Gravity is by far the weakest. In fact, it's about 10^39 times weaker than thestrong nuclear force, which holds atoms together.So, why is that? Well, there are a few theories that attempt to explain this. One of them is calledthe "graviton theory," which posits that gravity is caused by the exchange of particles calledgravitons. These particles are thought to be extremely light and have very little energy, whichwould explain why gravity is so weak.Another theory is the "brane theory," which suggests that our universe is a "brane," or athree-dimensional membrane, floating in a higher-dimensional space. According to this theory,gravity arises from the curvature of the brane, and the weakness of gravity is due to the fact thatthe brane has very little curvature.--- Support this podcast: https://anchor.fm/arsen-karapetyan/support
