Nobel-Prize laureate Subrahmanyan Chandrasekhar, for whom NASA’s Chandra X-Ray Observatory was named, described black holes as “the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.”
Strange Cosmic Paradoxes
These strange cosmic paradoxes, which Princeton quantum physicist John Archibald Wheeler coined “black holes,” have no memory, yet are said to contain the earliest memories of the universe, as well as the most recent, while at the same time obliterating all memory by obliterating all its manifestations.
And yet, like a hologram, black holes have two dimensions, in which gravity disappears, but they reproduce an object in three dimensions, aligning with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical, and smooth, as they appear in the famous image of the black hole in M87 captured by the Event Horizon Telescope (EHT) in April 2019. An image, EHT director Shep Deleman described as “one-way doors out of the Universe.”
