    Thank you Paul!! I'm slowly going through all your TH-cam vids & your Students are so fortunate to have such a charismatic and, frankly, hilarious Professor! I absolutely love Leonard Susskind - I can spend hours listening to his lectures, but you are an awesome educator! I'm 53 now and I've studied Black Holes since I was 9 years old. My parents took me to see the Disney movie The Black Hole in 1979 & I've been hooked since. I loved Computers more though & spent most of my career running the backbone of the internet & Cyber Security but I now work in Health Care, which I find so rewarding it's not true! Still I love Physics, QM & Cosmology - juries still out on String Theory, but I'm not hopeful in 2023!
    I took my daughter to the Jodrell Bank Observatory in Cheshire, UK when she was about 10 years old and they put on a science show which included a really great example of quantum levitation, a liquid nitrogen chilled superconductor & a magnet, you know the one! The kids were sat in the front rows with the parents behind and were captivated. The excellent Presenter, a PHD student, asked the kids "Why they thought the magnet was levitating?" I bent over and whispered in my daughters ear to put her hand up & say "It's because of the Cooper Pairs, it's the Electrons!"
    OMG the look on that PHD's face was a picture!!!

    One part of your explination was confusing/wrong. You say that the observed mass/charge is because we still see the matter outside the black hole. The problem is that the initial contents of the black hole are already inside it at the moment it is created. I.e. it never crosses the event horizen. A simple application of this leads to the conclusion that all of the initial mass/charge just disappers from the universe. This leaves the initial black hole with no mass or charge. I am sure this is wrong. So can you clarify/explain this? Thanks.

      @FzFx 5 ปีที่แล้ว +9

      I thought this problem of the moment of creation of the BH. My thinking: Just before it is enough mass is concentrated in the sphere (of the star), you still can see the mass, even if very distorted by the very distorted spacetime. Then the next moment the BH appears in the place of the sphere, replacing it instantenously. This seems as losing every information suddenly that was the sphere of mass before. But an outside observer sees this because the finite speed of information: From the closes point to the observer, on the surface of a sphere of mass, a tiny BH forms starting from 0 radius, and growing bigger by the speed of light, and enveloping the whole sphere, turning it into a black hole. I have a suspicion that this is still counts as objects (never) falling into the event horizon of the black hole.

    • @carywalker7662
      @carywalker7662 ปีที่แล้ว +2

      You must first understand the relatively simple special relativity. Time is different inside vs outside black hole. From outside, infalling particles never form the black hole because it takes them forever to reach the speed of light. Thus, we always feel and see their effects.
      As an aside, how then did we take a picture of a black hole? The infalling objects red-shifted into blackness and other objects fell in afterwards. We see those.

      @@johnbennett1465 Sure, but that light will not ever reach you; (As that light is in nflowing space at nearly the speed of light, and you are moving away from it in time at the speed of light (time-like direction).) So it will not ever catch up as it cannot exceed "c". You will see this like a still photograph from outside the Event Horizon as the speed of "c" is constant and equal.
      All the effects of Black Hole (gravitational) are likely due to the extreme curvature of the event horizon. It just depends on which side you are on. Time on one side, space on the other. It's not an abrupt transition, but a gradient. You feel the effects from that local gradient, which is continuous from the "singularity" to the outside of the event horizon. Information flows only one way if you're beyond the event horizon, but two ways if you're before it. They still communicate however.
      I would say the magnetic charge we 'feel' is from the accretion disc, not the Black Hole. Relativistic speeds of moving charges make a rather strong magnet. Not all Black Holes have the same charge, so this is not solely a function of having the "singularity"/ interior Black Hole itself. More spin and more material in the disc, the higher the magnetic field. Not every B.H. is a quasar, for example. It's the disc that provides this charge. And the disc is on "our" side of the Event Horizon.

These EM refractions have left-handed rotations. This is opposed to the natural materials that lose energy after reflection. This has a potential, at the quantum level, for a new source of energy.

