Hairy Black Holes Explain Hawking’s Paradox, Physicists Claim

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 signature feature of black holes is that they are black — objects which fall into the hole can no longer be seen and can no longer influence the outside Universe. In classical general relativity, ‘no hair’ theorems severely restrict the properties of a black hole which can affect other objects. These are limited to its total mass, spin, and charge. Now, four theoretical physicists show that these properties no longer hold when quantum...

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb’s optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment, known as fine phasing, each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of a star called 2MASS J17554042+6551277 uses a red filter to optimize visual contrast. Image credit: NASA / STScI.

This Hubble image shows NGC 1097, a barred spiral galaxy some 48 million light-years away in the constellation of Fornax. The color image is made up of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys in the ultraviolet, near-infrared, and optical parts of the spectrum. Seven filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Noise variations in the two regions covered by the second data release from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey with the coverage of the 841 individual pointing outlined. The RA-13 (top) and RA-1 (bottom) regions span 4,178 and 1,457 square degrees and have median rms values of 74 μJy beam−1 and 106 μJy beam−1 respectively. Failed facets (white regions) are generally caused by either poor ionospheric conditions or dynamic range issues around bright sources such as 3C 48 and 3C 196.
