Saturday Quote: When the universe is young and cute. Plus: Southern Ocean cooling trends explained

One of the strangest facts in computer science is that it is really difficult to generate true random numbers. Anyway, on a computer. I can do it well: 173, 401, 530. It’s true randomness from the very top of my mind. Scientist: If you need random numbers, please contact us by email day or night. However, a multicenter group of researchers reports using a 56-squit quantum computer to generate “proven certified randomness.” Frontier studies in marine science report evidence of deep ecological outcomes after the disappearance of great white sharks from the false bays of South Africa. And in fact, in great medical news, a team from McMaster University discovered a new class of antibiotics.

Furthermore, researchers believe that the climate modeling could not predict the 40-year cooling trend in the South. Astronomers have reported new techniques for finding hidden black holes. And researchers have produced the deepest image of the cosmic microwave background to date.

Modified model

Climate models have long predicted warming in the South Seas, so the cause of progressive cooling trends over the past 40 years has been a mystery. Stanford University researchers believe these models could not explain the amount of meltwater and underestimated rainfall.

As temperatures rise, the ice sheet melts and precipitation increases, resulting in less salinity in the upper layers of the southern ocean as freshwater infiltration. This means that water is less dense and that researchers will create what describes a mixture of warm water as a lid that blocks the cold water from the deep sea to the surface. This dynamic was not expressed in climate models predicting warm Southern Oceans.

Researchers also found that location is important in cooling dynamics. Sea surface temperatures in the south were sensitive to freshwater flow along the coast rather than widespread rainfall. Earl Wilson, assistant professor of Earth Systems Science at Stanford, said, “Applying freshwater near the Antarctic edge has a major impact on sea ice formation and the seasonal cycle of the sea ice range, which has a downstream effect on sea surface temperature.

Baby Universe, Part 1

An international team of scientists recently detected a mysterious radio signal in 12.9 billion light years of hot gas and dust clouds. You know there’s something there. Maybe you’re thinking about some things that is. There are some clues and previous knowledge that can probably be applied.

Using Atacama’s large millimeter array, researchers made the most insightful observations of hot molecular gas clouds in history, determining that laundry kittens were the super-large black holes in which the universe was in childhood 12.9 billion years ago. Ultra-high resolution observations allowed us to observe heating mechanisms that affect gas within just a few hundred light years from black holes, representing a new technique for finding similar objects. Radio waves detected by Alma are not absorbed by dust or gas, making the instrument uniquely powerful to detect black holes.

Furthermore, this study suggests that there may be a huge population of dust and gas-encapsulated black holes. Researchers intend to apply similar techniques to identify similar black holes.

Baby Universe, Part 2

Using the power of the Atacama cosmological telescope, an international research team spent four years generating the most accurate image of the universe in its early stages, an image of the background of the cosmic microwave 12.9 billion years ago. The new measurements provide a sophisticated estimate of the age of the universe around 13.8 billion years ago.

Furthermore, the measurements reaffirm one of two conflicting measurements that physicists call Hubble tension. Measurements of cosmic microwave background consistently yielded a universal expansion rate of 67-68 km per second per megapulsec. Measurements derived from nearby galaxies show expansion velocity between 73 and 74 km/s/mpc. New observations again confirm the lower rate.

“We were able to measure more accurately than ever, which includes 1,900 ‘Zetta-suns’, or nearly as mass as the two Trion Trion Sands,” said Professor Arminia Calabrese, director of the Department of Physics and Astronomy at Cardiff University.
