      I have confidence in NASA and the research they are doing. I'm old enough to own a book that I received for Christmas as a child that stated "Cygnus X-1 may be our best candidate for a black hole." Now, we know it is and J2150 is the best candidate for an intermediate mass black hole. I can wait.

    @mikecameron7875 4 года назад

    At 3:30 he talks about the sizes of the black holes... Specifically would that mean the size of the event horizon vs the size of the black hole itself? I was always taught black holes occupied essentially a 0 point in spacetime occupied by the full mass of the black hole. The 'size' corresponds to the diameter of gravitational field where the escape velocity exceeds the speed of light.

    • @mikecameron7875
      @mikecameron7875 4 года назад

      Or at least is that what the math says? Obviously we can't prove observantionally what happens beyond the event horizon. Light cones and whatnot.

    • @LaunchPadAstronomy
      @LaunchPadAstronomy  4 года назад +1

      That is correct. The singularity can be thought of as "zero volume" with the mathematical "surface" defined by the Schwarzschild radius, aka "event horizon".

    Also worth noting that a lot of Intermediate Mass Black Hole candidates relative to the number known appear to be outside the galaxy's core which simulations show is not an uncommon outcome in simulated dwarf galaxy mergers where IMBH's are allowed to form via direct collapse instead a lot of them end up wandering in the galactic halo likely to never encounter a star for billions of years. IMBH's immediate environments appear to be too sparsely populated for their small cross sectional area to lead to appreciable interactions. If direct collapse black holes exist it is likely that galaxies of the mass range of 10^11 Msun like the Triangulum galaxy and LMC likely have at least 1 IMBH while a large galaxy like the Milky Way should have a few dozen probably wandering the galactic halo but the odds of seeing any of those is low since if they interact with matter they will lose angular momentum and fall towards the galactic core. A consequence of this is that IMBH's in the local universe are disproportionately to be isolated outside the galactic core as otherwise they would be a part of the SMBH of the galaxy. Of course models are just that models but recent observations have been adding to the weight of IMBH's within the galactic halos or disks of galaxies.

    Recently glanced at Polaris wikipedia page, and there I saw distance measurements vary from 330 ly to 520 ly.
    Given such a great difference, and the fact this is the kind of star we use to estimate distances, I take any distance or mass "measurements" as an educated guess.
    Really scientists should be more humble throwing numbers like 50000 solar masses that are 800 million ly away when they can't get accurate distance that is 10000 closer than that.

    • @LaunchPadAstronomy
      @LaunchPadAstronomy  4 года назад +2

      Actually you'll find that researchers take great care to publish the uncertainties in their measurements. In fact, you'll see the error bars in the graphs I plotted in the video which came straight from Lin et al 2018 and 2020. But your point is taken. When I'm discussing the results, I often just cite the middle number to keep the narrative flowing. However, check out the papers from Lin et al, which are both linked in the description!
