In 1916, German physicist Karl Schwarzschild outlined a solution to Albert Einstein\u2019s equations of general relativity, in which the center of a black hole consists of a so-called singularity, a point at which space and time no longer exist. Here, the theory goes, all physical laws, including Einstein\u2019s general theory of relativity, no longer apply; the principle of causality is suspended.<\/p>\n<p>This constitutes a great nuisance for science\u2014after all, it means that no information can escape from a black hole beyond the so-called event horizon. This could be a reason why Schwarzschild\u2019s solution did not attract much attention outside the theoretical realm\u2014that is, until the first candidate for a black hole was discovered in 1971, followed by the discovery of the black hole in the center of our Milky Way in the 2000s, and finally the first image of a black hole, captured by the Event Horizon Telescope Collaboration in 2019.<\/p>\n<p>In 2001, Pawel Mazur and Emil Mottola proposed a different solution to Einstein\u2019s field equations that led to objects that they called gravitational condensate stars, or gravastars. Contrary to black holes, gravastars have several advantages from a theoretical astrophysics perspective.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The interior of black holes remains a conundrum for science.
