FULL TITLE: Earth and Venus are the Same Size, so Why Doesn’t Venus Have a Magnetosphere? Maybe it Didn’t Get Smashed Hard Enough

[NohSpinZone]

The global warming nutjobs often use Venus as the model for the catastrophic effects of runaway global warming. As if they’ve been there and understand how Venus got to be as hot as it is.

The full title is very amusing.

Men are from Mars, Women are from Venus. Let’s get liquored up and go to Venus.

"Maybe it Didn’t Get Smashed Hard Enough"

[null and void]

We’re told the earth’s atmosphere would be stripped away by the solar wind if the earth’s magnetosphere did not shield it.

Yet Venus, being closer to the sun, has a more intense solar wind flux, no protective magnetosphere, and a very thick atmosphere.

What’s up with that???

Does Hillary have a magnetosphere? I’m pretty sure she’s been smashed hard enough.

No iron, no magnetism........................

We'll be fine visiting, if we brush up on our Hungarian!

The Earth has an iron core that is about 1.5X larger than it should be. The theory is that the Earth was impacted by a Mars sized object. The iron cores combined, but other material ejected, and formed the Moon.

Without this impact, we would not have the strong magnetosphere, to protect us, nor would we have the Moon that stabilizes the Earth's rotation. The Earth would be a very chaotic place, and it's likely life would not have evolved past a biologic sludge.

That is why I find it ridiculous that people keep calling exoplanets, 'Earth-like', because they are not. In order for a planet to be truly 'Earth-like', it MUST have what the Earth received in the massive collision that created the Moon. And if you calculate the odds of that, it makes the Earth a MUCH rarer commodity.

can I still insert a Uranus joke?

[familyop]

The core materials are different between the two.

[I want the USA back]

Stupid question. Assumes that planets of similar size must have the same attribute regarding the magnetic field.
The real question is why do scientists think they have an explanation for everything?

[Political Junkie Too]

Earth has a magnetosphere because, long before the dinosaurs roamed the earth there were Monstermagnets. They died off and became the magnetosphere just like dinosaurs died off and became fossil fuels.

Gawd, this is too easy.

I’ll wait for other posters...

Lack of a magnetosphere was one of Velikovsky’s predictions in the 1950s, among many other correct predictions about the physical nature of Venus. It had absolutely nothing to do with some ‘collision’, but rather the origin of the planet.

[JimRed]

Worlds in Collision (Immanuel Velikovsky, 1950) gives an interesting theory on the origin and history of Venus. It relates to historical events on Earth 3500+/- years ago as well.

Venus

Earth

No comparison.

a series of accretion events

So that means the earth was only 5000 miles in diameter once. I'd like someone to tell me what the composition of the layers was then. Were the supposed plates moving then too.
