Not on but of,er by how the particle relates to the background. It either sits . the background, or it is an excitation . the background. We argue that by choosing the former to construct our fundamental theories we have made a costly mistake. Instead we should think of particles as excitations of a background. W

Is Quantum Linear Superposition an Exact Principle of Nature?,or molecules having masses up?to ten thousand amu, and also in collective states such as SQUIDs and Bose-Einstein condensates. However, the principle does not seem to hold for positions of large objects! Why for instance, a table is never found to be in two places at the same time? One possible expl

Quantum-Informational Principles for Physics, as the relativity and the gravity-acceleration equivalence. The validity at the Planck scale of such principles is under dispute. A constructive criticism engages us in seeking new general principles, which reduce to the old ones only in the already explored domain of energies. At the very basis of

The Universe Is Not a Computer, reality, plug it into some dynamical equations, and then map the time-evolved result back to real-world predictions. But while this computational process can tell us what we want to know, we have taken this procedure too literally, implicitly assuming that the universe must compute itself in the sa

Against Spacetime,rimitively assessed as the readout of some specific material clock. The redundant abstraction of a macroscopic spacetime organizing all our particle detections is unproblematic and extremely useful in the classical-mechanics regime. But I here observe that in some of the contexts where quantum mecha
