ANALOGY. “First let us show the deep similarities between the problem of quantum gravity and 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

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

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

SPECIFICALLY. ‘The case for dark energy in the current/recent (“late”) universe was proposed before, while the case for cosmic inflation in the early Universe is the main focus of this Letter.” https://lnkd.in/eA85pA5X View in LinkedIn

RIVERS AND RIPPLES. “A physical system is described by an operator. The eigenvalue of the operator contains only partial information of the system. This is the reason why one cannot hear the shape of a drum. Nevertheless, the information embedded in eigenvalues, though partial, is of special importance.” https://lnkd.in/gMu-_FxR View in LinkedIn

OCCAM’S RAZOR. “One attractive feature of our present proposal is that the scheme is very economical, involving no arbitrary or fine-tuned parameters.” https://lnkd.in/eA85pA5X View in LinkedIn

CONSEQUENCES. “It is also natural in that inflation was inevitable as turbulence set off by the Planckian dynamics was inevitable in the early Universe.” https://lnkd.in/eA85pA5X View in LinkedIn

NONLOCAL FOAM. “The scheme also provides a rationale for why inflation lasted only briefly (say, ∼ 10(−33) sec.) as the turbulent phase was quickly terminated due to the nonlocal (extended) property of the quanta of spacetime foam.” https://lnkd.in/eA85pA5X View in LinkedIn
