My Science & Epistemology Researches
A brief note on the dispersion of low-redshift measurements in the Pantheon+ database. This is part of my study of the alternative interpretation of redshift that does not involve the expansion of the universe.
The Pantheon+ database is one of the largest and most precise cosmological data collections in the world, consisting of 1,701 light curves from 1,550 Type Ia supernovae (SnIa).

“Free thoughts by Richard Feynman -highly relatable and easy to agree with- taken from a 1981 BBC interview. From the Italian version (Adelphi Edizioni) of his book The Pleasure of Finding Out.

A new video by Sabine Hossenfelder on simultaneity, well explained. Simultaneity is an aspect of our time that should be taken into greater consideration in all our theoretical developments in any field of knowledge. Instead, it is largely ignored.
This image of NGC 5335 was captured by the Hubble Space Telescope in 2025 to celebrate its 35th anniversary.

The galactic bulge is indeed an incredibly dense region. While the solar neighborhood has a stellar density of roughly about 1 star every 250 cubic light-years), the central bulge reaches densities of millions of stars per cubic light-year. In the densest parts, stars can be separated by only a few light-days or light-weeks, compared to the 4+ light-years between us and Proxima Centauri.

Looking at photographs of galaxies, one gets the impression that they are gas clouds, as they were actually considered before the resolution of optical instruments allowed us to identify individual sources. As in these splendid images from HST (the Hubble Space Telescope) and VISTA (the Visible and Infrared Survey Telescope for Astronomy, part of ESO’s Paranal Observatory).

A very thorough article with examples of the Feynman trick for integration (differentiation under the integral sign). But even in the simplest cases it is a precious tool.

After a hiatus from 2021, I’m resuming my online presence with this small collection of suggestions, seeking intellectual dialogue. Let me know what you think in the comments or via email.
Thanks
p.s. I posted with the dates of the original documents
