‎NETFLIX 紀錄片系列

2
00:00:25,363 --> 00:00:27,963
‎地球上每個生物的生命

3
00:00:31,403 --> 00:00:32,283
‎都映照出

4
00:00:35,163 --> 00:00:38,923
‎千古以前所發生的事件

5
00:00:43,643 --> 00:00:45,643
‎那些規模難以想像的事件

6
00:00:47,963 --> 00:00:49,323
‎具衝擊性的美感

7
00:00:51,483 --> 00:00:54,283
‎與所有生物產生連結

8
00:00:56,123 --> 00:00:58,803
‎包括牠們每一個行動與決定

9
00:00:59,483 --> 00:01:00,843
‎牠們每一個心跳

10
00:01:02,443 --> 00:01:05,763
‎交織成史上最壯闊的篇章

11
00:01:07,803 --> 00:01:12,443
‎這個故事耗費了138億年寫就

12
00:01:14,723 --> 00:01:17,203
‎見證數十億顆星子

13
00:01:18,283 --> 00:01:20,083
‎與數十億個世界

14
00:01:22,283 --> 00:01:25,483
‎生生死死

15
00:01:27,963 --> 00:01:30,563
‎才創造出目前已知的唯一星球

16
00:01:32,243 --> 00:01:34,923
‎能成為生命的家園

17
00:01:39,243 --> 00:01:41,203
‎從塑造萬物的星塵…

18
00:01:43,483 --> 00:01:46,683
‎到維繫萬物生命的宇宙成分…

19
00:01:52,923 --> 00:01:56,443
‎再到供給萬物能量的星光

20
00:01:58,003 --> 00:02:03,403
‎這就是我們浩瀚宇宙的故事

21
00:02:28,043 --> 00:02:32,523
‎劇名：追逐星光

22
00:02:39,603 --> 00:02:40,843
‎東非

23
00:02:42,003 --> 00:02:45,843
‎（坦尚尼亞塞倫蓋提）

24
00:02:46,203 --> 00:02:50,923
‎在這裡可以找到
‎生命與宇宙至關重要的連結

25
00:02:55,043 --> 00:02:57,323
‎還能找到一隻特別的掠食動物

26
00:03:00,443 --> 00:03:02,683
‎牠叫瓦契尼

27
00:03:06,043 --> 00:03:10,203
‎獵豹終其一生都在不斷覓食

28
00:03:12,363 --> 00:03:13,723
‎以補充生命能量

29
00:03:16,163 --> 00:03:21,443
‎這裡可說是地球上
‎掠食動物最難找到獵物的地方

30
00:03:31,043 --> 00:03:34,283
‎炙熱的烈陽幾乎逼走了所有動物

31
00:03:34,363 --> 00:03:36,643
‎只剩這片乾燥的荒原

32
00:03:42,843 --> 00:03:46,883
‎留下來的生物都奮力掙扎求生

33
00:03:51,523 --> 00:03:53,643
‎瓦契尼全神貫注

34
00:03:57,403 --> 00:03:59,603
‎唯一能驅使牠前進的動力

35
00:04:03,043 --> 00:04:04,123
‎是飢餓感

36
00:04:07,843 --> 00:04:10,843
‎這樣單純的原始衝動

37
00:04:10,923 --> 00:04:14,603
‎源自牠跟周圍環境的深厚連結

38
00:04:15,563 --> 00:04:18,723
‎這個連結延伸到塞倫蓋提之外

39
00:04:19,323 --> 00:04:20,883
‎超越我們的星球

40
00:04:22,043 --> 00:04:23,683
‎來到宇宙本身

41
00:04:29,763 --> 00:04:31,843
‎瓦契尼體內的每一個細胞

42
00:04:34,203 --> 00:04:36,843
‎都與遠古的能量流相連

43
00:04:39,963 --> 00:04:44,283
‎將牠的生命與恆星的心臟緊緊相扣

44
00:04:49,883 --> 00:04:53,683
‎這股源源不斷的能量流
‎穿越過廣闊的太空

45
00:04:58,283 --> 00:05:02,203
‎並追溯至138億年前

46
00:05:13,243 --> 00:05:18,323
‎打從我們宇宙起源便存在的遠古能量

47
