The cyclical cosmological model: “No empirical evidence supports any of the theory’s essential components.”
Cosmology
George Ellis argues: We can’t know if the universe had a beginning
Well, if the universe did not have a start, it must always have existed. And that’s the dreaded territory of Hilbert’s Hotel and infinity apart from mathematics.
At Phys.org: Can cosmic inflation be ruled out?
“If the Cosmic Gravitational Background were detected, clearly this would rule out the entire cosmic inflation paradigm, which does not allow for its existence.”
At SciTech Daily: Supernova Explosions Reveal Precise Details of Dark Energy and Dark Matter
“Supernova Explosions Reveal Precise Details of Dark Energy and Dark Matter.”
At Mind Matters News: Why it’s difficult for science to answer some basic questions
We can only research and see what happens, as the questions science is expected to answer grow more basic and more profound.
From IAI News: How infinity threatens cosmology
Peter Cameron writes: “Infinity is back. Or rather, it never (ever, ever…) went away. While mathematicians have a good sense of the infinite as a concept, cosmologists and physicists are finding it much more difficult to make sense of the infinite in nature.”
At SciTech Daily: Surprising New Features of Mysterious Fast Radio Bursts Defy Current Understanding
“An international team of scientists reveals an evolving, magnetized environment and surprising source location for deep-space fast radio bursts – observations that defy current understanding.”
At Reasons.org: Did the initial findings of the JWST repudiate the big bang creation model?
Hugh Ross: “To most people using their naked eyes, the heavens don’t seem to be declaring anything at all. But through space telescopes, they are proclaiming the wonders and beauty of God and his creation to a degree never before seen.”
At Evolution News: How Do We Know the Age of the Universe?
Physicist Rob Sheldon writes: A correspondent asked me recently how we know the age of the universe. The answer is calculated from the inverse of the Hubble constant. That is, if the galaxies are moving away from us at 72 km/s /Mpc, that has units of 1/time, the inverse is the age of the universe (more Read More…
At Reasons.org: Do the James Webb Telescope Images Show the Big Bang Didn’t Happen?
“The latest JWST images don’t justify the enormous attention Lerner’s model has recently received in the public sphere.”
At Quanta: How the Physics of Nothing Underlies Everything
“Why is there something rather than nothing?”
Do Natural Explanations Rule Out the Universe’s Fine-Tuning?
Astrophysicist Jeff Zweerink writes some thoughts on cosmological fine-tuning.
Here’s the European Space Agency’s 3-D map of over a billion stars
ZME Science: The catalog features multiple types of data, which means it can be used by astronomers working in different fields to understand the evolution of stars in our galaxy (and stars in general).
Nautilus: Gravitational Waves Continue to Astound
Professor Perkowitz: “Seven years after their discovery, the ripples in spacetime have opened new windows on the universe’s deepest secrets.”
Sabine Hossenfelder: The big problem with quantum theory is chaos
Hossenfelder: “… the chaotic motion of Hyperion tells us that we need the measurement collapse to actually be a physical process. Without it, quantum mechanics just doesn’t correctly describe our observations. But then what is this process? No one knows. And that’s the problem with quantum mechanics.”
