To go even further, "particles" are also a construction of ours, a representation of an even more "diffuse" reality. "Spacetime is doomed. There is no such thing as spacetime fundamentally in the actual underlying description of the laws of physics.

So if there's no spacetime, it's not clear what physics is about." - Nima Arkani-Hamed Cornell Messenger Lecture 2010.