00:05:20,163 --> 00:05:21,403
‎驅動著一切

48
00:05:23,243 --> 00:05:24,523
‎每顆行星

49
00:05:26,363 --> 00:05:27,323
‎每顆恆星

50
00:05:30,523 --> 00:05:31,443
‎每條生命

51
00:05:40,243 --> 00:05:42,723
‎瓦契尼正在尋找能量

52
00:05:46,123 --> 00:05:47,683
‎但不只為了牠自己

53
00:05:49,483 --> 00:05:52,083
‎身為兩隻五個月大的幼豹的媽

54
00:05:53,843 --> 00:05:56,923
‎牠急需餵飽這飢餓的一家三口

55
00:06:04,443 --> 00:06:06,203
‎現在是乾季

56
00:06:06,283 --> 00:06:07,643
‎食物正匱乏

57
00:06:08,963 --> 00:06:12,043
‎然而，此時的能量卻比以往豐沛

58
00:06:15,963 --> 00:06:17,923
‎只是隱藏在光天化日下

59
00:06:21,323 --> 00:06:25,723
‎太陽系中最大、最亮、最熱的天體

60
00:06:28,283 --> 00:06:29,443
‎太陽

61
00:06:41,283 --> 00:06:45,643
‎巨大熾熱的電漿環自表面噴發

62
00:06:52,003 --> 00:06:55,123
‎太陽每秒所釋放出的能量

63
00:06:55,203 --> 00:06:58,763
‎相當於4.5兆顆原子彈

64
00:07:01,603 --> 00:07:04,323
‎一小時內輸送到地球的能源

65
00:07:04,923 --> 00:07:08,003
‎比全球一年的消耗量還多

66
00:07:12,563 --> 00:07:16,283
‎但儘管這顆巨大火球能量驚人

67
00:07:18,723 --> 00:07:21,563
‎瓦契尼吃不到日光

68
00:07:23,803 --> 00:07:26,363
‎牠只吃會跑的生物

69
00:07:29,323 --> 00:07:30,563
‎比方說瞪羚

70
00:07:38,803 --> 00:07:41,563
‎牠的斑點毛皮為牠提供了偽裝

71
00:07:42,523 --> 00:07:44,803
‎是尾隨獵物時的必備能力

72
00:07:58,243 --> 00:07:59,883
‎這裡幾乎無處可藏

73
00:08:01,243 --> 00:08:03,683
‎貿然靠近獵物並非上策

74
00:08:15,683 --> 00:08:18,963
‎所幸，瓦契尼身懷絕技

75
00:08:26,323 --> 00:08:29,843
‎獵豹是陸地上跑最快的動物

76
00:08:32,203 --> 00:08:35,523
‎從零加速到時速一百公里只需三秒

77
00:08:37,483 --> 00:08:40,843
‎但瞪羚也不遑多讓

78
00:08:45,123 --> 00:08:47,323
‎瓦契尼耗費大量體力

79
00:09:00,003 --> 00:09:01,323
‎結果一無所獲

80
00:09:05,443 --> 00:09:08,923
‎一隻成年獵豹可以超過一週不吃東西

81
00:09:12,643 --> 00:09:17,163
‎但幼豹頂多只能幾天不進食

82
00:09:24,123 --> 00:09:29,483
‎而這兩隻已經飢餓難耐

83
00:09:31,763 --> 00:09:36,283
‎（上一餐，24小時前）

84
00:09:37,883 --> 00:09:40,963
‎用這麼高的跑速狩獵非常消耗

85
00:09:43,243 --> 00:09:46,523
‎瓦契尼的體力如今所剩無幾

86
00:09:50,723 --> 00:09:54,243
‎牠得歇個數小時才會有力氣再次狩獵

87
00:10:00,243 --> 00:10:04,043
‎瓦契尼和牠的寶寶只能繼續餓肚子

88
00:10:22,083 --> 00:10:25,443
‎世界各地的動物都在打同樣的仗

89
00:10:26,523 --> 00:10:27,803
‎在攝取能量…

90
00:10:31,363 --> 00:10:32,843
‎與使用能量間奮戰

91
00:10:38,203 --> 00:10:40,043
‎無論使用什麼策略

92
00:10:40,123 --> 00:10:42,003
