Why should the four forces be equal in strength?

[Quantum321]

Physicists believe at one time there was only one force. As the BB cooled the four forces we know today are derived from that one force. Why must the four forces all be equal?

 

[FactChecker]

Why do you say they are equal? Gravitation is many orders of magnitude weaker than electromagnetism.

 

[Quantum321]

This is the problem. Physicists wonder why gravity is so much weaker than the other forces..this implies they think all the forces should be the same

They don't have to be equal, but it looks odd that three are comparable (and, on a dimensionless scale, close to 1), and the fourth one is a factor 10000000000000000000000000000000000000000 weaker than the others. It would be nice to find some reason for that.

Perhaps the OP is referring to why in a past epoch the four forces were assumed have been equal.

 

[Quantum321]

I think mfb is right. The question is why is gravity so weak regardless of the strength of the other forces.

Perhaps the OP is referring to why in a past epoch the four forces were assumed have been equal.

Isn't that because they were super-symmetrical in the early universe?

 

[mfb]

This has nothing to do with supersymmetry.

 

[Khashishi]

Because physicists want to unify the forces. Who knows if this is actually possible. If all the forces come together at some point, then they ought to approach the same strength as they approach that point.

Why is gravity considered a force? Gravity appears to be emergent and a consequence of space~time interaction. As mass and space interact what appears to be gravity is the action of mass slowing time in space... I think this is Einstein's theories interpretation.
