Question: Do you think that people will ever travel to different galaxies?

Craig Leff answered on 20 Jan 2020:

We’re concerned about how to get people to Mars and that would only take a few months. Getting to another galaxy would require so long that we would need a ship like an ark where people would live for generations, or warp drive like on Star Trek to get us there — while breaking the rules of known physics. I’d like to think we will do it some day, but it would be very difficult, to say the least.
