  1. Speaking of Alpha Centauri, saw news on the EM-Drive again today:
    Science Alert – Leaked NASA Paper

    I think we’d heard rumors of this previously, but this appears to have more concrete details. Everyone seems to hype on ‘fuelless’, but you still have to get the energy from somewhere. It does make for a headscratching problem “What, precisely -is- happening here?” I happen to think it’s a multi-photon + atom collision weirdness that leads to an unexpected subatomic change, but who knows. This speculation would allow the ‘momentum’ to be something like emitted neutrinos that they simply aren’t set up to observe. The ‘lost mass’ would be very hard to observe directly. 😀
