Hypothetical Stars: Exploring the Bizarre Giants That Could Exist in the Universe

Welcome to the mysterious realm of hypothetical stars, the bizarre astronomical objects whose existence has been predicted by physics, but has yet to be confirmed.

  3. Shouldn't the Strange Star send out a solar wind full of strange matter?
    Wouldn't EVERYTHING within the heliosheath be converted to strange matter?
    Wouldn't the heliopause form a "solid" barrier of strange matter?

  6. There’s a few interesting hypothesis as to how civilization could still exist, even around iron stars. Those interested should check out Isaac Arthur’s channel, just be warned he’s not quite as entertaining as Simon.😂

  9. And one day, long after the last Iron Star formed, the last english-speaking Human realised that it wasn’t pronounced Schwarz-child but Schwarz-Shield…
    But then it pulled an Asimov, another few orders of magnitude of years later the Cosmic AC answered The Last Question, and all was well in the Universe.
    (Schwarz Schild. Black Shield.)

  17. There’s also the hypothetical “plank stars” from loop quantum gravity, they remove the black hole singularities, instead provide an upper bound to how dense matter/energy could ever be “plank energy density” …. Incredibly small/dense and very very short lived, though cause of the extreme time dilation from our perspective they take eons upon eons to cease

  20. "Thorne-Zytkow objects, with a spirit of resistance to your current beliefs about frequencies of all types of juicy quicksand, dream of unicorns and lollipops since the temperature is above the Hagedorn temperature. The common denominator is chicken soup for the soul. It used to be called the neurological apparatus of shocking discoveries, with heaps of snow falling from the sky. At least you have a chance to go faster than you think. The proof is in the pudding when you look through deep sea sediment samples finding traces of iconic roadside attractions with ultrashort flashes of light. Singing ice is constantly extending and retracting a spiral-shaped concentration of femto-angstroms. Sound familiar yet? To this day, it still amazes me that there hasn't been much conversation on the color confinement of the Pauli exclusion principle affecting molten ice lava capable of quantum level oscillations. If you build it, they will come. Because, you know, it’s going to work this time. Star Wars would have been so much better if Luke Skywalker had been a penguin. I see dead people."

  27. Scientists may have already discovered a Thorne-Zytkow Object.
    HV 2112 in the Small Magellanic Cloud shows peculiar spectral lines that are the telltale signature of a TZO.
    They admit that other mechanisms may be responsible but it is a very good candidate.

    Neutron stars fascinate me, I wonder what would happen to neutron stars in the far future, would they slowly evaporate and the free neutrons decay back into protons and electrons, would that happen over time even to the neutrons still in the neutron star, would it lose mass through the gravitational and magnetic fields, would it change as it cooled and could its density increase to the point of forming a cold black hole?
    The more I learn, the more questions arise.

  30. You are missing cold helium stars. If a star has enough mass to fuse hydrogen but not enough to fuse helium, it will eventually be made of nearly completely helium. Then, in a quadrillion years or so, it could cool to superconducting temperatures. A quarter solar mass of clear superconducting liquid. 10:42

  31. "Until black holes have evaporated." Seems like a weird thing to think black holes would do. The universe is symmetrical and if the theory that we came from a black hole in another verse is correct; then I'm thinking it's more likely the black holes would consume everything until nothing on our universe was left and so on and so forth

  36. As soon as a star starts creating iron, it only has seconds to live because iron creates zero fusion energy. At that point gravity takes over and the star collapses onto the iron core, the rebound off the core into the onrushing material heading for the core causes a Supernova. Depending on the mass of the star you either end up with a neutron star or a black hole.

  38. The Black Hole at the center of the Milky Way is written Sagittarius A*
    It's pronounced "Sagittarius A-star."
    It's an odd notation that we pronounce an asterisk as star, but there it is.

  40. strange quarks aren't "highly unstable", they last like 100 picoseconds and decay via the weak interaction. Originally, it was believe they should decay strongly, in which case their lifetime would be around 0.00000000001 picoseconds…now that would be highly unstable.

  42. 12:30 And if you wanted to see an iron star die, you'd have to wait much, much longer. Theoretically they then collapse into neutron stars, but that happens on the order of 10^(10^76) years.
