Black holes cannot be created by light
July 26, 2024• Physics 17, 119The formation of a black hole from light alone is allowed by general relativity, but a new study says quantum physics rules it out. D.…

Supermassive black holes provide ‘hearts and lungs’ that help galaxies live longer
The lives of galaxies can be extended if their supermassive black holes provide them with "hearts and lungs" to keep them "breathing" and prevent them from getting too big.That's the…
Study Finds Black Holes Made of Light Impossible – Challenges Einstein’s Theory of Relativity
New research shows that extreme objects known as "kugelblitzes" - black holes formed only by light - are impossible in our universe, a challenge Einstein's general theory of relativity. The…
Billion-mass behemoths: Surprisingly massive black holes in the early universe challenge cosmic theories
Artist's impression of the bright core region of a quasar, an active galaxy. The supermassive black hole at the center is surrounded by a bright disk of gas and dust.…
Space simulation reveals how black holes grow and evolve
This image from the simulation shows a supermassive black hole, or quasar, surrounded by a rotating disk of material called an accretion disk. Credit: Caltech/Phil Hopkins group A team of…
Forbidden black holes and ancient stars lurk in these ‘little red dots’ (image)
Forget the "little green men" - it's the "little red dots" in the infant universe that caught the eye of the James Webb Space Telescope (JWST). The strange red bodies,…
The lack of black holes in the Milky Way is bad news for this dark matter theory
Scientists have discovered that unusually massive black holes appear to be absent from the Milky Way's diffuse outer halo. The discovery could spell bad news for theories that suggest that…
Black holes and dark revelations: Gravitational waves provide new clues about the composition of dark matter
Artist's impression of a microlensing event caused by a black hole viewed from Earth toward the Large Magellanic Cloud. Light from a background star located in the LMC is bent…
Can black holes be created from pure light? New paper challenge theory.
Squeeze enough stuff into one place, space-time itself will wrinkle into a sweet cosmic kiss known as a black hole.As far as Einstein's sums are concerned, these "things" include the…
