My previous attempt at a rocket with no propellant, would seem to create momentum and energy out of nothing, it the rocket is now moving.

Not likely. We just have not considered what happens to the pair of temporary particles that have been reflected out the back of the space craft.

It must leave behind some permanent negative mass and momentum, which is rather strange.

Filling up space with 'debts'.  Or possibly cancelling out some previous 'credits'

Vacuum seems to become a complicated banking system, like bit coins, with a strange universal ledger.

- Space is full of pairs of particles being formed and destroyed.
- if you grabbed a pair and chucked them out of the back of your space ship, you would propel yourself in the other direction. You might only need to reflect then in the right direction.
- hey presto, you have a rocket with no propellant.

Actually you had propellant, but it disappeared from whence it came.

There might be ripples in the froth of the vacuum, so the conservation of momentum might not be broken

The idea that you can interpret the uncertainty principle of position and momentum as an uncertainty principle of energy and time and then as borrowing possibility for a bit of energy for a bit of time is wonderful for filling a vacuum with a fuzz of particle pairs and leaking energy from a black hole.

But I have never heard how this is meant to be spread out relative to mass and time, or space and momentum.

Nor whether this could be a lending operation rather than a borrowing operation.

Could the effect be bigger near a large mass? Or slow time?

Could there be regions where the total borrowings are really large?  It is asking questions about the overall balance sheet ratios.

Could this be dark matter and dark energy?

Could the strange thing be the things that don't appear to be borrowed or lent, but actually owned outright?

Borrowing would be at least one quantum of time, and give an idea of the largest amount that can be borrowed, but where and when?
