Answering Fan Queries About Strange Matter, the Insides of Black Holes & More

What could we do to hide from the aliens? Neil deGrasse Tyson and comedian Chuck Nice answer fan questions about human radio wave signals, strange matter, universes inside black holes, and other physics questions!

Could a spaceship constantly accelerate? We talk about retrorockets, the Equivalence Principle, and space fueling stations. Learn how the paths of projectiles don’t actually follow a parabolic arch. Plus, how do photons experience redshift while also being destroyed upon creation?

Are we on the other side of another universe's black hole? What is the difference between the horizon of our universe and the event horizon? What is strange matter? We break down the types of quarks and the mysterious things in particle accelerators. Plus, learn where the word “quark” comes from.

Do gas giants have a solid core made of different things than ours? Find out about the formation of the solar system, Maxwellian distribution of velocities, and how big Jupiter’s atmosphere is. We also explore human radio and TV signals and how we could encrypt our signals so aliens don’t hear us. How many cosmic discoveries are made by people with no formal training? Can enthusiasts still contribute to science? We also discuss what needs to be revised about the model for the start of our universe. Plus, learn how aliens received the wrong directions to our solar system.

This is easily the most entertaining science program that i have ever watched. The chemistry between Neil and Chuck is so good that i laughed while gaining a great deal of knowledge. These are truly a treasure.

[LiquidChamploo]

One of the smartest people I watch just said "I don't know the answer to that, we'll have to ask someone else."
I can't quite put my finger on why that's so amazing to me.

[Ikonicre_Moonshield]

Having Neil is Nice. Having Chuck is Necessary. The secret ingredient of Galactic Gumbo. ....gairronntee 😂

[valiantwarrior]

I love it when Neil laughs. It just seems so genuine. The full body laugh.

[cordestian]

I tried watching an episode with comedians other than Chuck and I couldn't get through it. Chuck works so well because he's hilarious, and smart enough to follow the discussion and participate on a somewhat educated level, as well as a humorous one. His jokes are smarter than other comedians I've seen on the show.

Love you chuck!

[syedwt]

Perfect duo, Chuck plays his role perfectly as a funny layman and Neil can explain things so simply.

You can change the perceived red shift of the photon by changing your reference frame. For example, if you move closer to a black hole, you’ll see the photon red shifted. This means the redshift of the photon is a consequence of your observation of the photon, not a change in the inherent properties of the photon.

[bobbyjones]

This is one of my favorite shows on YouTube! I’m hooked, and I cannot lie.😂

[zanebertoli]

Love the expanse drop. Right when he said flip and burn, I was yelling "the expanse!!" So glad he said it in the discussion. The expanse is the best show ever, highly recommend. Good books too.

[zacharyimpero]

These two are the absolute perfect combo to listen to.

[faaa]

I’m only 40 seconds in and Chuck has me rolling on the floor 😂

[VincentSilva-uvjj]

Hi Mr. Degrasse....I've been watching you since I was in school & you were on the cosmo show & just so happy to be able to continue learning from you & you are the reason I fell in love with science & biology!!! Believe it or not but you've been a big part of my quest of knowledge of the "COSMOS"

[davidvenegas]

Have to say, I think this is the first time I have seen NdGT stumped on a question regarding the photon vs time dilation. Good question.

[travailier]

Hope these question based shows become more frequent... they're fascinating.

[UP-To-The-Time]

Chuck is a beast, love this guy, he gives the show life

[marcoottina]

5:10 "Ad Astra" means "to the stars" and it's written on the Kansas's Flag. And then Chuck made me .. chucking 😂

[StarTalk]

If Earth needed to hide from prying eyes in the cosmos, what kind of technology do you think we could use for planetary cloaking? 🛸🔍 Drop your wildest ideas below—let's see how creative our StarTalk community can get!

[JerkleCirc]

The Expanse is just the best scifi show, period. Enthralled the entire time. Book series is even better.

[HotelPapa]

"Ad astra", In full. "per aspera ad astra" (through rough roads to the stars) was an aphorism used since Roman times (it was coined by Seneca the younger). That's what puts in on the Kansas state flag, not actual star travel.

The universe continues to amaze us
Love hearing Neil and Chuck
