Dark Matter Could Be Responsible For Huge Black Holes at The Dawn of Time - ScienceAlert

cannot produce a massive enough seed black hole to accommodate newly observed supermassive black holes – unless the seed black hole experienced an extremely fast growth rate," Yu said.

"Our work provides an alternative explanation: A self-interacting dark matter halo experiences gravothermal instability and its central region collapses into a seed black hole.".

The team's scenario starts with the formation of just such a dark matter halo, coming together gravitationally in the early Universe.

This would cause the particles to slow, reducing angular momentum and shrinking the central halo so that, eventually, it would collapse under its own mass to form the seed of a black hole.

And, while the dark matter 'seed' can have a high enough mass to allow the black hole to grow quickly, both forms of matter are required.

This feature is exactly what we need to explain the origin of supermassive black holes in the early universe.

This should be able to help validate their model, a result that wouldn't just help us solve the problem of early Universe supermassive black holes, but the mysterious nature of dark matter
