positive mass surrounded by “negative mass” negating itself?

This seems like such a reach. Is negative mass another way of saying anti-matter?

I think these guys just throw stuff hoping it hits a wall. They don’t even care if it sticks anymore.

If absence of matter is basically a vacuum, that’s zero mass, but how would you get negative mass???
Also, if negative mass is so close to positive mass, why don’t they interact, combine, or clash? Even if it is mass without matter, which is hard to fathom, why are they stable together? And more importantly, even if it’s positive mass and negative mass (without matter), why wouldn’t they also negate each other’s effects on gravity?

‘Space’ is absence of ‘Matter’.

‘Matter’ is absence of ‘Space’......

If ‘Negative Mass’ exists, then there should be a corresponding ‘bump’ in the Space-Time Fabric instead of a ‘well’..............

I believe anti-matter has been shown experimentally to have positive mass.

And a pure vacuum is not “mass-free” due to zero-point energy. “Virtual” matter / antimatter pairs are continually springing into existence spontaneously and then self-annihilating in a seething background that is proven as well. Note the Casimir effect for example.

This phenomenon may witnessed in the Republican Congressional Conference.
