Summary

For every yellow star like our own there are ten times as many smaller stars. Red Dwarfs are the most common type of star, outnumbering all the others combined, and as we head out into interstellar space to colonize the galaxy, the exoplanets around these red alien suns may be the most common home for settlers.

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, check

0:30.6	The greatest and mightiest of civilizations will be around the larger stars, but the longest
0:35.4	lasting ones will be around the red dwarfs.
0:39.2	There are billions of galaxies, each containing many billions of stars, with billions and
0:44.6	billions of worlds around them all, and around three and four of those alien suns are red dwarfs,
0:50.7	so we should assume an awful lot of folks we'll live under a red sun in the future, and I thought
0:55.8	we should explore some of the difficulties and special challenges of colonizing such red dwarf systems,
1:01.4	with a particular focus on tidily locked planets around such suns, where one side exists in eternal
1:07.0	daytime and the other in perpetual darkness. First, we should start by recognizing that regardless of if it is a red dwarf or a blue giant,
1:16.1	our stars are white.
1:18.0	We just call them red and yellow and blue as means of categorizing them simply.
1:22.5	White light sources that are generated by heat, whether it's a sun or an incontacent
1:26.1	light bulb, have a temperature that
1:27.8	controls what the peak wavelength is for the light emitted, but the peak is not the entirety
1:32.1	of the light. For a glowing hot, red metal rod, that peak isn't even red, it's somewhere in the
1:38.2	infrared and there's just a little bit of red being given off that we can see. Most stars give off the
