Getting that much science into 17 minutes of national television is an achievement all by itself.

6:33 Neil DeGrasse Tyson giggling with glee. My life is complete.

[mrghsgaming]

I love how Neil when still gets excites like a 14-year boy on sugar rush on science explanation

[tiagole]

3:10 Neil's like:"I'm about to end this man's whole career"

[soapyseth]

Gotta admit Stephen’s counter argument got me a little hype😂

[Mersault]

I love that Neil comes back to the show so much.

[westfal]

3:17 I love how Neil just starts laughing 😂😂

After watching this and then talking to Scientists at the University.
"You know, I'm something of a scientist myself."

[meows_and_woof]

Imagine you steal an ashtray from alien ship, come back home, look at it and see Made in China😁

[ThatDarnKittehGaming]

Neil doesn't need to drop a mic. * drops book *

[umachan]

I love it when these two get together. You can tell they're having fun with the whole thing.

[MiladJPanah]

What Stephen said about the "thinking creature starting the process" was so freaking good. This is so deep I can't believe we are not talking about this shit every day.

I feel like they probably don’t have a lot of spare time between their full time gigs for something like this, but I’d LOVE for Tyson & Colbert to do a full TV series together. Their chemistry is so good, and Tyson is never not enthralling to listen to.

Make it a show about space or whatever really, I doesn’t matter, I just want a weekly show with them interacting with each other. I’d pay good money for that.

6:32 well that’s another GIF for the archive if I ever saw one.

And about 50% of said archive consists of Neil DeGrasse Tyson already; the man is like a treasure trove for these things.

[Gavriel-ogjv]

2:04 I definitely love this type of argument: sounds like arguing, but it is funny and straight to the point all at the same time.
There should be WAY more like this everywhere.

[prathameshbhambure]

I just love him. He makes me fall more and more in love with astronomy.

[AceOfROMs]

I love how much fun Stephen is having here.

[derpmcgerp]

Always love his genuine common-sense approach to talking about aliens. "If you find yourself on an alien ship, take pictures and/or try to grab something to bring back to Earth!"

6:59 Neil looks like the grandfather you never knew you wanted.

[naschsemler]

“How do you know?” I really felt that !
