Universe has Entropy > 10^104

New physics calculations have upgraded the Entropy quotient of the universe from a “hold” to a “sell”…

…the collective entropy of all the supermassive black holes at the centers of galaxies is about 100 times higher than previously calculated. Because supermassive black holes are the largest contributor to cosmic entropy, the finding suggests that the entropy of the universe is also about 100 times larger than previous estimates, the researchers reported.

Most of the lost data came from.. what else? overlooking the bigger pictures:

New data… included a fuller range of the masses of supermassive black holes rather than just using the average mass. “The upshot was that much more entropy is contributed by a smaller population of much larger, 1-billion-solar-mass black holes,” Egan says.

Low entropy thresholds are important for a lot of effects, from keeping time flowing forward, to ensuring a timely heat death for all. It also makes non-chaotic space music more likely than john cage:
