TERRESTRIAL VALIDATION. “The equivalence principle therefore states that the relative strength of gravity and electromagnetic forces is always the same. This principle has been tested to high accuracy both on the Earth and in satellites orbiting the Earth, and no discrepancy has yet been found.” https://lnkd.in/e-atRRat View in LinkedIn

EQUIVALENCE. “But in the end his theory of general relativity was based instead on the ‘equivalence principle’, that gravitational mass and inertial mass are the same thing.” https://lnkd.in/e-atRRat View in LinkedIn

THE ISSUE OF MASS. “A similar problem affects the concept of mass, in the foundations of general relativity. Einstein originally took as his starting point the ‘general principle of relativity’, that is, the principle that the laws of physics are the same for all observers.” https://lnkd.in/e-atRRat View in LinkedIn

NEW SUBSTITUTION. “Everything that can be explained with spinors can be explained with spacetime instead. Thus it is not only desirable, but almost certainly essential, to abandon the concept of a spinor altogether.” https://lnkd.in/e-atRRat View in LinkedIn

THE VESSEL. “This means that ordinary space and time are sufficient to explain this initially surprising property of electrons, protons and neutrons.” https://lnkd.in/e-atRRat View in LinkedIn

CONTAINED SPIN. “That image provides a model for how electrons, protons and neutrons ‘spin’— something is ‘holding on’ to them. That something, I maintain, is the rest of the universe, and the way it is holding on is by the various forces of nature, most importantly electromagnetism, but also including gravity.” https://lnkd.in/e-atRRat View in LinkedIn

SEATED IN FOAM. “We have sketched a scenario in which both the late and the early cosmic accelerations have a common origin and can be traced to spacetime foam.” https://lnkd.in/eA85pA5X View in LinkedIn

HYPOTHETICAL DARK ENERGY. “This scenario is very similar to that of quintessence, but it has its origin in the holographic spacetime foam.” https://lnkd.in/eA85pA5X View in LinkedIn

FLUCTUATIONS AND FROTH. “This interpretation of the Kolmogorov scaling in the quantum gravitational setting implies that the quantum fluctuation phase of strong quantum gravity in the early Universe could be governed by turbulence.” https://lnkd.in/eA85pA5X View in LinkedIn

QUANTUM GRAVITY AND FROTH. “The connection between them can be traced to the role of diffeomorphism symmetry in classical gravity and the volume preserving diffeomorphisms of classical fluid dynamics.” https://lnkd.in/eA85pA5X View in LinkedIn
