So a scientist, an atheist, and a Catholic walk into a bar...

This should be a monthly installment on the show. Debunking with Degrasse. I accept PayPal.

Oh my god Stephen not only namedropped Ringworld, he explained its entire premise in under 18 seconds, he's amazing

Disney launched it out there as a publicity stunt for the new Star Wars film

I could watch all three of these guys for hours! Great set of minds there.

If you want to see more of Stephen interviewing Neil search youtube for the 1 hour and 24 minute video at the Montclair Kimberly Academy. The interview starts at 6 min 30 seconds.

"I read this from Buzzfeed" Gold

"I read this on buzzfeed" lol

Stephen: *nerds out about the ringworld and mentions God* Tyson: *scientific, astrophysicist knowledge and reasoning* Seth: *Buzzfeed*

All three of them are different kinds of genius!

"I READ IT ON BUZZFEED" God I love Seth for that line.

I thought they were going to announce Cosmos season 2...

I like how Stephen was wearing one of Neil's vests lol

Very cool interview! Love the obscure science fiction reference

No one else but Steve can explain a complex alien civilization in 10 seconds.

Awesome. What other host talks about cool stuff like that? Long live nerds.

BOOM! This is why I love Colbert. He brings the geeky into the main stream. I love the Ringworld reference. He could have dumbed it down and said we found Halo but he kept it real.

Where's deGrasse? Don't worry, I think Seth brought some.

Are there more interviews or talks with MacFarlane and Tyson? I feel like they would make an amazing duo. Both have equal enthusiasm for science and humour while Tyson is mostly knowledge with some gteat humor and MacFarlane is mostly humour with great science knowledge. I feel as though they could riff off of each other all day in a great way. It could be equally hilarious and educational.

Im going to cry because thats 3 of my favorite people on one stage. I cant

NDT is literally my favorite human being on the planet.

These 3 should have a weekly segment on the show where they just talk. 10/10 would watch

Neil, Seth and Stephen should have their own show; what a great panel.

Dammit Neil, he has a picture

"I read this on BuzzFeed" lmao

Ringworld? Ha! This is obviously a Dyson Sphere in mid construction. Duurrr! Get with it, Stephen!

I could watch just hours of Neil and Stephen together. 💖

Ladies and gentleman, Stephen Colbert's Late Show is in full swing.

star studded video!

THREE OF MY FAVORITE PEOPLE PLEASE DO MORE THINGS TOGETHER

Okay, this is now one of my fav videos on YT

its always fun to see stephen out geek neil.

I just read Ringworld a couple weeks ago... Once again, Colbert's timing is spot on!

I could listen to those two banter for days!

Omg the brilliance and talent between those three wow

I love how geeked-out Cobert gets in this segment!

Very cool to hear a ring world reference in any medium

Stephen is love, Stephen is life.

Love Ringworld so much

"Theyyyyy think it's the Borg" XD

"i read this on buzzfeed okay" lmfao perfect

Ringworld reference! I love it! Also consider the scope of Kepler, it's covering such a small portion of our "detectable sphere"; what other facinating questions await the prying hexagonal eye of the future James Webb Telescope?! Science Rules! Hail Sagan!

haha now thats an interesting setup for a conversation ;-).

It's the Ringworld! I have a picture!

I got ringworld once at camp. Oh wait. Ringworm. Never mind.

"One unlikely, but possible answer." That's not a statement that needs to be clarified. It already was.

There needs to be more geeking out with these 2.. 3 even :)

These three need to start their own show together

Or possibly ancient remnants of our past.

+1 Internets to Stephen for the Niven/Ringworld reference!

Somehow I knew Colbert would be familiar with Ringworld!

Love Neil's "Starry Night" tie! Very appropriate for what they are talking about.

Neil deGrasse Tyson's tie, & Stephen Colbert's vest are spectacular.

You should have Neil on regularly, you guys make great TV

“They think it’s the borg .” Haha classic seth

0:58 the eye clap 👏 👀

Cleveland Brown in the flesh.

Omg. Neil and Seth together is absolutely amazing!

So..after that what happened!? Next clip plz!?

Love his tie

could you imagine being able to impress tyson seth has to be baffled

Where is the rest of this interview?

If you want to see more of Stephen interviewing Nei,l search UKposts for the 1 hour video at the Montclair Kimberly Academy.

but what if it is really a borg LOL

Stephen is wearing Tyson's Vest :-) Cuuuuuute

it so wierd i was reading about Dyson spheres randomly on wikipedia like 5 days before i even heard about this discovery...

"It's dimming by 22%". The only thing I thought when he said that was a 'Your mom is so fat' joke.

Great to see Neil gladly lent Stephen his Cosmic vest.

These guys need to make a movie

where can i watch full ep of this

so Halo 1 is loosely based off Ringworld?

RingWorld just blew my mind

Love that Stephen is wearing Tyson's vest

Favourite physic with my favourite tv maker❤️

Stephan has his facts straight in these visits with Neil. I'm impressed.

Colbert lays it out on Tyson!

Ringworld!!! But were not looking at it exactly edge on, but slightly obliquely. Even though in real life the ring would collapse into a sphere.

Haha, Colbert is wearing a star vest like Neil usually does.

Neil Tyso : Stewie invented a time machine! Seth MacFarlane : Actually he created the universe.

is that a polaroid onestep 2 in the lower left corner, 2 years before it was invented???

Reminds me of Nino and his pictures of himself cleaning.

"gooooooooooodddddd," when nebulous and unexplained. no further questions

"I have a picture of it" 😂😂😂😂

I didn't think it was possible to love Colbert more and then he goes and goes Ringworld on us! Complete with a picture no less. Awe inspiring. Wait a minute... if he's right does that mean the Pak fleet is headed our way?

does anyone have the full version of this?

1:48 I love that dig at Buzzfeed.

As much as I love Tyson, you can tell he would have been pretty annoying at school lol

I had a nerdgasm when Colbert pulled out the Ringworld picture.

I read this on buzzfeed classic!!

Wow that was some really epic "geeking out".

One! or two... rings to rule them all!

Just watched The whole thing on CBS app. God I love Colbert and Neil and Seth.

That is great. THAT IS GREAT!!

these three men just bullshitting science and anything else for hours would be such a great show.

Hell yea Larry Niven call-out!

I do not know why, macFarlane/Degrasse is an awesome combination

Oh, Tyson... Can't you just let us hope?

These latest discoveries are making me really excited about all the other unknowns still out there.Go science!!! PS:Dear US gov't pls do sth abt NASA's budget...pls

Stephen's outrage when Neil questioned the Ringworld

Stephen's rant here would have been perfect for The Colbert Report.
