![]() Wormholes present a lot of problems, Farah said. ![]() I have a feeling that being close to a black hole would not be healthy."Īnd while the next installment of Fortnite did not start with a journey through a wormhole ( Chapter 2 Season 2 is all about secret agents, gold and the Midas touch), that'd also be a heavy dose of science fiction. I don't know what that would do medically to you. If you, you could probably get into an orbit maybe close enough where you can counteract some of the gravitational force if you are moving fast enough. If we go down too far in the ocean, you start having health problems pretty quickly. ![]() You know, we're not really built for pressure. "The gravity, even at that range, would be like ridiculously strong. Yeah, I don't think you'd have much of a chance," Farah said. "If you were close enough to the black hole to sort of see that Fortnite image, I think you probably wouldn't survive. Surprise: You can't survive near a black holeĪnd it might go without saying, but a human being could not survive being that close to a black hole. It's something that we want to test more." "We sort of have an idea, but we don't understand it fully. "How these wisps form and what they mean about the magnetic field of a black hole is actually a strong point of debate," Farah added. "The wisps themselves are the direct result of the magnetic field, of the magnetic turbulence around the black hole," Farah said. As material gets closer to the black hole, it speeds up, then heats up, causing the glowing region around the black hole. "It was surprisingly accurate," Farah said.įor example, the wisps around the Fortnite black hole appear in actual EHT simulations. So then, how accurate is the Fortnite black hole? Significantly increasing the longest baseline would have a big impact on their image resolution, because you make the lens of EHT much wider than what the telescope network currently has. By sending VLBI spacecraft into orbit, researchers can potentially double, triple or quadruple the baseline, or the distance between two telescopes in the array. The collective telescopic network has a "lens" the size of planet Earth. One way to make the image less fuzzy is by using satellites into space to collect observations via VLBI, or very long baseline interferometry.Ĭurrently, EHT works as a worldwide collaboration of radio telescopes. (Image credit: EHT Collaboration)Īnd with the help of some additional gadgets, the picture of a black hole could have a higher resolution. The Event Horizon Telescope, a planet-scale array of eight ground-based radio telescopes forged through international collaboration, captured this image of the supermassive black hole and its shadow that's in the center of the galaxy M87. By comparing future data to the original image, they can test the functionality of the telescope. ![]() One year later, M87 continues to be very important for the EHT team. The iconic first image of a black hole features the behemoth M87, a gravitationally-dense structure which harbors about 6.5 billion times more mass than Earth's sun. For example, by assuming Einstein's theory of general relativity to be true, researchers can ascertain information about the black hole, like its mass and inclination, Farah said. And when they develop models, they make assumptions about the physics of a black hole to then learn details about the object. When researchers try to create an image, they assume nothing and work to create a true picture from the data. Two areas of focus for Farah are imaging and modelling. So, he knows a thing or two about what black holes look like. He was part of the team that produced the first-ever image of a black hole in 2019, and he continues to collaborate with the project, known as the Event Horizon Telescope. Joseph Farah is a research fellow at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
