    When the engine moves a visible distance then I will start paying attention

    Before you get carried away with some company claiming revolutionary new technology
    remember Theranos


    A bit more depth

    Cool, but with these news I wonder what is the chance to find a perfectly aligned towards our point of view a black hole, a star system, etc, so that we see a perfect circle with no perspective.

    Creating a tiny amount of reactionless thrust. Which is way, way more unbelievable than warping space-time. I mean, space-time is warped all the time in nature, and warping it doesn't break any physics. But reactionless thrust has never been shown anywhere, and any amount of reactionless thrust either allows you to build a perpetual motion machine, breaking basically all of modern physics, or identifies a favored reference frame, breaking all of modern physics.

    Not that I believe in the space warpers either, but at least their claims are somewhat compatible with everything we know about the universe. Sadly, I think it's very likely that we will have to reach the stars the hard way.

    I dont believe the em drive is reactionless thrust

    Well within 3d
    All the stories about the EM drive and test descriptions indicate it is being evaluated on whether it is producing reactionless thrust. The debunkings thus far are the result of tracing thrust to measurement error or situations where there is an unaccounted for source of reaction, like outgassing of heated material or interaction of the powered wiring with the Earth's magnetic field.

    Thats the problem when your positive result falls below your margin of error

    Well, of course my approach to this stuff is sceptic, but we know that the cloth of space/time is not something as fixed as we thought. There may be distortions and other natural events that can... modify? it and there are so many things that science has yet to discover. So I just hope that within all this nonsense and crazy-sounding stuff, someday we may discover something which we can actually understand, prove and use.

    I like to think there is some kind of trick that someone will eventually discover can be pulled on space-time/magnetic fields/conservation of energy like how you can untie some knots by tricking the rope into thinking its just separate bits on one side.
    (tried to find a video eg but google-fu fail :no:)

    Then it's a null result, not a positive result.

    This entire perspective completely ignores the fact that the people who are most knoweldgeable about what we do and don't know about these things typically tell us they're impossible.

    Space-time doesn't warp randomly. Space-time geometry is determined by matter and energy. And the precise ways in which matter/energy warp space-time have been measured to an extreme degree of accuracy in a variety of circumstances.

    To break away from this and actually produce space-time geometry that would be really useful for a warp drive, you'd need to get your hands on matter/energy that has properties unlike anything that has ever been measured or even had any theoretical reason to believe it could possibly exist.

    Very interesting... Could you visit their page and read their paper and share your opinion with us?

    His point was most experts in the field dont thinks its doable
