Can a white hole turns into a black hole?
I have been trying to read Penrose diagram to understand what white hole can do, but can the white hole collapses into a black hole and if so then what kind of conditions would turn a white hole into ...

Does a white hole forms accretion disk?
A white is time reversal of a blackhole at least mathematically, I know it can't exist but may I know if it can form accretion disc similar to those stellar mass black holes. Does it spins on it's ...

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 are white holes described as outgoing spacetime and still have attractive gravity?
White holes are described by the time reversed Schwarzschild metric. A test particle which is gravitationally attracted to the black hole's event horizon in the Schwarzschild metric is also ...

Distinction between behavior of spacetime inside a black hole during evaporation and the phase of transition to a white hoöe, in Loop Quantum Gravity
I was just watching: Carlo Rovelli (2023). What is a white hole? The Royal Institution (YouTube).
Rovelli mentions at 36 minutes that the transition to a white hole state is more likely than ...

White Holes Evidences
It is well known that in the canonical quantization program for quantum gravity, like LQG/Wheeler-De Witt/Polymer QM,
almost every prescription when applied to cosmology/gravitational collapse leads ...

What would happen if you threw an object (a tennis ball for example) at a white hole? [duplicate]
I know white holes are hypothetical but IF they were real, what would happen if you threw an object at the white hole ? will the object get repelled as soon as it gets close to the white hole or will ...

Seeking Visualization Tools for Hypothetical Black Hole Concept
I have a idea I'd like to explore: If a black hole can bend light due to its immense gravitational attraction, could we imagine an 'inverted black hole'? In this hypothetical scenario, this object ...

Why are there two interior regions in this diagram?
Why are there two interior regions in this diagram? There seems to be two inner horizons, and two wormhole regions.
Where do the two such regions comes from? What determines which reason someone falls ...

Where do the other black holes in this diagram come from?
In this Penrose diagram for a charged/Rotating black hole, once your in the new universe you can continue onward to an infinite sequence of black holes/white holes.
So I'm asking, where do those black ...
