    I have a low level to no knowledge of astrophysics and all things scientific - however I continue to listen to hours of Neil de Grasse-Tyson’s presentations and love it - each episode makes this 'science dummy' feel like I know something - my working knowledge is growing. Thank you ever so much Neil and your team. I love Chuck - he earths the programme with his highly intelligent wit and humour.

    I'll speak up for ya Neil. While I don't know the "helicopter experts" of whom you refer, I can recount my experiences as a combat heavy lift helicopter aircrewperson, and confirm your original statement. As a general rule, helicopters "fall like rocks" (in contrast to airplanes) when they lose all engine power. As for auto-rotation, it works better on some helos, than others...but, it ONLY works IF you have sufficient altitude in which to create the necessary amount of lift before hitting the ground. Since the majority of rotary accidents occur immediately after take-off, or prior to landing, this technique is 100% useless (my VA disability rating verifies this) because there is not enough time to induce the air pillow. Yet in my aircraft, for instance, auto-rotation is still subject to elevation(atmospheric density), wind, humidity, gross weight; and if any of those conditions exceed a threshold when the power loss occurs, altitude be damned, it's going to leave a mark! When the main rotor(s) lose power they DO NOT produce enough lift to keep the helo in the air, it's the reason for having powerplants (engines) in the first place! They dont propel the helo through the air, they turn a shaft which, through transmission gearboxes, turn the main(s) & tail. Carry on...

      Yup, I concur. After watching this video, I did something I had never tried before. Took a chopper high up in the sky and deliberately cut the engine. It fell straight down and crashed. I wasn't able to control it at all.
      With airplanes, on the other hand, I have lots of experience landing them despite engine failure and other catastrophes.
      (Full disclosure: I've never crashed a real airplane or chopper. Never flown one either. My experience, though vast, is limited to MS Flight Simulator.)

I would've liked to have mentioned the key aspect of _ratios_ of antenna length and wave length, as well as advances on antenna miniaturization like fractal antennas (which relates closely to the coiled-antenna design). The latter really gets to the heart of why we usually don't even see antennas these days.

    Quick question for anyone who knows:
    If the sun were suddenly plucked out of the solar system, how would that affect our orbit around it? Would we feel the effects BEFORE seeing it?
    In other words...does the speed of light (the universal speed limit, as it's fondly referred to as) also limit gravity? Would we continue the same orbit without the sun for Less Than than 8 minutes? Wouldn't that break the cardinal rule?

      How many forms of (energy?) have no mass?
      Light has been shown to be able to be slowed through a liquid. Can the effects of gravity be tweaked similarly through different substances? Er, if there were liquid on the moon, would the gravity of the sun warp around the earth to pull it harder than the earth alone? Does the sun bulge the ocean more wherever there is a solar eclipse?

      @@St1ckY72 Gravity works in a very different way light does. Gravity is the emergent entity when something with mass takes an area in spacetime.
      In E=mc² c=the speed of light so I wouldn't say it has no bearing on it.
      Dark matter/energy, photons, gravity, to name a few. Anything that doesn't interact with the Higgs field as well.
      It doesn't have to be liquid though, if you add mass to the moon it'll increase its gravitation pull on the Earth and the Sun's pull on it will also increase.
      During a new moon or full moon the added tug from the Sun due to its position does help to raise the tides. Im sure it'll be the same case during an eclipse.

      What I mean with E=mc² is, with no mass, a photon is incalculable?
      How do I explain what I mean about the moon...I was wondering if the body of one mass 'gets in the way' of the gravity that should be affecting another. I know it will inevitably, but to what extent.
      If... (With fake numbers inserted here because I don't know the proportions off the top of my head) 10 gravity pulls on earth from the sun, and 1.5 gravity is pulling from the moon, I'm looking at when the moon crosses in front of the sun. Does the combined pull equal 11.5 gravity, or 15 gravity? With that being in mind, is there a discrepancy between the numbers, such as 11.4, or 14.995? Something that would indicate the effect isn't perfectly multiplicative, of additive.

This is definately true for light and the other wavelinks of energy the Sun emits, but what about the loss of the gravity field the Sun also causes? Would the Planet immediately jolt outbound from it's current orbit? Or would we continue in the same Orbit for that same eight and a half minutes?

