A strange black hole has appeared on Google Maps, and all kinds of conspiracy theories have emerged. The mystery has already been solved.
The gravitational field of the black hole bends the space around it, allowing the light to 'echo'. What does this detection mean? What is the role of Einstein's predictions in this discovery?
A group of researchers from Stanford University observe the light behind a black hole for the first time.
English physicist Stephen Hawking was right. As strange as black holes are, they seem to still adhere to some laws of physics.
