This weekend’s stories include: the universe isn’t locally real until the largest asteroid that hit earth was twice the size of the rock that killed the dinosaurs, until dormant bacterial cells could help us awaken extraterrestrial life, and more more.
The universe is not locally real, and the physics Nobel laureates proved it, reports Scientific American. Elegant experiments with entangled light have unearthed a deep mystery at the heart of reality. “The evidence shows that objects are not only affected by their environment and may also lack certain properties before being measured. As Albert Einstein famously lamented to a friend, “Do you really think the moon isn’t there when you’re not looking at it?”
A black hole’s orbiting ring of light could encrypt its inner secrets– Physicists have discovered that the ring of photons orbiting a black hole exhibits a special kind of symmetry, suggesting a deeper meaning, reports Thomas Lewton for Quanta.com. “The photon ring, glowing orange in this visualization of light flowing around a black hole, contains a sequence of images from across the universe.”
Sinister Implications of Hawking Points – “Black Hole Corpses Before the Big Bang”
We might finally have evidence of the first stars in the universe, reports Science Alert. “The very first stars may have appeared when the universe was only 100 million years old, or less than 1 percent of its current age. Since then, the rapid expansion of space has obscured their light, forcing us to look to closer cosmic sources for evidence of their existence.”
The largest asteroid to ever hit Earth was twice the size of the rock that killed the dinosaurs, reports Harry Baker for Live Science. “The destructive space rock was somewhere between 12.4 and 15.5 miles across.”
The Chicxulub Impact – Has an ‘Impossible’ Magnitude 12 Earthquake Changed Our World?
Did aliens visit ancient Sumer?, asks Big Think. “Astrophysicist Carl Sagan considered the possibility that ancient humans might have recorded extraterrestrial visits. An ancient Sumerian account of the fish-like creature Oannes “deserves more careful study,” he wrote.
The Political Implications of the Discovery of Extraterrestrial Intelligence, reports IFL Science. “In 2020, a paper by Kenneth Wisian and John Traphagan suggested that there was a risk related to SETI evidence that had not previously been adequately studied. Wisian and Traphagen argued that the danger of discovery did not come from the aliens, but that the actual or perceived benefit of having access to this message could lead to earthly problems such as espionage, escalating conflicts between nations, and even ending in a total end War.”
“Coming Attractions” – Extraterrestrial Intelligence as Physics
Quantum physics forces us to make really strange choices. Einstein always loses in the quantum realm, Big Think reports. “Reality is truly ‘ghostly’, as Einstein feared. But what does this spookyness tell us? Nobody really knows. Any interpretation of quantum mechanics is forced to accept something about reality that seems really, really strange. “
The thinking undead: how dormant bacteria calculate their return to life, reports UC San Diego. Unexpected activity in dormant bacterial cells offers lessons for understanding life in extreme conditions on Earth and perhaps on other planets. “When conditions become favorable, spores that may have been dormant for years can wake up and come back to life in minutes.
These Undead Bacteria Cells Could Help Us Raise Extraterrestrial Life reports The Daily Beast. “Sleeping spores can exist and ‘count’ thousands of years without using any energy.”
A Physicist Explains the Science of Einstein’s “Spooky Action at a Distance”, reports The Conversation. “The 2022 Nobel Prize in Physics recognized three scientists who made groundbreaking contributions to the understanding of one of the most mysterious of all natural phenomena: quantum entanglement.”
Chinese scientists call for plan to destroy Elon Musk’s Starlink satellites reports Ben Turner for Live Science. “Chinese military researchers say Starlink could threaten China’s national security.”
“New Inflation” and the many worlds of the multiverse
Why the multiverse is the cinematic fantasy of our time –Very controversial theories of quantum physics rarely get airtime. But the idea that multiple, even infinite, universes coexist has caught on in movie theaters everywhere, reports CNN.
