In Ohio's capital, astronomer Stuart Kingsley is conducting an independent search for visual

2
00:00:07,560 --> 00:00:08,560
signs of air.

3
00:00:08,560 --> 00:00:28,580
In the

4
00:00:29,580 --> 00:00:35,660
extraterrestrial intelligence by updating an idea discarded in the 1960s.

5
00:00:35,660 --> 00:00:36,660
Laser communication.

6
00:00:36,660 --> 00:00:41,500
I'm looking for a regular pulsation in the optical spectrum.

7
00:00:41,500 --> 00:00:46,740
Basically a bleep bleep bleep, rather like an interstellar heartbeat.

8
00:00:46,740 --> 00:00:52,860
Traditionally the search for extraterrestrial intelligence or ETI uses radio telescopes,

9
00:00:52,860 --> 00:00:55,020
programmed to pick up anomalous sounds.

10
00:00:55,020 --> 00:01:00,180
But Kingsley believes that our first two-way communication without her space will be visual.

11
00:01:00,180 --> 00:01:01,980
Lasers are more for point-to-point targeting.

12
00:01:01,980 --> 00:01:05,620
It gives you a very narrow beam even over interstellar distances.

13
00:01:05,620 --> 00:01:12,660
So that's actually why I think the preferred technology for ETIs to communicate with other

14
00:01:12,660 --> 00:01:14,900
stars is lasers.

15
00:01:14,900 --> 00:01:18,620
And Kingsley is confident his search will not be in vain.

16
00:01:18,620 --> 00:01:20,140
We are going to discover something.

17
00:01:20,140 --> 00:01:24,380
Well that's going to be a major news story because that means we are not alone.
