Can wormhole inside a black hole become an escape?
I did not major in Physics so not sure if this is a proper question; but according to some Google search there do exist papers discussing wormhole inside black hole like this, which I am not able to ...

Understanding Wormholes Geometrically
Is the folding sheet analogy really that good for understanding what a wormhole is? After all, space-time curvature doesn't require any ambient space (it's intrinsic), as such a picture would suggest. ...

Would a Wormhole exclude the creation of another wormhole in the warped space?
In this typical depiction of a wormhole, spacetime is folded to make the two distant areas closer together. Would that mean the "crest" of the "fold" in spacetime is incapable of ...

Replica wormholes in $AdS_5 \times S^5$ holography
I have a question about replica wormholes and the CFT ensembles in AdS/CFT. To make sure that my question isn't coming from a simple misunderstanding, I'll first sketch out my current understanding on ...

What’s the condition to form an astrophysical wormhole?
According to GR, what’s the mechanism for a star to form a wormhole? How is it different from collapsing to a black hole? What’s the energy scale required?

Limit of gravity
Is there any limit to the bending of spacetime due to gravity?
I have been reading about wormholes and how they bend spacetime and connect two systems. But if there is no limit to gravity, we can ...

What modifications/corrections are made by $f(R)$ gravity model on Morris-Thorne wormhole metric?
What modifications/corrections are made by the $f(R)$ gravity model on the Morris-Thorne wormhole metric? Specifically, how does the physics associated with the metric change in $f(R)$ gravity compare ...

MP and RN Spacetime in Intra-Universe Wormhole Metric
I want to make sure I correctly understand what this paper is saying. It sounds like it is talking about a two-body Majumdar-Papapetrau outer metric that switches to RN once you enter either of the ...

Precise formulation of the ER = EPR conjecture
Maldacena and Susskind have "formulated" the now famous ER = EPR conjecture in their paper Cool horizons for entangled black holes, but as of today, I have not find a quantum theorist who ...

Negative Energy and Gravity
Why do many science communicators say that negative masses fall upwards? Is it the same in the physics literature that they say that negative masses fall upwards?
In general relativity, things don't ...

Could information be transferred through a wormhole?
There was a paper published recently about the possibility of sending messages through a wormhole,see reference here. It has also been speculated that any entangled pair of particles—even particles ...

Will this hypothetical circular singularity FTL travel warp drive work? [closed]
Not a physicist, but just wanted to know if this would work in theory:
Since nothing can practically travel faster than the speed of light (for now until proven otherwise), the only way for ...

Do certain quasi-particles really have negative mass?
Do phonons for example really have negative mass or does it just seem like they have negative mass? Could one use the negative mass of certain quasi particles to meet the negative energy requirements ...

Is an Einstein-Rosen Bridge theoretically required to have matching Schwarzchild radii on either end?
Is there a solution where the mouths on either end can have a different radius? I am also curious about these types of requirements in the case of a multi-mouth wormhole. Thanks for your time.

How can dense quark matter stabilize wormholes?
I have read in several articles, such as
https://www.sciencedirect.com/science/article/abs/pii/S0577907323000266 and https://arxiv.org/abs/1403.0771 that dense quark matter can stabilize wormholes. ...
