Equilibrium Energy Partition and Planck–Like Universality in Galactic Rotation Curves
[edit]This article presents a new approach for explaining galactic rotation curves without dark matter. The framework is based on equilibrium energy partition and suggests a universal Planck-like relation governing rotational dynamics.

- These days theories that explain galactic rotation curves without dark matter are dime a dozen. The new theory would need to explain something more (especially the cosmological evidence) for me to pay attention. Banedon (talk) 08:51, 12 March 2026 (UTC)
Did Voyager 1 really measure Hawking radiation? Is that a prank?
[edit]Someone knowledgeable please verify this statement, in the first sentence of 4th paragraph of section "Primordial black holes"
On 5-May and 10-May-2026, it reads:
"Various observational constraints, such as gravitational microlensing data from the Subaru Telescope (HSC) and Voyager 1 measurements of Hawking radiation, have ruled out PBHs constituting 100% of dark matter in specific mass windows (e.g., evaporating tiny black holes or monochromatic intermediate-mass populations).[162]"
The second part of that sentence feels like a prank. [162] corroborates the Subaru Telescope part, but nothing corroborates the "Voyager 1 measurements of Hawking radiation" part. Neither the linked "Voyager 1" nor the "Hawking radiation" article state this, either. The latter makes it quite unlikely that Voyager 1 could measure it.

- Pretty sure you are right. Too bad it's not so. Interesting times for resolving the Hubble "constant" dilemma. Pete Tillman (talk) 19:38, 10 May 2026 (UTC)
- Thank you. I found a reference for Voyager 1 data being used to constrain the amount of tiny PBHs, and added it as reference. Karl Missouri (talk) 14:06, 11 May 2026 (UTC)
