Links and Video of the Week (2008/38)

Starting with three LHC links:

And the video How To Read People’s Minds (via Bad Astronomy).

  1. “Teilchen” is not only the German word for “particle”, but also a name for pastries []

Search queries – LHC edition


Welcome to the latest edition of replying to search queries – a special edition about yesterday’s launch of the LHC.

For those who don’t know yet: These search phrases, highlighted in grey, led people here, and I neither shortened nor extended them nor made them up, I just translated the German ones.

LHC function
Check the Wikipedia link above or the link tips at the end, you should find enough information and further links there.

lhc conspiracy theories
Don’t need them, there’s already much nonsense published and searched without them, see the next queries…

lhc end of the world
No. No matter how hard you might wish for it. On the other hand, given these hundreds of comments that piled up at the Astrodicticum Simplex (German) – the large number only caused by unnecessarily scared people, scared by the panic mongers among the media, who’d rather post the same questions over and over again and mostly refuse to read the article itself and/or think a little for themselves – that idea might actually be not that bad at all. ;)

Nostradamus particle accelerator
Get real, Nostradamus, living in the 16th century, couldn’t know what that is. A lot of things can be (and unfortunately is being) interpreted into his gibberish, of course, but, first off, it’s sensible to assume such predictions of the future are impossible anyway – until it can be proven otherwise, but that never worked yet –, and secndly, such interpretations surprisingly only fit well in hindsight…

LHC what energies
Alright, a serious question in between: Each colliding proton has an energy of 7⋅1012 eV (7 TeV), which means the total collision energy is 14 TeV – compared to the 1020 eV during collisions of natural cosmic rays just a little fart. Written out:

         14,000,000,000,000 LHC
100,000,000,000,000,000,000 nature

However, these are just 2.24⋅10–6 Joule (2.24 µJ) in the LHC. Clapping your hands probably releases more energy, just not in such a small space. (The energy needed to power the entire LHC is of course much higher – about 120 MW, estimated 800,000 MWh for 2009 –, since the colliding hadrons have to be accelerated and kept on their circular path in extremely cooled tubes, and this cooling costs a lot too.)

So why all that fear if the LHC experiments are just a weak and small copy – just under controlled conditions with collisions at known places with huge detectors built around them – of what is happening for billions of years everywhere in space, including that li’l solar system of ours?

lhc jesus christ
No, he certainly said nothing about the LHC, he even lived way before Nostradamus. But he’d probably say something like this:
(1) If someone collides one of your hadrons, throw to him the other also. (2) Those however who take great pains replying to all of your questions, honor them by actually reading what they are writing (3) and have written before, (4) for the irrational insistence on your preconceived opiníon long after its falsification is (5) not worthy of human intelligence.

anthroposophy lhc
The combinations these people come up with :roll: – this religious-occult mysticism system really got no place here. Or do you want to take a few Higgs particles – probably no scientists will like the lurid, absurd designation “god particle” – and mix them into the anthroposopers’ homeopathic “medicine”?

Hmm… now how would that be if all this anthroposophy stuff including the advert for a medicine against cold that can currently be found on the schedule booklet of some(?) trains of the Deutsche Bahn1 disappeared in a black hole?

Now that would be something, an “intelligent” black hole that only swallowed that nonsense produced by those panic-mongering, conspiracy-theorizing, mystic dumbers of the masses!

(Yeah, just dreaming…)

Time travel, end of the world, or what?

LHC It seems to be en vogue now to be busy with alleged effects of the new particle collider LHC (Large Hadron Collider) of the CERN which is planned to be completed this May – apart from the “end” of the Mayan calendar which pretendedly either spoil (or prevent) or enjoy us at our Christmas holidays 2012 (a topic even in the current edition of the TV magazine HörZu) – or just lets it start again from its beginning… what’s more realistic, given all those end-of-the-world prophecies that have been wrong all the time?

So recently, for instance, on Golem.de (German) a chaos researcher who probably sees himself as a great scientist found a place for his conspiracy theories and fearmongering about the creation of black holes with the LHC, allegedly threatening to swallow the earth, and the Daily Mail reports about two Russiam mathematicians who believe the particle collisions could create a door to the future, thus allowing time travel.
(via Blog mich am Arsch and JanneWap)

The “bad” thing about all this is just that all energy that the LHC can generate is still way smaller than the energy that are being released all naturally for billions of years when cosmic rays hit the earth’s atmosphere (and also other planets).

Where are the time travelers from the future? Where are the black holes that swallow the earth, why does the earth still exist, with human beings who can think about and blog about such stuff?

Either these time tunnels and black holes don’t exist at all (then the corresponding theory is wrong and the LHC, too, won’t be able to create them) – or they are unobtrusive and not dangerous. So why all that fuss about that?
