    This is a corrected reupload of yesterday's Venus episode!
    Venus is a gorgeous naked-eye planet, hanging like a diamond in the twilight -- but it’s beauty is best looked at from afar. Even though Mercury is closer to the sun, Venus is the hottest planet in the solar system, due to a runaway greenhouse effect, and has the most volcanic activity in the solar system. Its north and south poles were flipped, causing it to rotate backwards and making for very strange days on this beautiful but inhospitable world.

      Vincent Carmiggelt There was an insensitive joke made in the previous version, that we didn't recognize as such until several commenters pointed it out to us.. It wasn't something that we could readily address with an annotation (which we've done in the past with factual errors) and we decided that we would rather lose the views on the prior version than stand behind something offensive. We're sorry for not catching it ourselves and letting the original version go up as it did.

      You are correct and our Ancestors referred to Venus at different times as both !
      Because Venus was a planet behaving like a Comet, which terrified the human race in what has become known in Mythological History as the "War of the Gods". If you put the "Electric Universe" branch of Science together with the study of Mythological History, some terrifying realities begin to reveal themselves. The stories of the Catastrophes that left evidence of damage to our planet 6,000-10,000 years ago, now take on a sinister reality. A current problem within Science is that Scientists are more and more reluctant to interface with other branches of Science. For example normal Astronomers refuse to interface with Radio Astronomers. So the obvious is no longer obvious to any of them.
      The Universe IS Electrical, there are NO islands in Space. This fact is just about to turn Science on its head, thanks not to Science but a Hi-Tech Electrical Engineering Company who have accidentally proved the "Electric Sun" model in July 2019. Which will probably prove to be the biggest disruption to Science since Sir Isaac Newtons publication of what became the Laws of Gravity in 1687. The result will be like an Atomic bomb to mainstream Science when it realises many of its cherished Theories, have just be thrown in the dustbin.

    Interesting story about misidentifying Venus. HMAS Sydney was fighting in the Mediterranean in early WW2. At one point, the ship began to fire on what they thought was an Italian high altitude spotter aircraft. Eventually, after expending most of the ammunition for their heavy anti aircraft battery, the ship realized that they were firing at Venus.

      On Monday, 2019 November 11, Mercury will transit the Sun for the first time since 2016. The transit or passage of a planet across the face of the Sun is a relatively rare occurrence. As seen from Earth, only transits of Mercury and Venus are possible. There are approximately 13 transits of Mercury each century. In comparison, transits of Venus occur in pairs with more than a century separating each pair.

      Professor Velikovsky said in his 1950 book "Worlds in Collision" that "When you get to Venus you will find the surface temperature to be 850F+". He was scoffed at and labelled a Heretic, but in 1962 when the first probe to Venus landed it recorded a surface temperature of 854F , before it melted 8 minutes later!!!
      Venus WAS a Comet, which explains its obscene heat. Its molten like surface totally devoid of craters also implies it is a recent arrival in the solar system. NASA now suspect Venus wasn't the only recent arrival in our solar system. Saturn is also under suspicion as having been a small brown dwarf type star dragged in some time in the past, which died as a star upon arrival. (Due to the electrical and electro-magnetic disruptions that two Stars in one system would create). In Saturn's "death throes" it would have ejected matter, and enough to create what we now call Venus. This possibility also helps explain the terrifying stories of our Ancestors which are usually referred to in Mythological History as the "War of the Gods". Our ancestors didn't understand science but they did record what they saw, and we do know that Earth was damaged by Cataclysms around 6,000-10,000 years ago. All of which could be explained by a chunk of rock as big as Venus, coming close to Earth, before settling into is current and obscenely precise orbit around the Sun. Such a precise orbit is also another indication the planet is a new arrival, as the orbit hasn't had time to be slightly disrupted by the various gravitational pulls of all the other planets !

Don't know how accurate that is, but it's a damn memorable image!

