Hippos sometimes attack humans too. “They don’t go out and hunt humans, but if you encounter them on the way back to the water and you are in between,” says Eksteen, “then you have to make a plan!” In Niger in 2014, 13 people drowned when hippos overturned their boat.

If there are strangelets flying around the universe, then occasionally a strangelet should hit Earth, where it would appear as an exotic type of cosmic ray. If strangelets can be produced in high-energy collisions, then they might be produced by heavy-ion colliders.

The more specific and hypothetical context is that quark matter might in fact be the true ground state of all matter, and thus more stable than ordinary nuclear matter. This idea is known as the “strange matter hypothesis”, or the Bodmer-Witten assumption.

In modern physics, antimatter is defined as matter that is composed of the antiparticles (or “partners”) of the corresponding particles of “ordinary” matter.

Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
