Hubble Tension Drama Continues: JWST Data In A Tug-Of-War Between The Two Camps

Is our model of the universe broken? JWST data says maybe, but also maybe not.

Webb telescope helps refines Hubble constant, suggesting resolution to long-standing expansion rate debate

For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the universe. The universe expands over time, but how fast it's expanding has seemed to differ depending on whether you looked early in the universe's history or the present day. If true, this would have presented a major problem to the gold-standard model that represents our best understanding of the universe.

CMB: Big Bang's Echo or Ancient Galaxies' Glow? A Cosmic Rethink!

Hello, fellow space explorers, and welcome back to FreeAstroScience.com! Today, we're diving into a topic that could shake the very foundations of our understanding of the universe's beginnings. For decades, we've looked to the Cosmic Microwave Background (CMB) as the definitive "first light" after the Big Bang. But what if there's more to the story? What if a significant part of this ancient glow isn't what we've always thought? We invite you, …

Astronomers solved a long-standing mystery.

Astronomers have used the Webb Space Telescope to better understand the rate at which the universe is expanding, known as the Hubble constant. They have discovered that the difference in the expansion rate may not exist after all. The article Hubble Constant: How Fast Is the Universe Expanding? is from the website Everything That Matters.

Observations with the James Webb space telescope suggest that there would be no conflict between the standard model of physics for the Universe and its rate of expansion, known as the Hubble constant.
