According to the prevailing inflationary universe theory, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of the infant Universe and produced all known matter. That ancient energy shared key features of the current Universe’s dark energy. If you ask yourself the question, ‘Where in the later Universe do we see gravity as strong as it was at the beginning of the Universe?’ the answer is at the center of black holes. It’s possible that what happened during inflation runs in reverse, the matter of a massive star becomes dark energy again during gravitational collapse — like a ‘little Big Bang played in reverse.’ New research is strengthening the case for this scenario with recent data from the Dark Energy Spectroscopic Instrument (DESI).
