On Wednesday, scientists leading an international project called the Event Horizon Telescope will release their latest findings in what’s expected to be a historic reveal
In space, black holes are massive objects with gravity so strong that they can bend space and time to the breaking point.
The telescope is not a single instrument but a collaboration involving radio observatories around the world, including facilities in Hawaii, Chile, Europe and at the South Pole. “It’s a special moment,” said Avery Broderick, a researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ont., who has been with the project for more than a decade and is set to join his colleagues for what is expected to be a historic reveal.
Radio waves from the hot gas surrounding the black holes are a different matter. Researchers with the Event Horizon Telescope have already confirmed that they can detect these signals. Now the question is whether they can be mapped with enough precision to create a picture – and what that picture will reveal about the extreme environments surrounding black holes, where the more bizarre aspects of Einstein’s theory of general relativity are working at full force.