      What would determine tempo?
      I could waste everyone's time by continuing, but it is easier to state that there are so many variables to consider. Where do we start so to speak. lol
      We can and have directly rendered emitted radio waves into sound. Such as with planets and even distant stars. Of all I have heard, a pulsating neutron star sets more of a tempo than radio wave sounds from our sun.
      All I do know for certain is, I surely will not be the creator of said algorithm. lol

    Hey Neil I have 2 questions for you:
    1. Can you make an object like a ball that is not microscopic rotate up and sideways at the same way
    2. Can you get rid of a black hole by surrounding it with large amounts of gravity to pull it apart

    • @yourguard4
      @yourguard4 3 ปีที่แล้ว

      1. I could imagine, that you can have a ball with extremly precession moving. But I'm not sure, if that can be perfectly "sideways".
      2. You can deform the event horizon of a black hole, so that it is not perfectly spherical anymore.
      For example, when you bring two black holes close two each other, the gravition in the space between them is kinda cancelling out. The radius of the event horizon in this direction would decrease to some degree, but it would never get so small, that you could reach the center of a black hole or rip anything of of it.

    Fun fact: emergent behavior of flocks was actually studied by Dr. Kennedy and Dr. Eberhart out of Purdue in the 1990s, where they invented an evolutionary algorithm called particle swarm optimization (PSO) by modeling behavior. There's a whole field in computational intelligence that continues to study this, but due to the emergence of deep learning, it's not as popular anymore.

  • @ichbins9306

    Neil said (in other Star Talk episodes), that he likes the idea, that dark matter is acutally extra-dimentional matter spilling it's gravity into our dimention. In this episode he thinks about interacting with it somehow. Wouldn't that mean, interacting with the objects in other dimentions which would seem like magic over there? Or the other way around: maybe people experiencing poltergeist phenomenon on earth aren't really turning insane but just witnessed someone from another dimention interacting with their dark matter ..

    • @harvey66616
      @harvey66616 3 ปีที่แล้ว

      I expect that "interaction" could occur only if dark matter turned out to be a particle in our own universe. It's probably mutually exclusive with the "leaky gravity" hypothesis.
      I feel like the strongest argument against "leaky gravity" is that it presumes another universe overlaid on ours. Well, if there's one, why not many? And if many, why not some enormous number? And if some enormous number, then why isn't there effectively an infinite amount of gravity leaking into our universe?
      Granted, a possibly counter-argument to that line of reasoning is that some other effect limits the leaking, e.g. as by a converging infinite series that applies to the leakiness.
      I fear I will not live long enough to hear what science eventually says about all this, but I do hope I do! Of many intriguing mysteries left to explain, it's one of the greatest IMHO!

    The idea of emergence presented in regards to dark matter... If you study a single magnetic object, you may never realize it had the property of magnetism. Only in emergence of multiple magnetic objects and non-magnetic objects could you realize that matter could repel, attract, or have no influence over other matter in this way. There is precedent in existing knowledge that there can be matter that attracts or repels, or does not attract or repel other matter depending on circumstances/object properties. A fascinating thought experiment to think of dark matter in this way.

    • @samsonau8205

      I use a sports analogy when I discuss the concept of emergence with non-scientific people. Bottom line is that you need a minimum number of something (players) to get a game going. When it comes to "existence", you need groups of things to have a significant effect on reality...hundreds, thousands, millions, billions, trillions, moles, or gajillions of particles to impact something.

    As I understand it.
    Time is what actually pulls you towards mass. that describes it's physical function as a dimension.
    If you remove the other dimensions. You still get the same outcome? Because since everything resides in space and the fabric is being pulled towards some mass you will be pulled towards that mass even if you're not moving. So no length width or height dimensions just time.

    If time only moves outward,almost asif repelling its self could it be a logical theory dark energy or matter could be related to or even particals of time since they repell matter and it doesnt interact with anything known and one of the only things i could think of that interacts with nothing but affects almost everything would be time.
    Love star talk its one of the few intellectual shows that draws me in and makes me think. Much love ❤
    P.S. it could still work with the theory of it spilling from an alternate universe, it would just be time maybe cause it keeps expanding at somepoint the universes meet in a sense and time spills out as it continues to expand

    Neil made a mistake on the question about car antennas. FM frequencies hasn't changed. what has changed is that repeaters are much more common especially in urban areas and transmit power has gone up. As a result you can get away with smaller, less efficient antennas that pick up less signal and still get a clear radio signal. Additionally, electronics have gotten much smaller and cheaper, meaning it is easier to amplify the signal picked up by the antenna, which allows for further smaller antennas, like the "shark fin" design
