Carlo Rovelli: Where does the stuff that falls into a black hole go?

THERE is an incomprehensible thing in what we think about dark openings. They have now become “typical” objects for cosmologists. Stargazers notice them, check them and measure them. They act precisely as Einstein’s hypothesis anticipated a century back, when nobody envisioned that such exceptional items could really exist. In this way, they are leveled out. Furthermore, still, they remain totally baffling.

From one perspective we have a delightful hypothesis, general relativity, affirmed in fantastic way by cosmic perceptions, which accounts entirely well for what the cosmologists see: these beasts that swallow stars spin in vortices and produce monstrously incredible beams and other mischief. The universe is astonishing, variegated, loaded with things that we had never anticipated or envisioned the presence of, yet intelligible. Then again, there is as yet a little inquiry of the sort that kids work in when grown-ups are excessively excited: “However where does all the material that we see falling into a dark opening go?”

Furthermore, this is the place where things become troublesome. Einstein’s hypothesis gives an exact and exquisite numerical depiction even of within dark openings: it shows the way that material falling into a dark opening should follow. The matter falls ever quicker until it arrives at the main issue. And afterward… at that point the conditions of Einstein lose all importance. They presently don’t disclose to us anything. They appear to soften like snow in daylight. The factors become boundless and nothing bodes well. Ouch.

What ends up making a difference that falls into the focal point of the opening? We don’t have the foggiest idea.

Through our telescopes we see it falling, and we intellectually follow its direction until it almost arrives at the middle, and afterward we have no information on what occurs straightaway. We understand what dark openings comprise of, both outside and inside, yet an essential detail is feeling the loss of: the middle. Yet, this is not really a unimportant detail, since all that falls in (and into the dark openings that we see in the sky, things keep on falling) wraps up at the middle. The sky is loaded with dark openings into which we can see things vanish… yet we don’t have the foggiest idea what happens to them. Read more
