    It's pretty late in the series to say this now, but I'll say it anyway. I love the way Phil talks about anything in this series. There's a "childlike wonder" in his face and voice clearly showing that he's passionate about astronomy and what heavenly body is topic to a particular episode. Things like this make me wish I could afford the Patereon subscription.

    Which PM? The tea seller? You have to be so stupid to put a tea seller as the prime minister of India and expect the country to develop. Get serious. The country has gone backwards in the past couple of years since you made him a PM. Worse part is most educated people in India cheer him on. Look at the dollar to rupee, look at the high cost of living. Look at the economy grading of India by the rating agencies, you are together with countries like Pakistan, Bangladesh other African countries and you think you have done well? Misplaced priorities.. start building toilets and clean up your cities before even thinking of going to the moon. Also don't ever compare yourselves with China. They are 50 years ahead of you. If I was a voter in India, I would rather vote for a young vibrant educated leader like Raul Gandhi than vote for a tea seller. Why don't you employ a tea seller in your company as management and expect your company to prosper?

    Dragoneye I don't think that's true at all. NASA has always been good about coming up with cool names. Just look at the Mars rovers: Spirit, Opportunity, Curiosity and Sojourner; they _could_ have all been MER1,2,3,4... but that doesn't inspire the average person. And they traditionally use a lot of Greek names: the Gemini and Apollo Programs, the Saturn Rocket, the Atlantis Shuttle. NASA would _never_ get adequate funding it they named something as ambitious as a moon colony "Lunar Base 1" that's so boring; normal military bases don't even have names that boring.

  • @thesimsdreamer
    @thesimsdreamer8 жыл бұрын

    Great, concise video with a lot of information and presented very well. Thank you. I vote that we rename Earth's moon, and call it Luna. Calling it "The Moon" is similar to always calling your own child "The Kid", but calling other people's children by their names. Also, if we were to adopt the name "Luna" as the proper name of our moon, then the "face" we see during full moon should be called "The Lady in the Moon", or "The Face of Luna". Also, a "respectable" name of the Moon could be "Lady Luna" ("Lady Luna is rising her full face tonight"). Also, I agree with +TheJaredtheJaredlong , a lunar colony someday on Lady Luna could be called Selenia, that sound great! Right, because the moon's name in Latin is Luna, and in Greek it is Selene. To be more complete, note that the names for the Greek/Roman goddess of the moon were Luna, Artemis Diana, Phoebe, Selene, and Cynthia (I guess they couldn't make up their minds what to call her, lol). My suggestion stands, though, to give the moon the name "Luna", since "lunar" is the adjective we use when referencing the moon. Although, I image this name change will never happen, as people are too accustomed to calling it "the moon"; it would be about as weird and difficult to adopt as changing Earth's name would be.

    Would have been cool if you explored the Georeactor Theory in this episode. This new theory on the formation of the moon would explain much more than the Giant Impact Theory. If you are wondering, in short what the Georeactor theory is, is that on the boundry between the mantel and outer core, called the D" (D-double prime), alot of fissile material (uruanium and thorium) collected. It just wasnt dense enough to start a nuclear reaction. Then a large comet or asteroid hit the earth causing a compressive shockwave which lead to a giant (and I mean f'ing huge) explosion which flung huge pieces of the mantel and crust into orbit. This explains the isotopic similarities and dissimilarities (some isotopes are more common deep down than in the crust of the earth) between the earth and moon. It is also testable by drilling into the crust of the moon and looking for an isotope of Xeon that forms from the decay of uranium and thorium. It probably isnt THE theory to explain the formation, but the Giant imapct theory has far less going for it in explaining what we find on the moon. If you want some extra information here is a link: www.sciencedirect.com.proxy.library.uu.nl/science/article/pii/S0009254112006262/pdfft?md5=f85df82e5eddfd7a42ea96c37e570060&pid=1-s2.0-S0009254112006262-main.pdf

    Digs Fossils-n-Knives their composition and morphology suggest impacts, or at least some sort of energetic event(s) that caused the release of lava to form basalt "seas" that didn't happen on the far side. In other words if the earth shielded the moon on the near side there would actually more things that need explaining, instead of less... If on the other hand the moon was simply smoother and less cratered but with the same composition then such a theory would make a lot of sense.

    The Moon _is_ the only one, just like Venus is the only Venus. The Moon is the name of that object in English. Once we discovered that other planets had natural satellites, we decided to call those "moons", making a generic out of what had been a proper noun. Much like calling all facial tissue "kleenex" no matter who makes it. Imagine if we had decided to call all other planets "earths". It would be the same kind of thing.

    Alex Becker Of course there's evidence to support it, no one would really take it serious if it didn't. However, it isn't widely accepted in the scientific community, therefore it's still a hypothesis. Just because there's evidence supporting some aspects of it (you mention isotopes, which I'm assuming relates to the age) doesn't mean there couldn't be inconsistencies in other parts. Scientist are supposed to have high expectations for any idea looking to explain any natural phenomenon or answer any question. If the resounding majority won't accept it, then it isn't a theory. Now it could actually be a theory and i may simply be unaware of it, but if it is I'm sure you'll correct me on it. :)

    To expand a bit on what Nolan Thiessen, oceanic crust is young (several hundreds of millions of years), and gets formed and subducted constantly, and based on their rates of motion we know the atlantic ocean didn't exist up to 200 millions years ago (c.f. Pangea) and the pacific ocean plates were part of a huge ocean that covered most of the earth called Panthalassa. But on the time scales of the earth's full history, and the formation of the moon, this is peanuts (about 200 million years vs. 4 billion years...). The current hypothesis is that the Pacific ocean (well, Panthalassa) started to form about 800 million years ago, when Rodinia, the supercontinent that preceded Pangea, started breaking apart. In other words there seems to be a cycle (called the Wilson cycle), where the continental land masses break apart from a supercontinent, drift around the world, and then smoosh together to form a new one, and currently we're in the middle of that cycle where the pacific ocean is the remnant of the previous super ocean and the atlantic ocean is the new one that formed in the middle of Pangea. But this entire multi-billion year tectonic plate process is still younger than the early processes that formed the moon, and only started happening after the earth cooled down. Note that although there's plenty of evidence to support these ideas in general the particular details are not as clear (especially when you try and reconstruct earlier times) and it's still a very active field of research.
