SUMMARY

The discussion centers on the concept of a "perfect vacuum" within a sealed container and its implications in spacetime physics. Participants explore the contents of such a vacuum, with one contributor suggesting that a vacuum is not merely empty but rather a complex state filled with potential. The conversation also delves into the idea of a vessel propelled by a controlled black hole, which could create a wormhole effect, allowing for instantaneous travel across the universe. This thought experiment raises questions about the nature of vacuums and black holes, challenging traditional definitions and encouraging deeper exploration of these concepts.

PREREQUISITES
  • Understanding of basic physics concepts, particularly in spacetime and vacuum theories.
  • Familiarity with black hole mechanics and their theoretical implications.
  • Knowledge of wormhole theories and their potential applications in science fiction.
  • Background in mechanical or industrial engineering principles related to propulsion systems.
NEXT STEPS
  • Research the properties of black holes and their role in modern physics.
  • Explore the concept of wormholes and their theoretical feasibility in astrophysics.
  • Study the implications of vacuum states in quantum mechanics.
  • Investigate the intersection of science fiction and theoretical physics in literature.
USEFUL FOR

Science fiction writers, physicists, and enthusiasts interested in the complexities of spacetime, black holes, and the philosophical implications of vacuums in the universe.

Thought experiment for discussion:
You have a sealed transparent container with a "perfect vacuum" inside of it. 1) List what is inside of the "empty" container. 2) Explain how you might go about expelling EVERYTHING from the container.

LOL. It's necessary for you to post your thoughts (and links to your reading) so we know what your background is. There are several different ways to answer your question, so the more you can tell us about your thoughts on this, the better.

A perfect vacuum -
An existential crisis,
For spacetime physics?

Not reading, but writing. My background is in industrial/mechanical engineering. I'm retired and have begun writing a science fiction anthology. Throughout it, I would like the reader to be wondering if the plot is actually happening or if it is all taking place inside of the protagonist's head due to a neurological disorder. (Shades of "A Beautiful Mind") Due to this and the fact that it is a work of fiction, I am able to forego probability and even plausibility to some extent, but not possibility.

My reasoning behind my queries has to do with something that will come to fruition near the end of this anthology. It will be a vessel that will be propelled/expelled by a controlled black hole in front of the vessel, pulling it forward, while simultaneously transferring that space/time around the vessel (creating a wormhole) to the rear of the vessel. The controlled dispersion of this causality will then also push the vessel forward. Eventually, the vessels creator and pilot will discover that they can instantly travel to any point in the universe while also staying in the same place.

In consideration of this, I attempted to put a black hole into its simplest terms. To me, this would be a "space/time vacuum". And of course, this led me to the questions of "is the word 'vacuum' too simplistic in this context?" and "how could something like this possibly by formed on a small and controllable scale?".

Well, I think at any layman level it would be the exact opposite of 'vacuum' (which is in fact can be a quite complex and active thing too): it is an area which were stuffed full - and then were stuffed some more till it could not bear it any more.

If 'vacuum' can be connected to black holes, then it's rather the lack of our knowledge, not the lack of ... stuff :wink:
