黑洞是如何诞生的？新发现让人吃惊_科技Science
black hole creation is crazier than previously thought, new observations reveal. over the course of just a few minutes, as a massive star dies and a black hole is born, multiple explosions cause the black hole to powerfully eject matter as well as greedily consume it.
it all starts with a gamma-ray burst – the most powerful type of explosion in the universe and an indicator that a massive star is dying in what astronomers call a hypernova.
a surprising chain reaction ensues as the black hole forms from the collapsed remains of the star. before these observations – made with nasa's swift satellite telescope, which specializes in gamma-ray burst detection – scientists believed that star death was a single explosion event.
