At t=2:23, the light represented at the violet end of the spectrum is moving slower than the light waves representing the red end while they're in the prism. Later, at t=2:33, violet is faster in the prism than the red. Ignoring the contradiction, my understanding is that the speed of light may be slower in one transparent medium than another, (glass vs. air) but its speed is constant independent of frequency. Am I missing something or are these representations exercising artistic license?

[@mal2ksc]

My utterly non-expert thought is that friction in normal matter may put an upper bound on rotation speed. The inner tracks are still orbiting more frequently than the outer because the distance is shorter, so baryonic matter may lose energy to friction at an ever-growing rate as the rotation speed goes up. The reason a galaxy could spin up like that would be because that baryonic matter is already gone. Less load on the engine, and it's _able_ to spin faster, but that doesn't necessarily mean it will. So in principle all galaxies could spin much faster, but they've settled in at the point that doesn't cause too much drag. The ones with less dragging material settle in at a higher sustained speed, but only if they had it to start with. The energy that drives starbursts has to come from somewhere, after all. Maybe it saps angular momentum even when it's not shouting about it by forming stars. Also, I was pleased as punch to see there was a Vera Rubin Telescope. I was, however, disappointed to find it was just a renamed LSST, rather than an entirely a new telescope (because more telescopes is more good). Ah well, you can't win them all.

[@unclvinny]

Dr. Becky, I love your channel! When you read about new galaxies like these, do you build a quick mental map of where it is? Like....which direction you’d point to see it, what other galaxies/universe landmarks it’s near, etc? For things in the Milky Way, the zodiac would be the map I guess I’d use, but for galaxies they could be anywhere in the skies. Just wondering! I have a terrible mental map of the Universe, and it’d be so cool to hear about what yours is like.

[@stargazer7644]

Most astrophysicists don't actually operate telescopes. They just give the operator or computer RA and Dec coordinates so nobody needs to know intuitively where it is in the sky, other than for timing purposes to tell when the target is up in the night sky for good viewing (and they'll use software to tell them that). All computerized telescopes use this coordinate system. For example, to ISOFDHS27's coordinates are RA 22h 32m 47.6994s Dec -60d 33m 35.744s J2000. You can punch this into any computerized scope and it'll point at that spot in the sky.

[@preetagnihotri6540]

Hello Dr. Becky! I was wondering about the normal matter that you were talking about at 12:18 in this video. You said that there might be some normal matter which doesn't radiate, and hence is invisible to us. And then you talked about what and why would it be happening that galaxies throw out some amount of normal matter to flatten the curve. Here's my point : why is it that the galaxy has to throw out that matter, why wouldn't that matter have always been there? (I am not sure about the grammar I just used.) What I want to say is that maybe when the galaxy was forming by gravitationally pulling the gas (fuel for stars), some normal matter was attracted to it, but just enough to be bound to the Galaxy and rotating around it, and not enough to clump into a star. This can explain the hypothesis of normal invisible matter without having to worry about the process which expelled this matter outside, because it was never inside the Galaxy in the first place. Can this be verified? Or is it faulty somewhere? Waiting for a response, and thanking you in advance.

[@preetagnihotri6540]

I don't think I have explained my point very well. I am falling short of words. Please let me know if this was unclear.

[@aresaurelian]

If the gravity well is strong enough, perhaps even the aether inducing inertia is stripped from the outskirts, hence less inertia to overcome.

[@eliyasne9695]

9:17 Yea, but if you give the heaviest galaxy a title like "Giant" or something like that, then when you find the next biggest galaxy you'll have to call it "Giant 2" because Giant is already in use. Then, after the discovery of many more biggest ones you might get to "Giant 34" and tire off saying Giant all the time so you'll just call it "G-34". Oh wait, look were we got, we're back to the meaningless numbers and letters.

Dr. Becky, An off topic side question... Do you think Oumuamua could have been a star fragment? Similar to how lava spits are made. To me that shape and length have an uncanny resemblance..... My hypothesis- The star starts to produce iron and (1) shoots it out from the core (2) the iron is molten in the outer layers of the star from many commit & asteroid impacts and when the star explodes the spit is created and thrown off from the surface. I do a lot of R&D in my day job and these two possibilities made the most sense to me. Your thoughts Doctor?

Pretty much everything solid in the universe (including you) is a star fragment. That's where the elements heavier than helium come from.

