Morgan Freeman stopped by The Daily Show with Jon Stewart Thursday night, and luckily he stayed alert and attentive. Though there to promote his new film, Now You See Me, the conversation turned to theoretical physics. That’s not of bad thing, of course.

“I don’t understand things like string theory, but multiple universes? I fully understand it – you understand it.” said Freeman when asked about how much knowledge he has on the topic.

Check out the full convo below, which dives into the singularity of the universe.

As host of the documentary series Through the Wormhole, Mr. Freeman should have this sort of interest, right? Right. He also recently hosted the Fundamental Physics Prize gala in Geneva, where he had the chance to spend a little time with Stephen Hawking.

“He doesn’t talk a lot,” said Freeman.
