A very important issue has arisen this year as we receive new data from the one and only James Webb Space Telescope: Are the observations we’re getting back contradicting the current cosmological model of the universe?
Previews for this week’s article:
“Astronomers have used the James Webb and Hubble space telescopes to confirm one of the most troubling conundrums in all of physics — that the universe appears to be expanding at bafflingly different speeds depending on where we look.”
“Since it was launched in December 2021, the JWST has made its own measurements of Cepheid variables with its advanced infrared optics. This has allowed astronomers to cross-check the optical-light measurements made by Hubble [...]The team’s first look at Webb’s observations in 2023 confirmed that Hubble’s measurements of the expanding Universe were accurate.” (Matt Williams, Universe Today).
“Pointing the Webb telescope deep into the universe to try to confirm Hubble's complicated numbers back in 2023, scientists were puzzled when the newer telescope confirmed the findings of its predecessor, deepening the discrepancy [...] As Reiss speculates, there may be something greater going on than the numbers not adding up. ‘With measurement errors negated,’ he told NASA, ‘what remains is the real and exciting possibility we have misunderstood the universe’” (Noor Al-Sibai, Futurism).
