Awesome and engaging video! I don’t have much else to add that wasn’t already said, so I’ll speak to my experience hunting down your videos. I kept forgetting the name of the channel (my fault), but I thoroughly remember your face and presentation style. Have you considered adding your face or repeating iconic imagery in each of your thumbnails? Use of your face also makes some sense particularly in the videos where it’s not just a podcast style interview. Lots of other channels (you’ll find) tend to have some imagery iconic to their brand (often times the presenter) included in their thumbnails which really helps to stand out, particularly to those who are familiar with the content already when KZbin’s suggestion algo kicks in. Note This is NOT a critique per se, but rather just a minor suggestion, food for thought! Keep up the awesome work! I really love your presentation style.

[@LaunchPadAstronomy]

Thanks for the feedback, Patrick! I've been reluctant to appear on my thumbnails, even though I appear on camera in the videos. Right now, I make sure to have the LPA icon on the thumb, usually in the lower-left corner. But I'm thinking I should try out a new thumb style that's more consistent than just the icon and text. Cheers!

If everything entering a black hole continues to compress to a singularity would it be reasonable to think that that singularity pops out the other side as a big bang?

[@pipertripp]

it seems like it might be difficult for black holes that have sunk down into the centre of the cluster to merge because of conservation of angular momentum. Space is big, and stellar mass black holes are really tiny.

Why we don't see the light sunken in front of black holes but sides only?

[@TheNasaDude]

Because that's the light that can reach our eyes. If a black hole bends light by 90 degrees, what lays left, right, above and below it will appear around it from our perspective. The photons coming from what lies behind it will be steered to the left (and to the right, above and below) around the black hole and go in those directions, and not towards you

Very nice video, just as expected. Minor nitpick: I'm used to NASA labeling some images "artist's depiction" when appropriate, so as not to conflate illustrations (such as 5:02) and animations with astronomical observations. Could you see your way to doing something similar? I realize it becomes clear towards the end of this video when the three scenarios are compared, but it did irritate me a bit earlier.

I'm really curious. In a parallel to the material found in protoplanetary disks around young stars, could the ripped-apart remains of eaten stars orbiting black holes form new planets? A planetary system that evolved around a black hole for the entirety of its existence would be fascinating

[@LaunchPadAstronomy]

If the matter in orbit around the black hole were far enough away and in a stable orbit, then yes. The tricky thing is that tidal disruption events are very dynamic so we wouldn't expect matter to adopt stable orbits, which is why we can see them at all :)

[@360DegreeView-ddsworld]

Thanks 🙏 Christian for all the videos love your work !! Q: shouldn’t this video be tithe Star ‘graveyard’ found in a globular cluster ? As technically aren’t all black holes dead stars ?😀

[@alexv259]

Hello Prof. Ready, I find your video presentations extremely educational for non-astronomy people like myself. First I would like to share with you a sort of disappointing fact I came to know to be true, then I hope you could expand on it with your wealth of knowledge. What has given me a sense of weakening in our ability of looking into other stars and their possible planets, through the method of (forgot its designated name!) planet coming in front of its star and our ability to measure its size and other things, by the amount of light dipping that takes place. Well, I learned that we can ONLY employ such a method ONLY and ONLY for stars and planets that basically must align with the angle of our planet!!! Am I right to find that very limiting factor for us to look into other stars that do not align with our planet. Is it possible to make a video of first defining this issue and then its implication whether it’s a huge deal or not. THANKS!

[@tomfieselmann5906]

Interesting video (despite ten advertisements)! While the possibilities of black holes in globular clusters are, well, possible, I had a thought that with so many possible black holes in so many globular clusters, that at least a couple black holes in just one cluster somewhere in the visible universe would each be "eating" a star and spewing out ionized jets at nearly light speed in opposite directions. This implies that double-jets should be able to be detected coming from the black holes within a single globular cluster. The jets wouldn't have to be parallel, although they might be interacting jets... Have any globular clusters been detected with double, triple, or (wow!) quadruple jets? Our galaxy has some 200+ globular clusters, but to my knowledge, not one has a jet (let alone multiple jets) coming from it. While black holes in globular clusters are possible, I'm skeptical - and that's okay.

[@LaunchPadAstronomy]

Indeed it is. It's just that Proxima orbits Alpha Cen A&B, so I should have said the 'Alpha Centauri system.'

[@saa82vik]

Uhm I'm not an expert on the particular simulations, but a model with several black holes could use more parameter that can be adjusted to fit observed (and very sparse) velocity distribution data than a single black hole model. In other words, if you increase the number of free parameter in he model you are bound to get a better fit. Nice vid very informative.

