Deep space observations of the JWST have revealed that the structure and masses of very early Universe galaxies at high redshifts (z ∼ 15), existing at ∼0.3 Gyr after the Big Bang, may be as evolved as the galaxies in existence for ∼ 10 Gyr. The JWST findings are thus in strong tension with the CDM cosmological model. While tired light ...

2025年3月11日 · Abstract: The James Webb Space Telescope (JWST) has observed massive galaxies at high redshifts, which implies an earlier epoch of reionization (EoR) compared with the cosmic microwave background (CMB) results. In this paper, based on \texttt{Planck 2020} (NPIPE release), \texttt{ACT DR4} and \texttt{SPT-3G} data, if assumed a Harrison-Zel ...

2023年7月7日 · While tired light (TL) models have been shown to comply with the JWST angular galaxy size data, they cannot satisfactorily explain isotropy of the cosmic microwave background (CMB) observations or fit the supernovae distance modulus versus redshift data well.

2023年9月22日 · Deep space observations of the James Webb Space Telescope (JWST) have revealed that the structure and masses of very early Universe galaxies at high redshifts (z~15), existing at ~0.3 Gyr after the BigBang, maybe as evolved as the galaxies in existence for ~10 Gyr. The JWST findings are thus in strong tension with the Λ CDM cosmological model.

2023年7月1日 · While tired light (TL) models comply with the JWST data, they cannot adequately explain isotropy of the cosmic microwave background (CMB) observations or fit the supernovae distance modulus vs. redshift data well. We have developed hybrid models that include the tired light concept in the expanding universe.

While tired light (TL) models have been shown to comply with the JWST angular galaxy size data, they cannot satisfactorily explain isotropy of the cosmic microwave background (CMB) observations or fit the supernovae distance modulus versus redshift data well.

With its 6.5m diameter primary mirror and four science instruments, JWST operates at near- and mid-infrared wavelengths. Its unprecedented sensitivity and resolution at these wavelengths allows it to address science questions both near and far: from characterising planets and stellar nurseries nearby to searching for the first galaxies to ...

2024年3月28日 · 使用标准宇宙学模型拟合宇宙微波背景辐射（cosmic microwave background，CMB）数据，就可以得到哈勃常数与其他重要的宇宙学参数。 理论表明，CMB形成于宇宙大爆炸后约38万年，当时宇宙中的电子与氢离子（质子）复合为中性的氢原子，基本不再与 …

2024年3月14日 · In 2019, measurements by the Hubble Space Telescope confirmed the puzzle was real; in 2023, even more precise measurements from the James Webb Space Telescope (JWST) cemented the discrepancy....
