Measure the Universe with Cosmological Standard Timers
Since the first humans were born on Earth, we have been trying to learn about the Universe in which we inhibit. Thousands of years of observations and thinking have enabled us to develop a standard cosmological model capable of better describing the evolution of the Universe since the hot big bang. With technical progress and the development of precise measurement techniques, more results show that there is inconsistency between observation and theory, such as Hubble tension, which poses a pressing problem in modern cosmology…..

使用宇宙標準計時器測量宇宙
自人類於地球誕生，我們一直嘗試了解我們所在的宇宙。經過了數千載的觀察和思考，我們已經發展了一套宇宙學標準模型，可讓我們更好地描述宇宙熱大爆炸以來的演化。然而，隨著科技進步和精確測量技術的發展，更多結果顯示觀測和理論之間存在著矛盾，其中哈勃常數疑難，便是現代宇宙學中的一個迫在眉睫、亟待解決的問題…..
