黑暗宇宙 The Dark Universe

2006年邵逸夫天文學獎頒發予索爾•普密特(Saul Perlmutter)、亞當•利斯(Adam Riess)、和布萊•施米茲(Brian Schmidt),以表彰他們發現宇宙正在加速膨脹的偉大發現。

宇宙學理論因為近年加速膨脹的發現,而重新改寫,天文學家知道宇宙間存在一種迷般的「黑暗能量」,以抗衡宇宙間的萬有引力,令宇宙不斷膨脹,還要是加速地膨脹,最終宇宙可能會面臨「大解體」的一天。我們眼所見的物質只佔宇宙間物質的4%,看不到但知道存在的「黑暗物質」也只佔全宇宙的22%,然而宇宙的 74%由不曉得的「黑暗能量」所充斥。

是次講座將為大家介紹本年的邵逸夫天文學獎內容,和近年宇宙學家對宇宙的認知。

The Shaw Prize in Astronomy 2006 is awarded jointly to Saul Perlmutter, Adam Riess and Brian Schmidt for discovering that the expansion rate of the universe is accelerating.

Cosmology is rewritten since the discovery of the accelerating universe. As we know, the universe consisted of mysterious "dark energy", counteract on the gravitational pull in the universe, and hence turning our universe into an accelerating expanding one. Maybe in the future, the universe will end in the "Big Rip". From our current understanding, the ordinary matter composed only 4% of the cosmos, while the unseen dark matter composed of 22%, but the unknown dark energy is composed of 74%.

In this lecture, this year Shaw Prize and the current understanding of the cosmos by cosmologists is discussed.
