Neil deGrasse Tyson and Terry Crews Answer Your Questions

What does it take to truly thrive on Mars? Neil deGrasse Tyson and Terry Crews answer grab bag questions about Mars, magnetic fields, photons, Hot Ones spicy wings and the entropy of muscles.

We discuss whether we could develop technology to create an artificial magnetic field to shield future Mars colonists. Would living underground on Mars defeat the purpose? They also explore Earth's ever-shifting magnetic poles, what happens when the field weakens, and why humans don’t have to fear an imminent magnetic flip.

We explore the balance between muscles and entropy in the universe, examining whether physical strength still has value in today’s world—and if muscles are even necessary for space survival. From gamma rays’ interactions with space curvature to the effects of low gravity on human physiology, we touch on how space impacts everything from fitness routines to bone density. They share their experience facing the notorious Hot Ones’ spicy wings challenge and Neil’s spicy aftermath in his own bathroom.

Finally, Neil and Terry push the limits of our understanding, speculating on what lies beyond the observable universe and why the cosmos may look very different beyond our cosmic horizon. We close with stories from Terry’s latest projects and his journey to success, sharing wisdom from his memoir Tough.

This makes me want to read a textbook while doing push ups. Y’all need to collaborate more. This is amazing

[UnheiligTube]

I'm quite suprised and delighted that Terry Crews has a good grasp on science stuff. I don't often see actors talking about science and space with that curiosity. Terry just asks and listens and then has a genuine follow-up question because he really wants to learn more about this. Such a nice guy.

I live in Pasadena and my mom has come across him a couple of times. Every interaction she had with Terry shes said that he was really nice and asked to be treated like a normal customer. She understood that he didnt want to be treated as a celebrity in the town he lives in. He appreciate it every time he came in :)

THIS WAS ONE OF THE BEST STARTALKS EVER! PLEASE BRING TERRY BACK!!!

[kushclarkkent]

It is physically impossible to dislike Mr. Crews! A legend in every sense of the word. And a great dad!

Tears " i didn't know I could act until I was thirty years old. Thirty. I never attempted acting before i was 30. And I did not know it was my destiny." 😢😭 my heart! You got me right in the heart.

This was so fricking good! I usually don't enjoy videos without Chuck but Terry just showed he's just as good a fit with Neil as Chuck is! Now I want to see Neil, Chuck and Terry do a Startalk together! Please guys?! I think after the past few months we deserve it! At the very least please come back again soon Terry!

Fun compass fact: Airport runway numbers typically align with their magnetic direction (Runway 18 is a magnetic South-North running runway. The opposite end would be 36). Every so often they have to renumber the runways with new markings to correct for the drift.

I don't know what kind of person is Terry on his every day life, but in every appearance he brings such and happy and positive energy, I cannot but think he's an amazing person.

[danAames]

Never thought I'd see the great President Dwayne Elizondo Mountain Dew Herbert Camacho on Startalk

[pepperinyoureye]

Two of the most likable celebrities on the planet, together for 42 minutes of joyous conversation. Maybe the future is bright 🙌

[shadowsstreamclips]

Never thought I could be this fast at a star talk, Terry you are the GOAT!

I’ve watched startalk soo many times that I literally have an answer to every question. Thanks Neil for making me a bit wiser

[bonniebernido]

I would love to have terry come back, his humor and open mind was absolutely perfect!

[cozmicpfunk]

Hi Terry and Neil- Terry, you probably don't remember me but we met on Idiocracy, I was in 6 scenes including the White House front lawn party and Pennsylvania Ave. I was easily seen in the Guitar Army. You were so nice to every one, I never forgot how great of a Human you are. Amazing to see you with Neil, another Amazing person. 2 for the price of one, the deal of that day! Love you both <3 John Patrick

[JumboFPS]

Neil drunk in college with his face on the bathroom floor is hilarious 😂

[AndorranStairway]

What an incredible honor to have President Camacho on the show!
