Violations of the Achronal averaged null energy condition
Many energy conditions have been shown to be violated in the past in semiclassical gravity, for instance when considering Klein-Gordon quantum scalar fields. Victims include the WEC (Weak Energy ...

Alcubierre drive: what is the nature of exotic matter? [closed]
In connection with Alcubierre drive we often hear about necessity of an exotic matter in order to produce a negative energy density. I suspect that such matter has no place in standard particle model.
...

In regards to the hypothetical Alcubierre Drive (hear me out), are energy costs consumed immediately, or during transit?
I am aware the Alcubierre Drive is highly hypothetical and likely cannot exist. However, there are significant quantities of research material into Warp Drives of many types, and presumably the answer ...

Minimum amount of negative energy required in warp drive spacetimes
In the pioneering work of Alcubierre, to power a warp drive-like geometry it is necessary to employ an amount of negative energy larger (in absolute value) than the whole observable universe mass.
A ...

What are negative and positive energies? [closed]
So I have a few questions related to the negative and positive energy topic.
1)What do we mean by negative and positive energies in physics?
2)I have seen in a minute physics video that we need ...

Exotic matter out of a "squeezed" vacuum?
In the light of the current warp field experiments by NASA I found this paper:
https://arxiv.org/abs/1005.5682
Could this actually lead to the creation of exotic matter or at least strengthen the case ...

Exotic Matter -- What is it?
I have a conceptual understanding of some theoretical physics concepts, so without getting into the math, what is exotic matter?
I have read some articles that say it is anything not normal, while ...
