Question

Why is gravity considered a weak force?

Answer 1

Gravity is considered very weak force because it measures very small, for example, it is `10^40` weaker than the electromagnetic force that holds atoms together. Why is weak is still been researched, but there is a speculative hypothesis that says it is weak because of the multi-dimensional nature of the universe, hypothesized to be 10 by the String Theory. The 10 dimensions cause Gravity to leak thereby weakening it significantly. Interesting hypothesis, but I am skeptical about it.
