Eli5. Why is gravity classified as a weak force when it can bend and trap light?
In: Physics
Gravity is considered weak because it is much weaker than the other fundamental forces. Sure, gravity can distort spacetime, but that requires a huge amount of mass. Compare it to the electromagnetic force. A magnet the size of your fingernail can easily hold up a paperclip, keeping it from falling to the ground. Gravity is so weak that the gravitational force of the entire Earth is weaker than the electromagnetic force of the magnet.
