To my knowledge an alcubierre effect requires negative energy. If someone's invented something that behaves like negative energy why isn't that the headline? Warp drive is cool but it's a second-order consequence of what would be a physics revolution greater than relativity.
- eightysixfour 5y agoThe Casimir effect is already a known way of creating (locally) negative energy. See here: https://en.wikipedia.org/wiki/Negative_energy#Casimir_effect https://en.wikipedia.org/wiki/Negative_energy#Casimir_effect
- magicalhippo 5y agoI was under the impression the paper by Jaffe[1] showed the negative energy explanation[2] was not physical, but totally not my field.

- findalex 5y agoThis is what makes me think the warp drive is a no go here. The interactions between these surfaces are already described by QM without needing to appeal to negative energy.
- gizmo686 5y agoThe casimir effect is established physics that leads to negative energy densities on small scales
