You know what time it is. It's time for Ask Us, Spaceman. I'm your host, Paul Sutter. You've got questions and I've got answers. You know how this show works, but I'm going to tell you anyway, because I don't care.

You go online to Twitter at Facebook.

Use the hashtag Ask a Spaceman, Send Questions.

If you're not the Twitter in or Facebook in type, you can also email me, Ask a Spaceman at Gmail.com.

You can also send a letter, P.L. Box 3322, Columbus, Ohio, 4322210. Yeah, I'm, I would love it if I actually got a letter that had just a simple question that I answered on this show. Can

someone make that happen? Just do that. Just do that. You're really good at doing stuff.

We have a very simple goal with this show, complete knowledge of time and space.

On the road to that is, I have a confession to make.

I just wrapped up two episodes on the cosmic microwave background.

And I was about, I was halfway through like sketching out a third episode.

Unprecedented in the history of this series, but I was going to do three episodes on the

Cmb.

And I was going to focus on how we actually detect the CMB, how we actually do our

measurements and stuff. And then I kind of realized it was getting a little self-indulgent.

Like, I don't know. I was doing the CMB, like all of you asked, and you asked because I asked

you asked, but you asked which counts,

so I did episodes on it.

But I was really digging in, and it was starting to get a little bit technical.

And the last episode was, like, super heavy.

Like, there were complicated jargon terms, weird physics.

There were, you know, conceptions about the nature of reality and time and space

over 13 and a half billion years of evolution and episode went pretty long and it was it was just a
