An interesting fact about lead

[Diver0001]

The lead isn't from the supernova it is just the last element to be created prior to the star's collapse.

No. that would be iron. Lead is created in the collapse.

opps, misread the element. I blame the early morning.

Edit: Also realized that I was mistake about trimix. Helium is obviously the first thing created. note to self: next time make sure brain is engaged before posting.

I tried that note. Doesn't always work.

LOL. Well if I had to wait for that to happen then it would be a long time between posts...

It's ok, Mike. You're still stardust to me.

I'd like to see a star explode!

 

[Diver0001]

So would I.

This one is set on a hair-trigger. Betelgeuse - Wikipedia, the free encyclopedia

With any luck we might see it in our life time.

I would highly appreciate it if this thread didn't dissolve into discussion about contentious science (by which I mean global warming). I'm after a much more positive tone in this thread and I'm afraid I'll have to ask moderators to intervene if it goes that way.

Even threads correct themselves, sometimes

You've got it backwards, life fits the environment, that's all. Change the environment, change the life. Develop half sentient life with some serious conceit and they start to thing that it was made that way for them.

In incomparable Douglas Adams made a brilliant analogy:

Imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in, an interesting hole I find myself in, fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it's still frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.'

* As quoted in Richard Dawkins' Eulogy for Douglas Adams

and

The fact that we live at the bottom of a deep gravity well, on the surface of a gas covered planet going around a nuclear fireball 90 million miles away and think this to be normal is obviously some indication of how skewed our perspective tends to be.

actually, I thought the changes were more fundamental than that .. It's as if the universe were "designed for life" ... I wish I could find that article again

The most I would go with is the weak anthropomorphic principal "conditions that are observed in the universe must allow the observer to exist" (Merriam-Webster's online dictionary) Essentially, if the conditions of the Universe didn't allow for the possibility of life, there wouldn't be anybody to remark upon it...

I'm kinda like'n this one ...

Thank you Jan
