Almost every large galaxy still houses a monster black hole, up to billions of times the mass of our sun, at its center. They may have been among the universe’s earliest structures, influencing the formation and evolution of galaxies like our own. Black holes are connected to some of the most basic phenomena in our universe. Hamilton’s work has the flavor of a charming personal obsession, but it also has huge implications. He pictures a waterfall of space and time pouring over the event horizon to an inner zone where “all the light and material that ever fell into the black hole piles up in a tremendous collision, generating a maelstrom of energy and an infinitely bright, blinding flash of light.” Then he jumps in his barrel and takes the plunge. Where other scientists see the end point of scientific inquiry, Hamilton sees the beginning, an entrée to an extraordinary and unexplored terrain. As with Las Vegas, what happens in a black hole stays in a black hole. Since no energy, and hence no information, can ever leave that dark place, it seems quixotic to try peering inside. ![]() At the center is a core, known as a singularity, that is infinitely small and dense, an affront to all known laws of physics. Once trapped inside, nothing-not even light-can escape. A black hole’s outer boundary, known as the event horizon, is a point of no return. It’s fun to try to beat the odds.”īlack holes are massive objects that have collapsed in on themselves, creating a gravitational suction so intense that their insides become cut off from the rest of the universe. “I don’t necessarily avoid things others consider crazy, or I never would have gotten started in this black hole business. Hamilton, an athletic 59-year-old with a mane of sandy blond hair, brushes such doubt away. That quest has been called mad or just plain futile by colleagues who insist that the inner structure of the black hole is so extreme that it lies not only beyond exploration but beyond comprehension. I’m focused on attaining a complete understanding of the interior of black holes,” he says, his British accent adding solemnity and power to his words. “I’m not religious, but I share with religious people a desire to understand the truth about our universe. For 15 years the astrophysicist has ventured nearly alone into the darkest, most impenetrable part of the universe: the inside of a black hole. ![]() Hamilton rides in on his Cannondale mountain bike.įollowing his own path is not just a pastime to Hamilton, it is the essence of his career. On a blustery day like today, most of his colleagues arrive in SUVs or at least in cars shod with all-season tires. The vast disparity in the gravitational pull between your head and toes allows you to curl into a spaghetti-like noodle when you reach the black hole’s event horizon.It is late December and snow is swirling as Andrew Hamilton coasts up to his office at the University of Colorado’s Boulder campus, in the foothills of the Rockies. A human dropping through a black hole will arrive at the event horizon-the black hole’s edge from which not even light would escape and where gravity is so intense that light would circle the black hole as planets surround stars-much faster than if the black hole were smaller. Since supermassive black holes are significantly larger than stellar and intermediate black holes, their constituent components are more distributed widely. ![]() That’s because supermassive black holes have peculiar mechanics that result in a mix of gravity and event horizon that doesn’t immediately drag a person into a dead slice of pasta. In a recent article in The Conversation, Grinnell College physicists clarify that “A human can do this only if the respective black hole is supermassive and isolated, and if the person entering the black hole does not expect to report the findings to anyone in the entire Universe”. ![]() What’s the catch? If you jump into a black hole, don’t hope to return to our world any time soon. Scientists believe that humans will investigate black holes firsthand, according to a new discovery ripped from Interstellar.
