Question: What's the greatest thing you think we'll be able to do using dark matter?

Very difficult to say until we know exactly what properties dark matter has! Because it doesn’t interact with the electromagnetic force, it will be very difficult to harness. I’ve seen some ideas that it could be used as propulsion for long-distance spaceships, but honestly this idea has more problems than benefits at the moment.
