Things You Thought You Knew - Bada Bing! with Neil deGrasse Tyson

[@cathytice6370]

I am so thrilled! I just found this this morning.... I've spent 12 hours watching! I subscribed! Dr. DeGrasse- Tyson; you've been an inspiration to me for years! This show and your co- host are entertaining, informative, creating a craving for more, more, more knowledge and learning! I thank you so much for this! I had to add a comment on this particular episode; remember, 'Quantum Leap'? Way back in the day when it aired, someone was thinking about the randomness of time- space travel. It was mentioned several times by Al that Doctor Beckett was set to a specific time range and within the physical places he'd been before he jumped the first time. The entire premise was based on figuring out plotting the four coordinates needed to bring him back to where he began. I know that a lot of the series was relatively frivolous, but it did address isolation, space- time travel, moral end ethical considerations, what else might be out there. I always think about the last episode. I don't think he died in the conventional sense. I like to think he moved on to other dimensions. Anyway, thank you for this series, and for the provocative content! Thank you for doing what you do!

[@hennedeclan]

I am most likely speaking for my self if not a very small percentage of people here, but I REALLY WANT TO SEE MORE VIDEOS LIKE THIS! I love simply being able to listen to someone explain a complex topic/ subject and only have one person asking questions. For me personally, listening to more than two people speaking in a podcast makes it extremely hard to follow along. This is by far on my list of top 5 videos/ episodes to listen to or watch. I really hope this format continues in the future.

[@jacobharris5894]

@@andye5724 The time dilation is actually extremely accurate because the physicist Kip Thorn worked on making the relativity calculations work out to what Christopher Nolan wanted for the movie. The only thing that might be implausible about it is how fast the black hole rotates to make the time dilation so extreme but that is a small concern compared to making sure the physics works. The movie itself is extremely scientifically accurate in general, excluding the 5th dimension thing which we can’t confirm or deny under our current knowledge and is strictly science fiction. The most egregious things I know of are the blight and the ice clouds but otherwise I think most things in the movie are plausible. It nails the space side of things so that’s why it’s my favorite space movie to date.

I'd seen _Slaughterhouse Five_ as a kid, but had a heck of a time finding it to purchase as an adult. He would open a door at one point of his life and be coming out a door at another; sometimes remembering what was about to happen, but not being able to change it more than incidentally. It did like a lot of things in the movie better than the book, but one thing the book had was that when they came out of the bomb shelter Dresden was totally destroyed like a lunar scape with no other survivors. But in the movie it was just another bombing, with people using hoses to put out building fires. One of the reference books cited in the book, _The Bombing of Dresden_ was said to be anti-American, anti-British propaganda to make the death toll higher than it was.

Therefore, we are simply seeing "old light" from a long dead star.

The Delorean is actually a portal device, which is why it disappears. The amazing epiphany that Doc Brown had when he hit his head wasn't simply how to time travel, it was how to make time travel "possible". As mentioned at the beginning of this video, you don't usually need to give someone a height coordinate, because it can be assumed that you mean "the surface of the earth", likewise the Delorean also assumes the same thing and calculates where you would need to be to end up at relatively the same geographical location on earth.

Here’s something to think about for all clever people out there... and to Dr Tyson if he sees this. In the “Time travel in Back to the Future} segment, Dr Tyson says that Marty should have planned to land not only at the same place but also at the same day time of the year so he doesn’t land in the wrong place of the earth, or even in vacuum of space, as the earth is moving around the sun. HOWEVER, he forgot that the whole solar system moves throughout the galaxy, and the galaxy throughout the universe, so WE WERE NEVER AND WILL EVER BE AGAIN AT THE SAME PLACE IN SPACE. So for time travel to work, we will have to calculate the speed and trajectory of not only our planet, but also our solar system and galaxy throughout the universe, and calculate where we were (if you travel to the past) or will be (traveling to the future) in SPACE at that time. Time travel just got a bit more complicated :) I would love to hear your comments

Love the show. I saw those lines portrayed in sci-fi, actually made me understand it (thanks). It’s in Star Trek: enterprise. The temporal episode when the crewman shows captain archer how time travellers monitor the timeline in his quarters with his device. I think there are a couple other instances. Oh and good point about how time travel without space travel wouldn’t work as you would end up in the same coordinates. Which means going on the anniversary of the earth rotation wouldn’t work either. Actually only travelling through time will make you end up in the vacuum of space and die a horrible death 100% of the time. The reason being that everything is in motion, not just the earth around the sun. The sun itself is rotating around the galactic centre. Our galaxy is moving through space as well, etc. Etc. Better be good at calculating and taking all those into account when you travel through time as you have to basically teleport very very far away from where you currently are to be in the correct space time location!!🤓

[@EJeremyStern]

8:16 I just thought of this. There will never be the possibility of time travel. Neil’s reason (and I agree) is that the earth is moving and rotating therefore you’d have to go back in space and in time. But this means that you can go back in time by just inputting the date-time coordinates as well as earth space coordinates. But that will still not work because our sun is moving, our galaxy is moving, and the universe itself is expanding! This means that you’d have to input the universe space coordinates instead of just the Earth space coordinates. Then again, how would you know the coordinates since the universe is expanding??

