The Unraveling of Space-Time. ““One sees no alternative except to say that [space-time] geometry fails, and pregeometry has to take its place to ferry physics through the final stages of gravitational collapse and on into what happens next.”

    *What’s wrong with space-time as we know it? Physicists point to a constellation of scenarios, including ones that pit the tenets of general relativity against those of quantum theory — the other pillar of 20th-century physics, which describes matter and radiation as collections of randomly rippling waves. Einstein pioneered the use of thought experiments to sharpen his ideas about space and time. When today’s physicists imagine sufficiently fantastical procedures, they encounter conundrums that undermine their common sense notion of space-time as a fundamental fabric.*
