Then there is also the possibility of the "big rip" as the expansion of space-time accelerates, long after all the stars are dead, the stretching of space-time may rip apart the galaxies (now mostly full of black holes, neutron stars, maybe a few ultra-long-lived 3rd or 4th generation red dwarf stars). Then eventually un-bind any planetary and multiple star systems, disintegrate planets and stars (or their remnants). And the ever accelerating expansion of space-time might overcome the strong nuclear force and disassemble atoms and particles.

HATE when that happens!
"anti-gravity" becomes semantically null when you define it that way.
If a magical, science-fictional style anti-gravity device was actually in view, yes. At the annual Anti-Gravity Research Conference, yes. In a silly forum conversation, no. Then you get people claiming that airplanes don't "resist the pull of gravity," as if that wasn't an airplane's job description.
As we know, terms can be defined be too loosely or too narrowly.
