    Since energy cannot be destroyed, only transformed, some argue that information - arguably a form of energy - cannot be destroyed either. So then, what happens to information when it is absorbed into a black hole? Scientists don't know for certain, but some posit that it may be possible for it to leak away from the black hole over time. Black holes may hold information in a two-dimensional manner similar to a hologram, which take on three dimensions when light is shone through them. Some theorize that the underlying nature of reality can be glimpsed through black holes - that all the information about the entire universe is somehow held on a two-dimensional space of something.
    To better understand how black holes work, as well as the elements surrounding them, we may need a level of physics to be developed.

    MICHELLE THALLER:
    Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory's (JPL) Spitzer Space Telescope. After a hugely successful mission, she moved on to NASA's Goddard Space Flight Center (GSFC), in the Washington D.C. area. In her off-hours often puts on about 30lbs of Elizabethan garb and performs intricate Renaissance dances. For more information, visit

    TRANSCRIPT:
    MICHELLE THALLER: Black holes really are kind of getting to the very heart of our physics. And I believe that they're kind of showing us the way that eventually we're going to need different physics and new physics. People ask questions like, "What happens inside a black hole?" Or even, "What happens at the very boundary of a black hole, the event horizon, when light is absorbed?" And honestly, our physics is telling us a lot of contradictory things. And our image of what an event horizon really is may be changing. People like Stephen Hawking and Leonard Susskind have recently come up with this idea that a black hole should not be able to destroy information. O.K., what do we mean by information? Information can be almost anything.
    All of the different atoms in my body have angular momentum, they have charge, they have mass. There's all sorts of little bits of information that make me me. At the quantum mechanic level, the tiniest of levels, there are different amounts of energy, there are different probabilities that are contained in the structure of my matter. And information, in some ways is a form of energy. It's actually a way that you can describe something which is somehow, in a strange way, a higher energy state than not being able to describe something. And so one of the questions is, "If energy really can't be destroyed energy itself is something that is intrinsic in the universe, you can't really created or destroy it is it possible that information is the same way? Is there really no way to actually destroy the information about what all of my subatomic particles are doing right now?"
    So black holes kind of stare you right in the face. What a black hole supposedly does is it absorbs everything. Space and time bend into a black hole so that nothing can escape. That means that any information about the material that fell in is gone. The only thing we know about it is that as a black hole absorbs material, it gets more massive. It actually adds that mass to the mass of the black hole. And as that mass increases, the event horizon becomes larger. Basically, the area where space is so curved that you can't get out begins to extend the more massive a black hole is. The most massive black holes we know of in the universe are many billions of times the mass of our sun. And the physical extent of this event horizon is about the size of our solar system, maybe like out to the planet Pluto.
    So is it possible, then, if everything goes into a black hole and nothing ever comes out, space and time go inside the black hole and don't come out? What happened to that information? And this has begun to make a lot of people wonder if we really have thought of black holes the wrong way. Maybe there isn't an event horizon in the true sense. I actually had a friend of mine that studies black holes say, "Well, I'm not sure if they're black. They m...

It’s no coincidence that the greatest scientists in history were philosophers and metaphysicians first and foremost, making them much more open minded to the possibilities; which is why they were able to make the counter-intuitive discoveries that they did.

      She lost me when she stated that the event horizon may be a shell with information about what's in the black hole. Only for an outside observer does time appear to "stop" for an object crossing the event horizon. For that object, time proceeds normally and they become spaghettified as they continue toward the singularity. Nothing actually stops at the boundary.

    • @brettfisher5122
      @brettfisher5122 5 лет назад +3

      @@MikeKayK You are both correct and incorrect though. PBS Spacetime showed a good way to visualize the effects of time dilation as every fundamental particle is a marble in a box (no air). An "event" can occur every time the marble bounces off of a side of the box (marble traveling at C). In normal space this is happening like crazy, but as the box is gravitationally accelerated towards the speed of light, the time for that marble to reach the side of the box grows and grows. The box experiencing this acceleration thinks everything is fine because it measures time and experiences reality using these marble collisions. Were the box to observe the universe around it, it would see thousands then millions then trillions then decillions of years flashing by in seconds.
      The box would make it to the singularity, but the marble would be very nearly stuck, unmoving (with reference to the box).

    I always understood the hologram principle as a 4-dimensional hypersphere projecting onto the 3-dimensional universe we experience (or 5-dimensional on our 4-dimensional space-time). Particles, and the quantum fluctuations that either consist of or create those particles of matter along with energy in the form of light, are a projection from a higher dimension. The projection, literally and physically, is physical matter and energy in the 4-dimensional plane of space-time.
    A black hole may display all information that it obtains in the event horizon as a mostly-flat surface (it's the diameter of the sphere, not the volume, but not the diameter of a circle aka a 2-dimensional shape). This would make the dimensionality (if that's even a word) of the information of a black hole the same dimensionality as the surrounding universe, at any given point in time. The only reason the holographic principle describes a higher dimension (5 dimensions) is because, just like a hologram is a recording, it is ultimately outside the boundaries of space-time and in fact contains all of it. The duration of the universe (if that's even a thing, maybe it doesn't end) is fully known and described because all information is accounted for, just like we know all the contents of a recorded video that we've already seen.
    It makes sense to me at least, not that I fully agree with it. The holographic principle supposes that the universe, as a whole (meaning over it's entire duration) is an expression of sorts, leading to something. And that's extremely appealing: that the universe is not only heading somewhere, but ultimately has a purpose, even if we don't understand it, or possibly can't ever understand it. It means there may be higher-dimensional beings that may exist, thus a goal for us to strive towards (growing beyond matter and energy and time, real sci-fi stuff), and a greater form of existence than we could ever imagine, since even our imaginations are buried in the confines of our "holographic" existence, meaning in space-time, and matter/energy.

