天文学家测量宇宙膨胀速度为73.50公里/秒/英里半秒, 显示与早期预测的差异. Astronomers measured the universe's expansion rate at 73.50 km/s/Mpc, revealing a discrepancy with earlier predictions.

太空学家已经比以往更精确地测量了宇宙膨胀速度,发现它是73.50公里/秒/Mpc. Astronomers have measured the universe's expansion rate with greater precision than ever, finding it to be 73.50 km/s/Mpc. 这种局部测量与早期预测相冲突, 造成一种被称为"哈勃张力"的持续差异. This local measurement conflicts with earlier predictions, creating a persistent discrepancy known as the "Hubble tension." 这项研究表明这种不匹配可能会揭示标准模型之外的新物理. The study suggests this mismatch may reveal new physics beyond the standard model.
