“As we put more greenhouse gases into the atmosphere and temperatures rise, we are quickly rewinding the climate clock to climate states not seen in human history,” wrote acclaimed University of Wisconsin paleo-climatologist Jack Williams in an email to The Daily Galaxy. “We can expect that over the next few decades, climates will most resemble those of the warm Pliocene, roughly three million years ago, or perhaps even the hothouse Eocene, 50 million years ago.”
“Information,” wrote Arizona State University astrophysicist Paul Davies in an email to The Daily Galaxy, “is a concept that is both abstract and mathematical. It lies at the foundation of both biology and physics. ”
Dark matter is aptly named. It emits no light and interacts with visible matter only via gravity. But dark matter might be only the tip of an invisible universe of unknown forces. This possibility has led to a hunt for “dark photons.” Such photons are analogous to ordinary photons, but they are exchanged among particles of dark matter, and according to some models, they may have mass.
The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is one of the more intriguing discoveries. “Part of the thrill of science is stumbling across a mystery that is not easy to solve,” said Jun-Hui Zhao of the Harvard-Smithsonian Center for Astrophysics,. “While we don’t have the answer yet, the path to finding it is fascinating.”
Mars holds her secrets close, planetary-science experts have noted. The Red Planet is crisscrossed with the distinctive tracks of big, long-dead rivers, but we still don’t know what kind of weather fed them. Scientists aren’t sure, because their understanding of the Martian climate billions of years ago remains incomplete according to a ground-breaking 2019 study from the University of Chicago.
Another amazing week of discovery in the Cosmos, ranging from the mystery of our Universe’s beginning to a massive void detected in the Milky Way to the spooky implications of quantum-level technologies: “everything that can happen will happen, an infinite number of times.”
The discovery of black holes was the first collision of quantum gravity with general relativity. In 2019, astrophysicists at Western University found evidence for the direct formation of black holes that do not need to emerge from a star remnant. The production of black holes in the early universe, formed from massive seeds aided by gravitational fields soon after the Big Bang, provide scientists with an explanation for what appeared to be the anomaly of extremely massive black holes at a very early stage in the history of our universe.
