Ten overhyped physics and astronomy claims from 2023, reports Big Think, including: Astronomers found the Universe’s first stars; Dark matter is wave-like in nature; JWST’s distant galaxies disprove the Big Bang; The Universe is actually 26.7 billion years old; and, Exoplanet K2-18b is an inhabited ocean world.
How fast is gravity, exactly? probes Big Think. Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity: that Thanks to observations of gravitational waves recorded in 2017, we now know that gravity and light travel at the same speed.
How Could The Big Bang Arise From Nothing? Explores Alastair Wilson at the University of Birmingham. "some cosmologists believe a previous, cold dark empty universe like the one which lies in our far future could have been the source of our very own Big Bang."
Conversations With an Alien—For a recent study published in the peer-reviewed journal PeerJ, scientists from UC Davis, the Alaska Whale Foundation, and SETI (Search for Extraterrestrial Intelligence) teamed up."In a landmark experiment, the team had a 20-minute conversation with a humpback whale named Twain in her own language."
Was The Christmas Star A Real Astronomical Event?--The “Star of Bethlehem” is a surprisingly small element of the Christmas story, and yet possible real astronomical events have been put forward as an explanation.
What Does Winter Look Like On Other Worlds?--No two planets in the Solar System have similar seasons, so time for a round-up of how they look, reports Stephen Luntz. "The best guide to how seasons might operate on planets within the habitable zone of other stars is to look at the diversity of our own Solar System, which certainly reveals there are lots of ways things could pan out."
'Lost City' Deep in The Ocean Is Unlike Anything We've Ever Seen Before on Earth, reports Science Alert. "Discovered by scientists in 2000, more than 700 meters (2,300 feet) beneath the surface, the Lost City Hydrothermal Field is the longest-lived venting environment known in the ocean. Nothing else like it has ever been found."
