Could dark matter be powering the EMdrive?
If the impossible space engine works, could dark matter reconcile the laws of physics with these bizarre experimental results?
“…axions are potentially detectable through their weak coupling to electromagnetism…” -Aaron Chou
For every action, there’s an equal and opposite reaction. This formulation of Newton’s third law has two very important modern consequences: one, that there’s a physical quantity that’s always conserved in the Universe (momentum), and two, that the laws of physics are the same irrespective of your position in space. This has a huge slew of implications, including that if you want to power a device to change its motion, you need to push against something. This could be exhaust from a rocket, tires pushing against a road, train wheels on a rail-line or even photons reflected off a sail. The one thing that’s forbidden is a reactionless drive: an action without a reaction. That’s exactly what the EMdrive — the “impossible” space engine just verified by a NASA test — claims to be. If it truly works as advertised, it violates the laws of physics. But there’s a possible loophole: perhaps there is a reaction, and we just don’t detect it. Perhaps the reaction occurs, but it’s occurring due to dark matter.
