We know pretty well what matter is and how it interacts with the others.
Dark matter interacts through gravity but not light. Beyond that I haven’t heard much else.
And lastly anti-matter has an opposite charge and interacts with matter through annihilation. I think I remember hearing that it would react with dark matter the same way.
So my question is, does anti-dark matter exist, and what are it’s properties?
The problem with dark matter is that we don’t know what it is. If it’s a particle, then presumably there probably would be an antiparticle for it. However, we don’t actually know if it’s a particle or not.
There’s some hypotheses that say that dark matter doesn’t physically exist, and that our theories of gravity are just incomplete. There’s some other hypotheses that say that dark matter might be really small black holes. And then there’s some hypotheses that say that dark matter is a particle. Until we find out more about what it is, we simply can’t say for sure what sorts of properties it has
Speaking of our incomplete theory of gravity, do gravitational waves behave similarly to ocean waves in that they can combine together to create a bigger wave? And if so could there be rogue gravitational waves like there are rogue waves in the ocean?
