What happens to quarks during spaghettification? Neil deGrasse Tyson and comedian Chuck Nice answer fan questions about positrons, how we got the speed of light, where the Big Bang took place, and more!

How is the age of the universe quantifiable in Earth years? A patron asks about best practices when reaching out to physicists. Why are the origins of the universe still a mystery? Could our whole universe be inside a black hole?

Could a photon from its frame of reference see galaxies beyond our horizon? What would it be like on a planet surrounded by black holes? Learn about the dispersion of matter during the Big Bang and what happened to the place where the Big Bang occurred. We discuss the power to reorganize atoms and how to determine a planet’s north and south poles using the Right-Hand Rule.

What are some examples of energy becoming matter in our universe? Learn about positrons, thermonuclear fusion, and the moment energy became matter during the Big Bang. We break down how we got the speed of light and Ole Rømer’s observations of Jupiter’s moons.

    Which part of this Grab Bag do you want us to dedicate an entire episode to? 🤨

    Proper credit to the person who asked a question that make Neil say "I gotta talk to some people about this." Mitchell Adkins (sp) wins StarTalk.
  • @seventoast
    I think I speak for all fans of StarTalk when I say we will never get tired of Bayou Chuck. I garrontee!
  • @oaguilera81
    Damn! Chuck was on fire in this episode 😂😂😂😂😂
  • @AqueleRod
    This is the best duo on the internet!

    The Cajun Chef on PBS was Justin Wilson (April 24, 1914 to September 5, 2001). His cooking show was called “Louisiana Cookin’”. I absolutely Loved watching his cooking show… and I had never even tried Cajun food at that point. My all time favorite thing he would say was: “Tell you what I gonna did.”. As well as his all around catchphrase “I Gar-on-tee!”. Plus whenever he would put something alcoholic in the food - he would always take a drink right after: “A little for you, and a little for me.” I swear that sometimes by the end of the show he seemed like he was totally drunk. LOL!!!
    He was also a recording artist. He composed the music for his cooking show, and released one album of Christmas songs, and several comedy albums. He also appeared on the Ed Sullivan Show. He also did a series of commercials for Ruffles Cajun Spice potato chips.

    Been watching StarTalk for years now. Chuck stated as the everyman. The layperson comic relief that we could all relate to....now he's become an expert in his own right. Goes to show if you surround yourself with good company, it rubs off.

    "A little bit of wine in the food and a little bit of wine in me, I gar-on-tee!" Justin Elmer Wilson (April 24, 1914 – September 5, 2001) was a Southern American chef and humorist known for his brand of Cajun-inspired cuisine, humor and storytelling. One of my PBS favorites. :)
  • @brozbro
    When Chuck is on Comedy Central, Neil should join him onstage with interesting scientific facts.
  • @Steve-hu8px
    Don’t get me wrong, I LOVE science, and I can watch dry science material alllll day, but the addition of Chuck as the comic relief just absolutely MAKES this show. And now he’s basically an expert himself lol. Just goes to show that the people you surround yourself with makes a HUGE difference in your own life. So, thank you Neil and thank you Chuck for making the BEST duo on the internet. Absolutely LOVE watching you guys. Keep it up! ❤
  • Chuck Nice is on fire this episode; nonstop laughs! Thank you!! ❤❤❤
  • @lemongavine
    Need a follow up to that quark question after Neil talks to his people
  • @jasmined4973
    This is my favorite format. When they’re in person together. Talking about cool science stuff I would never understand if it weren’t for them 😂
  • @Bostonmerch
    Having Chuck is great. The comedy and exchanges really keep us engaged and make the topics fun. Thank you for all that you both do! I truly hope there even one person that has listened to you, was encouraged, and ultimately solved an unknown or some other way added value to humanity.

    Professional chef here:

    The secret to any good restaurant dish is the follwing:
    Many years of training and experience, on the job and sometimes in culinary school;
    Many hours , possibly days, of trial and error, refining, and taking notes

    A lot of knowledge and tradition passed on through the generations
    (The famous Newton quote applies: "If I see further than others have before, it is only because i stand on the shoulders of giants.")

    Hours and hours of prep and hard work by the a collection of people; for example, the farmer who raised a cow, the butcher who processed the meat, and depending on the situation, day shift may have spent hours doing preparation before whoever cooks it for the customer gets their hands on it. Things might have to marinade for hours, or be partially pre-cooked, and even just things like portioning and measuring ahead of time can make a huge difference and is often done during the day before the resaturant opens / gets busy.

    And last but not least, perhaps the most important 'secret' to great food:
    Quality ingredients (and uusually lots and lots of butter)

    It's quite possible there's something I forgot to mention but the point is, it takes a team and a lot of intermediate steps and all of them are important :)
  • @showbizz7539
    That was awesome to see him hear a question, and end up answering with, "I have to talk to some people about this"
  • @rlems4772
    I like this so much, amazed by Neal and hillarius humor from Chuck,even here in Amsterdam!!
  • To answer your question Neil, I live in London Ontario Canada. It is an actual place. My London is called "The Forest City" because of our beautiful trees. It is located at the forks of the Thames River (just like London England is at the forks of their Thames river). I'm a big fan. Peace, Calvin.
  • Such a fundamental thing is the speed of light, and until I watched this episode, I never knew how it was calculated. Thanks Dr. Tyson for explaining this!
