To understand gravity you don't need to build super-expensive devices to find the particle-interpretation of this wave force. The Higgs makes no sense outside the standard model. Studying the wave-interpretation as attracting force is easier and also alignable with general relativity.
Explaining an wide-reaching attractive force as particle really makes no sense at all (outside QM), as Heisenberg also complained.
For antigravity just look up M.Taijmar's work on the Thirring-Lense effect: https://patents.google.com/patent/WO2007082324A1/en?inventor...