    What science will eventually discover is this: There IS no "inside" of a black hole. Black holes have 2 "outsides," the one we see and the one we don't. The side we don't see is the other "outside" that could only be seen from the other universe to which that other outside belongs.
    Each "side" of a black hole is a gateway to a completely different universe. Isn't existence strange?

    When particles and waves are spinning at angular momentum and centrifugal forces accelerate them to the speed of light, the center of the black hole turns matter and energy into pure gravity. Yes, physicists are correct: "Not even light can escape a black hole." That's because the gravity is so strong that it literally smashes (fuses) photons together and won't let them escape. Once the photons are fused together, the radiation has nowhere else to go, and you get the "jets" of material which come out of quasars etc... When matter or energy are traveling at the speed of light, they *become* light. So that's what's happening at the center of the black hole. All that exists there are gravity and light.

    I really don’t get why you say that nothing escapes a blackhole, therefore the force of gravity shouldn’t escape either.
    I was under the impression that according to Einstein’s relativity gravity is not a force. It’s just an effect caused by mass altering the geometry of space time. I don’t see the need to use the term “ghost” either. The star that formed the black hole has not “disappeared”. It has collapsed, which means it has become incredibly dense. Still there though, still bending the fabric of spacetime.

      You would see everything sped up. Unlike in special relativity, the situation in general relativity is not symmetric; both observers agree that the clock deeper in the gravitational field is slower. This is a result of gravitational redshift and blueshift; light climbing out of a gravity well loses energy and thus becomes redder, while light falling in gains energy and becomes bluer. Both observers agree on the sign and magnitude of the changes in frequency and thus the rates of the respective clocks.

    Here’s a little something you don’t know. There is no such thing as a field. Time does not exist in the three dimensional universe it is only a measure of perceived movement. Gravity and magnetism are not forces, those are attributes of a single source of energy that exists as a result of movement between the 3rd and 4th dimensions.
    If you want to unify things all you need to do is look at the source point of all potential energy. Things pop in and out of it. It creates the attributes of gravity and electromagnetism. On its flip side (4D) is where time exists but space (as you perceive it) does not!

    This could be the answer to the final parsec problem. With a coating of matter forever falling into the event horizon, a nearby black hole would impose tides upon this matter; thus, robbing the angular momentum and allowing the two black holes to eventually merge.

    So, is this the basis for entanglement?
    Instead of a monopole, couldn't particles be more negative or more positive even though they each have two poles, but that would make them act relatively mono to each other?

In his book, "The Black Hole War", Leonard Susskind said this was NOT the case. But that was a few years ago. It seems this topic never went away and is making a comeback. Do you have an opinion on this that you'd be willing to share? Hope all is well.

      To this day we have no experiment that can determine with any degree of certainty that we are not living in a black hole. The ever increasing speed of falling to a singularity and the subsequent red shift that would occur would mimic the increasing expansion of the universe and its red shift. The heat death of runaway expansion or the heat death of time(motion) stopping, would seem the same at this point. I'm not sure what the holographic principle has to say about this, but I'm curious about the direct proportionality of information in a black hole to its event horizon surface area. I think the answer lies there somewhere.

    Just for fun I'd argue that you can create a mono-pole magnetic field by taking a bunch of magnets, forming a sphere with all the positive sides facing inward and all the negative sides facing outward. Now you essentially have a negative sphere, and if you drop a bunch of them in a bucket, they won't ever touch each other, they'll all float except for the first layer resting otttttthe bottom of the bucket. To avoid confusion, it doesn't matter which polarity faces in or out, it could be all the positive sides facing outward, I just had to pick one.
    As for magnetic vs electrical, I'd argue that they're one and the same, it's the observation which differs, like the fixed frequency of a sound or light which doesn't change and yet seems to shift according to changes in distance between the source and observer.

