I've been curious about this ever since I watched Bob Lazar's videos in the way way way back when. My question is, does anti-grav remove the weight of the ship/craft using it? Like does that mean can we manufacture crafts that carry millions of tons of cargo, and then just dial up the AG? I totally understand the generic concept, thru Bob, but the mechanics elude me. I read a 1000+ sci-fi space operas and they all have "their" version of how this plays out, w/o going into detail, of course.
I was just wondering if anyone could explain the "lift properties(?)." I think that's my question. I presume the amount of lift would be proportional to the device, but again this is just speculation and I have 0 science background...lol
I'm not expecting an answer, per se, but more of a conversation, to help me understand.
Thank you.

I was big into Bob Lazar back when I was a teenager. As I've gotten older, I've realized his claims don't mesh well with known physics. He claims that the field of the strong nuclear force has a range that goes past the perimeter of the element 115 atom, which allows it to be accessed and manipulated by technology. That doesn't make a whole lot of sense, given that the strong nuclear force normally has a range only on the same order of magnitude of the size of the nucleus itself. How can it be that the strong force suddenly balloons in range on the order of 100,000 times normal in the element 115 atom? The nucleus is very, very small.

Antigravity in general is, at this point, a hypothetical phenomenon. The equivalence principle seems to imply that the existence of a "true" antigravity device is impossible. Even if something like negative mass exists, the equivalence principle still implies that it would have a gravitational field that would attract ordinary matter, not repel it (paradoxically, negative mass is predicted to feel a repulsion from normal matter, resulting in one mass chasing the other seemingly without end).

The closest thing I can think of that might have the same desired effect as antigravity would be an Alcubierre warp drive. If you can use it to contract the space in front of you and expand it behind you in order to move forward, I don't see why you couldn't also use it to contract the space above you and expand it below you in order to move up and away from a source of gravity.