[@aregs11]

Need to address this in order to solve it .. 👍🏾 I think they can get close with quantum computing and the cosmic waves that were there at the Big Bang we should be close to calculating that 🤞🏾 all I’m saying is I need the winning lotto numbers plz

[@thomas8734]

I’m happy Neil talked about the earth’s location for time travel as I have always asked this when someone mentions time travel. However, I take it a step further. If space is expanding, earth would never be in the same location. My thought has always been what if time travel is possible but every time we try it the subject ends in space.

[@josephine79]

This concept Neil explained that if we time traveled, the Earth would likely not be in that position in space at the time you travel to so you would likely end up in the vacuum of space and even if by some small chance the Earth's surface is in that position at that time, you would likely end up in a different part of the world (probably the ocean), is something that never occurred to me when thinking about time travel on the Earth, or any world, and I'm always thinking about things of this nature and watch a lot of Sci-fi. So I was honestly taken back and the mind was blown. And since this concept hasn't been captured when time travel occurs in sci-fi, it appears it has eluded most. Exactly - that would be a problem we would always run into with time travel. We would have to calibrate our time machines to calculate where that exact spot on Earth would be located in space at any given time. And since the future holds unforseen situations it's possible the Earth could be located slightly or completely off course when we travel in the future. We would need to either be in a space suit or a space ship every time we travel to the future and probably every time we time traveled for good measure. 😄 We need to make a space ship time machine like that one Klingon Bird of Prey in Star Trek. 😄

[@norminal8520]

[@James-pl2oy]

The Earth would still retain its orbit around the sun for around 8 minutes after the Sun was “plucked out”? Is that really how the gravitational forces work? I would’ve thought that Earth would immediately lose its orbit. Kind of like how you let go of a yo-yo after spinning it around on its end

Nothing happens immediately as you think. If in your example you let go of a yo-yo, it takes time for tension to disappear at the other end of the string which is communicated between individual molecular bonds of the string. The fastest possible speed information can travel is speed of light.

[@FelixEnder]

well the yo-yo spinning around also needs the (string length / speed of light) seconds to notice you did let go of it. There is no way you can transport information faster then the speed of light.

[@James-pl2oy]

Yeah I see what you guys mean but the way Neil explained it just made it sound like we would still retain orbit for that same amount of time that the “snuffed out” Sun’s light would take to get to us here in Earth before we finally realize it’s not there anymore. Maybe some amount of time we remain in orbit but probably not the full 8 minutes and 20 seconds? I’m just not sure what the correlation between how long we remain in orbit with respect to the distance/light speed it takes to reach us

[@FelixEnder]

Yes this is exactly what would happen. We would retain Orbit until the Light (which is traveling at the speed of light) reaches us. Just like the yo-yo would retain orbit around your hand until the light from the moment you let it go reaches the yo-yo. The thing you have to wrap your mind around is how far away the sun really is.

[@PaulCz-h20]

@@FelixEnder Speed of tension disappearing in the string is actually a lot slower than speed of light. It’s equal to the speed of sound in the string. Sound is a wave traveling through material by spring action between individual atoms and molecules of that material. When tension is applied to a string, molecules spread apart to build certain potential energy between them and when it’s released that potential gets released from one molecule to the next like a spring. That is also how sound travels. But that speed being a lot faster in solid materials than speed of sound in air is still many orders of magnitude slower than speed of light. Gravity disappearing from the Sun not being there anymore travels via gravitational waves which propagate at the same speed as electromagnetic waves or light.

Yes, what happened? Does anyone know?

I'd actually made the connection between time travel and actual coordinates in space and time for nearly two decades. Now I wish I'd written a short story and published it or something to have proof 😂 Neil coming up with my ideas dammit haha

[@montanamike7948]

No you didn't.

[@TestTestGo]

This isn't a new idea, Neil is just bringing it to your attention. I'm sure Neil does do cutting edge research but that's not what he talks about on this channel usually, this is popular science aimed at the general public so many of these ideas have been around for at least 100 years or so. That's not to devalue the ideas, if it was thought true then and we still think it's true now then they are probably good ideas, and are certainly interesting if you've not heard them before.

[@zinaright]

At the beginning of this show a few yrs back, I really struggled with the Chuck personna as I thought it was dumb. Now I grew up a little, and this is a brilliant idea.

Mr. Tyson and Mr. Nice are a dynamic duo of sorts. The most fascinating offering that I have seen from Mr. Tyson is his decision to recognize GZA from WuTang Clan as a bonafide pop culture icon who masterfully references scientific terms, and astro-physical processes within the rap lyrics and concepts that he writes. That is how I came to know the work of Mr. Neil DeGrasse Tyson...through the work of the GZA! It goes without saying, Chuck Nice' humour and insight is an invaluable element of the STARTALK experience.

[@stevehillestad1982]

1843, I love you guys. Please keep your show going. Mr. deGrasse Tyson , you’re the greatest scientist/astrophysicist - teacher ever. Thank you to both of you 👍👍

That moon in the horizon bit was so interesting . So we all just collectively psychologically perceive this thing at the same.. distance? At the same point on the horizon? INSANE. Collective.. belief? Perception? Is INSANE.

Regarding the world lines - this concept was depicted in Stephen King's time travel novel, 11/22/63. There was a character portrayed called "The Yellow Card Man" who along with his colleagues was responsible for keeping track of all the time lines that were created by time travelers creating different divergences of time. The yellow card man was able to see the original time line and also the variations that were created. The yellow card man was responsible for making sure that no one created time paradoxes - which always happened anytime anyone traveled back in time.

Neil. You should be brought on to a production company and be part of the physics and theory behind it. For example: an interstellar type of movie