The moon is more than 3400km in diameter, so 34 million centimeters. It will take 8.4 million years for the moon to recess 1 diameter away. The Moon is 380.000 km away already, so that would mean 8 million years for a 1% change in distance. Pretty stable I would say

[@will2see]

Why do we observe so few high-energy processes (if any) coming from the globular clusters? Why there is no such thing as an 'active' globular cluster. Why we haven't observed star collision in a globular cluster, nor a supernova explosion (I know, the stars in a globular cluster are old and usually not massive enough)? Globular clusters are fascinating objects. I wonder why there is no more research regarding globular clusters. We know so little about them. We are not sure how they form (what is their origin) or what they really represent. For all we know, some of them could be old remnants of galactic nuclei of dwarf galaxies that together formed our current Galaxy. And the best thing is that they may hide answers to what is dark matter (or at least help us get closer to it).

One light-year is about the distance from the sun to the edge of the solar system in the forward direction. How many solar masses are you squeezing into that space?

[@LaunchPadAstronomy]

About 1000-2000 solar masses in half that radius ;)

[@TomLeg]

​@@LaunchPadAstronomy Well, you COULD put 15 * 10^6 suns side by side in a linear light-year, so 1/8 cubic light-year would have room for quite a few suns ... it would just be weird

[@Hallands.]

I suspect the explanation is simple: In young galaxies, the central, intermediate BHs haven’t coalesced yet.

[@TheRevWillNotBeTelevised]

Speaking as a complete layman here: Could 'Dark Matter' be explained by far more black holes than we think and black holes of a greater mass than we currently think?

[@LaunchPadAstronomy]

Interesting question! Black holes could account for part of dark matter's "mass budget", but black holes tend to merge and clump together. Dark matter on the other hand appears to be "non clumping" in that they won't form DM planets or stars. Instead, it seems to form very large structures over enormous volumes of space, which is different from black holes. So yes, while BH's can explain some of dark matter's mass, they don't seem to be able to explain the rest of DM's behavior.

[@TheRevWillNotBeTelevised]

@@LaunchPadAstronomy Fascinating. Many thanks for your response.

[@BigNewGames]

Dark matter is the mistake assuming that gravity is the only force able to move stars in galaxies and bend light around mass where general relativity and the laws of physics fail.

I'm not sure why we haven't solved the issue of possible lost information in black holes. (I'm not actually surprised btw, I just find it amusing) It seems like every week we gain much more understanding of the universe and physics from them. Maybe it's just all about perception. I'm beyond excited to see what we learn in the next year, not to mention 20 or 30 years down the road.... I'll still be searching for channels that cover space, black holes and silly dog videos. ☺️ Information may be lost in a way, but look at all we learn.... Friggin' universe gotta throw us a curve and keep us on our toes. 😂 Wait, now we're back to the curvature of space and time. Ugh, my brain is melting. Oh well.

[@BigNewGames]

The only paradox is assuming that black holes eventually evaporate over time. There is no evidence to suggest that black holes evaporate. It is only a hypothesis that has zero evidence to support.

[@Dragrath1]

Well theorists think they have a number of pretty good resolutions for the so called information paradox but the issue is we lack the ability to make observations with the detail and precision to actually verify any of the proposed solutions. Thus it is likely we will not be able to verify this until we can experimentally make a Kugelblitz black hole or find a nearby enough black hole for detailed observations much closer to the horizon. Both of those potential experiments require Kardashev 2 energy technology to really be feasible which is a bit of a problem

[@dancingwiththedogsdj]

Oh, I guess I should have clarified that I'm not actually surprised about the yet unsolved information paradox... I was thinking more about ironic it is. Black holes may (or may not) destroy information, but we may ultimately learn more about the universe from black holes than anything else. I understand we still have a lot to learn. Can't wait to see what we learn in the future! Thank you for your responses y'all! Hope you have a wonderful weekend!!

[@BigNewGames]

@@dancingwiththedogsdj Black holes do not destroy information. They create information through the process of fusion in their cores.

[@dancingwiththedogsdj]

@@BigNewGames I wonder if they create correct or incorrect information in that core...? Then it still can't cross the event horizon so I guess we'll never know.

Anything. . . anything that might remove the postulation of “dark matter” to resolve problems in Galactic Scale Orbital Mechanics. . . I can agree with that.

[@TheNasaDude]

Well technically black holes are as dark as matter can be... Sooo...

[@ThatBernie]

But dark matter is postulated precisely in order to save the “rules” of Newtonian physics + general relativity. If you get rid of dark matter then you have no choice but to propose some type of theory of Modified Gravity, which would mean that the “rules” of gravity are different at large scales.

[@SernasHeptaDimesionalSpace]

@@ThatBernie In my work matter atracts to matter but not just any matter with any matter pluss matter follows atomic weight and goes by levels.

[@BigNewGames]

@@TheNasaDude Yes, but black holes produce massive amounts of energy, matter space and time, dark matter does not produce anything, not even an electromagnetic signal. General relativity was wrong to assume that nothing can escape the gravity of a black hole. In reality the energy that they emit goes beyond the visual spectrum of light we are able to see. That's why they are black. not because energy cannot escape them. Yes I know it's conjecture. Eventually this will become an accepted fact. Black holes produce massive amounts of energy in a wavelength too short to be seen by the naked eye. We need high energy detectors to see the light coming from them.