‎快攻還是慢守

93
00:10:47,123 --> 00:10:50,043
‎都無法保證有下一餐

94
00:10:59,323 --> 00:11:03,443
‎飢餓是萬物都必須克服的問題

95
00:11:04,843 --> 00:11:08,683
‎（上一餐，30小時前）

96
00:11:12,643 --> 00:11:14,963
‎自上次追逐戰恢復體力後

97
00:11:15,963 --> 00:11:18,563
‎瓦契尼開始尋找下一個機會

98
00:11:22,963 --> 00:11:24,443
‎跟所有獵豹媽媽一樣

99
00:11:26,083 --> 00:11:27,963
‎牠是單親家庭

100
00:11:31,203 --> 00:11:33,643
‎要餵飽兩隻幼豹

101
00:11:34,363 --> 00:11:36,603
‎牠每天都得抓一隻獵物回家

102
00:11:38,283 --> 00:11:40,963
‎但恢復體力花了牠不少時間

103
00:11:42,283 --> 00:11:44,123
‎現在太陽都要下山了

104
00:11:53,763 --> 00:11:55,323
‎光線漸漸消逝

105
00:11:56,523 --> 00:11:58,923
‎牠們飽餐一頓的希望也跟著黯淡

106
00:12:05,923 --> 00:12:07,403
‎隨著地球自轉

107
00:12:10,003 --> 00:12:12,443
‎塞倫蓋提轉向沒有太陽的那側

108
00:12:13,883 --> 00:12:15,243
‎進入黑夜

109
00:12:21,563 --> 00:12:24,963
‎這大力提醒我們
‎生命與太陽的關係密不可分

110
00:12:29,243 --> 00:12:32,883
‎我們的故事就是太陽的故事

111
00:12:35,203 --> 00:12:36,603
‎很久很久以前

112
00:12:39,803 --> 00:12:44,483
‎我們的太陽系比今日更加寒冷陰暗

113
00:12:52,723 --> 00:12:56,843
‎（46億年前）

114
00:12:56,923 --> 00:13:02,003
‎然而，這是恆星誕生的完美條件

115
00:13:05,243 --> 00:13:07,803
‎在接近絕對零度的溫度下

116
00:13:08,683 --> 00:13:12,003
‎重力開始吸引塵埃和氣體

117
00:13:14,283 --> 00:13:15,803
‎凝聚成巨大星雲

118
00:13:22,923 --> 00:13:24,763
‎星雲向內塌陷

119
00:13:24,843 --> 00:13:28,283
‎擠壓成一球燒得火紅的氣團

120
00:13:32,283 --> 00:13:33,643
‎名為原恆星

121
00:13:40,923 --> 00:13:42,243
‎如同瓦契尼

122
00:13:42,323 --> 00:13:45,203
‎這顆成形中的恆星有著強烈的飢餓感

123
00:13:48,043 --> 00:13:49,603
‎它吸入太多氣體

124
00:13:49,683 --> 00:13:51,363
‎以至一股股熾熱的物質

125
00:13:52,323 --> 00:13:54,803
‎從兩極噴射出去

126
00:13:56,323 --> 00:13:59,003
‎射到好幾光年之外的太空

127
00:14:02,323 --> 00:14:08,363
‎這顆嬰兒恆星持續成長了三千萬年

128
00:14:19,483 --> 00:14:20,723
‎直到最後

129
00:14:21,923 --> 00:14:26,243
‎它熱到足以靠自身生產能量

130
00:14:29,403 --> 00:14:30,363
‎形成我們的太陽

131
00:14:33,323 --> 00:14:37,203
‎太陽的金色光芒至今璀璨而穩定

132
00:14:39,243 --> 00:14:41,683
‎照耀了46億年

133
00:14:47,443 --> 00:14:52,003
‎它在這個銀河系內
‎不過是數十億顆星中的一顆

134
00:14:57,403 --> 00:15:00,803
‎然而，它是最特別的一顆

135
00:15:03,163 --> 00:15:06,123
‎因為它將光與熱輸送到…

136
00:15:08,483 --> 00:15:11,283
‎這顆不可思議、生機蓬勃的星球

137
00:15:16,043 --> 00:15:20,963
