Things behave in ways that can’t be explained by our current understanding of physics.
For example, galaxies rotate faster than we would expect. It’s as if there’s more matter in the galaxy than we could see. Scientists use the name ”dark matter” for this phenomenon.
Scientists don’t know if dark matter really exists, or if there’s other ways to explain this phenomenon. Another explanation is that there’s no extra matter, but that this is just how gravity behaves in large scales.
What’s interesting is that different galaxies has different amounts of ”dark matter”. Some have almost no ”dark matter” at all.
