You can think about it based on the uncertainty principle, which allows for borrowing energy for a limited time. The more energy you borrow, the less time you have. With a mass close to Rubidium, a virtual W boson can't survive for long, limiting the maximum travel distance significantly.

If the volume of all singularities is zero

Is it though?

How do you measure volume, if your ruler is being sucked inwards faster than the speed of light? How do you measure where the mass is if its world line ended at the singularity years ago?

What about other models for the internals of a black hole, which attempt to unify quantum mechanics? Does the world line actually form a loop at the event horizon?

We know that our understanding of the physics inside a black hole is probably wrong. Because it doesn't explain how quantum information is absorbed, then released when the black hole evaporates.

The wave of "stretch" passes us at the speed of light. But the rate of "stretch" is slow.

Picture a tank of water, 1m deep. A bouy on the surface, using pulses of sound to measure depth. A wave 1km wide passes the bouy, also at the speed of sound. The bouy could send 1000 pulses before the wave disappears.

The correct answer is to say, While everyone is presumed innocent until found guilty, _if_ these allegations against Minsky are true then Minsky needs to answer to them. Until _we_ know all of the facts, _we_ will be limiting our interactions with Minsky.

FWIW, Minsky was dead by the time the accusation and Stallman's statements were made.

Yes, but the bit Tesla battery is pugged into the wholesale layer of the network. Not at the street level where the problem is located. Solar power can't be shipped back up the grid, it must be consumed by your neighbours.

I have no sympathy for the network operators. This is an entirely foreseeable problem, that they should have been trying to solve for the last decade.

  • power has been too expensive for too long
  • people install solar to cut costs
  • power network threatens solar users, or raises prices elsewhere