‎（上一餐，42小時前）

138
00:15:23,723 --> 00:15:25,443
‎塞倫蓋提的每一個生物

139
00:15:25,523 --> 00:15:27,803
‎都仰賴太陽來提供能量

140
00:15:29,843 --> 00:15:34,123
‎瓦契尼的寶寶已經餓到筋疲力盡了

141
00:15:35,203 --> 00:15:37,323
‎牠們今天必須吃東西

142
00:15:39,043 --> 00:15:41,683
‎可是瓦契尼今天早上能提供的

143
00:15:42,443 --> 00:15:44,203
‎只有溫柔與關愛

144
00:15:45,843 --> 00:15:47,563
‎在這片乾枯之地

145
00:15:48,083 --> 00:15:52,483
‎我們的太陽既慷慨又殘酷

146
00:15:53,683 --> 00:15:57,163
‎它強烈的能量是生命所需

147
00:15:58,363 --> 00:16:02,323
‎但它同時也具有毀滅能力

148
00:16:06,643 --> 00:16:12,363
‎與這座巨大的核反應爐比鄰而居
‎從來不是件容易的事

149
00:16:21,323 --> 00:16:24,203
‎想了解這股難以承受之熱的源頭

150
00:16:25,403 --> 00:16:28,083
‎我們就必須深入煉獄…

151
00:16:37,283 --> 00:16:40,283
‎潛進沸騰的熱電漿外層

152
00:16:46,003 --> 00:16:50,163
‎下探65萬公里

153
00:16:54,963 --> 00:16:57,163
‎來到太陽的核心

154
00:17:00,883 --> 00:17:04,883
‎我們的恆星心臟看起來出奇的平靜

155
00:17:07,083 --> 00:17:10,923
‎但在原子層面，實則一片混沌

156
00:17:14,403 --> 00:17:18,323
‎這是我們太陽系中最炙熱的部分

157
00:17:21,043 --> 00:17:24,483
‎這裡的溫度高達攝氏1500萬度

158
00:17:27,683 --> 00:17:32,243
‎為一個事件的發生
‎創造出幾乎絕無僅有的絕佳環境

159
00:17:36,643 --> 00:17:39,603
‎原子在此高速碰撞並融合

160
00:17:45,203 --> 00:17:47,043
‎釋放出純粹的能量

161
00:17:54,803 --> 00:17:59,083
‎這個過程叫做核融合

162
00:17:59,923 --> 00:18:02,363
‎讓太陽得以發光

163
00:18:06,523 --> 00:18:11,163
‎事實上，核融合是
‎宇宙中所有恆星的動力來源

164
00:18:15,243 --> 00:18:20,363
‎恆星釋放的能量可以追溯到時間伊始

165
00:18:25,523 --> 00:18:27,803
‎那時並沒有物質

166
00:18:27,883 --> 00:18:32,123
‎整個宇宙只存在著能量

167
00:18:35,163 --> 00:18:39,043
‎那一點一滴的能量
‎至今仍存在於我們的宇宙中

168
00:18:46,643 --> 00:18:48,483
‎當陽光照射在塞倫蓋提

169
00:18:49,923 --> 00:18:53,323
‎流淌了138億年的能量

170
00:18:54,923 --> 00:18:58,283
‎便來到瓦契尼和牠的孩子面前

171
00:18:59,083 --> 00:19:03,283
‎並繼續在牠們的環境中流轉

172
00:19:04,923 --> 00:19:08,123
‎能量永遠不會被創造或毀滅

173
00:19:09,043 --> 00:19:12,883
‎只會無止盡地轉化

174
00:19:13,763 --> 00:19:18,883
‎但瓦契尼和牠的孩子
‎只能從一種形態獲得這股能量

175
00:19:23,603 --> 00:19:24,603
‎肉

176
00:19:33,843 --> 00:19:36,443
‎外頭存在著敵對的掠食動物

177
00:19:39,243 --> 00:19:42,163
‎不僅會劫走牠的食物

178
00:19:42,243 --> 00:19:43,523
‎還會劫走牠的寶寶

179
00:19:58,123 --> 00:20:00,003
‎牠們再不快點進食

180
00:20:01,043 --> 00:20:02,523
