Carl Sagan's Cosmos Episode 4 part4

[RJL738]

Amazingly it turns out that Saturn's have their own atmosphere. Saturn's rings are alote alrger than first thought and art almsot 99 percent water ice. Saturn actually has a thin large ring around it that is the volume of more than a billion Earth's. It is possible that one of Saturn's moons has a ring system of it's own, this is just one planet. What systems must there be around more stars in the known universe than the grains of sand on all the beaches of ther world.

"The entire evolution of the Moon is a story of catastrophy."

Just like my sex life :(

[WrestlingHeretic]

You can tell Sagan is having a little fun at Velikovsky's expense.

[RideMyBMW]

Guys, the moon is 1/3 the size of Earth, the solar system´s biggest moon/planet ratio. The moon should have impacted Earth millions of years ago. BTW, try explaining why the moon is exactly 400 times smaller than the sun, and also 400 times farther away so as to allow for a perfect solar and lunar eclipse...

[kazath]

@RideMyBMW No it shouldn't have impacted. The moon is established to have formed by a proto-planetary collision with Earth during it's infancy. Explained by Ubi below the moon is, and has always moved away from us. So it shouldn't have impacted us, neither will it do so either in it's current form.

[corrosivetrip]

@RideMyBMW your kind will be hunted and slaughtered like the weak little sheep you are sooner or later. pray to your false god it isnt my team that comes across you

[RideMyBMW]

@corrosivetrip " your kind will be hunted and slaughtered like the weak little sheep you are sooner or later"

LOL! We ate you fu%$in pagans for lunch 1500 years ago...we did it once,we can certainly do it again. So fu%$ you, ya fu%$ faced luciferian.

[TyrannoFan]

Why are you guys even arguing against @RideMyBMW, he/she is obviously a fucking idiot, and there's no point in arguing.

[Krandolph17]

WHOA!! That guy down there believes Velikofski's (sic.) "Theory"! Thats... uncanny. Thanks a lot for posting SirNewt.

[ejatz]

@RideMyBMW BWAHAHAHA....

Let me explain some of those points for you right quickly: 2) WTF are you talking about, Venus' orbit is eliptical, like the orbits of all the planets (see Kepler's Laws of Planetary motion). 3) WTF are you talking about, there is a perfectly good (and universally accepted) explanation for that phenomenon. It's called greenhouse effect. 4) WTF are you talking about. Look up Venus's Deuterium/Hydrogen ratio

Oh and for 1)...just...WTF are you talking about?

[RideMyBMW]

Why, if the Moon 1/3 the size of Earth, hasn´t it yet collided with Earth? Doesn´t make sense.

[UbiquitousChe]

@RideMyBMW

The moon is orbiting in the same direction that the earth spins - but the earth spins faster, so the moon can't keep up.

Because the earth spins faster, this causes the tidal bulge caused by the moon to get dragged forward a little.

This in turn off-sets the center of gravity between the two systems a little, and produces a little tug on the moon - speeding it up.

This moves it /further away/.

On a long timescale, the moon will eventually sling-shot away from the earth.

[RideMyBMW]

What Sagan the Pagan conveniently forgets is that if Venus is even HALF as old as Earth, there is : 1)No fu%$in way it should be THAT geologically active. 2)no way to explain its perfectly circular orbit 3)no way to explain its 500 degree celsius surface temp (hottest in the Solar System)4) No way to explain the total absence of water...Velikofski was right.

[GeneralCalculus]

@RideMyBMW Umm.. Why is not thick athmosphere valid explanation? The runaway greenhouse effect. Gasses after all are better medium for absorbing heat than vacuum.

[torontoBluejays87]

@RideMyBMW Yikes, Ignorance is a painful thing to witness

[LaserBeam002]

@RideMyBMW 99% of the people have no idea who Velikofski is but far more people DO know who Carl Sagan is. If you don't like him stop watching his series.

[TheLogicTroll]

@RideMyBMW You sir, are a fucking idiot.

[DawgPro]

When I heard about Velikovsky's story of Jupiter farting a comet... Mouhahahaha. I have found a new expression for telling someone that he's a clown. Hey ! Velikovsky...

Carl, you will be king for eons to come.

This material should be given to the public.

Creative Commons or squarely turn over to the Public Domain.

It has the marvellous quality of - actually - being educational on more than only one subject.

