1
00:00:00,160 --> 00:00:04,640
In our search for life, particularly here
in the solar system, we think we'll find

2
00:00:04,640 --> 00:00:09,920
microbial life first.
But beyond that, intelligent life,

3
00:00:09,920 --> 00:00:13,599
well out into the galaxy, what are we
going to find?

4
00:00:13,599 --> 00:00:18,000
What would it look like? Hi, I'm Jim Green, Chief Scientist at NASA

5
00:00:18,000 --> 00:00:22,800
and this is Gravity Assist. On this
season of Gravity Assist, we're looking

6
00:00:22,800 --> 00:00:28,160
for life beyond Earth.
I'm here with Dr Susan Schneider and she

7
00:00:28,160 --> 00:00:31,760
is the NASA Bloomberg Chair at the
Library of Congress

8
00:00:31,760 --> 00:00:35,600
and the William Dietrich Chair
distinguished professor

9
00:00:35,600 --> 00:00:40,879
at Florida Atlantic University, so today
we're going to talk about looking for

10
00:00:40,879 --> 00:00:45,600
life beyond Earth and
what it might be like. Welcome Susan to

11
00:00:45,600 --> 00:00:49,440
Gravity Assist.
Hi Jim, it's nice to meet you and be on

12
00:00:49,440 --> 00:00:52,960
your show.
What do you think life beyond Earth

13
00:00:52,960 --> 00:00:56,480
would be, intelligent life? What should we expect?

14
00:00:56,480 --> 00:01:00,240
I call it the post-biological approach in
astrobiology.

15
00:01:00,240 --> 00:01:04,879
Um, we all understand that

16
00:01:04,879 --> 00:01:09,760
if and when NASA finds life, it will
probably be microbial, you know and this

17
00:01:09,760 --> 00:01:12,320
is still pretty early in our own technological

18
00:01:12,320 --> 00:01:15,360
evolution.
Really, I mean just think it seemed like

19
00:01:15,360 --> 00:01:20,320
just yesterday
when we, um, had the television

20
00:01:20,320 --> 00:01:24,159
or the automobile or the airplane and
now look where we are.

21
00:01:24,159 --> 00:01:31,040
So it may be only a,
you know, blink of an eye in cosmic time

22
00:01:31,040 --> 00:01:34,479
really before we start enhancing our own

23
00:01:34,479 --> 00:01:38,159
intelligence
and becoming partly, if not fully,

24
00:01:38,159 --> 00:01:42,880
synthetic
ourselves. But it could be that the most

25
00:01:42,880 --> 00:01:46,280
intelligent civilizations out there are
in fact

26
00:01:46,280 --> 00:01:52,840
post-biological so they grew out of
originally biological civilizations like

27
00:01:52,840 --> 00:01:57,520
ourselves and
they're vastly smarter than us. Um, in

28
00:01:57,520 --> 00:02:00,960
fact they may be
so different from us that they're