‎死亡不過是遲早的事

181
00:20:23,523 --> 00:20:26,603
‎這只夠塞牙縫，但兩天沒東西吃

182
00:20:27,123 --> 00:20:28,523
‎它便是救命稻草

183
00:20:32,523 --> 00:20:35,883
‎但獵豹的獵物，超過10%都會被偷走

184
00:20:40,323 --> 00:20:43,963
‎瓦契尼必須守住
‎牠捕獲的每一丁點能量

185
00:20:47,883 --> 00:20:49,923
‎因為當能量匱乏

186
00:20:50,763 --> 00:20:53,243
‎競爭越發激烈

187
00:20:57,123 --> 00:21:01,363
‎瓦契尼一再為了生存養家而打拚

188
00:21:01,443 --> 00:21:03,483
‎日復一日

189
00:21:06,083 --> 00:21:07,883
‎月復一月

190
00:21:17,923 --> 00:21:21,563
‎每頓餐都是一場仗

191
00:21:27,363 --> 00:21:30,483
‎在使用和獲取能量的戰役中

192
00:21:32,603 --> 00:21:35,123
‎瓦契尼只能勉強打平

193
00:21:40,443 --> 00:21:43,203
‎在塞倫蓋提的乾季

194
00:21:43,283 --> 00:21:45,643
‎挨餓是家常便飯

195
00:21:52,083 --> 00:21:53,803
‎但天色即將改變

196
00:21:55,603 --> 00:22:00,723
‎太陽的熱能將濕氣高高吸入空中

197
00:22:05,123 --> 00:22:06,603
‎東西一旦上升

198
00:22:07,923 --> 00:22:11,163
‎最終勢必會降落

199
00:22:14,723 --> 00:22:17,483
‎大雨橫掃平原

200
00:22:18,403 --> 00:22:20,923
‎劃下了乾季的句點

201
00:22:26,683 --> 00:22:28,323
‎烏雲漸漸散去

202
00:22:30,003 --> 00:22:31,803
‎一線希望隨之出現

203
00:22:44,163 --> 00:22:47,443
‎一株草無法養活瓦契尼一家子

204
00:22:49,963 --> 00:22:54,523
‎但在它的細胞深處
‎藏有為牠們止飢的答案

205
00:23:06,563 --> 00:23:09,123
‎這裡有個隱密的小天地

206
00:23:15,043 --> 00:23:18,763
‎層層堆疊的微小囊體，稱作葉綠餅

207
00:23:18,843 --> 00:23:21,643
‎沐浴在溫暖的陽光中

208
00:23:32,843 --> 00:23:37,643
‎葉綠餅表面佈滿了
‎森林般的小小捕光蛋白

209
00:23:38,923 --> 00:23:42,763
‎能從離我們最近的恆星那兒攫取能量

210
00:23:47,843 --> 00:23:50,763
‎它們富含綠色的葉綠素

211
00:23:52,443 --> 00:23:55,083
‎能吸收光線

212
00:24:00,043 --> 00:24:02,283
‎透過神奇的光合作用

213
00:24:12,683 --> 00:24:15,243
‎水與二氧化碳結合

214
00:24:18,363 --> 00:24:21,403
‎將陽光轉化為糖分

215
00:24:38,483 --> 00:24:41,323
‎不出幾天，曾經乾枯的平原

216
00:24:41,403 --> 00:24:43,203
‎便添上了綠意

217
00:24:51,523 --> 00:24:55,483
‎如今數十億株青草吸收滿滿的陽光

218
00:25:00,523 --> 00:25:05,003
‎宇宙的能量也就此鑲進了地景

219
00:25:10,443 --> 00:25:11,963
‎只剩一個問題

220
00:25:14,523 --> 00:25:17,043
‎獵豹不吃草

221
00:25:22,963 --> 00:25:25,843
‎不過在遙遠的北方林地中

222
00:25:27,123 --> 00:25:31,123
‎有野獸以草為食

223
00:25:34,123 --> 00:25:36,123
‎數量多達幾十萬隻

224
00:25:38,923 --> 00:25:40,163
‎牛羚

225
00:25:43,163 --> 00:25:46,763
