III. Two Regimes of Common Time

Connecting the independent Carrollian times at each point in space with large scale common time of everyday experience and the small scale common time…

II. Toward Carrollian Quantum Gravity

Trying to combine GR and QM in a way that doesn't assume the Planck length

I. Loopholes and workarounds

A "motivation slide" for a potential path to reconciling GR and QM that doesn't assume the existence of the Planck scale

Look. General Relativity is Weird.

It makes quantum mechanics seem practically staid by comparison.

Is Hawking radiation imaginary?

I mean obviously, in a practical sense, it's unobservable; however, what if it's not even an observable in the hand-wavy world of theoretical physics?

Why exactly do we need black holes to satisfy the 2nd law of thermodynamics in finite time?

“No, let’s not assume that.”

Has the past 50 years of black hole physics been a bunch of nonsense?

Growing skepticism of not just the Planck length but GR + QM

What does the Bekenstein bound bound?

Relevant length scales and relevant degrees of freedom

Planck scales aren't always small

Also: another take on the source of indivisibility

Hilbert space dilation and garbage bits

An interesting analogy with quantum circuits. Plus some other observations.

Clocking and shifting in Carrollian time

Ye olde tricke for turning a (discrete) circle into a commutator

More hand waving about quantum mechanics

It might be better characterized by arms flailing wildly like an air-driven tube man
