The EMDrive is one of the most perplexing problems facing scientists today, so perplexing that many refuse to believe evidence from NASA itself.
It is an experimental spacecraft engine that produces a thrust when everything in science as we know it says it should not. Many scientists have proposed theories why it is doing this, from redefining the background energy of the universe to why mass takes force to accelerate. But there is still controversy about whether it works. Until it is operated in Earth orbit and not in a lab, skeptics will continue to claim that the lab testing equipment is what is causing it to work. We are asking you to help us change that.