Hello Dr. B. et al, Maybe ISOHDFS27 should just be called "Meatloaf". Or even better: "Disaster Area" after the heavy metal band in The Hitchhiker's Guide to the Galaxy. I found a wiki page with the following excerpt from the show: "Their songs are on the whole very simple and mostly follow the familiar theme of boy-being meets girl-being beneath silvery moon, which then explodes for no adequately explored reason. Regular concert goers judged that the best sound balance was usually to be heard from within large concrete bunkers some thirty-seven miles away from the stage, whilst the musicians themselves played their instruments by remote control from within a heavily insulated spaceship which stayed in orbit around the planet - or more frequently around a completely different planet. Many worlds have now banned their act altogether, sometimes for artistic reasons, but most commonly because the band's public address system contravenes local strategic arms limitations treaties. This has not, however, stopped their earnings from pushing back the boundaries of hypermathematics, and their chief research accountant has recently been appointed Professor of Neomathematics at the the University of Maximegalon, in recognition of both his General and his Special Theories of Disaster Area Tax Returns, in which he proves that the whole fabric of the space-time continuum is not merely curved, it is in fact totally bent.

Not including gravitational stresses as they would be hard to calculate.

[@massimookissed1023]

If anything there's too much radiation as you get closer to the galactic centre. More frequent gamma ray bursts too. Galaxies themselves may well have habitable zones. Too much radiation in the centre, not enough heavy elements out at the rim.

There's something implied by this video for which I'd like to get some clarity. I assume that in this video, when you refer to the "speed" of a galaxy, you're referring to its angular velocity. If a galaxy were sufficiently large, at some point wouldn't stars at the rim have a linear velocity exceeding the speed of light even if you ignore acceleration from dark matter (this is simple geometry)? Is this possible, and if so, why and if not, why not?

Galaxies don't fly apart because of the elasticity of space time. I believe that space time itself has a property in a quantum scale that makes the entire space time elastic (dark energy). If we imagine two particles close to one another in an elastic structure going around the particles, the structure between them will be more open and the outer space time squeezes them to opposite direction, that is gravity. If we imagine in large scale, the process is the same , the entire space time around the galaxy holds the galaxy by squeezing in all directions to the center, the differences of elasticity within galaxies is what pushes and holds everything in the galaxy together because of the long distance within galaxies, plus, all solar systems in the Galaxy is in constant movement and constantly stretching space time, it takes millions of years to reach the opposite side of the Galaxy, that open space still affects the complexity of attraction among solar systems while the stretching going farther away from the Galaxy won't affect anymore. My conclusion is, the more speed the Galaxy rotates the more accumulation of open space creates in the galaxy and the more is the force to the center. Space time stretches in a spiral trajectory and part of the trajectory may go around the center and turn back to the starting point. It's a very complex calculation using integration, but it's possible to approach this evidence.

You already said a good name. Call it "Big Behemoth". Or even better "Becky's Big Behemoth"! I realized the possible alliteration as I was typing. Sounds like we need more examples of even faster spinning or heavier galaxies with relatively reduced normal matter. Are two enough to hypothesize that the curve flattens or hypothesize anything really? We just need more data points at the upper ends of the chart, if those galaxies exist. Not sure what camera you have but I use a d5300 which has a 10minute limit, but after playing with the settings I set it to 30 minutes. You might be able to change that if you look it up. And also consider setting up something permanent with a camlink, dummy battery, and obs studio.

Godzilla0815 Rapidly spinning? *Gamera* Galaxy, surely.

Godzilla as in a fake monster on tv just like the fake planets on tv and in books?

[@MriInterocitor]

@@thejollyman Godzilla as in the friend to all children, protector of humanity from (among others) lying con men like flat-earth preachers.

MriInterocitor How is asking someone to check their reality preaching I feel you’ve been misdirected

[@MriInterocitor]

@@thejollyman When you repeat proven falsehoods knowingly, and when you deny well-established facts (as opposed to showing an error in either measurements or interpretation), you are a liar. Bye now.

Lol, hi from Scotland and props for following up a sentence with Scotland in it with reigning as it sounds like a common occupational hazard of being a Scot!

Does the axis of rotation relative to us affect the ability to determine the speed of rotation? Can it be determined from the measurements?

[@stargazer7644]

Yes, the instrument Dr. Becky is describing actually measures radial velocity towards/away from us and not actual velocity relative to the galaxy center. However, since you can generally see the spiral disk, you can tell how it is oriented towards us and correct for that angle difference (up to a point). If a galaxy is completely face on to us (pole pointed towards us) you won't measure any radial rotational velocity with this method, and therefore you can't correct for the angle.
