Does a Space Warp Bubble Move Through Space or Does Space Move Around It?

Click For Summary

Discussion Overview

The discussion explores the concept of a hypothetical space warp bubble and whether it would move through space or if space itself would move around it. The scope includes theoretical implications and speculative reasoning related to concepts in physics, particularly in the context of faster-than-light travel and the nature of space-time.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant proposes that if a bubble could be created separate from the universe's space-time, it might allow space-time to move around it, creating the illusion of movement through space.
  • Another participant expresses uncertainty about the feasibility of the concept, suggesting it may border on "not possible" and likens it to the Alcubierre drive.
  • A different participant clarifies that while we perceive light moving at the speed of light, our actual movement through space is much slower, citing the Earth's rotational speed.
  • A repeated point emphasizes the speculative nature of creating such a bubble, suggesting that the idea may exceed the bounds of known physics.

Areas of Agreement / Disagreement

Participants do not reach a consensus, with some expressing skepticism about the feasibility of the concept while others explore its implications. The discussion remains unresolved regarding the nature of movement in relation to the proposed bubble.

Contextual Notes

Limitations include the speculative nature of the bubble concept, dependence on definitions of space-time, and the challenge of remaining within established physical laws.

If you were able to create a bubble that was separate from this universe space/time, would that bubble if standing still allow space/time to move around it thus making it appear as if you actually moved through space, even though space/time moved around you. Since we are moving thru space at 2.7 million MPH, would the 'bubble' move that fast without having actually directly moved?

We're not moving at the speed of light. We're in an awkward situation where light bounces off of us that fast but we're moving at 746ft per second or whatever the rotational speed of the Earth is.

That is a mighty big if, so big that I think you have stepped outside the bounds of known physics. On this board we must stay within those bounds.
