Physicists think they've just discovered a fifth force of nature, and if so, it could totally redefine how we understand the workings of the universe. Physics can be a pretty daunting subject, especially for the layperson, but one of the field's most straightforward fundamentals is that everything in the universe is controlled by four fundamental forces of nature: gravity, electromagnetic force, and weak and strong nuclear forces. If physicists in Hungary are correct, this most "straightforward" of all aspects of physics may not be straightforward at all
As Science Alert explains, before you can grasp the fifth force of nature physicists believe they have discovered, you have to understand the first four. To put it lightly, the four forces of nature are pretty important when it comes to science's understanding of the workings of the universe. They are the foundation of the standard model of physics, which scientists use to explain all of the particles we observe in the universe as well as the behavior that governs them.
