QED works to the best ability of any test, down to one part in ten billion, so looking very close indeed. Then in order...
What is gravity? The geometry of spacetime.
What is a particle? A localized excitation of a field.
It may be that you don’t like or understand the answers, but they exist and allow people to make precise predictions, build machines that work based on said principles. Maybe you’re confusing scientific answers with philosophical ones?
Fundamental = bedrock
