Large Hadron Collider creates 'mini Big Bang' with lead ions

The reaction created temperatures a million times hotter than the centre of the Sun, which have not been reached since the first billionths of a second following the Big Bang.
This was expected to cause atomic particles such as protons and neutrons to melt, producing a "soup" of matter in a state previously unseen on Earth.
This process took place in a safe, controlled environment generating incredibly hot and dense subatomic fireballs with temperatures of over ten trillion degrees – a million times hotter than the centre of the Sun."

The latest experiment at CERN went ahead despite warnings by a group called Heavy Ion Alert that it could trigger a catastrophic chain reaction that might destroy the Earth.
LHC scientists say the claim is nonsense.

So does that mean a mini Jesus saved a mini planet from itself? Was there little dogs running around a little earth for billions of little years? Hah. I could go on for days with this one. Cool though.

Thats it, dont you see?

Time shift again.. Expect more "Tasmania is on the wrong side of Australia!" or "New zealand is always shaped like a football" posts.

Every time they run the LHC time shifts. They're trying to find the Perfect Earth Reality.

I wonder how I died... did I suffer or did I just blink out... Be nice if they could expand the temporal bubble to involve a camera that recorded how the earth just died..

As a person whom has a background in physics I always follow what is going on over at CERN and the LHC.

I have to say that although this is ground breaking for us here on earth, this temperature has certainly occurred in the universe at other times other than the so called big bang.

What I'm getting at here is our use of language to describe what we see is very telling of our attitude. As a civilisation that has yet to reach type 1, to say that we have created something that has only happened once before at the big bang is arrogant and frankly stupid.

The drake equation (an equation that equates intelligent civilisations within our galaxy) estimates there are around 10'000 intelligent civilisations in the Milky Way, some younger than we are and some a lot older and everything in between...

I think we should be more humble about our discoveries and realise that we are actually on catch up and really quite unknowledgeable in the greater scheme of things.

That is not to say that we shouldn't feel excited about our discoveries, just we should be more modest.

BTW Just a quick edit to add that the risk of strangelets is a real risk. A chain reaction is possible with these kinds of energies. My personal view is we should look to build a collider in space, this would prevent any such risks.

Two questions:
1. Why are strangelets more dangerous?

2. What measuring device do they use that can withstand these extreme temperatures/

I wish I had a physics brain, but unfortunately I fall a little short.

ill answer the first question. strangelets are theoretical particles which make up something known as "strange matter". if a particle is large enough, and it touches any nucleus of another particle, then that nucleus will turn to strange matter, and then continue on as long as it remains in contact with anything. its only a theory at the moment though that these even exist.

Ok for starters the Big Bang is a THEORY...why are they so certain that they have the answers regarding the big bang taking place and the timescales at which there were certain temperatures??

I'm all for expanding our knowledge but it really annoys me wheyn people presume to know things then pass it onto people as if its true, when they have no idea...

Grrrr
