Could Mysterious Black Hole Burps Rewrite Physics?

These explosions, called extreme nuclear transients, shine for longer than typical supernovas and get 30 to 1,000 times as bright.

Astronomers have identified a new kind of cosmic explosion extreme nuclear transients so powerful they outshine typical ...

Black holes are invisible, yet they are among the brightest things in the universe. ... Second, the light from a black hole flare will reveal a spectrum unlike that of a dying star.

If these black holes lie close enough together, ... this one also predicts the characteristics of the resulting flares astronomers might see through telescopes.

“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 ...

Aside from being the most powerful known explosions in the universe, ENTs can help astronomers learn more about monster black holes in faraway galaxies. That's because the incredible brightness of ...
