Nice work-your video is very informative. We discuss all of these topics in my Introduction to Astronomy course and they're an important part of the history of figuring out our place in the universe and its scale. We also do lab exercises using Henrietta Leavitt's period-luminosity relationship of Cepheid variables as well as try to determine the location of the Galactic center using measurements of globular clusters. A couple of small points: The photo at 8:30 shows the 100-inch Hooker reflecting telescope on Mount Wilson, not the 60-inch reflecting telescope. Also, globular clusters orbit the center of the Milky Way and do cross through the Galactic plane. It's just that those in the plane are hard to see and analyze. Globulars away from that "zone of avoidance" are easily studied. Shapley hypothesized the globular clusters are gravitationally bound to a "center of gravity" that coincides with the Galactic center. He was correct, but his estimate of the Galactic center's distance was off because the widespread distribution of interstellar dust had not yet been discovered. This resulted in Shapley misinterpreting the brightness of Cepheids in the globules and overestimating the cluster distances.

In Denmark we also have a "real giant": Tyge (Tycho) Brahe, who in 1572 saw a "new" star, and wrote a book about it (De Nova Stella/The New Star). This is why an exploding and dying star is - still named a "Nova"! He realized that the Universe wasn't as told but he could have been - burned by The Holy Church, at that time, for telling the truth, so he found an intermediate solution, with the Earth still as the Center, but it and the rest of the planets going round the - Sun! And, after his death, all his notes became the basis of his former pupil, Johannes Kepler's later construction of the planets movement as eclipses! The Nobleman, Tycho was very protective of his observations and knowledge, so it wasn't till after his death in his exile, Prag, that his "common" widow gave Kepler access to his papers! The new Danish King didn't want to pay for his exorbitant expenses, so he had to move from Denmark and found a new home in Prag, where he is also buried inside, and with a stone in the floor, in the Tejn Church/Tynsky Chrám. The remnants of his "new star" is still to be seen in Cassiopeia. But the Crater on the Moon which is named: "Tycho" is larger than "Copernicus", because the naming person liked the Tycho Brahe Version more than the Copernicus Version of the Universe! 😁

My question for physicist-astronomers: How do we know that the measurements we take from earth are accurate to objects incomprehensibly far away? For example, we know the properties of reflected light in Earth's atmosphere enable objects that are beyond visible distance to be 'seen' (due to reflections that can be created by a suitably dense water vapor in the air) by people beyond the horizon sight line. In using this example, I don't mean to imply that I think earth's atmosphere would create faulty data. Rather, how do we know that between earth and these far away objects, environmental conditions in the galaxy/universe are so consistent that there is no reason to question our measurements? Doesn't it stand to reason that as soon as we get a different view from a nearby star that we may triangulate things far differently than we see them now? Between cosmic background noise, radiation, dark matter, and the actual not-quite-nothing in the cosmic void, I always wonder why I never hear any qualifications that astronomers could be wrong about our measurements.
@CarpetOfStars_98 Жыл бұрын
Important question! Astronomic findings (like almost all of scientific findings) are questionend a lot. It's just that these things don't really get a spotlight in science-journalism. There is also a lot of uncertainty on many measurements, but here on youtube they often get omitted, because it sounds less cool I guess. Historic findings are also reviewed with newer technology, and sometimes we get different numbers decades later. So nothing is carved in stone here :) Then how can we be reasonably sure about anything? No I'm no expert, but I think a key component is comparison. If we can measure the same thing twice with different methods, and both measurements agree, then it stands to reason that the result is quite credible. Of course it also happens, that we measure a thing with numerous different methods, and they all disagree with each other, so we're not particular sure about these ones. (I think that's the case with the accelerationof the expansion of the universe, but don't take my word for that)

In much the same manner as the early unmanned Apollo missions, which peered back at Earth, initially capturing it in black and white before transitioning to full-color imagery from afar, humanity was granted its first glimpse of our planet as a celestial object within the solar system. Prior to this, our perspective was limited to observing other celestial bodies such as the moon, sun, and planets, but not our own home. It's conceivable that as our technological prowess advances, perhaps in a few thousand years, humanity may possess the capability to cast our gaze back upon our galaxy, offering a profound new perspective on our place in the cosmos.

I am not the expert here but it has been made as simple as I can explain it. Having figured out the distance of the moon from reflective light the astronomical unit of measure is not accurate but very close. Then it went from one planet to the other, Distance to mars. Vessels have been sent out to confirm those distances of measure. Knowing where this planet is in or galaxy will be about 95 percent accurate. As long as we are on one side of the center we can just count the stars and where they are. Looking at the entire shape and size of the Galaxy would be from outside looking in. I don't think they are that accurate as many stars behind the center focal point will not be seen because of the closer ones. Too many speculate, when Science confirms, through multiple identical answers, over the very same question. Tested over and over again, and got the same results. In Science that is Quantified.

How did Hubble know that the variable star was in Andromeda and not in our own galaxy or a galaxy beyond Andromeda? It's amazing how much astronomers have learned on so little information
@michaelbauers8800 Жыл бұрын
He used the information we had on the luminosity of the variables vs their period, which Henrietta figured out. With that information astronomers could compute approximate distance to the variable stars. I think that's how we computed distance to variable stars. So if we observed some variable star in Andromeda, and figured out the period of it's variability, we could approximate it's luminosity, and compare it to our observation of it's luminosity to compute distance. I apologize in advance if I explained this wrong.

Can we reverse that expansion and arrive at a point of origin? Looking at the universe, and it’s expansion is certainly important, but, wouldn’t it be just as important to know the point of origin?

Poor Henrietta Leavitt. She was a Radcliff College-educated astronomer who also made several other significant cosmological findings during her lifetime. Because of her gender, the best job she could obtain in her field was as a 30¢/hour research assistant at Harvard, comparing photographic plates. Although to this day, her discoveries continue to contribute to our understanding of the universe and easily exceed the subjective and sometimes ‘what-were-they-thinking’ criteria used to award (or not award) many Nobel Prizes, she received no recognition during her lifetime. She died two years before the Hooker Telescope was completed, but never would have been allowed to operate it. George Hale, who planned and led the telescope’s construction, considered women a distraction, and visiting astronomers weren’t even allowed to bring their wives. Even the chauvinistic Hale, however, later said she deserved a Nobel Prize.
