Imagine that we have several $``$parallel$\text{'}\text{'}$ universes. In these various universes, space is nearly empty, save for a few elementary particles. Answer these questions regarding the various universes. Universe A: This Universe consists entirely of two protons that are separated by a distance of exactly $1$ meter. Compare the strength of the gravitational force between these two protons and the electromagnetic force between these two protons. Actual numbers are not needed$---$it is sufficient to have responses like $"...$ greater than $...\text{'}\text{'},"...$ the same as $...\text{'}\text{'},"...$ weaker than $...\text{'}\text{'},"...$ not enough information is provided $...\text{'}\text{'},$ etc. Universe B: This Universe consists entirely of one electron and one proton that are separated by a distance of exactly $1$ meter. Compare the strength of the gravitational force between these two particles and the electromagnetic force between these two particles. Actual numbers are not needed$---$it is sufficient to have responses like $"...$ greater than $...\text{'}\text{'},"...$ the same as $...\text{'}\text{'},"...$ weaker than $...\text{'}\text{'},"...$ not enough information is provided $...\text{'}\text{'},$ etc. Universe C: This Universe consists entirely of two neutrons that are separated by a distance of exactly $1$ meter. Compare the strength of the gravitational force between these two neutrons and the electromagnetic force between these two neutrons. Actual numbers are not needed$---$it is sufficient to have responses like $"...$ greater than $...\text{'}\text{'},"...$ the same as $...\text{'}\text{'},"...$ weaker than $...\text{'}\text{'},"...$ not enough information is provided $...\text{'}\text{'},$ etc. Universe D: Compare the strength of the gravitational force between the two particles in Universe A and the gravitational force between the two particles from Universe B$.$ Actual numbers are not needed$---$it is sufficient to have responses like $"...$ greater than $...\text{'}\text{'},"...$ the same as $...\text{'}\text{'},"...$ weaker than $...\text{'}\text{'},"...$ not enough information is provided $...\text{'}\text{'},$ etc. Bonus Universe: This Universe consists entirely of two protons that are separated by a distance of exactly $1$ meter. Compare the strength of the strong nuclear force between these two protons and the electromagnetic force between these two protons. Actual numbers are not needed, it is sufficient to have responses like $"...$ greater than $...\text{'}\text{'},"...$ the same as $...\text{'}\text{'},"...$ weaker than $...\text{'}\text{'},"..$ not enough information is provided $...\text{'}\text{'},$ etc. Explain this answer. Up to $2$ points added will be added.
