Today’s stories include The UFO whistleblower and the search for extraterrestrial life and Does space-time have a memory?
We Could Be Living in a Holographic Universe, a Cosmologist Says–This holographic concept could explain a mystery about black holes, but the math may not represent reality, reports Popular Mechanics. “Some physicists claim that our universe is merely an illusion, a product of quantum machinations happening in a lower-dimensional setting—in other words, a hologram.”
The UFO whistleblower and the search for extraterrestrial life–After David Grusch’s testimony to the US Congress this week, is it OK to talk about aliens? explores Henry Mance, award-winning Chief Features Writer at the Financial Times. “Grusch left open the possibility that the visitors were not strictly aliens, but intra-terrestrial beings — who had always lived with us on Earth — or inter-dimensional beings from another physical dimension.”
Whistleblower testimonies did not change our basic understanding of UFOs, reports PBS. “David Fravor was a commander in the U.S. Navy in 2004, stationed on the USS Nimitz, when he and another pilot saw an object behaving inexplicably. He described objects with no visible means of propulsion carrying out sudden maneuvers that no known technology could achieve.
Stars with superpowered magnetic fields could narrow the search for alien life, reports Robert Lea for Space.com–“Stars experiencing this enhanced magnetism are likely going to be battering their planets with high-energy radiation.”
Does space-time remember? The search for gravitational memory–Detecting the permanent imprints left by colliding black holes would reveal a universe saturated with infinite symmetries – and narrow the possibilities for a theory of quantum gravity, reports New Scientist.
The Most Surprising Discoveries in Physics–Experts weigh in on the most shocking, paradigm-shifting findings in the history of physics from Black Holes to Dark Energy, reports Scientific American.
NASA’s Voyager 2 Is Out of Contact but Not Lost in Space reports Katrina Miller for the New York Times. “On Tuesday morning, officials from the Deep Space Network, a global system used to operate numerous active space missions, detected a carrier signal from Voyager 2. That means the spacecraft is still broadcasting, though the signal is too weak for transmitting data.”
Newton’s first law appears to break down in the quantum realm–Newton’s first law of motion says that particles move in straight lines unless influenced by a force but a new experiment shows that the quantum version of that assumption fails for quantum particles of light, reports New Scientist.