  • @deandeann1541

    I assume that a black hole's mag field is actually the mag field generated by the disk of material orbiting the black hole. The disk is heavily ionized thus many electrons are orbiting the bl hole at near C, of course there will be an intense magnetic field orthogonal to the electric field. I believe Mr. Sutter is giving an alternate description of the same phenomenon. Both descriptions are accurate and describe the same thing. The measured effect will be subject to frame dragging of course.
    With respect to gravity - the gravity itself is what keeps things from escaping the black hole. To state that the intense gravity also prevents the intense gravity from escaping is a self referential paradox. Of course it must escape! As far as the residual mag field or the progenitor star - yes it should be there theoretically (just as a tiny bit of that star's light should be there) but it should be deeply red shifted and nearly nonexistent, the majority of the magnetic field is from a time subsequent to the formation of the bl hole. As far as this goes I disagree with Mr Sutter, the fossil mag field of the star for all intents and purposes will not be detectable. The area just outside of the bl. hole does act as a window into the past due to the effect of the bl hole's gravitation upon space, but it is an exceedingly dim window (the light that may be released in a second by the star may eg be released over an extremely long period of time, assuming it had to crawl up from a region very close to the eh).

  • @1bigdogthe

    1. Black holes become more dense as atoms are crushed this is why they have huge gravitational waves, they don't escape, they pull other matter toward it. 2. No matter how small you cut a magnet it retains a north and south pole, no monopole has been found in the universe. 3. If you call a quantum spin charge magnetism it would make them monopoles, but spins can be altered by collision or transfer (in many ways). This is the only interesting idea as particles with opposing spins do attract each other.

  • @johnorr4971
    @johnorr4971 11 หลายเดือนก่อน

    A Black Hole is not a 'hole' in space or matter at all. The Black Hole is an imaginary descriptor of a phenomenon that is not fully understood but represents a collapsed star whose mass mass exceeds the ability of anything having mass [i.e. affected by gravity] to escape its force and thus takes on the appearance of a hole. Magnetic force is not affected by gravity because it is not an elemental mass force but is rather a parameter of the phenomenon that causes the forces of mass and gravity to be manifest in the first place. When you cross the threshold of theoretical to the actual you are 'crossing' the event horizon and pass from the observable world of signs and wonders into the unknown that can only be perceived intuitively leaving us with ideas that are speculative at best.

    The mystery of magnetism for me is that it also behaves like a fluid, and the Earth is the best example of that and it then surprise, surprise explains how we can know that a Polar Shift has happened on more that one occasion.
    I would disagree with you on what "Black Holes" are and would happily share my theory on them. Whilst I am going to do that I would like to introduce to you what "White Holes" are as they to have their place. Despite not necessarily having been discovered yet.
    So here is my theory on black holes and white holes, and logically they are sound. Imagine you are in a big high street store, and you walk in and you see a lift in one corner and escalators sign posting you to what is on each floor. Now simplistically take that analogy and apply it to the Universe or Multiverse and then what you have is probably a better understanding of both space time 4th Dimensional layering, so imagine in the same way you are holding an onion in the palm of your hand from the outside we see it for the shape that it is, but its not till we cut it in half that we learn how it is formed.
    Space is probably far more convoluted and creatively put together than our Earthy onion I would like to think but it allows us to take a look at space different and it allows us to understand how we can move in these different planes or layers, if you are following my drift.
    So let's say a Black Hole is no more than an escalator that takes you down one level, and a white hole allows you to bring you back up to that level you was at. It then gives credence to how space can be as described in the film "

    How can a black hole 'emanate gravity', you ask?
    Let's say we're allowed to discuss gravity as a force.
    A massive object becomes so dense that its undiminished 'emanated gravity' is concentrated in a small enough space that light attempting to pass it gets trapped.
    Any light that the dense mass might itself be producing, is likewise constrained from escaping its gravity.
    To an observer, its location is, therefor, visibly black.
    What you see (don't see) is due to its 'emanated gravity'.
    Who ever suggested that a black hole would be ingesting its own gravity?
    It's actually pulling so severely that -- not only does it exert an attraction on all matter outside it -- it even gobbles up any light that strays too close, thus earning its name.
