這題答案為什麼是A

B (A)靜止不動 (B)向我們接近 (C)離我們遠去(D)無常規 (S) 2.哈伯定律認為星系奔離速度與星系距離成正比。我們以往認為宇宙年齡約為138億 年,是基於普朗克衛星利用宇宙微波背景輻射,測得哈伯常數值約為68km/s/Mpc 所下的推論。然而,近來科學家使用哈伯太空望遠鏡觀測 70 顆造父變星,卻得出哈 伯常數值為74 km/s/Mpc,若依此觀測結果做推論,則宇宙膨脹速度及年齡相較於以 v=Ho 往會有何不同? (A)膨脹速度應更快,宇宙年齡應更年輕 (B)膨脹速度應更快,宇宙年齡應更年老 (C)膨脹速度應更快,但宇宙年齡不變 (D)膨脹速度應更慢,宇宙年齡應更年輕 (E)膨脹速度應更慢,宇宙年齡應更年老。 个个 達到目前星系相对 距離所需 tine短,宇宙演化 經歷短