‎牠們有寬大的嘴、靈活的嘴唇

226
00:25:46,843 --> 00:25:48,363
‎還有四個胃

227
00:25:49,083 --> 00:25:51,963
‎器官完全演化用來吃草

228
00:26:01,123 --> 00:26:03,923
‎這一大群牛羚時常遷徙

229
00:26:05,843 --> 00:26:07,683
‎尋找新鮮的牧地

230
00:26:11,043 --> 00:26:14,123
‎為了找到青草，牠們跟著雨走

231
00:26:17,843 --> 00:26:19,243
‎如同我們一樣

232
00:26:21,283 --> 00:26:22,363
‎受飢餓感驅使

233
00:26:32,043 --> 00:26:34,563
‎但若塞倫蓋提有一條法則

234
00:26:36,243 --> 00:26:39,123
‎那就是食物得來不易

235
00:26:48,043 --> 00:26:49,523
‎馬拉河

236
00:26:52,163 --> 00:26:55,203
‎棲息著地球上最巨大的鱷魚

237
00:26:59,123 --> 00:27:00,883
‎嚴重阻礙了

238
00:27:00,963 --> 00:27:04,123
‎牛羚尋找生命能量的旅途

239
00:27:16,203 --> 00:27:17,683
‎在南方

240
00:27:17,763 --> 00:27:22,443
‎瓦契尼用盡每時每刻
‎探查平原，尋找吃的東西

241
00:27:33,043 --> 00:27:36,043
‎經歷六個月的三餐不繼後

242
00:27:37,723 --> 00:27:40,203
‎牠的一個孩子好不容易長大了

243
00:27:47,763 --> 00:27:50,803
‎甚至還學會了自己的狩獵技巧

244
00:27:57,043 --> 00:28:01,243
‎但另一個孩子不見蹤影

245
00:28:07,443 --> 00:28:10,843
‎只有5%的獵豹寶寶能成功進入成年

246
00:28:13,723 --> 00:28:17,643
‎大部分幼豹都死在
‎飢餓的獅子和鬣狗手上

247
00:28:25,243 --> 00:28:28,923
‎這隻幼豹的未來仍算不上有保障

248
00:28:32,923 --> 00:28:36,043
‎即使能量就近在咫尺

249
00:28:42,443 --> 00:28:44,403
‎牛羚聚集在馬拉河岸

250
00:28:45,283 --> 00:28:48,203
‎牠們除了向前，無處可去

251
00:28:52,123 --> 00:28:55,203
‎但總得有人邁出第一步

252
00:29:34,923 --> 00:29:37,123
‎每年有150萬隻牛羚

253
00:29:38,083 --> 00:29:40,603
‎踏上這段旅程

254
00:29:44,323 --> 00:29:48,603
‎在這裡，使用與攝取能量的戰役

255
00:29:50,723 --> 00:29:52,723
‎以史詩級的規模展開

256
00:30:08,163 --> 00:30:10,883
‎對幸運過河的牛羚來說

257
00:30:12,443 --> 00:30:14,043
‎這只是開始

258
00:30:23,243 --> 00:30:25,923
‎接下來牠們必須行過數百公里

259
00:30:27,843 --> 00:30:28,843
‎不分晝夜

260
00:30:30,083 --> 00:30:31,363
‎歷時兩個多月

261
00:30:34,243 --> 00:30:35,923
‎才能抵達草原

262
00:30:48,643 --> 00:30:52,443
‎瓦契尼虎視眈眈，等待牛羚到來

263
00:30:53,963 --> 00:30:56,923
‎但有另一場遷徙正在發生

264
00:30:57,003 --> 00:31:00,643
‎攸關這兩種動物的存亡

265
00:31:03,883 --> 00:31:08,403
‎這個旅程的路途與時間都難以丈量

266
00:31:11,683 --> 00:31:13,123
‎沒有它

267
00:31:13,203 --> 00:31:17,043
‎塞倫蓋提的每個生物都會挨餓

268
00:31:24,243 --> 00:31:26,243
‎在太陽的核心

269
00:31:26,323 --> 00:31:28,603
‎原子碰撞並融合之際

270
