Dr Özel said the new image’s similarity to that of 2019 demonstrated that the previous image was no coincidence. In an interview, Peter Galison, a physicist and historian at Harvard and a member of the collaboration, noted that the black hole M87 was 1,500 times more massive than that of the Milky Way; typically in physics or astronomy, when something increases by a factor of 10 or more, everything changes. “The similarity on such a huge scale is amazing,” said Dr Galison.

At Thursday’s press event, Michael Johnson, a member of the team and also of the Harvard-Smithsonian Center, said, “This is an extraordinary verification of Einstein’s theory of general relativity. “

Black holes were an undesirable consequence of the general theory of relativity, which attributed gravity to the warping of space and time by matter and energy, in the same way that a mattress sags under a sleeper.

Einstein’s insight led to a new conception of the cosmos, in which spacetime could quiver, bend, tear, expand, swirl, and even disappear forever into the maw of a black hole, an entity with a gravity so strong that not even light could escape. this.

Einstein disapproved of this idea, but the universe is now known to be dotted with black holes. Many are the remnants of dead stars that have collapsed in on themselves and continued to advance.

But there seems to be a black hole at the center of almost every galaxy, including ours, which may be millions or billions of times more massive than our sun. Astronomers still don’t understand how these supermassive black holes got so big.

Paradoxically, despite their ability to swallow light, black holes are the most luminous objects in the universe. Materials – gas, dust, jagged stars – falling into a black hole are heated to millions of degrees in a dense maelstrom of electromagnetic fields. Some of this material falls into the black hole, but some is thrown out by enormous pressures and magnetic fields.
