QMU physics prof. Ginestra Bianconi proposes a new quantum gravity theory in which gravity is not a fundamental force but is “derived from an entropic action coupling matter fields with geometry”. The theory potentially explains dark matter (G-field) & dark energy (Λ).

Kudos to Kiwi Astronomers! Dark Energy? Maybe we don't need it! Having done work many years ago at NZ's U of Canterbury Mount John Observatory, I could not help but notice this article (see the report below for a link to the open-source journal article). www.msn.com/en-us/news/t...

Universe #acceleration seems well proved by measures of “Ia Supernovae,” but an accelerated Universe must have 95% Dark Energy and Dark Matter… and still today, we are not able to find particles of Dark Energy and Matter!!
Is the model correct?

👾💥DARK MATTER💥👾 What is it made of? Given the conflicting results (see chart, Physics 6, 136, Lang), is that even the right question? Somehow associated with matter, scientists know a little about what it isn't, but the mystery remains unsolved after many decades of research!

For some equally strange reason, I also remember the early version of the Goodnight TV Kiwi animation short that played at the end of each evening's transmission. 🤣
