That violates physics and is impossible, so you shouldn't be hopeful for that.
Instead you should be looking for new improvements on efficiency (exhaust velocity), cost, and thrust-to-weight-ratio. Continued marginal improvements on those things (and there's a lot to improve upon) causes massive changes in the future.
- grishka 6y agoThat violates physics as we know it, but there might be effects we don't know about just yet. Marginal improvements are boring. And besides, having to carry propellant is a significant limitation to the travel distance and one of the biggest nuisances of spaceflight. If you only needed electricity or other form of energy, but not matter, it would be much, much easier.
