Can Matter Be Transferred Between Universes?

Click For Summary

Discussion Overview

The discussion revolves around the speculative question of whether matter can be transferred between different universes. Participants explore the implications of such a concept, considering definitions of "universe" and the nature of isolated systems.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if matter can be transferred between universes and whether our universe has a mechanism for such transfer.
  • Another participant asserts that the concept of "other universes" is speculative and lacks evidence, suggesting that the question may not have an answer.
  • A different participant reiterates the initial question and proposes that an isolated system is a suitable framework for understanding the universe.
  • One participant expresses a personal inclination to speculate about the existence of multiple universes, acknowledging the historical inaccuracies in our understanding of the cosmos and suggesting that energy transfer between universes could be a possibility, albeit without proof.
  • Another participant discusses two definitions of "universe," one as a closed system based on measurable effects and the other as the entirety of three-dimensional space across time, referencing a theory about colliding universes.
  • There is a mention of basic particle physics existing in "Hilbert Space," which could imply limitations on exchanges with other three-dimensional planes due to the nature of dimensional constraints.

Areas of Agreement / Disagreement

Participants express differing views on the speculative nature of the question, with some emphasizing the lack of evidence for multiple universes while others entertain the possibility without reaching consensus.

Contextual Notes

The discussion highlights limitations in definitions of "universe" and the speculative nature of the topic, with unresolved assumptions about the nature of dimensionality and isolated systems.

i wish to know if matter can be transferred from one universe to other universe? does our universe have valve like thing to let the matter in or out of the system?

"Other universe" is highly speculative and is not supported by ANY evidence so your question has no answer.

I think an isolated system is the correct way of thinking about it.

What he said, but I sometimes like to speculate that there are many Universes, since the beginning of time we've been wrong about much of the Universe, and when I like to think about it, I say why not, it could be a possibility (Don't count on my words because there is no proof for this), we used to think there was just the solar system, but nope there's billions which is probably an understatement! Also then we discovered that we live in an island of stars which is our galaxy, that was only 1 of billions! So I like to think, why can't there be more than 1 universe or even billions, where they can transfer energy from one universe to the other!

Anyways, I'm getting ahead of myself and phinds has answered your question.

There are two ways of defining "universe". One is anything that we can measure or affect. So, by that definition, the universe is a closed system.

Another way to define the universe is to say that it is the entire three-dimensional space across all of time. That what you're thinking of when you ask your question. I recall one alternate theory to the Big Bang that posits two 3D universes colliding.

From what I read, most basic particle physics seems to live in "Hilbert Space" with as many dimensions as you need. This would argue against little exchanges with other 3D planes - since whatever is holding us to 3D would likely collapse any matter local to our 3D space back into our space right away.