    Thanks for the Venus info. About 31 years ago, when he was maybe 9, my son and I were coming ashore from his 8' sailboat, and saw Mercury in transit, crossing the sun from left to right and diagonal down about 40° from horizontal. It looked like the image here but crossing the sun's lower half. The sun was around 10° from the western horizon, and the cloud layer was just thick enough to see the sun without it being too bright to look at. Chance of a lifetime.

  • @rafabulsing
    @rafabulsing 9 років тому +170

    Seriously, how can people be so easily offended? Let's analize the joke, shall we?
    The joke wasn't "You were expecting a woman, and got a man". The joke is " you were expecting something beautiful, and got Phil".
    Seriously. That's the first time I've ever seen anyone get offended by a self deprecating joke. He was literally the butt of his own joke, and somehow people managed to be offended. Because apparently some people are so self-centered they can't conceive that something may not be about them, ever.
    Why? Why must people always try to interpret things in the worst possible way? Why take any statement, and think, "Well, let's see if there's any interpretation that could ever offend anyone, no matter how flimsy it is, or how clear it is that that's NOT what he means"?
    "Man, I really should start hitting the gym" "Why? Do you think being fat is wrong? Do you think less of fat people? That's problematic!"
    "If I somehow could be a woman for one day, I would..." "Whoa whoa whoa, for a day? Trans people can't choose to be their gender for 'one day'! Don't you diminish trans people problems, please"
    "I love my father!" "Well, I lost my father 27 years ago, and even if there's no way for you to know this, you are insensitive for not think about the possibility that this might ever cause someone discomfort, however small it is".
    It's utterly ridiculous behavior, and it's sad to see intelligent people such as the creators of this channel having to bow to their desires out of fear of a PR disaster. Really sad.

      Rafael Bulsing Thank you. Your 2nd sentence in the beginning really is the main point. It's not even about Phil's "intentions" behind the statement. Instead, no matter what the intention, there is a clear semantic difference between the two cases, and Phil's joke/sentence/imagery was clearly not about "maleness mixed with female body" but a self-deprecating comment of "look at my personal, individual face".

    For everyone wondering what the joke was that got removed for the reupload: The original video at 3:21 had that picture again of the naked woman holding God-knows-what between her legs (from 0:06) but on "but up close ... yikes" the animation zoomed in on her face which at the same time turned into Phil Plait. This was perceived to be trans-phobic. To quote Greenwickpress's comment on the original video:
    "You may not have intended to do so, but the joke about Venus being unattractive in person is problematic. It looks on the surface to be transphobic, because the implication is that the viewer was expecting to see a beautiful cisgender woman, but was fooled and instead found a man, whom they found unattractive. It would have been better to do something else to show the person depicted wasn't attractive."

      @rdreher7380 9 років тому +6

      Diana Peña At some point I find you too radical. I don't think that joke was really that offensive, but there are such things as offensive jokes, and offending people is wrong. You seem to think everyone should just be crass, nasty, and hardhearted, but in the real world people need concern for one another (you know because we live, work, and share a planet together), and a huge part of that is understanding how our actions, including jokes, can affect other people, and taking responsibility for that.
      Now what is offensive can be very complicated. The same joke can be offensive in one context and fine in another, so long as everyone is on the same page. When misunderstanding arises, the correct thing to do is explain yourself and apologize, not berate the offended for being too soft or sensitive. Not everyone is going to tough it out, and why should they? What you should do is learn to better communicate your humor, better contextualize it, that is take responsibility.
      Of course, there are sometimes when you can't do that. When you speak to a large audience, you can't have concern for everyone. You can't stifle you're speech because of a minority that just wont give you the benefit of the doubt. Then again, you don't want to just play to the tyranny of the majority and allow certain groups to be marginalized. These are all complicated issues to deal with, not just simple "comedy has no limits."

  • @SteamKing2160
    @SteamKing2160 8 років тому +3

    Another fun fact about Venus is that the surface is as flat as the great plains in the United States and the planet's clouds race around the planet in 4 days. Also, the craters are rare on Venus is because the biggest space rocks make it to the surface, the rest vaporize in the super-dense atmosphere. Michael Goldfarb refers to Venus' big craters as the pancakes in a barrel of syrup. If you took Venus and put any sort of water on its surface (while stripping its dense atmosphere that's 90 times as dense as ours), it would most likely resemble a water planet.

      if you look at the topographical map of Venus, you would see a mountain range circling the planet while both north and south lands, for the most part, would be flat and yes the atmosphere and its clouds circle the planet in 4 days.

