time. The speaker also questions if the curvature of space-time can account for gravitational attraction between individual atoms. It is mentioned that on a micro scale, other forces are stronger and gravity is only relevant when it is spacetime curvature. However, it is uncertain how gravity works on a quantum level and if spacetime curvature will still be a useful model.

TL;DR Summary
Gravity/space curvature in relation to the accretion of dust in the Solar System et al
I am trying to come to terms with the two concepts of gravity, direct attraction between bodies (say dust even) and attribution to the curvature of space (time)
Looking at a physical sea coast I can envisage how every instance of the mass gravitational interactions of individual atoms or smaller can be incorporated into the ebb and flow of the tide, albeit on a scale that I can't even start to envisage from such an observation.

Having regard to the way in which the curvature of space-time is attributed to the 'gravity' between 'massive' solar objects is space curvature deemed to account also for gravitational attraction twixt even individual atoms or smaller?

Thanks
Martyn

On the micro scale there are generally other forces that are WAY stronger such that gravity is irrelevant but gravity IS spacetime curvature so ANY time gravity comes into play it is spacetime curvature.

Gravity is always spacetime curvature (not space curvature!) as it is currently modeled.

However, exactly how gravity works when the sources are small enough that quantum physics is important (such as an isolated atom) is not certain. General relativity can't do it and we don't yet have a working theory of quantum gravity. Depending on what that looks like, spacetime curvature may or may not turn out to be a useful model at that scale.

1. What is space curvature?

Space curvature refers to the bending or warping of space and time caused by the presence of massive objects. This concept is a fundamental part of Einstein's theory of general relativity.

2. How does space curvature account for gravity between individual atoms?

According to general relativity, objects with mass cause a curvature in space-time, and this curvature is what we experience as gravity. This means that even at the atomic level, the curvature of space-time caused by the atoms themselves is responsible for the force of gravity between them.

3. Is space curvature the only explanation for gravity between atoms?

No, there are other theories and explanations for gravity between atoms, such as the standard model of particle physics, which describes gravity as a fundamental force between particles. However, general relativity and the concept of space curvature provide a more comprehensive and accurate explanation of gravity at all scales.

4. Can space curvature account for the attraction between atoms and other particles?

Yes, space curvature can also account for the attraction between atoms and other particles, such as electrons. The curvature of space-time caused by the atoms creates a gravitational pull that attracts other particles towards them.

5. How does space curvature explain the behavior of objects in orbit?

Objects in orbit around a massive body, such as a planet around a star, are constantly falling towards the body due to the curvature of space-time caused by its mass. This creates a curved path of motion, which we perceive as an orbit. Without the curvature of space-time, objects in orbit would simply move in a straight line.
