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

we're asked at 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,

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 question, though

we'll get started to break in just a moment too.

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

Good afternoon, everyone, and welcome to our monthly live stream Q&A here for SFI.

Today we'll be joined as usual by my wife and lovely co-host, Sarah Fowler, who will be reading

your questions off in the chat, as well as from some of our moderators like Sindry, who

has kind of to join us to get some questions on there.

And as usual, please try to get your questions in.

And is legible and straightforward a fashion as possible

to make a little bit easier for them to translate it over to us.

With all that said, we'll be going for all usual about one hour

with a break about halfway in between for about four or five minutes.

And we'll probably do a lightning round near the end to go through as many questions so we can to be in that chance to give

some time to. But as a warning, Sarah and I just got in from a one-week trip, so we're still

getting a little bit jet lag. So my apologies in advance, if I'm a little bit slower than

I should be to respond on some things or make any mistakes. And I said, let's get started.

Very good. Well, our first question was from Johnny Wings.
