Recently, the people who measure neutrinos found a mistake in their experiment which probably shows that neutrinos don’t travel faster than light. They need to re-check it but most people think this mistake explains the measurement.
It was all to do with a wobbly cable…. We all make mistakes!
Neutrinos have very very little mass… so although they travel very quickly, they don’t actually have much energy. Imagine hitting someone really fast with a feather – you wouldn’t transfer much energy to them. Also they don’t interact with other matter in a normal way so collecting their energy would be really hard
