If a human being found the particles that made them up immediately converted into dark matter particles, how would things be different? Image credit: Max Pixel / Public domain.The differences between what you are and what you could be are stunning.The human body consists of somewhere around 1028particles, all bound together. The typical human has a mass of somewhere between 50 and 100 kilograms, and is largely confined to the surface of the Earth. Yet dark matter behaves very differently. It doesn’t interact with the nuclear or electromagnetic forces. It doesn’t collide with other particles or with itself. It only experiences a gravitational force, and as far as we can tell, that’s the only force it exerts. So what would happen to you, a human being, if instantaneously, all the particles in your body were converted into dark matter particles?Here on Earth, we’re made out of normal matter: mostly in the form of atoms. On a subatomic level, our atomic nuclei are bound together by the strong nuclear force, allowing a large variety of elements from the periodic table to stably coexist in the same body. It’s the electromagnetic force that holds our bodies together, binding these atoms into molecules, ...
