1
00:00:01,126 --> 00:00:06,099
En dag, den sidst stjerne vil dø, 
og universet vil vende mørkt for evigt.

2
00:00:06,502 --> 00:00:10,262
Den vil sandsynligvis være en rød dværg, 
en lillebitte slags af stjerne,

3
00:00:10,262 --> 00:00:13,242
Det er også en af vores bedste spil 
at finde alien liv,

4
00:00:13,246 --> 00:00:17,506
Og må være den sidst hus af menneskelighed
før universet bliver ubeboelige,

5
00:00:17,744 --> 00:00:22,194
Så hvad kender vi om dem, 
og hvorfor er de vores sidst håb?

6
00:00:31,753 --> 00:00:35,493
I det mindste 70% af stjerner i universet 
er røde dværge.

7
00:00:36,005 --> 00:00:41,265
De er den mindste stjerner der ude,
med kun omkring 7 til 50% af massen 
af vores sol,

8
00:00:41,265 --> 00:00:45,515
ikke ret meget større end vores planet, 
Jupiter, som er stadig enorme, selvom.

9
00:00:45,994 --> 00:00:47,874
De er også meget dim.

10
00:00:48,516 --> 00:00:50,736
Den er umulig at se dem
med den nøgen øje.

11
00:00:50,976 --> 00:00:52,756
Du har ikke set en i den nat himmel.

12
00:00:53,376 --> 00:00:55,022
Selv med alle vores teknologi,

13
00:00:55,022 --> 00:00:58,002
vi kan kun klart observerer røde dværge 
i vores nabolag.

14
00:00:58,494 --> 00:01:02,244
Tilnærmelsesvis 20 af den 30 stjerner
tæt til Earth er røde dværge.

15
00:01:02,760 --> 00:01:06,746
