Space expansion, gravity waves, warp

Click For Summary

Discussion Overview

The discussion revolves around the propagation of gravity waves at the speed of light (c) and the theoretical concept of a warp drive that may allow for faster-than-light travel. Participants explore the implications of space expansion and the nature of gravity waves in relation to warp drive theories.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions how gravity waves can propagate at c while a theoretical warp drive wave might exceed this speed, referencing the future expansion of space between galaxies.
  • Another participant seeks clarification on what is meant by "theoretical warp drive wave," asking for references or links to support the claim.
  • A participant mentions the Star Trek warp drive and cites real-world research being conducted in the field, providing a link to an article about NASA's warp drive research.
  • A reference to the Alcubierre drive is provided, suggesting a theoretical framework for warp drive concepts.
  • One participant asserts that Star Trek is a work of fiction, implying skepticism about the applicability of its concepts to real-world physics.

Areas of Agreement / Disagreement

Participants express differing views on the validity of warp drive concepts, with some referencing theoretical research while others emphasize the fictional nature of popular media representations.

Contextual Notes

There are unresolved assumptions regarding the nature of gravity waves and the theoretical framework of warp drives. The discussion does not clarify the relationship between space expansion and the propagation of gravity waves.

If gravity waves are supposed to propagate at c, how could the theoretical warp drive wave propagate at greater than c values?
I have heard and red and understand that space itself can expand (and warp? ) faster than c and, in fact, that will happen in the future when space in between galaxy's will be expanding faster than c and the galaxy's will disappear from our observable universe, but, in that case, why would gravity waves only propagate at c ?

What "theoretical warp drive wave"? Can you give us a reference or link?
 
Sorry, but Star Trek is fiction.