00:31:29,403 --> 00:31:34,403
‎光子被釋放出來，向外流竄

271
00:31:38,843 --> 00:31:41,443
‎光子是裝著光能的小包裹

272
00:31:42,243 --> 00:31:44,043
‎質量為零

273
00:31:44,123 --> 00:31:46,123
‎並以光速傳播

274
00:31:47,843 --> 00:31:51,123
‎但在密度極高的核心內

275
00:31:51,203 --> 00:31:55,123
‎光子遭到限制、吸收、分散

276
00:31:58,243 --> 00:32:01,083
‎本來只需要兩秒的旅程

277
00:32:02,123 --> 00:32:03,843
‎可能得花上一百萬年

278
00:32:11,003 --> 00:32:15,123
‎逃離太陽沒想到會如此折騰

279
00:32:20,043 --> 00:32:23,443
‎但慢慢地，光子往上竄升

280
00:32:25,243 --> 00:32:27,723
‎穿過太陽的層層關卡

281
00:32:29,683 --> 00:32:31,923
‎朝炎熱的表面前進

282
00:32:34,523 --> 00:32:37,243
‎它們終將在此獲得釋放

283
00:32:40,723 --> 00:32:43,403
‎光子向四面八方輻射出去

284
00:32:45,683 --> 00:32:46,923
‎形成星光

285
00:32:53,763 --> 00:32:59,603
‎短短八分多鐘飛越一億五千萬公里

286
00:33:04,923 --> 00:33:06,683
‎及時抵達目的地

287
00:33:09,203 --> 00:33:12,763
‎在旅途的尾端和牛羚群碰面

288
00:33:16,443 --> 00:33:22,843
‎每一片青草每秒能吸收一萬兆個光子

289
00:33:27,923 --> 00:33:33,523
‎攫取的能量足以養活龐大的牛羚群

290
00:33:43,763 --> 00:33:44,643
‎從恆星

291
00:33:47,643 --> 00:33:48,603
‎到青草

292
00:33:52,323 --> 00:33:53,323
‎再到牛羚

293
00:33:59,763 --> 00:34:02,603
‎陽光供給的能量讓牠們能夠移動

294
00:34:04,683 --> 00:34:05,523
‎成長

295
00:34:07,803 --> 00:34:08,923
‎繁殖

296
00:34:17,203 --> 00:34:20,243
‎牠們在草原上吃草的時間越久

297
00:34:21,083 --> 00:34:24,163
‎牠們就越有可能被吃掉

298
00:34:39,923 --> 00:34:45,163
‎豐富、美味、充足的能量

299
00:34:45,243 --> 00:34:47,643
‎終於觸手可及

300
00:34:55,843 --> 00:34:58,203
‎但三百萬隻眼睛的注視下

301
00:35:01,843 --> 00:35:03,923
‎瓦契尼必須速戰速決

302
00:35:06,603 --> 00:35:09,363
‎所幸，牠是一頭獵豹

303
00:35:59,283 --> 00:36:03,123
‎終於，瓦契尼嚐到了星光的滋味

304
00:36:26,083 --> 00:36:27,523
‎每咬一口

305
00:36:27,603 --> 00:36:31,723
‎蛋白質和脂肪中滿滿的宇宙能量

306
00:36:31,803 --> 00:36:33,723
‎便進入瓦契尼的血液裡

307
00:36:39,883 --> 00:36:41,723
‎它們的最終目的地

308
00:36:41,803 --> 00:36:44,403
‎是牠體內的細胞發電廠

309
00:36:45,563 --> 00:36:46,763
‎線粒體

310
00:36:49,123 --> 00:36:52,763
‎能量的最後一次轉化將在此發生

311
00:37:00,883 --> 00:37:04,683
‎每個線粒體內都是一片波濤洶湧

312
00:37:08,763 --> 00:37:13,043
‎峽谷般的內膜中
‎汩汩流著複雜的化合物

313
00:37:15,123 --> 00:37:19,403
‎在此，富含能量的食物與氧氣反應

314
00:37:20,203 --> 00:37:21,963
‎最後分解

315
