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

ANALOGY. “First let us show the deep similarities between the problem of quantum gravity and turbulence.” https://lnkd.in/eA85pA5X View in LinkedIn

FROTHY EARLY TIMES. “So, was spacetime turbulent in the early universe? To this question we now sketch a positive response.” https://lnkd.in/eA85pA5X View in LinkedIn

TURBULENT FROTH. “Nevertheless one important aspect of the early Universe appears to be missing in HFC. It is connected to the expectation (supported by Wheeler’s insight) that, due to quantum fluctuations, spacetime, when probed at very small scales, as is the case for the early universe, will appear very complicated —- something akin in complicity to a chaotic turbulent froth.” https://lnkd.in/eA85pA5X View in LinkedIn

WONDERLAND UNDERPINNINGS. “Everything we call real is made of things that cannot be regarded as real. If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.” (Niels Bohr). https://lnkd.in/ewqarGvD View in LinkedIn

ORIGINS OF MATTER. “Let us follow the folklore: at the end of inflation, the energy stored in the quanta of spacetime foam would be converted into hot ordinary particles (as well as dark matter).” https://lnkd.in/eA85pA5X View in LinkedIn

SCALE ILLUSTRATED. “The interesting thing about the human scale is that both gravity and electromagnetism are very significant for us in our everyday lives, whereas the weak and strong nuclear forces are of marginal concern (except in certain parts of modern technology).” https://lnkd.in/e-atRRat View in LinkedIn

DEDUCTIONS. “We conclude with two observations the first of which involves the crucial question of whether our approach yields enough e-folds of inflation to solve the myriad of cosmological problems.” https://lnkd.in/eA85pA5X View in LinkedIn

INVERSE RELATION. “These two ways of measuring are ‘dual’ to each other in the mathematical sense that the greater the energy, the smaller the distances that can be resolved.” https://lnkd.in/e-atRRat View in LinkedIn
