'Immortal Suns', a documentary about stars that feed on dark matter

Our knowledge of the universe is growing, but it is still very small compared to the vast amount of things we don't know.

Among these enigmas are the two elements that make up 95% of the universe: dark energy and dark matter. These are elements that do not emit, reflect or absorb light and whose existence we deduce from their gravitational effects. Dark matter is said to be the most abundant element, accounting for perhaps 85% of the matter in the universe. About this matter, NASA points out:

"There is no more important problem in cosmology today than dark matter. Dark matter is composed of particles that do not absorb, reflect, or emit light, and therefore cannot be detected by observation of electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effects it has on objects that we can observe directly."

In June 2024, research was unveiled on some puzzling stars at the heart of our Milky Way galaxy. These objects, called S cluster stars, could be feeding on dark matter, which would give them a kind of cosmic immortality, causing very old stars to display the characteristics of young stars.

These stars would accumulate a large amount of dark matter, which is denser in that region of our galaxy. Isabelle John, leader of the team that did that research at the Kavli Institute for Particle Astrophysics and Cosmology, told Space.com:

"Our simulations show that stars can survive on dark matter alone as fuel, and because there is an extremely large amount of dark matter near the Galactic Center, these stars become immortal," John added. "This is quite fascinating because our simulations show similar results to the observations of S-cluster stars: Dark matter as a fuel will keep stars forever young."

On this fascinating question, the YouTube channel Melodysheep published another of its excellent videos on Thursday, trying to capture in images something that is difficult to explain since it involves stars that are fed by invisible matter:

You can see here some screenshots from this video, which poses a somewhat curious hypothesis in its final part.
