The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

A new paper from Harvard's sometimes controversial physicist Avi Loeb has suggested that if we want to find advanced alien ...

Researchers have observed strange goings-on around a supermassive black hole located nearly 300 million light years away.

A new generation of black hole research is unfolding thanks to artificial intelligence, massive simulations, and cutting-edge ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

Specifically, they state that a black hole with a mass of 2.2 x 10 19 pounds (10 22 grams) would leave a hole 0.1 micron in size, large enough to be seen with a regular optical microscope.

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

From a piece of cloth that may have belonged to Alexander the Great to an image of our galaxy's central black hole, here's our pick of controversial science stories in 2024.

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light- years.
