      The puzzle I’m trying to solve right now is what dark matter is made up of. The matter we know about only makes up about 5% of the observable Universe, and we think that dark matter makes up another 30% (the rest being dark energy, which we know even less about!). I’m looking for a new type of particle that could explain this, but it’s not easy! There are loads of scientists looking for dark matter, so it could take a lot of time before we know the answer…
