Cosmic Queries - The Biggest Ideas in the Universe with Neil deGrasse Tyson & Sean Carroll

[@michaelccopelandsr7120]

I've figured out how to change the stars by stopping hurricanes. Don't worry, I've technically already done the easy part and changed the stars. My parents were teachers and for over 3 decades, they taught their students my constellation. Those kids will teach their kids. So on and so on. See, stars changed. I just need help to make it legit and with the rest. I need to get to Texas ASAP. No, I'm not kidding. Yes, I'm serious. I get 7 things. One of them being to change the stars and remember, crazy is a compliment. Figured Neil has taken on the IAU and won. He's the best place to start. If, rather when, it works it could be converted to a larger scale and EASILY regulate temperature, end drought, stop wildfires in the west. Let me know if you're interested, please and thank you. It'd be wrong of me to not, at least, try. This is me, trying. More, hopefully, to come.

We got kicked out of heaven because of free will. Think about it..

[@louisesumrell6331]

"Mr. Hitchens, do you have free will?" "I have no choice."

[@thelostone6981]

Haha. Anytime I see Sean Carroll’s name, I always think back to the time he debated Bill Lane Craig. It’s one of my favorite debates….except for all the Hitchens debates. Who unfortunately also debated Bill…

[@peakrider4886]

Where is this quote from? I’d like to read up on it. My own personal theory is that free will is something we think we have but within the boundaries that everything that has happened in the past was always going to happen, and everything that will happen in the future is always going to happen that way. I’ve learned there are plausible scientific concepts which say our lives are a story book and the past is the book we’ve already read, and the future is the part we are yet to read through, but it has already been written and has chapters and an ending.

[@scottcarr8738]

Right? In its original form I spread this across my friends. More than once for that matter!

[@andypeiffer5]

Was just thinking it would be nice to have these questions time stamped and then BOOM there they were in the description. Thanks!

[@alanhehe4508]

Very interesting discussion, and I love that you all still have a good sense of humor.

[@MichaelSmith420fu]

My modern perspective on the question "do I (we) have free will?"- First.. you have have to think deep and long about what is "I" or the "self". I think that if one is willing to accept physics and spacetime then they have to admit that everything is just borrowed, re-emulated versions of what came before. I mean look at a kid who is a splitting image of their parent. Their jeans are similar, their perspectives, morals, strength, weaknesses, ability to conceptualize...even things like that.. are all related directly to their nurture,nature,and environment. So if you can accept that, once you start thinking about Free Will and the self and wear this so called Free Will is coming from you can start to get a more realistic understanding of what is going on. Remember like we were joking about.... It's complexity 😋

[@ericvulgate]

I don't think I've tried to talk someone out of their free will. I WILL say that believing we have free will must be very important to our survival for us to cling to it so strongly.

[@frankwestphal8532]

Sean Carroll is now one of my favorite physicists. I love his depth of knowledge and flexibility of thinking. People like him and Brian Greene, appear to me, to be on the cutting edge of human understanding of the universe. And I'm sure I'm missing others that I will soon discover as well. One thing that sometimes bothers me about scientists in general, is a level of arrogance about our understanding of various systems. But we don't know what we don't know, therefore we always need to keep a partially open mind. The more I learn about the universe, the more humble I become relative to it, becasue I can start to see how much I don't know, and that some of the concepts the universe incorporates might not even be grasp-able to my (or even any) human brain at his time. When humans have lived 14 billion years, maybe we'll know it all. Until then, I'm going to be listening, learning, and ever evolving. And as always, thank you to Neil and Startalk co hosts and guests for bringing this great content to us!

[@slimshadyfoeva333]

[@Kandylanekira]

OK I love this! Although, Sean Carroll will continue to go even further if he realizes that he hasn’t learned everything there is to learn. I can tell Neil is always still thinking outside the box like he doesn’t know everything which is why I hear so he is. It’s always super fun watching these so thank you for sharing them with us!

