Let us hear no more of this.
Of course, we will anyway. Just like cold fusion, a group of diehards will rant and rave about closed-minded scientific priesthood quashing their glorious rebellion no matter how many times they fail to build a working spaceship.

Some scientific pros built and tested an Em Drive.
On the one hand it showed thrust. On the other hand it showed the exact same thrust when the blasted engine was turned off
Turns out the Earth's magnetic field interferes with the measuring system, the Em Drive does not work.

The NASA tests struck me as being in far too small a chamber.
ReplyDeleteAhahaha hahahaha!!!!!!
ReplyDeleteI haven't come across anything that seems to strongly dispute the Mach Effect Thruster approach. Global Conservation of Energy and Momentum get preserved (local gets complicated though), so it's perhaps not entirely bonkers.
ReplyDeleteThe NASA experiment seems to be similar to the results of an experiment done by Oak Ridge scientists 20 years ago, where they also detected a thrust about 100 times stronger than predicted by Woodward. John Whealton argued this was due to time varying thermal expansions instead. It's possible that this is the same issue NASA ran into. If so, this effect needs to be accounted for and see if there is anything remaining. Thermal expansion sounds like a tough issue to eliminate though, and trying to measure a 1% difference in acceleration sounds as tough.
According to some, we've had the tech to take ET home for decades now. So, why all the fuss about technology that may or may not work? Is it just to distract the masses from the unaccounted trillions spent on black budget projects?
