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.

Gravity is considered a weak force compared to the other fundamental forces because its effects are much weaker at the atomic and subatomic levels. For example, the gravitational force between two electrons is approximately 10^40 times weaker than the electromagnetic force between them. Additionally, gravity has no repulsive component, unlike the electromagnetic and strong nuclear forces, which further contributes to its perception as weak in comparison.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