I really love and respect Neil but; don’t mess with Sean (and most of all stop interrupting him), as he is on another level…

[@tom-kz9pb]

When anyone asks whether we have "free will", they should be asked in turn what exactly they even mean by "free will". That we sometimes make decisions free of any *external* influence at the moment? Of course we do. That we sometimes experience momentarily indecision and have internal impulses simultaneously in conflicting directions? Of course we do. That we are somehow "free" of the internal workings of our own brains as we make a decision? Of course we are not. So the bottom line answer is, "No, we do not have 'free will'. It is a sentimental illusion surrounding a fuzzy, poorly defined concept."

[@noahyes]

[@slocoast5]

My favorite Theoretical Physicist 🧑‍🔬 Mr. Sean Carroll 🤩🥳 and Mind Scape is his channel

[@JoyousMelancholy]

just a question. If in the vacuum of space once you start moving in any direction you will not have anything to slow you down, thus you go on forever without stopping unless you hit something (like a planet or star) because your momentum does not slow. so why is it that reaching lightspeed through "speedcreep" where we accelerate then shut off the thrusters. our momentum at that acceleration would become our new base line , thus if we then power up the thrusters again and accelerate from our new base momentum, rinse repeat. the real issue with high speed travel in space is how to controllably stop because it will take far more energy to stop then to creep up to full speed. is this accurate or am I misunderstanding something?

[@nickbisson8243]

Look up the rocket equation. You'd need a gigantic rocket to start plus you'd need to carry enough fuel to eventually slow you down. More fuel = more weight. More weight means you need to add more engines which again adds more weight which needs more fuel.....which is more weight. It's a revolving door lol

[@JoyousMelancholy]

@@nickbisson8243 why would weight matter in space where there is no gravity to create weight from the object's (in this case the ship) mass. if we were talking about in atmosphere, your right. the rocket equation would help but not for this scenario. once in space and "fair enough away " from the earth to be effectively outside its gravity, weight is nothing more then what you get from going to close to a planet or near a star. in my question I specified we start in the vacuum of space. once in space the "weight" of said fuel means nothing. so to reiterate (this time using numbers to help get the idea) when in space why wouldn't thruster cycling lead to incrementally faster and faster speeds? like if we have (just using simple numbers don't read into it) a 100kg drone with a thruster set that produces 147.1N's of force in the same direction and we cycle it ten times in space once we start with momentum we don't stop with out effort(IE: reverse thrusters) thus would cycling the engine not be the same performance wise to having had a thruster set capable of 1471.0 N's from the start? Sorry if this is doesn't make sense, writing is not my forte.

[@feedingravens]

Just came to my mind recently, like there is matter and energy, and gravity makes matter attract each other, maybe Dark Energy (that quasi pushes matter apart large-scale) is simply Anti-Gravity, that separated from Gravity some time after the Big Bang. Not that I know a lot concrete about physics, but who knows?

[@Sin_Of_Greed]

Tes, it has been theorized. It's actually some what likely, as my personal hypothesis, that Big Bang created such a large force, that I pulled the Universe apart so greatly it's ripping it apart, leaving behind Dark Matter. Or another way of putting it, it's possible that, that's the way another universe is showing it's face to us.

[@abeautifuldayful]

@@Sin_Of_Greed ...or if not its face, then maybe its cosmic farting rear?

[@skylark8828]

Or the quantum effects within spacetime itself create what we call dark energy Spacetime is pulling itself apart. There's also something called inflation which started the Big Bang.

[@jourdansarpy4935]

Complex is a description of the system and the amount of parts and connections it has. Complicated is about how difficult it is to live with the truth of the system. A complex relationship is one with a lot of different pieces that interact. A complicated relationship is like the one I have with sugar. It’s just me and sugar, but it’s hard to live with the fact that I love something so much that it’s not always good for me.

[@Salsadans123]

It is very interesting to see these kind of discussion and I have read a couple of books of Sean to. Sometimes I wonder where is their drive comes from to understand things. It could be to enhance our lives, but the more you know the more you understand that the universe do not care for us and that there is no reason for life in general. So for me it is interesting to know why we want to understand these things instead of find way’s to give life a meaning and make things better.

