On a typical day at school,
1
13000
5000
00:18
endless hours are spent
2
18000
2000
00:20
learning the answers to questions.
3
20000
2000
00:22
But right now, we'll do the opposite.
4
22000
3000
00:25
We're going to focus on questions where you can't learn the answers,
5
25000
3000
00:28
because they're unknown.

I used to puzzle about a lot of things as a boy.
7
31000
3000
00:34
For example, what would it feel like
8
34000
3000
00:37
to be a dog?
9
37000
2000
00:39
Do fish feel pain? How about insects?
10
39000
3000
00:42
Was the Big Bang just an accident?
11
42000
4000
00:46
And is there a God?
12
46000
3000
00:49
And if so, how are we so sure that it's a He and not a She?
13
49000
4000
00:53
Why do so may innocent people and animals suffer terrible things?
14
53000
3000
00:56
Is there really a plan for my life?
15
56000
3000
00:59
Is the future yet to be written,
16
59000
3000
01:02
or is it already written
17
62000
2000
01:04
and we just can't see it? But then, do I have free will?
18
64000
3000
01:07
Who am I, anyway? Am I just a biological machine?
19
67000
3000
01:10
But then, why am I conscious?
20
70000
3000
01:13
What is consciousness? Will robots become conscious one day?
21
73000
4000
01:17
I mean, I kind of assumed
22
77000
3000
01:20
that some day I would be told the answers to all these questions.
23
80000
3000
01:23
I mean, someone must know, right?
24
83000
4000
01:27
Huh. Guess what? No one knows.
25
87000
4000
01:31
Most of those questions puzzle me more now than ever.
26
91000
3000
01:34
But diving into them is exciting
27
94000
3000
01:37
because it takes you to the edge of knowledge,
28
97000
3000
01:40
and you never know what you'll find there.

So, two questions to kick off this series,
30

01:47
questions that no one on Earth knows the answer to ...
31

Text: How many universes are there?
32

Why can't we see evidence of alien life?
