James Webb’s ‘Black Hole Stars’ Raise a Bigger Question: Could Black Holes Lead to Other Universes?

The James Webb Space Telescope is uncovering objects in the early universe that astronomers did not expect to see.

Among the strangest are what researchers have begun calling “black hole stars” — enormous, star-like objects containing rapidly growing black holes buried inside incredibly dense envelopes of gas.

They aren’t ordinary stars.

Instead of being powered by nuclear fusion, their tremendous energy appears to come from matter falling toward a black hole hidden deep inside the surrounding gas.

And that leads to an obvious question:

Where does all that gas eventually go?

Much of it may ultimately become part of the black hole itself.

As gas falls inward, it is compressed and heated to extreme temperatures. Some material can be thrown outward by radiation and powerful outflows, but material that crosses the event horizon adds its mass and energy to the black hole.

The black hole grows.

That process may help explain one of the biggest mysteries James Webb has created since it began looking deeper into the early universe:

How did supermassive black holes become so enormous so quickly?

Growing a Monster

Scientists already knew black holes could grow by consuming gas, dust and stars and by merging with other black holes.

Given billions of years, that makes sense.

The problem is that Webb is finding massive black holes that existed when the universe was still extremely young.

Some appear to have grown far faster than traditional models predicted.

A black hole born inside an enormous reservoir of dense gas could have an advantage: instead of waiting for material to wander nearby over billions of years, its food supply would already surround it.

That could potentially allow an early black hole to grow at a remarkable rate.

One of the clearest recent examples is MoM-BH*-1. A peer-reviewed Nature paper published August 12, 2026, describes the source as it appeared about 660 million years after the Big Bang. Modeling cited by MIT suggests a central black hole of roughly 100,000 solar masses surrounded by a dense hydrogen cocoon roughly the size of the solar system.

NASA has also reported strong evidence for the same general “black hole star” scenario in another object, GLIMPSE-17775, where Webb spectroscopy revealed more than 40 spectral lines consistent with a rapidly accreting black hole buried in dense gas.

But once we start talking about matter disappearing across an event horizon, another question becomes unavoidable.

Where Does the Matter Actually Go?

From outside a black hole, we can observe what happens right up until the event horizon.

Beyond it, things become much more mysterious.

Classical general relativity predicts that matter falling into a black hole ultimately approaches a singularity — a region where density and spacetime curvature become so extreme that our existing physical theories can no longer completely describe what happens.

That does not necessarily mean physicists know that matter simply reaches a point and stops.

It means our current theories become incomplete.

And that has led physicists to explore stranger possibilities.

What If a Black Hole Doesn’t End Spacetime?

Imagine matter collapsing under its own gravity.

A black hole forms.

Spacetime becomes increasingly curved.

But instead of everything terminating at a singularity, suppose the geometry of spacetime somehow continues.

Perhaps it undergoes a quantum “bounce.”

Perhaps it opens into another region of spacetime.

From our side, we would see a black hole.

But from the hypothetical other side, that new region could be expanding.

And that raises one of the strangest possibilities in cosmology:

Could a black hole give birth to another universe?

Scientists do not currently have evidence that this happens.

But versions of the concept — including baby universes, gravitational bounces and new regions of spacetime forming through extreme gravitational collapse — have been explored theoretically.

What If We’re Inside One?

Take that idea one step further.

Our own universe is expanding.

And because of that expansion, there are cosmic horizons beyond which events can never communicate with us.

That is not the same thing as a black hole event horizon. Scientists have good reasons for distinguishing the two.

But the similarity creates an extraordinary thought experiment.

What if what looks like a black hole from one universe could look completely different from inside?

Suppose a black hole formed in a larger “parent” universe.

Beyond its horizon, instead of terminating at a singularity, spacetime expanded into a new region.

To observers living there, that expanding region might simply appear to be their universe.

They might have no way to cross the boundary and discover what existed before it.

And then their universe would eventually produce stars.

Those stars would create black holes.

Some of those black holes might create additional universes.

The result would be something resembling a cosmic family tree:

Universe → black holes → new universes → new black holes → more universes.

There is currently no evidence proving that this is how reality works.

But there is also an enormous amount about the interior of black holes — and the quantum nature of gravity itself — that physics has yet to explain.

James Webb Is Opening the Door to Bigger Questions

James Webb has not discovered another universe.

It has not discovered a wormhole.

And it has not demonstrated that we are living inside a black hole.

What it has done is uncover objects from the early universe that challenge some of our previous assumptions about how quickly black holes could form and grow.

The proposed “black hole stars” are part of that mystery.

And as scientists figure out how these objects formed, grew and eventually disappeared, they may get closer to answering an even deeper question.

We increasingly understand what happens to matter before it enters a black hole.

What happens after it crosses the event horizon remains one of the greatest unanswered questions in physics.