[@walternullifidian]

How many of what we call "constants" aren't really constant at all? For example, I just recently learned that the fine structure constant has been decreasing since the big bang.

[@skylark8828]

It depends on "when" after the Big Bang, as the electromagnetic was supposed to have merged with the other forces ie. weak and strong nuclear forces moments after the Big Bang. It hasn't changed since that happened.

Free will is much more than just a choice, it’s a metaphysical ability. Free will is the brain’s ability to focus or not to focus. Philosophers have answered the question years ago, most scientists have yet to catch up.

[@dwayne_dibley]

You were always destined to make that comment. If choices are not determined, they are random as anything that isn’t randomflects some underlying disposition or necessity that determines it.

[@randywayne3910]

@@dwayne_dibley the underlying disposition is a natural ability of the human brain - focus. The ability to focus, or not to focus, results in a concept we call free will. Claiming we are mentally determined, is to claim we can both focus, and not focus at the same time, on the same idea. Are you focusing on refuting my comment, or not refuting it? You cannot be both. Like infinity, random is an abstract concept, it does not exist.

[@tarmstrong9906]

Best answer yet, by Sean, on free will.

[@alexhigginbotham8635]

I would say that to a degree we all exist (if you can call it that) within a set of parameters... albeit broad ones. Some might call it a simulation. Therefore we have 'free will'... within said parameters.

[@dennisestenson7820]

27:40 that is a great way to describe free will accurately.

[@TragoudistrosMPH]

12:55 That's an intriguing concept. How odd that there is the possibility of a world we couldn't eventually understand with enough time and resources.

[@nickns732]

If we can’t change the past, and everything happening now is determined by the past, then we have no free will. Your decisions now will always be framed from past events and experiences.

[@danzactivaballaja6083]

Great and enjoyable. Thanks.

[@ryanrutledge922]

Thank u for teaching me about Sean's mindscape show . ❤ U Neil

[@marchalthomas6591]

On free will, each choice seems to be the result of an evaluation. Two options are weighted, but with our own metrics. Those metrics depend on our past experiences and our character, also build by our past. It seems very mechanical and predetermined. Sure we have will, like trying to explain my point of view or accepting it as valid. But nothing shows that it constitutes free will. Free will seems like you could go against all odds and do what you will not do, which is never happening by definition. And if by chance there was a brain circuit that gives random output, there again, it would be random will, and not free will. So even if you wake up one day and decide to do a parachute jump for the first time, it is the result of your life's experience, not a free choice.

[@JM-us3fr]

If anyone is wondering how to do Neil’s calculation at 7:05, 100 halvings gives you 1/(2^100). Using the classic approximation 2^10=10^3, we get the estimate 1/((10^3)^10)=1/(10^30). 29:21 I would just want to push back on Sean a little because I don’t think his point here made sense. If I try persuade you of something, then I must be operating under the assumption that you are _persuade-able_ . That is to say, some of your positions can be determined by persuasion. That is completely consistent with a _lack_ of free will.

@startalk how do we know all the stars we see are stars and not potentially white holes. Would there be an obvious gravitational push surrounding it if one was ever found

[@TheRealJamesKirk]

I went to read up on white holes and ended up at "Lie Groups" on Wiki. I have a general basic barely understood notion of how black holes are predicted by Einstein math, but white holes? Beyond my event horizon. And Lie Groups are up there with Mandelbrot sets. Advanced maths are strange. I think I should go back to the beginning... 1+1=2 etc.

[@psycho6542]

Who the what are you talking about ?

[@ubercoo]

Probabilistic & opportunistic will, might be better description for "free will". As game theory using a chess board as an example. There are a finite amount of moves (choices) within the standard rules of our given world. There are many factors such as awareness, response, emotions etc. If you were a piece on the chess board which has no awareness about how many moves you could make then that may not allow you to move. This is acquired through education & expanded thought to see further across the board. Another concept is a river & a fallen tree. The animal could not cross the river until the tree fell across allowing a bridge to be created. In life, we need more education bridges across problems instead of street signs already designed to keep you running in circles.
