How is gravity related to electromagnetism I know that the equation for gravity and coulomb's law are basically the same but how can they be related when the strength of the forces are so dramatically different? :confused:

Electromagnetism and gravity have not been linked together. Their formula are similar because they are both inverse square relationships, not because of any physical similarity.

Do you think that there would ever be a possibility that they would ever be linked together?:D

[Capuchin]

The hope is to link all of the fundamental forces into a single theory, but that's a long way off yet, if it's even possible :)

The electromagnetic and weak force have already been linked in electroweak theory.

Gravity looks like it will be the hardest one to incorporate.

Does the strong force have the inverse square relationship?:)

[Capuchin]

Nope, it goes as so it dies off VERY fast as you move further away. It is only really felt between nucleons.

:) :) While gravity and electromagnetism is 1/R^2 and the strong force is 1/R^7 is that right cause if it is that was a huge help!!

[Capuchin]

I'm not totally sure that's right, but the strong force is negligible at few femtometers radius.

:) Newton's law of universal gravitation - Wikipedia, the free encyclopedia

it says Gm1m2/r^2 and coulomb's law is Kc q1q2/R^2 so if the strong force is 1/r^7 as it says on wikipedia then doesn't that mean if the particles get just a little bit away that the force gets much smaller. So even though at short distances it is strong because of 1/r^7 and the other forces are stronger at large distances because the force is not being divided by r^7 only r^2 is that right I think I'am confusing myself.

That's right, the strong force is incredibly strong at short range, but gets weak very quickly.
