Is anti gravity here? Or is it an April fool?

NASA Veteran’s Propellantless Propulsion Drive That Physics Says Shouldn’t Work Just Produced Enough Thrust to Overcome Earth’s Gravity

A veteran NASA scientist says his company has tested a propellantless propulsion drive technology that produced one Earth gravity of thrust.

It is either a massive hoax or ... a future Nobel prize in Physics.

There was an old Robert A Heinlein story about "torch" pilots who rode space ships that had constant acceleration and thus could reach significant speeds for long segments of their run. A constant 1.00001 g acceleration gets you off the Earth - slowly. But it gets you to the Moon really fast once you have escaped enough of Earth's gravity that your 1.00001 g is a LOT more gravity than you feel from the Earth below you. That 1 g if held constant even gets you to Mars in a reasonable flight time. You spend the entire flight either accelerating or decelerating but if you have a long-lived power source that can last for the entire round trip, you have what you need to explore the solar system. The interesting part there is that since you are in a constant 1 g acceleration, you don't suffer the problem of muscular atrophy that a long-term flight would cause.

The "Bart" Drive

Another attempt at creating an em Drive is named the BART drive because some of its components look like Bart Simpson's hair! https://www.popularmechanics.com/space/rockets/a33917439/emdrive-wont-die/
