Nature's Deepest Secrets May Be Unknowable to Are Supernovae a Good Place to Hunt for Alien Broadcasts?
Supernovae might be a good place to hunt for alien broadcasts--Other intelligent civilizations may send transmissions after a bright galactic event like a supernova to make them more visible to others, according to SETI researchers, reports New Scientist.
Could Black Holes Be Used As Tools For Quantum Computing By Advanced Extraterrestrial Civilizations asks Keith Cowing for Astrobiology. "This offers a new avenue for SETI, including the civilizations entirely composed of hidden particles species interacting with our world exclusively through gravity.
The case for a parallel universe going backwards in time--To explain the cosmos without invoking cosmic inflation, physicist Neil Turok has proposed the existence of a mirror-image universe going backwards in time from the big bang. He tells us why the idea is so compelling, reports New Scientist.
The James Webb Telescope detected the coldest ice in the known universe – and it contains the building blocks of life, reports JoAnna Wendel for Live Science. The JWST's latest observations of icy molecules will help scientists understand how habitable planets form.
"Could nature's deepest secrets be unknowable to us?"--Einstein’s quantum ghost is here to stay: To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so, reports Marcelo Gleiser for Big Think.Â
Role of Stress in the Origin of Life, reports Keith Cowing for Astrobiology. "The article shows the compatibility of the concept of thermodynamic inversion (TI) of the origin of life with the theory of stress in (micro)biology."
Decoding the Pentagon’s latest UFO report--How to think about recent information on UAPs, or Unidentified Aerial Phenomena, reports Popular Science. "The report, mandated by the National Defense Authorization Act for 2022, includes the work of the All-Domain Anomaly Resolution Office, or AARO, which was originally created within the Department of Defense in 2020 as the Unidentified Aerial Phenomena Task Force.
What Time Is It on the Moon?--Satellite navigation systems for lunar settlements will require local atomic clocks. Scientists are working out what time they will keep. reports Elizabeth Gibney, Nature magazine via Scientific American.
A New View of the Most Explosive Moon in the Solar System--Recent strange activity around Jupiter’s volcanic moon, Io, confused and excited scientists, reports New York Times Science.Â
Life on Io? An astrobiologist says it’s possible, reports Paul Scott Anderson for Earth & Sky. "Some scientists are rethinking the possibility of life on this hostile world. It would most likely be underground, if it ever existed. Astrobiologist Dirk Schulze-Makuch recently wrote about his own perspective on this intriguing idea in Big Think on January 13, 2023."
Astronomers inspect a powerful radio-loud high-redshift quasar, reports Tomasz Nowakowski for Phys.org.
‘Forbidden’ planet somehow escaped consumption by its dying host star--The planet 8 Ursae Minoris b should have been destroyed when its star became a red giant, but it continues to orbit strangely close to the star, reports New Scientist.
Physicists should take time to ponder the strangest ideas--There are other ways to explain wave-particle duality than Albert Einstein's, but we don't teach them. Excluding the conceptual challenges of quantum mechanics from the classroom limits our students, says Chanda Prescod-Weinstein for New Scientist.
These five spectacular impact craters on Earth highlight Earth's wild history, reports Phys.org.
