“The fate of black holes in a quantum theory of gravity is, in my view, the most important problem in theoretical physics,” said Jorge Pullin, the Horace Hearne professor of theoretical physics at LSU.
Dark energy has been described as everything from a fifth force to a new form of matter, but so far, no direct evidence has been found of its existence. “I have absolutely no clue what dark energy is,” says Noble Prize winning physicist Adam Riess . “Dark energy appears strong enough to push the entire universe – yet its source is unknown, its location is unknown and its physics are highly speculative.”
“We actually saw this decay happen. It’s the longest, slowest process that has ever been directly observed, and our dark matter detector was sensitive enough to measure it,” said Ethan Brown, an assistant professor of physics at Rensselaer Polytechnic Institute about a process that takes more than one trillion times longer than the age of the universe. “It’s amazing to have witnessed this process, and it says that our detector can measure the rarest thing ever recorded.”
“Humans are strange…We are the aliens,” observes Columbia University astrophysicist, Caleb Scharf, noting that humans are a striking anomaly in the natural world. “We also have a truly outsize impact on the planetary environment without much in the way of natural attrition to trim our influence (at least not yet).
Editor, Jackie Faherty, astrophysicist, Senior Scientist with AMNH. Jackie was formerly a NASA Hubble Fellow at the Carnegie Institution for Science. Aside from a love of scientific research, she is a passionate educator and can often be found giving public lectures in the Hayden Planetarium. Her research team has won multiple grants from NASA, NSF, and the Heising Simons foundation to support projects focused on characterising planet-like objects. She has also co-founded the popular citizen science project entitled Backyard Worlds: Planet 9 which invites the general public to help scan the solar neighbourhood for previously missed cold worlds. A Google Scholar, Faherty has over 100 peer reviewed articles in astrophysical journals and has been an invited speaker at universities and conferences across the globe. Jackie received the 2020 Vera Rubin Early Career Prize from the American Astronomical Society, an award that recognises scientists who have made an impact in the field of dynamical astronomy and the 2021 Robert H Goddard Award for science accomplishments.
Astronomers have discovered a new, bizarre type of cosmic object, ORC J0102–2450, while using the Australian Square Kilometer Array Pathfinder telescope. The colossal object is now the third odd radio circle (ORC) that is invisible to all wavelengths of light except radio with an elliptical galaxy at its geometrical center.
Without mind, there might as well be nothing. Colin McGinn at the University of Miami, believes that no matter how much scientists study the brain, the mind is fundamentally incapable of comprehending itself. “We’re rather like Neanderthals trying to understand astronomy or Shakespeare,” McGinn observed in Consciousness and Space. Human brains suffer from a “cognitive gap” in understanding their own consciousness.”