    I remember in grade school reading a short story about human colonization of Venus. It was obviously before anything of substance was discovered about Venus, since the author portrayed it as having grey trees and octopuses living in the trees... but interesting. We need to go back to Venus. The USSR was the only one to land something on Venus, but the US should too. Especially as we learn more about how to build structures that can survive intense heat and pressure. If we get a radar device there and landed, even if it only remains online for a few minutes or hours (the Soviet one lasted a few minutes before being crushed by the atmosphere), we could maybe be able to tell what the core of Venus is like.

    There is an exception to the naming convention on Venus. One feature is named Maxwell Montes after James Clerk Maxwell. Maxwell's equations describe electromagnetism, and without radar we would have no way of detecting the surface features.

    Please don't tell me the Venus/Phil joke was removed. As a member of a minority which is sometimes violently abused and sometimes frustratingly overprotected, I think it's nice that we're able to loosen up and laugh at ourselves. If nothing else, self-censorship of this sort sends a message that trans- people are "an edgy subject" and we should "step on our toes around them" when I'm sure that the intention is one of acceptance and equality.

      Diana Peña I know the feeling. I'm gay and I can't stand it when gay jokes are treated as offensive. Now, for the most part, they are rather bad jokes, mainly because people think that if your joke is 'edgy' it's instantly good and in reality it just doesn't work like that.
      I hope we eventually realize that equality isn't something you can force into place through censorship or shaming, it's something you need to work at by educating people from a young age, teaching them that humanity is a big, complicated and diverse mess of a species, but we're all worthy of the same respect. And we're also all equally appropriate for jokes.
      I don't want to be treated as a fragile item just because I'm gay: now that *is* offensive.

      13ullseye Same here. Got to agree with that.

    • @demianhaki7598
      @demianhaki7598 9 років тому +5

      13ullseye On a case-by-case basis, I would argue that Phil & the producers are obviously entitled to decide whether or how much they care about not offending anyone, no matter what their own initial intentions. So if they decided to say "You know, in this case, I really care more about the feelings of a group of people than about my random silly joke, so I'm gonna take out the joke", fair enough. It's their product, they can call the shots.However, as a matter of principle, I would argue that focussing merely on people's reaction and perception of a statement/issue/argument is not a feasable way of a) determining cases of discrimination/harm or b) balancing psychological protection with freedom of expression. Going by people's perception of an issue alone is just too arbitrary. It certainly matters, but it's not the only thing that should matter when we try to tell if a certain statement/joke etc. is ok or not.
      So, while we should obviously be very vigilant about respecting the dignity of others and protecting people from discrimination and harm, we should try to find some indicators that help us to identify cases of actual discrimination or bullying slightly more objectively. One thing that might help is to analyse respective statement, imagery, jokes more thouroughly, instead of just saying "there are some possible associations of this with the thing that I'm offended by".
      For instance, in the original video, Phil made a joke about how some things appear less beautiful from up close then from afar. The aspect of "beauty" was represented by the figure of a woman, the aspect of "ugliness" was represented by his face in a self-depricating manner. Now, crucially, the ugliness was not represented by just any male face. If so, the imagery would have equated "ugliness" with "maleness", or more specifically", it would have equated "ugliness" with "maleness mixed with the female form". That would have certainly be transphobic in its message, no matter if it had been intended or not.
      However, in the original joke, ugliness was not equated with "maleness mixed with female body", but very obviously only with "me, Phil, as an individual". That perception does not just depend on Phil's intention. There is an obvious, objective semantic difference between the two cases which we have to acknowledge unless we want our understanding of language to become completely arbitrary. If we allow the meaning of a sentence to be determined by people's subjective associations/interpretations alone, then we can hardly expect to get through a single conversation or debate without offending at least someone. Therefore, if only for pragmatic reasons, we should probably agree on the principle that we should pay attention to the semantic details of statements, no matter how we feel about them subjectively and no matter what intentions the speaker had. If a speaker had good intentions, but the semantic analysis shows that the statement was clearly offensive, then it's offensive. If the semantic analysis shows that the statement was really harmless, but someone perceives it as offensive nonetheless. Tough luck.
      That, again, only applies to when we think about which kind of linguistic standards of debate we want to follow. In this particular case, again, Phil & Co. are obviously free to decide whether they want to give in to feelings of being offended, no matter whether this perception is semantically justified or not.