00:37:28,723 --> 00:37:34,003
‎將宇宙的能量
‎直接送進瓦契尼的細胞中

316
00:37:38,483 --> 00:37:41,203
‎驅動每一個行動和思考

317
00:37:41,963 --> 00:37:43,683
‎每一個小動作

318
00:37:51,203 --> 00:37:54,043
‎從恆星到細胞的旅程至此完結

319
00:37:59,043 --> 00:38:01,203
‎曾經照亮宇宙的能量

320
00:38:02,603 --> 00:38:06,003
‎如今為瓦契尼和孩子獻上生命的贈禮

321
00:38:18,963 --> 00:38:20,243
‎在綠色季節裡

322
00:38:21,203 --> 00:38:22,923
‎飢餓只成追憶

323
00:38:32,923 --> 00:38:36,963
‎在塞倫蓋提平原上
‎能量不斷經歷轉化

324
00:38:41,363 --> 00:38:44,003
‎從一個生命傳到另一個生命

325
00:38:45,683 --> 00:38:48,523
‎滋養著整個生態系

326
00:38:51,443 --> 00:38:54,363
‎我們的太陽是最終供應者

327
00:38:55,643 --> 00:38:58,203
‎萬物都以星光為食

328
00:39:03,723 --> 00:39:07,363
‎問題是，沒有東西能餵養太陽

329
00:39:10,963 --> 00:39:12,843
‎再過50億年

330
00:39:13,683 --> 00:39:15,323
‎太陽就會耗盡燃料

331
00:39:19,883 --> 00:39:21,603
‎當核心崩塌

332
00:39:22,563 --> 00:39:24,043
‎太陽將會擴大

333
00:39:26,723 --> 00:39:28,283
‎變成紅巨星

334
00:39:31,563 --> 00:39:36,603
‎進而吞噬水星和金星等內行星

335
00:39:41,843 --> 00:39:43,883
‎當它朝地球的方向膨脹

336
00:39:44,763 --> 00:39:48,123
‎極大的引力將會粉碎月球

337
00:40:02,323 --> 00:40:05,323
‎在地球周圍留下一圈月岩

338
00:40:10,523 --> 00:40:13,603
‎我們星球的最終命運仍是未知數

339
00:40:18,483 --> 00:40:21,763
‎但肯定會迎來最後一次日出

340
00:40:25,683 --> 00:40:28,643
‎直到太陽的外層炸開

341
00:40:30,363 --> 00:40:32,203
‎嚥下它最後一口氣

342
00:40:40,083 --> 00:40:43,883
‎剩下的只會是將滅的餘燼

343
00:40:45,003 --> 00:40:46,603
‎一顆白矮星

344
00:40:46,683 --> 00:40:48,683
‎不到地球大小

345
00:40:49,323 --> 00:40:52,163
‎周圍環繞著發光的巨大星雲

346
00:40:55,443 --> 00:40:57,043
‎向宇宙發出信號

347
00:40:58,163 --> 00:41:00,323
‎我們曾在這裡

348
00:41:04,403 --> 00:41:05,523
‎但以目前來說

349
00:41:06,403 --> 00:41:09,603
‎我們的恆星仍會繼續照耀著我們

350
00:41:13,003 --> 00:41:16,243
‎持續到數十億年後的未來

351
00:41:17,243 --> 00:41:22,323
‎為地球萬物提供不可或缺的能量

352
00:41:30,163 --> 00:41:32,283
‎《我們的浩瀚宇宙》下集預告

353
00:41:33,923 --> 00:41:35,683
‎無論你是耀眼的恆星

354
00:41:38,123 --> 00:41:39,803
‎巨大的黑洞

355
00:41:40,963 --> 00:41:44,003
‎還是學習生活的黑猩猩

356
00:41:44,083 --> 00:41:46,323
‎一切都需要時間經營

357
00:41:48,123 --> 00:41:51,963
‎但你對這個神秘的維度
‎究竟了解多少呢？

358
00:41:53,243 --> 00:41:58,323
‎為什麼所有事物
‎都有過去、現在和未來？

359
00:41:59,523 --> 00:42:01,443
