>>11514313It's not ignored at all by physicists. The predominant theory of gravity (Special relativity) stands alongside the predominant theory of the other 3 fundamental forces (Quantum Field Theory/Quantum Mechanics)
Of the two; relativity and quantum mechanics, quantum mechanics is the one most people are more intimately aware of because of it's endless (mis)representation in pop-sci and other media. But that doesn't mean that we're ignoring the other. In fact some of the most highly competitive fields of modern physics are those that aim to further our understanding of gravity among other things (String theory and quantum gravity).
Also observational insight is harder to come by for gravity, compared to the other forces, the force carriers(Gauge Bosons) for all the other forces have been discovered at particle accelerators at almost regular intervals over the past several decades and their properties are constrained and well understood. A gravitational gauge boson may not even exist and most of our information comes from celestial sources (LIGO gravitational wave discovery, orbit of mercury, lensing etc), which carry a truckload of extra complications with them.
TLDR; No one's ignoring it, it's just that compared to the other forces interest is lower and experimental hurdles are higher imo. That being said I'm only a grad student not a post-doc or anything so don't take my thoughts too seriously
