The Cosmic Gems is one of the most highly magnified objects in space, thanks to a phenomenon called gravitational lensing. (Image credit: ESA/Webb, NASA & CSA, L. Bradley (STScI), A. Adamo (Stockholm University) and the Cosmic Spring collaboration) Astronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin …
Mathematicians Attempt to Glimpse Past the Big Bang | Quanta Magazine
By studying the geometry of model space-times, researchers offer alternative views of the universe’s first moments. Source: Mathematicians Attempt to Glimpse Past the Big Bang | Quanta Magazine This is fascinating and highly promising research: A team of mathematicians take a closer look under which conditions a singularity might occur and have already identified a …

(Yiheng Lin/NIST/YouTube) Source: Physicists Conduct The Most Massive Test Ever of The Einstein-Podolsky-Rosen Paradox : ScienceAlert This is huge: Per above linked article physicists from University of Basel in Switzerland performed an experiment with two Bose–Einstein–Condensate clouds each 700 atoms strong in …
Quantum Theory’s ‘Measurement Problem’ May Be a Poison Pill for Objective Reality | Scientific American
A core mystery of quantum physics hints that objective reality is illusory—or that the quantum world is even weirder than expected.

Unraveling the Universe: Groundbreaking Measurement Shakes Up Physics
Source: Unraveling the Universe: Groundbreaking Measurement Shakes Up Physics The new results support the validity of the first of two discrepant ways of measuring the Hubble constant, which is the expansion rate of spacetime/our universe. What that means is indicative of a burgeoning suspicion among physicists that they need to rethink gravity, dark energy and …

The Big Bang no longer means what it used to | Big Think
Credit: Nicolle Rager FullerFrom a pre-existing state, inflation predicts that a series of universes will be spawned as inflation continues, with each one being completely disconnected from every other one, separated by more inflating space. One of these "bubbles," where inflation ended, gave birth to our Universe some 13.8 billion years ago, where our entire …

It takes three to tangle: Long-range quantum entanglement needs three-way interaction | phys.org
Source: It takes three to tangle: Long-range quantum entanglement needs three-way interaction Very "cool" (errm... or not, actually 🙂 )! A group of researchers from RIKEN Center for Advanced Intelligence Project found that quantum entanglement over long distances can only exist in a stable manner between at least three sub–systems. That more closely specifies …
What if the universe had no beginning? | Live Science
Causal set theory maintains that there may not have been anything like a "Big Bang" as the ultimate beginning of the universe, more like a discrete event some time into its evolution of current size and shape. In that way the universe always was and might go on forever.