    • @13ullseye
      @13ullseye 9 років тому +2

      Demian Haki That was probably the most eloquently posed comment I've ever seen on this website, well done; I couldn't have said it better myself. Especially with _"If we allow the meaning of a sentence to be determined by people's subjective associations/interpretations alone, then we can hardly expect to get through a single conversation or debate without offending at least someone."_ you really hit the nail on the head.
      I get your point about them being free to decide for themselves, but when circumstances like this arise I feel like people are often too quick to act in favor of the offended individual. For me it always boiled down to a situation of _someone_ is *always* going to be offended, and you can't please everyone, so it irritates me when people cater to the whims of the overly sensitive because it's just a waste of time and effort.

    • @demianhaki7598
      @demianhaki7598 9 років тому +1

      13ullseye Regarding the catering to victims, I also think it can be problematic when it has harmful effects in real life, e.g. when a university seminar is cancelled because of the uncomfortable ideas that were mentioned/discussed.
      In this case here, I might say "Ok, fair enough, Phil gave a shoutout to a marginalized group. Didn't hurt us and maybe brought a bit of attention to their sensitivities and needs. It was a gesture of paying respect and acknowledging their struggle, taking it seriously".
      But I agree that this kind of apologizing behaviour should not become a kneejerk reaction. It should be possible to say in some cases: "I acknowledge that somebody felt uncomfortable about sth, I can even see that somebody might have felt hurt, but, while I have sympathy, I have evaluated my actions and I maintain that what I have said was inherently harmless in and of itself (independet of my intentions), and since we cannot reasonably adopt the idea that one could only speak in such a way that any kind of negative association is impossible, I consider it ok to express my harmless statement"

He was made aware of it, saw how it could be seen as offensive, and *wanted to* change it. So now he has to act in a way that he himself perceives as negative so as not to offend your delicate sensibilities? If I learned that a word I used innocently was insulting to a disenfranchised group I would change it. Hell, I used to use the word 'retarded' all the time.

      SteamKing2160 I never said on the SURFACE, lemme quickly bold the part you should have paid attention to, "yet it makes a better colony idea than Mars, seriously, Venusian *sky cities* are more habitable than Mars bunkers." Because at a certain point in the Venusian atmosphere, perfect conditions are met, oxygen, habitable temperatures, no acid rain, earth-like pressure, essentially, perfection, all we need is to sift the Venusian atmosphere for water vapor. But with all this, all we need is to build cities with reinforced poles anchored to the surface, and let the atmosphere to the balancing. But another idea is that we strip the Venusian atmosphere to the point where the pressure isn't too high, and reduce the greenhouse affect to where there can be liquid water, then move the gasses that weren't needed to mars and give mars a thick atmosphere, but only thick enough to give it liquid water, and also drill into mars and trigger massive earthquakes to give mars a active internal structure with a liquid, flowing core to give it a magnetic field as well. As well as launch thermo-nuclear bombs onto its frozen ice-cap to melt the water and much more.

      Sounds like a good plan. I get what you are saying now. If Im not, then that's really ok cause even though I am for terraforming it sounds like an extremely costly thing to do.

      SteamKing2160 Well by then we would probably have enough the technology to do all that.

      true but I don't think NASA is concerned about terraforming yet.

    When you started talking about evenly spaced craters from millions of years ago were a mystery I immediately thought of the Reapers from Mass Effect..

    CrashCourse Question: if the clouds on Venus are reflective, shouldn't that result in a cooling effect?
