Summary

The Search for Extra-Terrestrial Intelligence, SETI, relies on looking for signals from distant alien worlds where even very powerful signals can weaken to near nothing. We'll explore today how we, or extraterrestrials, might get around this problem, be it by immense star-powered transmitters or by using laser communication beams.

0:00.0	Hello, SFIA audio listeners. In this month's Nebula exclusive, Big Alien Theory,
0:05.0	we're asking the reason alien civilizations might be rare is because most aliens are huge.
0:10.0	To hear it and every episode early and add free, plus hours of bonus content,
0:15.0	check out go.nebola.t.v.tv slash Isaac Arthur.
0:20.0	This episode is sponsored by Raycon.
0:23.3	The galaxy is a big place, a billion billion kilometers across.
0:28.9	So if anyone was out there trying to talk to us, a signal would be very faint.
0:33.4	So how would they go about boosting the transmission?
0:51.5	No, So how would they go about boosting the transmission? So today we return to the Alien Civilization series to look at the notion of talkative
0:55.6	aliens, aliens who actually wish to speak with us, as well as the general notion of
1:00.2	interstellar communication.
1:02.6	We'll be considering the available options under known physics, but also discussing some
1:06.6	of the more theoretical scenarios like fast and light communication.
1:10.6	We're also teaming up today with Alberto Caballero, hosts the Exoplanet channel, and Parallax
1:15.5	Nick, who will be looking at optical and laser setting in parts 2 and 3.
1:19.9	They'll explore how we might use lasers to talk to aliens and how we might detect them
1:23.7	if they were trying to chat with us, as well as why this is probably the most promising way to search for aliens. If you're not already subscribed to their shows,
1:31.5	make sure to give them a like and a subscribe when you head over for Parts 2 and 3.
1:35.3	Also, since this is a 3-parter, we'll be here for a bit, so now is a great time for a drink
1:41.1	and a snack. SETI is the acronym for the search for extraterrestrial intelligence, a collective term for
1:47.6	several loosely affiliated scientific efforts.
1:50.6	There is a prominent group called the SETI Institute that is very well known for their
