The problem of local (e.g., interplanetary) Hubble expansion is studied for a long time but remains a controversial subject till now; and of particular interest is a plausible value of […]
![Observational data on the relative surface temperatures of the Earth and Mars Ts/Ts0 (upper left panel) vs. the theoretical predictions by a few cosmological models at various values of the Hubble parameter normalized to h = 100 km/s/Mpc (dotted curves in three other panels). Solid curves correspond to the standard intergalactic value of the Hubble parameter; and the long-dashed curves, to the original Kˇr´ıˇzek–Somer model [16, 21]. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/Estimating-The-Local-Hubble-Parameter.png?resize=1200%2C716&ssl=1)
