1
00:00:05,190 --> 00:00:01,990
can i ask you to first off explain the

2
00:00:06,630 --> 00:00:05,200
term grab a alien

3
00:00:08,629 --> 00:00:06,640
sure so

4
00:00:10,790 --> 00:00:08,639
when we look up in the sky

5
00:00:11,830 --> 00:00:10,800
the universe looks empty

6
00:00:13,350 --> 00:00:11,840
and

7
00:00:15,829 --> 00:00:13,360
we can draw some conclusions from that

8
00:00:17,670 --> 00:00:15,839
that's data

9
00:00:20,230 --> 00:00:17,680
data about

10
00:00:22,710 --> 00:00:20,240
one kind of alien but not another and i

11
00:00:25,349 --> 00:00:22,720
want to distinguish the two so i will

12
00:00:27,509 --> 00:00:25,359
say it's data about the loud but not the

13
00:00:30,710 --> 00:00:27,519
quiet aliens

14
00:00:32,790 --> 00:00:30,720
away

15
00:00:35,270 --> 00:00:32,800
they're small they're staying small they

16
00:00:37,110 --> 00:00:35,280
don't last long they're not doing much

17
00:00:39,750 --> 00:00:37,120
they're really hard to see

18
00:00:43,030 --> 00:00:39,760
so a big empty universe is consistent

19
00:00:44,950 --> 00:00:43,040
with a lot of quiet aliens out there

20
00:00:47,190 --> 00:00:44,960
however there's another kind of alien

21
00:00:50,150 --> 00:00:47,200
this is an alien which once it appears

22
00:00:52,389 --> 00:00:50,160
starts to grow expand rapidly and then

23
00:00:55,430 --> 00:00:52,399
in the volume it touches it changes that

24
00:00:56,709 --> 00:00:55,440
volume makes a big difference

25
00:00:58,470 --> 00:00:56,719
that's the sort of thing life has done

26
00:01:00,389 --> 00:00:58,480
here on earth and humans are doing on

27
00:01:01,510 --> 00:01:00,399
earth that is when we go places we

28
00:01:02,709 --> 00:01:01,520
change things we make them look

29
00:01:05,350 --> 00:01:02,719
different

30
00:01:07,429 --> 00:01:05,360
uh that's the kind of life

31
00:01:09,030 --> 00:01:07,439
and civilization that we don't see in

32
00:01:11,750 --> 00:01:09,040
the universe and so

33
00:01:14,070 --> 00:01:11,760
loud aliens are what we're not seeing

34
00:01:16,310 --> 00:01:14,080
and that's the data to think about so

35
00:01:17,830 --> 00:01:16,320
grabby aliens is our specific
