It’ll take about seven months to send humans to Mars using today’s spaceships. That’s not exactly a quick jaunt, but it is doable.

Trips to other planets could take years, though, and if we want to explore the rest of our solar system — or the places beyond it — we’re going to need a faster way to travel.

Now, a physicist has designed a new rocket thruster that could potentially allow humans to travel 10 times faster in space — and it’s inspired by nuclear fusion.
