I love it

^Qwerty^

Nah it was Sun, and I was on the **** end of the stick with that one. We had multiple CPU panics on Ex500's. In fact, I had two E4500's in cluster which suffered a 'hit' about once every two weeks, I once lost the 2nd of the pair, whilst the first was rebooting. How unlucky was that ??

IIRC, the cache was manufactured by Big Blue and was non-error correcting. Major design foo-bar of some years that one. Still, it's easier to blame something you can't see.

Can you imagine the sheer size? The incredible mass? The unbelievable length of the risk assessment form for this project?

OllyK

Indeed, more chance of that creating a spontaneous black hole!

Could or would we have been allowed to build such a device in the UK?

I already came up with that theory in post 113 though a bit more concisely

Yeah I thought so. I have since blamed every sh1tty ksh I've written and screwed up on cosmic rays! If it's good enough for Sun ....

Geezer, you're post might be a bit more reassuring with the addition of some greek letters

Think they might mean 'nanometres'

Give them a break, it's the 'New' Scientist. They've only just finished University.

I have to say that having watched those two programmes on BBC4, the impression I got was similar to that of Mrs Leslie, who is nobody's fool.

She reckoned that all those eminent scientists spend ages trying to understand what it is all about, and then they suddenly think of a possible answer, apply loads and loads of mathematics to it all and then come to the conclusion that the latest theory would only work if there was the presence of another unknown substance which is ever so difficult to see, if you were ever in its presence. So they thought up the name "Dark Matter", Good one that!!

Now they are going to try to find it and if they can prove the "Higgs Boson" then all will be well!

Olly, can you explain how they can identify what they are seeing from those traces in a cloud chamber after they have done a bit of whizzing around the cyclotron and smashed it all together in the collider? They couldn't anyway!

Are you able to prove all those answers you gave me in your previous post?

Mrs Leslie says they seem to be long on theory but short on facts, and that they dont really understand what the outcome of their actions might be.

Do you honestly think that I thought the piece of superdense matter which they say was what exploded in the Big Bang weighed a couple of Kilo's? Either you are exaggerating what I say or you must think I am so ignorant not to know the real sort of weight of such material. How heavy must such a tiny physical size of mass be if it gave rise to the entire universe? Give me some credit will you!

Incidentally, what is the weight of a critical mass of material to set off a nuclear weapon, and we all know the damage that can do. Wouldn't it be awful if this imitation big bang converted the collider et al into something really fissile?

Geezer

It's SN's fault, it pastes in ok, then when you post it ruins it! Of course, you pedants know what I meant

I'm no scientist but was/am interested in Astronomy.

I know that sometimes black holes are created when a star dies, sometimes a star just grows and grows until it becomes a red supergiant (like Beltegeuse in Orion) and will explode leaving a gaseous Nebula.

Sometimes this will leave its core which becomes a White Dwarf (Not the bloody TV programme before anyone starts) it can collapse even further creating a Neutron Star - this is literally around the size of the Isle of Wight, and is that dense from what i remember a thimble full would weigh 50000 tons.

The next evolution of a Neutron star maybe a black hole which has gravity so high and is so dense not even light can escape (where have i heard that before)

I may be wrong in some of the above as i'm recalling stuff from 20 years ago. but there you go.

OllyK

We could, but we'd still be 30 or 40 years off firing it

OllyK

Ahhh - somebody else that doesn't understand what a scientific theory is! Must be a family thing.

Sure, when you acknowledge that drawing comparisons between smashing a couple of protons together is not the same thing as a singulaity containing all the mass in the universe, you can't get much further a field in terms of scale.

Plutonium or Uranium, and which isotope?

Do you know how much a proton weighs?

rumour has it we already have, imigrants jump in the french end and pop up in blighty. no need for fussing with sneaking onto lorrys and getting across the water

Leslie

Thank you for such a polite reply!

You just did not read my posts properly or you did not understand what I was saying.

Les

OllyK

Ok....

That's just from the first page. So tell me again how you aren't trying to compare smashing a couple of protons together with the big bang that came from a singularity containing all the mass/energy in the universe.

Start comparing apples with apples and I'll start giving you some credit. Oh and learn the difference between scientific hypothesis and scientific theory please!

I love it, any machine that has Large and collider in it is alright by me, and the fact that Hadron looks a bit like Hardon is even better.

So, if it works, what does it do for us, will it benefit mankind and move us forward or will it give dusty bearded blokes something to Mass Debate about

Ok, if it ***** up we dissapear as quickly as we alledgedly appeared, so what, we wont know about it, big deal, do we actually matter, will anyone miss us, ok we dont exist but at least the Economic situation is dealt with. We need to take these gambles, otherwise we just stay still, plus it isnt really a gamle is it, its some particles underground, in a big blender, remember when people used to say Locomotives would tear the earth in half, its the same idea.

I really hope they conjure some weird stuff up, like at the start of Half Life, that would be cool, not for this **** knocker though,

The whole things puts me in mind of this little exchange from a famous 1980's film

Dr. Egon Spengler: There's something very important I forgot to tell you.
Dr. Peter Venkman: What?
Dr. Egon Spengler: Don't cross the streams.
Dr. Peter Venkman: Why?
Dr. Egon Spengler: It would be bad.
Dr. Peter Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?
Dr. Egon Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.
Dr Ray Stantz: Total protonic reversal.
Dr. Peter Venkman: Right. That's bad. Okay. All right. Important safety tip. Thanks, Egon.

Not off the top of my head but you will have to be more specific. I rekon my mums 'compact' is probably about 900kgs

I wish you would stop ordering me about as if you were a schoolteacher. I can't help imagining you jumping up and down with steam coming out of your ears just because someone has had the temerity to disagree with your personal views, especially when it comes to religion or science. If you want to disagree with me thats fine by me, you are as entitled to your beliefs as I am. I do find it a bit peculiar when you are so rude and overbearing about it all. It is almost as though you are a fundamentalist with regard to scientists and their ideas and that they cannot possible make a human mistake. Your play on words above about hypothesis and theory is purely semantics and means nothing. And what on earth was the point in asking me what kind of fissile material they would use in a nuclear weapon? What are they so busy producing in their centrifuges in the Middle East then?

The point I was making is perfectly clear and there is no point in going over it again.

I really hope that my fears are groundless and that no further serious effects stem from the experiment on Wednesday. I shall be the first to admit that my worries were wrong and be delighted that they were. But I still feel that going so close to the Big Bang scenario could produce problems that are not envisaged by those carrying out the experiment.

You have to admit from my posts that I am prepared to accept that the Big Bang may have happened even though it has not been totally proved. If it did, the energy generated in order to start off our Universe from such a small piece of superdense material as we are told is of a size which is impossible to encompass. That is why I have worries about this action on Wednesday.

Incidentally, are they going to fire off one proton and aim to hit another with it?

The accelerated particles travel at almost the speed of light (99.999999 etc %). Amazing! It's a worry though as who knows what will really happen, they've only got theory to go on as far as guessing what might happen ...
