A new kind of hidden black hole may explain the mystery of dark energy

Space-time may hide a bizarre new kind of black hole that causes Einstein鈥檚 theory of gravity to fail 鈥� and could solve the mystery of dark energy

An artistic celebration of the Dark Energy Spectroscopic Instrument (DESI) year-one data, showing a slice of the larger 3D map that DESI is constructing during its five-year survey. By mapping objects across multiple periods of cosmic history with extremely high precision, DESI is allowing astronomers to make unprecedented measurements of dark energy and its effect on the accelerating expansion of the Universe. DESI???s map reveals the large-scale structure of the Universe, showing clumps of galaxies separated by voids where there are fewer objects. This pattern is a result of large pressure waves that permeated the early Universe and is reflected in the cosmic microwave background ??? a 2D snapshot of the radiation that filled the Universe shortly after the Big Bang, which bears the imprint of the 3D galaxy distribution. DESI is mounted on the U.S. National Science Foundation Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF NOIRLab. This version of the DESI map includes 600,000 galaxies ??? less than 0.1% of the survey's full volume. The locations of objects in the data slice do not correlate with their locations on-sky shown in this image.
