1
00:00:00,801 --> 00:00:02,769
Male narrator: In the
beginning, there was darkness.

2
00:00:02,771 --> 00:00:04,070
And then... bang.

3
00:00:04,072 --> 00:00:08,775
Giving birth to an endless expanding
existence of time, space and matter.

4
00:00:08,777 --> 00:00:13,067
Every day, new discoveries are
unlocking the mysterious, the

5
00:00:13,069 --> 00:00:21,332
mind-blowing, the deadly secrets
of a place we call the universe.

6
00:00:21,334 --> 00:00:25,567
The numbers of the universe
boggle the human mind.

7
00:00:25,569 --> 00:00:28,837
In the observable part of the
universe, there is something

8
00:00:28,839 --> 00:00:34,277
like 100 billion galaxies--
Each with billions of stars.

9
00:00:34,279 --> 00:00:38,117
The Andromeda galaxy is about
2.5 million light-years away.

10
00:00:38,119 --> 00:00:39,954
The Earth is orbiting the Sun

11
00:00:39,956 --> 00:00:44,628
at a speed of about
66,000 miles per hour.

12
00:00:44,630 --> 00:00:48,101
Narrator: Most of us give up
even trying to comprehend such

13
00:00:48,103 --> 00:00:52,938
titanic sizes, distances,
and speeds.

14
00:00:52,940 --> 00:00:57,178
But are there ways to bring the
sweep of the cosmos down to

15
00:00:57,180 --> 00:01:05,150
Earth to help us understand how
big, how far, and how fast?

17
00:01:16,964 --> 00:01:23,972
Planet Earth-- For all its wide
expanses, deep seas, and massive

18
00:01:23,974 --> 00:01:29,079
mountains-- Amounts to a speck
of dust when stacked up against

19
00:01:29,081 --> 00:01:33,687
the immensity of the cosmos.

20
00:01:33,689 --> 00:01:35,322
The observable universe

21
00:01:35,324 --> 00:01:38,860
contains on the order of
100 billion galaxies.

22
00:01:38,862 --> 00:01:46,370
And then each galaxy, like the Milky Way,
contains on the order of 100 billion stars.

23
00:01:46,372 --> 00:01:49,174
The numbers quickly get up into
the millions and then the

24
00:01:49,176 --> 00:01:51,744
billions and even the trillions.

25
00:01:51,746 --> 00:01:53,112
And by then, we've really lost

26
00:01:53,114 --> 00:01:56,350
all sense of what
that really means.

27
00:01:56,352 --> 00:02:00,188
Narrator: The human mind is
finely tuned to deal with the

28
00:02:00,190 --> 00:02:03,292
scale of day-to-day experience.

29
00:02:03,294 --> 00:02:07,731
The brain can understand
traveling 50 miles in a day.

30
00:02:07,733 --> 00:02:09,732
But what about 500,000?

31
00:02:09,734 --> 00:02:12,569
And a person may know what it's

32
00:02:12,571 --> 00:02:15,472
like to move at 100
miles per hour.

33
00:02:15,474 --> 00:02:19,976
But what about 100 million?

34
00:02:19,978 --> 00:02:23,146
Numbers like millions and
billions, and certainly

35
00:02:23,148 --> 00:02:26,115
trillions, are very hard for
most people to imagine,

36
00:02:26,117 --> 00:02:27,917
because, frankly, most of us

37
00:02:27,919 --> 00:02:32,588
don't have billions or
trillions of anything.

38
00:02:32,590 --> 00:02:36,660
Narrator: So how can we ever
know the universe if our

39
00:02:36,662 --> 00:02:42,066
brains can't really comprehend
its massive scale?

40
00:02:42,068 --> 00:02:45,304
Doing scale models of objects
in the universe is really

41
00:02:45,306 --> 00:02:49,409
helpful, bec
