Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...

“ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that ...

Black hole bombs have been theorised and developed since 1971, and now one was finally - safely - created in the UK.

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

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

Scientists have discovered the most powerful blasts of energy in the known universe. Dubbed extreme nuclear transients, or ENTs, the cosmic explosions are unprecedented in their intensity.
