White holes are sometimes seen by the inhabitants of Zalonia. They appear as sudden explosions, and the medes don’t really understand them much. There is a science to it, though:

There are white holes found in space that create explosions and disappear immediately, kind of the opposite of black holes. From afar, White Holes look exactly like black holes. It is like a time reversal from a black hole. It is impossible to enter a white hole. Objects from a white hole can interact with objects on the outside, but nothing can interfere with the white hole. Only the Soul Chaser knows what they are. There is a theory that black holes turn into white holes when they die. This may happen when the black hole gets so small that it no longer obeys the common-sense rules of stars and billiard balls. Quantum randomness takes over and transforms the black hole into a white hole. Some think the white hole might explain the Big Bang.

There is also a theory that white holes are on the opposite side of a black hole. In other words, when something is sucked into a black hole, it explodes out from a white hole in a different part of the universe, or a parallel universe.

White holes could experience a belch. It is described as a black hole’s “time reversal,” a video of a black hole played backwards. Nothing can enter a white hole. Things can leave the white hole, but because nothing can get in, the interior is cut off from the universe’s past: No outside event will ever affect the inside. It would be like a singularity in the past that can affect everything in the outside. In a black hole, the outside universe can influence the inside of a black hole’s horizon, but the interior can’t affect the exterior. No one knows how a white hole might form. Playing a video backwards of a black hole doesn’t make physical sense.

If white holes did form, they probably wouldn’t exist for long. Any outgoing matter would collide with the matter in orbit, and the system would collapse into a black hole.

There is a question of what happens to the internal record when a black hole evaporates away? General relativity won’t let the information out, and quantum mechanics forbids its deletion.

Some think that a white hole is the death of a black hole, but that would violate the general relativity equations. Maybe the black hole grows so small that it no longer obeys the common-sense rules of stars and billiard balls. Quantum randomness takes over, and the black hole transforms into a white hole.

A while hole, similar to a mass to a human hair, wouldn’t have the gravitation of a black hole but would hold all the information swallowed in a previous life. Too small to attract orbiting matter, the white hole might remain stable enough to eventually spit out all the information accumulated by its forerunner. This means that white holes could dominate the universe one day.

The Big Bang’s explosion of matter and energy looks like potential white hole behavior. They are even mathematically identical at times.

White holes appear in the theory of eternal black holes. There are no observed physical processes through which a white hole could be formed. Supermassive black holes might be at the center of all galaxies, and Hawking and others have proposed that these supermassive black holes spawn a supermassive white hole. Hawking argued that the time reversal of a black hole in thermal equilibrium results in a white hole in thermal equilibrium (each absorbing and emitting energy to equivalent degrees).

White holes are predicted as part of a solution to the Einstein field equations known as the maximally extended version of the Schwarzschild metric, describing an eternal black hole with no charge and no rotation. Here, “maximally extended” refers to the idea that the spacetime should not have any “edges” for any possible trajectory of a free-falling particle (following a geodesic) in the space time, it should be possible to continue this path arbitrarily far into the particle’s future, unless the trajectory hits a gravitational singularity like the one at the center of the black hole’s interior. In order to satisfy this requirement, it turns out that in addition to the black hole interior region that particles enter when they fall through the event horizon from the outside, there must be a separate white hole interior region, which allows us to extrapolate the trajectories of particles that an outside observer sees rising up away from the event horizon. The Einstein-Rosen bridge can either connect two black hole event horizons in each universe (with points in the interior of the bridge being part of the black hole region of the spacetime) or two white hole event horizons in each universe (with points in the interior of the bridge being part of the white hole region). It is impossible to enter the bridge, though.

Here is a little for you science nerds:

Some researchers have proposed that when a black hole forms, a Big Bang may occur at the core/singularity, which would create a new universe that expands outside of the parent universe (Fecund universes).

A 2012 paper argues that the Big Bang itself is a white hole. It further suggests that the emergence of a white hole, which was named a “Small Bang”, is spontaneous—all the matter is ejected at a single pulse.
In 2014, the idea of the Big Bang being produced by a supermassive white hole explosion was explored in the framework of a five-dimensional vacuum by Madriz Aguilar, Moreno and Bellini

For white holes to exist, there can’t be a single speck of matter within the event horizon.

Loop quantum gravity

In theory, a black hole singularity would compress down until the smallest possible size predicted by physics. Then it would rebound as a white hole. But because of the severe time dilation effect around a black hole, this event would take billions of years for even the lowest mass ones to finally get around to popping.

WHAT WHITE HOLES ARE IN ZALONIA

• White holes don’t just release matter…
• They release possibilities, timelines, and broken pieces of reality

WHAT THEY ACTUALLY DO

1. Reality Spill Points

Effect:

White holes eject things that don’t belong

• creatures from unknown realms
• fragments of other timelines
• objects that shouldn’t exist

2. Time Fracturing Zones

Effect:

Time becomes unstable near a white hole

• moments repeat
• people experience future memories
• time speeds up or slows down

Danger:

Someone could:

• age rapidly
• relive the same moment endlessly

---

3. Memory and Identity Distortion

Effect:

White holes don’t just affect reality—they affect minds

• people remember things that never happened
• identities begin to blur
• someone might “remember” another life

Creepy angle:

Two people might remember being the same person

---

4. Raw Magic Eruption

Effect:

White holes flood the world with unfiltered magic

• spells become wildly powerful
• magic mutates unpredictably

Danger:

• magic users lose control
• spells gain unintended effects

 5. World Alteration Events

Effect:

Land itself changes

• forests grow overnight
• mountains crack open
• new ecosystems appear

👉 reality is rewritten locally

 6. “Observers” Are Drawn to Them

Effect:

White holes attract:

• powerful beings
• unknown watchers
• possibly your gnonows

Lore idea:

Some entities don’t want the white holes to stay open

---

THE BIG RULE

White holes are unstable—and eventually collapse.

When They Collapse:

• everything they released becomes unstable
• creatures may vanish
• people may disappear
• entire areas may reset or distort

RARE EVENT: WHITE HOLE STORM

Multiple white holes appear at once:

• reality breaks across regions
• time fractures everywhere
• magic becomes uncontrollable

This could be a major series-level event
