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 …
Unifying gravity and quantum mechanics without the need for quantum gravity | Physics World
Source: Unifying gravity and quantum mechanics without the need for quantum gravity – Physics World Stochastic framework In his study, Oppenheim builds on this idea to develop a new stochastic framework for coupling the quantum and classical-gravity worlds. Since these worlds have fundamentally different rules, Oppenheim’s theory uses separate statistical theories for each of them. …
New Theory Unites Einstein’s Gravity With Quantum Mechanics | Scitechdaily.com
A new approach seeks to unify quantum theory with classical General Relativity. The testable assumption here is to probe masses with unprecedented accuracy in order to find out, whether or not random fluctuations in the tested results point to a quantum nature of spacetime or a classical one. So far, the scientsts seem to be partial to the idea that classical systems "infect" quantum systems, a situation otherwise also known as "decoherence", which has a quantum system break down and the information be lost as soon as it interacts with the classical universe around it.
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.

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 …

Astrophysicist Katie Mack Explains the Significance of the Famous James Webb Telescope Photo | NewsObserver
Source: Astrophysicist ‘AstroKatie’ Mack shares what she sees in the James Webb telescope photo It may not be readily apparent what's so spectacular about the first images that the James Webb Space Telescope captured and so it might be helpful to hear a renowned astrophysicist convey it to us in – more or less – …
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.
