Is There One All-Powerful SUPER FORCE Controlling The Universe? A new force of nature has been discovered: muons From attaching a magnet to a refrigerator door to throwing a ball into a basketball hoop, the forces of physics are at play in every moment of our lives. All the forces we experience every day can be reduced to just four categories: Gravity, electromagnetism, strong force and weak force. Now physicists claim to have found possible evidence for a fifth fundamental force of nature. The findings come from research conducted in a laboratory near Chicago. The four fundamental forces determine how all objects and particles in the universe interact with each other. Gravity, for example, causes objects to fall to the ground, and heavy objects behave as if they are stuck to the ground. The U.K.'s Science and Technology Facilities Council (STFC) said the result was "strong evidence for the existence of an undiscovered
