simplejack Posted March 23, 2009 Posted March 23, 2009 I've always wondered what the significance of gravity is to extremely small objects. What kind of gravitational force does a proton feel from a neutron or another proton? I thought that since very small distances between two protons' centers of gravity are so small that maybe gravity plays a pretty huge role in the nucleus. Even though the masses of two protons are so extremely small, their distances between one another are so extremely tiny, and since distance is inversely proportional to the force of gravitational attraction, gravity might just hold two protons together. Using this formula I disproved my theories, coming up with a tiny gravitational attraction. Has anyone ever dabbled in this sort of gravitational attration on a small scale that can give me some help in coming up with a different answer. I was hoping for an answer that would prove gravity to be stronger than the nuclear forces trying to pull protons apart.
Klaynos Posted March 23, 2009 Posted March 23, 2009 it is, as you've calculated, tiny, try the same for say the em force over the same range for two protons.
ajb Posted March 24, 2009 Posted March 24, 2009 As Klaynos has stated, the gravitational force between atomic particles is tiny. The electromagnetic and strong forces are much stronger and significant at these scales. However, classical gravity has only been tested to the mm scale!

There are proposals/attempts to use Casimir force experiments to test it at the micron level

As you said yourself - you had a hypothesis, and you demonstrated it to be incorrect. Welcome to Science™. Kaeroll
