What would it actually be like if every particle in your body converted into a dark matter particle? And how long could you last in that state? Everything that we can see in the Universe is a massive mash-up of electrons, protons and neutrons fused into atoms. It's what is called baryonic, or just ordinary, matter. Your body is made up of it too. But there is a lot of stuff out there that we don't see, stuff that we call dark matter and dark energy. https://invidio.us/watch?v=ms9eSJYr4o8

Physics is not about learning about objects. It is about learning, Where Do We Come From? What Are We? Where Are We Going? Physics is about learning about us and all creatures, as well as all the Universe which we are all an intimate part of. From the creatures to the planets and time itself.
