Ask A Spaceman Ep. 194: Does the Universe Rotate?

<p>How do we know that the universe doesn’t rotate? Why would it matter if it did? What does all this have to do with time travel? I discuss these questions and more in today’s Ask a Spaceman!</p> <p> </p> <p><strong>There’s a short audio problem at 20 minutes, 12 seconds that I can’t fix. I’ve left it in just in case you can make sense of it. “Not a blank check here, but it allowed to rotate the Universe.” Is one part of the audio. “We use artificial models all the time in physics that…” is another part. Mixed together such that I have trouble teasing out what he’s saying. I’m sure it was good stuff.<span class= "Apple-converted-space"> </span></strong></p> <p><strong>- Richard Drumm, 365 Days of Astronomy Editor.</strong></p> <p> </p> <p>This episode is sponsored by BetterHelp.
