did it die, was it killed

....did somebody not like the answer?

You seem to have the same suspicious mind set as I do Min. Welcome to my club.

Suspicious??

Moi????

There's a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 years - exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star's core.

Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled the effect of temperature fluctuations in the sun's interior. According to the standard view, the temperature of the sun's core is held constant by the opposing pressures of gravity and nuclear fusion. However, Ehrlich believed that slight variations should be possible

This is a new study but I'm sure the theory has been around a while.

There's a dimmer switch inside the sun

did he really say that
is this because hes a physicist and not a realist
or because hes an idiot
or because he thinks that people reading his report are idiots

You're right Marduk, I don't get it! Some days ago you were condemning people's views because they weren't qualified, this guy is qualified.

Well ... obviously YHWH is messing with the dimmer switch every 100,000 years since he messes with everything else, right? That's part of the omnipresent/omnicient thing. More indisputable proof of an invisible hairy man in the sky with a beard and sandals!

Some days ago you were condemning people's views because they weren't qualified, this guy is qualified

and he thinks you're not qualified to understand what drawbacks Nuclear fusion through the proton-proton chain hydrogen to helium converter has in reference to magnitudes of luminescene over a measurable length of time
so he calls it a dimmer switch
is he referring to the sun or our intelligence ?

Depends on his intended audience Marduk, none of us were born knowing about nuclear fusion, neither are we likely to have started our studies at that level.
Everybody makes mistakes, qualified or unqualified. Not far from you are two nuclear research establishments, when I lived in that area when you passed the establishment at Aldermaston, from the road you could see 2 buildings that looked like 'bungalows', each with a very tall chimney. Further along was a very tall chimney with a' bungalow' on top. The 'bungalows' were in fact filters for the chimneys, but in the case of third one the constructors forgot to build the filter first and placed it instead at the top of the chimney!
Every body makes mistakes!

I actually read the article and then the actual paper and based on this conversation none of you apparently did. The author of the article did say dimmer switch but the author of the study did not. And it had nothing to do with dimmness or lumenescence since most stars vary in brightness over regular cycles.

This guy was talking about fluctuations in the rotating core which varied the surface temperature of the sun. While this can manifest as cahnge in brightness, we are more speaking of infrared rather than visible light.

More journalistic spin then. Never trust the media, they are somewhat prone to 'misquoting out of context' - always check out the original source of the story.

Hmmm, what was Hancock's occupation again?


btw the actual research does look interesting Though not, I suspect, pertinent to current climate change. I doubt the sun is causing mass deforestation in Brazil or Indonesia, for example

Is there anybody in this forum who believes that GW is a natural phenomena or am I on my own?

You're not alone. I think we're going through a natural cycle.

I agree with both of you. The cycle of warming and cooling has been proven.

It has been shown, without doubt, that we are contributing to that warming since the beginning of the Industrial Revolution. But to what extent we are contributing is a heated issue.

It's natural....but we are making it worse.

HOWEVER. Blaming everything on oil consumption is a politically correct way to try to put the onus on developed countries. Every night, five of the world's 6 billion people start cooking fires and those all release by- products as well.