Compare to this, today's TV is garbage.

Thank you for leaving this series available.

[danielsunshinedahl]

Can't see a thing? Must be dinosaurs! =)

[morgandude2]

Yeah..how stupid are default humans?

[gskaloyan]

it is rather silly but they were going about the right idea. They were asking questions and formulating hypothisies. Granted they came to their conclusions far too early and without seeking solid evidence. But they were susing their logic.

[acs328i]

Hmm How could a ball of gas fly through space,to be come venus, I am Curious!

[baalChrist]

Mercury is not as hot as Venus because it is not large enough to keep its 'blanket' of atmosphere through gravitation, and solar winds ripped it away. If Venus is 500C at the surface, and water boils (turns into a gas, which is not a liquid) at 100C.....

[baalChrist]

Haha Sagan the villager, or Sagan the countryman. Wasn't Jebus born in a small town in a provincial backwater of the Roman empire? Hmm, Jasus the Pagan. Tectonics one of many causes of Venus's extra heat, crushed by it's extra atmosphere and without liquid water to aid subduction, Venus has a uniform crust allowing a uniform temperature and no process to allow for a carbon cycle (of which life is a integral part). Radiation of isotopes inside a planet is the cause of geological activity.

[RideMyBMW]

"1)Tectonics one of many causes of Venus's extra heat" - LOL

2)Venus has a uniform crust allowing a uniform temperature - XD!!!!

3)Radiation of isotopes inside a planet is the cause of geological activity. - XD!!! LOL!!!!

What a monkey assed science establishment tool...

[RideMyBMW]

min. 3:39 "Having Enter-TAINING Biblical consequences"

What an arrogant SOB. Catastrophic Science is the proverbial moneky-wrench in Darwinism.

[coozno1977]

LoL and you call Sagan arrogant? Delusion is a powerful thing.

[coozno1977]

This show was made in 1980, more accurate information from Venus was discovered in the 1990s (Magellan Probe) . The very fact that you have an interest in astronomy might very well be thanks to great people like Carl Sagan that brought the wonders of astronomy to the masses in an easy way to understand. Carl Sagan was a great ambassador for the human race. It people like you that bring the worst out of people, the exact opposite message Carl was trying to get through.

[acs328i]

All I can do is Laugh.

[RideMyBMW]

What Sagan the Pagan conveniently forgets is that if Venus is even HALF as old as Earth, there is : 1)No fu%$in way it should be THAT geologically active. 2)no way to explain its perfectly circular orbit 3)no way to explain its 500 degree celsius surface temp (hottest in the Solar System)4) No way to explain the total absence of water...

[minervapractica]

Venus is hot because of the atmosphere and proximity to the sun.

Sagan was a scientist, not a Pagan. I'm sure you mean to call him a heathen, but you would be better off just calling him a heathen; Pagan implies either a polytheistic or decidedly immoral person.

Anyway, nothing the "heathen" says here has anything remotely to do with religion. Keep your drivel in context, please.

[RideMyBMW]

"Venus is hot because of the atmosphere and proximity to the sun. " - miner

Wrong. Venus is hotter than Mercury for Pete`s sake ! Could be atmosphere, yes, but the "green house" effect cannot account for such anomalous conditions.

[KlimeV10]

Why not?

[acs328i]

Someone clings to religion a little too much ^.^

[Sarratt]

time

[RideMyBMW]

min. 2:55 "Catastrophic Science" is all about Life Extinction Events , that, right there, is the proverbial monkey wrench in Evolution´s machinery. Not enough time between cataclysms to account for human evolution. Why do you think Sagan the Pagan tried so hard to silence Emmanuel Velikovski´s "Worlds in Collision" book ?

[jbartz]

thank you so much for the posts. great quality. I love the bit about not suppressing unconventional ideas in search of knowledge

[RJL738]

I wouln't exactly call the logic towards the end common sence.

[tomorosca]

Thats exactly the point Sagan is making, he's saying it's nonscense.

[Ryuzzakii]

Observation: You couldn't see a thing.

Conclusion: Dinosaurs!

Who the hell couldn't disprove that logic!

[Flinchie]

Observation:couldnt see a thing.

Conclusion: Dinosaurs!

[SirNewt]

WHAT?! I was totally planning on posting that same comment when I was putting this video up!

We humans really can be stupid.
