Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,

we're asking the reason alien civilizations might be rare is because most aliens are huge.

To hear it and every episode early and ad-free, plus hours of bonus content, check out

go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.

Good afternoon, everyone, and welcome to the SFIA monthly live stream Q&A.

We'll get started in just a moment, but go ahead and start getting your questions in the chat

window so our moderators can start relaying those to me as soon as we start.

Please try to keep the questions concise and watch your spelling and try to be polite to others

in the chat.

We usually go for about an hour so you probably want to grab a drink and a snack, though

we'll take a break about halfway through too.

With all that said, welcome and let's get started.

Okay, hopefully this work this time. For those of you who tuned in writers, we got started, we had a little bit of a technical glitch getting started and it kind of messed up our ability to go. So we went to pull it back out of that. I gather we did go live for a minute or two.

For those of you are catching this after the fact, there was a short mess up there.

We're going to get started in just a moment here. For those of you who did not know, we skipped

the live stream last month, and this is our first month back in the new studio and a bit of a

rush set up because I wasn't originally planning to do a live stream in May because I was planning to be at the International Space Development

Conference down in Dallas, but that got canceled because of the virus. So as we go through today,

we're going to have my wife Sarah reading the questions off to me as we go, and we'll have me

repeating them back just in case we don't have the good enough

mic set up because again we're just getting started with the studio. I should probably also

mention as we get going that we did hit 500,000 subscribers this month and I just want to thank