    Hi Michelle, Another great video making physics understandable to the layman such as myself. I have two questions:
    1) If entanglement of neutrons is a proven theory, would it not follow that by sending one side of the pair of entangled neutrons into the event horizon, or even the black hole itself, that the changes that neutron would suffer would immediately reflect on the neutron that wasn't sent into the horizon and/or black hole?
    2)Would this not be a viable manner of measurement of what happens within a blackhole or is that information lost and therefore the neutrons become unentangled?

      @@panaccoman I'm not sure if you'll accept a section from wiki's Supermassive Black Hole (SMBH) but here:
      " In addition, the tidal forces in the vicinity of the event horizon are significantly weaker for supermassive black holes. The tidal force on a body at the event horizon is likewise inversely proportional to the square of the mass:[10] a person on the surface of the Earth and one at the event horizon of a 10 million M☉ black hole experience about the same tidal force between their head and feet. Unlike with stellar mass black holes, one would not experience significant tidal force until very deep into the black hole.[11]"
      According to this, since Sagit. A is a SMBH "one would not experience significant tidal force until very deep into the black hole", so could it be that the 11 stars were 3 light years far enough from the event horizon that they were not affected by the tidal force and still formed despite being in a non-ideal environment?

      @joops110 5 лет назад

      @@BygoneT I don't know for sure, it's just my philosophy. As long as science hasn't solved the hard problem of consciousness we are free to philosophize. I'll try to explain what I mean as best as I can.
      Imagine the universe is like an online game server and consciousness is the client. Not literally, just to make a comparison.
      The server contains and processes the information, bits in a timeless spaceless matterless but beautiful piece of 'code'.
      Consciousness reads some of these bits, the ones that are relevant to its survival, and turns them into a comprehendable experience. Time, space, matter, colour, sound, motion, etc, are all concepts that only exist within the experience of the client i.e. consciousness.
      You could say the universe existed before consciousness did, but I say time itself does not exist without consciousness. Time is just one of the things we experience to make sense of the 'code' that is relevant to our survival. The same goes for individualism, we experience our bodies and minds to be seperate entities from one another, while we are all parts of one tightly knit 'code'. Some people call this "collective consciousness".
      This is all completely hypothetical and if science proves me wrong I'll change my philosophy. I'm not the only one who thinks like this though, if you're interested I suggest searching for some David Chalmer videos. He looks at things in a similar way and explains it much better than I do.
      Hope this makes sense! :D
      Edit: The reason why I consider this view is because, in my opinion, it's the most complete hypothesis I have found so far. It encompasses everthing.
      How would we ever know this is the case? I don't know. Because it revolves around consciousness it's impossible to provide evidence. We can't check what reality looks like outside of the human experience.
      I hope neurologists and physicists will find a way to explain it in the future, but maybe they never will.

    There is something wrong or not complete about how Hawking Radiation is described in popular science. If black hole evaporate by spawning particles (at the edge of event horizont), it has to spawn both matter and antimatter. If matter is released, than antimatter remains inside (possibly annihilates with existing matter). But it should with equal probability release antimatter, leaving matter for itself - growing bigger.
    So in the end shouldn't it remain the same?

We have only observed blackholes but we do don't know why they are formed. That's why we don't know what is inside them (we don't even know if they have an inside since time stops working). The only logical explanation is that if time, and the 3 spatial dimensions stop interacting with each other like they are supposed to, it creates an anomaly. That's the definition of big in code.

Fortunately, the Universe is enormous and none of its known black holes are close enough to pose any danger to Earth.
      Stellar-mass black holes form from the most massive stars when their lives end in supernova explosions. The Milky Way galaxy contains some 100 billion stars. Roughly one out of every thousand stars that form is massive enough to become a black hole. Therefore, our galaxy must harbor some 100 million stellar-mass black holes. Most of these are invisible to us, and only about a dozen have been identified. The nearest one is some 1,600 light years from Earth. In the region of the Universe visible from Earth, there are perhaps 100 billion galaxies. Each one has about 100 million stellar-mass black holes. And somewhere out there, a new stellar-mass black hole is born in a supernova every second.
      Supermassive black holes are a million to a billion times more massive than our Sun and are found in the centers of galaxies. Most galaxies, and maybe all of them, harbor such a black hole. So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand light years away.

Let's say on average each star holds 5 planets around them. So that means 5000 planets and then POTENTIALLY a blackhole. When a star dies, it may not even become a blackhole. And the super massive black holes aren't at the heart of every galaxy out there. Only spiral galaxies have super massive black holes at their center. So you are clearly in the wrong here. We would be perfectly fine without blackholes. Planets would still be planets, stars would still be stars, solar systems would still be solar systems, and galaxies would still be galaxies.
