Galaxies Galore with Neil deGrasse Tyson

Ғылым және технология

What does JWST tell us about galaxy formation? Neil deGrasse Tyson and Chuck Nice answer questions about galaxies, measuring the distance of far away objects, dark matter, primordial galaxies, and more!
Thanks to our partners at Ford for sponsoring today's video. To learn more about the all-electric Mustang Mach-E, visit www.ford.com/suvs/mach-e/
How do we determine how far things are from Earth? Learn how stereoscopic vision inspired astrophysicists to discover the distances of far away stars. Learn about Henrietta Leavitt, variable stars, and Hubble’s discovery of the andromeda galaxy. What is parallax? Find out about arcseconds and how Star Wars uses parsec wrong.
Why can we see massive galaxies just after the big bang? We discuss JWST’s primordial galaxies and the definition of dark matter versus dark energy. Why doesn’t dark matter fall into the center of galaxies? How do supermassive black holes get so big? What does this mean for the age of the universe?
We explore redshifting and the nature of the universe’s expansion. What would be necessary technology for aliens to have in order to visit us? Why would aliens be interested in Earth? How has the JWST forever changed our understanding of the universe?
Thanks to our Patrons Will Bailey, Joanie Nelson, Holly Harlin, Terry Eby, Brian Pennington, Dan Dymek, and Alex Florescu for supporting us this week.

    Could it be that what we percieve as an accelerated expansion of the Universe is actually something else like slowing down speed of light? What if speed of light is "constant" only because we can measure it on a relatively small distances but in scales of the Universe it is not constant. It's like Newtonian physics is ok on a small scales but on a bigger scale we must consider Einsteins's relativity.

    I like Dr. Tyson's gold Omega Speedmaster. The Speedmaster is my favorite wristwatch. I still have mine from 1969 that was given to me as a BD gift ten days after Buzz Aldrin wore his as the first wristwatch on the moon. Mine isn't gold but it was built shortly before Buzz wore his on the moon on July 20, 1969. So, it's a pre-lunar landing Omega. It still works well after all these years and looks almost new after using Polywatch to remove any small scratches. Beautiful watch Neil.

    When Hubble looked at the variable star in Andromeda and figured out how far away it was and that existed in a galaxy outside of the Milky Way I wonder if it gave him goose bumps like it does me. A discovery today that might be comparable would be hard evidence of a universe outside of our own, which, of course, there is a lot of speculation about. Back in Hubbles era, I don't know that there was much speculation about our universe being so large to have many galaxies well outside our own.

I didn't get very far in high school science and my college science opportunites were limited to one semester each of geology and astronomy (as online student 20 years ago back in the 28k days ), so please forgive if I'm missing an obvious reference; that said, "ghost" could mean all kinds of things and I'm very interestd on what it means to you if you're being serious.😉

    I once read Fritz Zwicky's 1936 paper where he develops the idea of Dark Matter. In this paper, it is assumed that the Hubble constant is 500 km/Mpc, not the 70 km/Mpc we use today. (And of couse, Fritz Zwicky was not talking about exotic, non baryonic matter as we do today. He just said that this matter apparently is dark, e.g. not found so far by the astronomers which were looking for light sources.)

    @@Espada_S346 There are long form interview videos, but I'm pretty sure Neil just doesn't have the time to do more involved videos. Since 1996, he has been the director of the Hayden Planetarium. I'm not sure what his daily life consists of, but he does occupy positions which require time and thought. I'm sure he puts as much time and effort into the show as he can, but clearly his profession would be the top priority. Joe Rogan's content is one of the lowest effort and unresearched podcasts. The fact checker, Jaime, will be employed forever, because Joe can't stop spreading misinformation. If anyone aims to regularly produce hours long videos, they're not going to do it responsibly, because you can't, there's just not enough time in the day for a professional to produce well researched content in 2hr videos multiple times a week. Be thankful that all the videos posted on this channel are meaningful and teach you something correct about the universe. Even if it doesn't consume every second of your evening entertainment, the videos are actually valuable, because they spend time creating something meaningful.

    I finally saw Andromeda witha cheap monocular that also came with a phone attachment. I tried to navigate my nephew with it the same way, you just have to be very steady with your hand, know where to look, and be in in the country like me and let your eyes adjust for like an hour. After I saw it with the little monocular, I could see it without it. It's just an incredible feeling as a human to look out and up, and see an entire different galaxy full of mysteries all the way from here on little earth. I highly recommend trying to see it, and it's a perfect time of year right now too, it was just after dark and it gets dark early.

    Hey Neil, I still need help with changing the stars. My idea for changing the stars includes Orion and Pleiades (Subaru). I figure it's time to put something up there that's relevant to us, don't you think? Take Orion's belt and Betelgeuse becomes the head with a baseball hat. The 3 stars of Orion's belt make up the 3 fat belt loops on a baseball uniform. Below the belt are two legs bending at the knee. Saiph is the back foot and Rigel is the front foot. The feet aligning perfectly under the bent knees. The spear pointing at "Subaru" is the bat being swung and "Pleiades" is the baseball flying away after being hit. Bellatrix is the hand that let go of the bat. Put it all together and you get, "THE ALL-STAR." In my case, I see a left-handed batter and I imagine a "7" on the jersey. Which makes him, "Mickey." (As it should be ;-) But you can put any number you want, making, "THE ALL-STAR," any player you want. It'd be wrong of me to not, at least, try. This is me, trying. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment. ;-P

In the movie, Solo: A Star Wars Story, Han took a shortcut in the run and decreases his distance. This was all probably done though to rectify the mistake in the first place. Love the show!

So it was the Guidance System on the Mellinium Falcon that made it the fastest ship in the galaxy. With speed being a constant, it's the route and the distance traveled that determines the overall speed of the journey. It's science! PS Great show

    My guess is that dark matter is: Spontaneous matter forming at the quantum level at the same time. Randomly forming in a relatively small area (small for a spatial scale), generating a very strong gravitational force, but for a very short period.

    Dark matter is the biggest cash cow for academia in history. I say we are observing the gravitational effect of the masses of other dimensions on our dimension.

    Dear Dr Tyson and Dr Nice! Given that If, events of early universe was what formed the elementary particles/waves that in turn formed us and our local galaxy, then; How is it that the light of early formed galaxies (i.e moments after the big bang) it's light only reaching us now, but it's effects (the elementary particles) have long cooled and formed into our local galaxy? Could it be that the "effects" of those recently observed most distant galaxies/events, will only reach us in the future, rather than in our past?

    @8:11 -ish what happens if the star moves during the 6-month period you're waiting to measure its distance. How can you get an accurate distance for a star if the star is moving in between snapshots of measurements?

    I have been meaning to join the Patreon just to ask about the Kessel run!!! The Falcon flies at such a speed through hyperspace that it is able to skirt the border where gravity cancels out between black holes. Is such a thing possible?

  • @chrisaraiza6761

    So 12 parsecs is impressive because slower hyperspace vehicles have to take longer (distance wise) routes to evade the gravitational pull of the black hole cluster surrounding Kessel. The premise is a faster vehicle could take a shorter route because it can traverse a path where the black holes are closer together. For more context. Is it possible?

    Please explain to me why I can easily touch fingers every time with just one eye? Could I be divergent? It's actually slightly harder at arms length. Pretty cool , that slight difference made a difference.
