“I was quite surprised by how simple the story hiding behind the curtain of complexity in the data,” Sneppen continued. “You have this immensely complex physics, unimaginable dense stars and the birth of a black hole — and then it all reduces to this beautiful sphere.”
The neutron stars that crashed into each other are “dense and compact,” Sneppen said. They only measured around 20 km in diameter — about 12 miles — but they are “heavier than the sun,” he said. “A teaspoon of neutron star matter weighs more than Mount Everest.”
…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.
“The most energetic outflow came from a quasar called SDSS J1042+1646 with 5×1030 gigawatts, or 5 million trillion trillion gigawatts. For perspective, a nuclear reactor puts out about one gigawatt of energy, while the total energy of all Milky Way stars is about 1028 gigawatts.”
Tired of corona-related news. Time to relax with a completely science-based, “you are somewhat insignificant in the greater scheme of things” post.
