76. 韦布望远镜测定哈勃常数
from 知为谁 · host 知为谁
借助新的詹姆斯·韦伯太空望远镜，科学家们正在重新计算宇宙的膨胀速度，即哈勃常数。 过去十年来，对早期宇宙（通过宇宙微波背景测量）和当前宇宙（通过测量恒星和超新星的距离和速度）的测量似乎存在分歧，这给标准宇宙模型带来了问题。然而，新的数据，特别是韦伯望远镜更高分辨率和灵敏度的测量，通过更精确地确定距离，使得计算值与早期宇宙的测量结果更接近。这一发现强烈支持了我们目前的宇宙标准模型，表明之前看似的矛盾可能并不存在，尽管科学家们仍在继续探索可能挑战该模型的其他现象。内容来源：https://phys.org/news/2025-05-webb-telescope-refines-hubble-constant.html
