Creationist vs Scientist Live Debate

[Mardoo]

Luckily for me, I only have a hand full of these nut jobs in my family tree. I take joy in letting them handle my stony, stony-iron, chondrite and tektite collection.

Ooooo, can I see!

Nahhh... no nova. The sun is G type main sequence. You don't get novas until you up up in the blue giant range.

In 3-4 billion years or so the sun will stop burning hydrogen at its core. The core will shrink to a point where it begins burning helium. At that point the sun will drop off the main sequence and become a red giant. Later it will shed its outer layers as a spectacular planetary nebula before the helium runs out and the core is not big enough to start burning carbon. It ends up as a white (then black) dwarf.

You don't go nova unless the core is heavy enough to start burning carbon to silicone then silicone into iron. Around 20 solar masses is the limit if I remember correctly.

Science is wonderful.

:lol: ah yes, I should have known it was G type main sequence.

What's a super nova vs nova then.

Then can you tell me about black holes please. And I don't mean where the sun don't shine

 

[Airgead]

Actually I was slightly wrong...the nucleosynthesis is hydrogen->helium->carbon->neon->oxygen->silicone->iron. I left out a few steps.

A supernova is where the core of a massive star undergoes collapse (or other wierd processes like pair instability) and goes foom.

A nova is usually where a compact object (like a neutron star or white dwarf) collects material on its surface which undergoes fusion and explodes.

The key difference is that in a nova the object survives. In a supernova it doesn't.

Supanova on the other hand is a comic book convention in Sydney.

And black holes are cool.

And black holes are cool.

How do you measure the temperature of a black hole ?

 

[Airgead]

Strangely enough you can.... a black hole is a perfect black body radiator. You can measure its temperature very accurately indeed from its spectrum.

A black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic radiation called black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition.

Cheers
Dave

Science - FTW!

Two of my brothers, myself and my father have to sleep in bed with a slated head board, and we all have to sleep holding the slats,
I hadn't thought much about it, and put it down to something quirky that had passed down from father to son.
My wife has mentioned it a few times that I look like I am scared of falling out of bed, then I read a piece by the late Carl Sagan about the "Falling Dream" which we all have, his theory was that when we were tree dwellers and built our nests high in the trees that is where the falling dream originated and made us hold on to a secure branch.
I would like to know how many of you have to, or are more comfortable, holding on to a slatted bed head, or as I have told my Dad
his side of the family are lagging behind on the evolutionary ladder.

 

[Ducatiboy stu]

The only reason I grabbed the head board was so I didnt get dragged out of bed to go to school in.

 

[Bridges]

I thought they were called head boards as you generally bang your head on them whilst on the job...
Or maybe I have a big head...

 

[wide eyed and legless]

If you can bang your head more than six times your a legend

While reading buzzfeed tonight I came across this post on what creationists views are on dinosaurs. They have an actual dinosaur museum, and believe dinosaurs were on Noah's ark. OMG. Or should I say Oh there god

A good doco on evolution is the BBC series Walking with Caveman. Explains how we evolved from apes due to climate factors etc.

They say one of the evolutionary leaps we took was due to us eating bone marrow from dead animals after lions had eaten a kill and left the remains. The bone marrow contained protien which helped our brains to grow.

You can download it from the torrent sites.

 

[Ducatiboy stu]

The stupidity is breathtaking.....whats worse is some of these fools go on to become world leaders.

Then again, Pharoh's beleived cats where higher beings.....and anyone who has a cat would sometimes think that the cat actually believes it is a higher being

Carefull...you will upset the raw food vego mob

Which brings me to another story where I offended another group. I was talking to some girl at the drive-in movies during the intermission. Somehow she mentioned that she was a vegetarian and I said "oh, I don't think I could be a vegetarian" she replied "why not?" I replied "I love eating dead cows too much". Needless to say it was the end of the conversation. Not even my parting "what, was it something I said?" could charm her back.

Angus Grant: offending demographics way before comedians made it cool.

On balance, its predominantly atheist countries who enjoy a better standard of living. This contrasts sharply with the backward brutal, cultural quagmires still under the theocratic jackboot.

This tends to nullify the persistent bleating of religious types that society would collapse into a murderous orgy without the fickle hand of god and his impossible to follow prohibitions.

Expressed beautifully.


Years ago I worked with a guy who believed Earth was only 6000 years old. When I asked him about carbon dating he told me that it was made up by scientists.

Watch some of this from about 10 minutes.

Show me the evidence.

I want a batmonkeyfish fossil

Not isolated

@manticle: come on man, I don't wear glasses. Besides that, the video brings a back a few memories. He he

I only offend demographics that choose to be a demographic. Oh wait.....
