Enormous Cryovolcanoes Spotted on Pluto

The Wright Mons region on Pluto: darker/lower albedo, redder patches exist primarily on north-facing slopes but there are also more subtle differences in albedo and redness across the region; the region labeled A represents a redder unit transition to less red units at lower elevation. The longitude and latitude extents of the image are 160-182°E and 13-31°S. Image credit: Singer et al., doi: 10.1038/s41467-022-29056-3.

Cryovolcanoes (ice volcanoes) are similar to normal volcanoes but instead of being formed from molten rock, they are made by frozen liquids like ammonia and water. The Wright Mons region on Pluto: darker/lower albedo, redder patches exist primarily on north-facing slopes but there are also more subtle differences in albedo and redness across the region; the region labeled A represents a redder unit transition to less red units at lower elevation....

Quantum scrambling is one suggestion for how information can fall into a black hole and come out as random-looking radiation. Perhaps, the argument goes, it is not random at all, and black holes are just excellent scramblers. Image credit: E. Edwards / Joint Quantum Institute.

The mass-energy-information equivalence principle proposed in 2019 and the information content of the observable matter in the Universe estimated in 2021 represent two important conjectures, called the information conjectures. Combining information theory and physical principles of thermodynamics, these theoretical proposals made specific predictions about the mass of information as well as the most probable information content per elementary particle. Dr. Vopson proposes an experimental protocol that allows for empirical verification of the information conjectures by confirming the predicted information content of elementary particles.
