I wonder what the heck everybody's so worried about. It is my firm belief that if the world gets sucked up in a black hole, we'll just simply emerge at the other end - and FINALLY our curiosity will be satisfied regarding the question: Where does everything end up that enters a black hole anyway? Probable answer, already provided by the latest Indiana Jones movie: Inter-dimensional travel!

So... end of the world aye...

Glorious, always hated that neighbours dog.

So... if I go in last but head first. Does that officially mean that I would have the biggest dong on the [micro] planet.

This gets better and better.

I'm just waiting for my birthday in 2012. The day the Myan's think the world's going to end, and the day that some scientists believe something like an "electromagnetic pole shift" my occur on earth, literally moving the earths equator to god knows where.

the day that some scientists believe something like an "electromagnetic pole shift" my occur on earth, literally moving the earths equator to god knows where.

erm... the equator is the simply the plane that is perpendicular to the Earth's axis of rotation and contains the planet's centre of mass, (0-degrees latitude); it has nothing to do with the earth's magnetic polarity. The magnetic poles poles aren't even in the same place as the axial poles about which the earth rotates (true north and true south) at the moment.

Rotation of the Earth is what generates the Earth's magnetic field (well, rotation of the Earth's iron core) but the magnetic field doesn't effect the Earth's rotation itself, so our axis of rotation and hence equator will remain where they are.

What will change is the axis of the field through the Earth. Weather patterns may change due to charged particles flowing around the Earth differently and 'equatorial climates' may exist in places away from the geometric equator for a time; but like I said the Earth's rotation will remain as-is.

Have they announced a proper date for starting the collisions in LHC yet?

Last thing I read was that they were fighting with many problems and the start was postponed to the end of this year.

Bah, lets worry about the real things, such as economies slowly going to hell, petrol becoming increasingly expensive and just about everything going up in price.

Stuff that! Gets me depressed

Black hole all the way. Far less agony, both for us and the planet.

Anyway yes, the end is near IMHO, but asteroids or black holes aren't needed: human kind is more than enough for this task.

[mattxr 9]

Im sure the Aliens we see more and more oftern will come to save us... lol

also 2029 April 13 my BD the comment that will have a near miss then calculated 4/5 years later it will pass the earth a second time and will smash stright into us.

From the BBC Website:

Cern lab goes 'colder than space'  

By Paul Rincon

Science reporter, BBC News  

Superconducting magnets are cooled down using liquid helium

A vast physics experiment built in a tunnel below the French-Swiss border is fast becoming one of the coolest places in the Universe.

The Large Hadron Collider is entering the final stages of being lowered to a temperature of 1.9 Kelvin (-271C; -456F) - colder than deep space.

The LHC has thousands of magnets which will be maintained in this frigid condition using liquid helium.

The magnets are arranged in a ring that runs for 27km through the giant tunnel.

 Exchanging a single component which today is cold, is like bringing it back from the Moon

Roberto Saban, Cern

Once the LHC is operational, two particle beams - usually consisting of protons accelerated to high energies - will be fired down pipes running through the magnets. These beams will then travel in opposite directions around the main ring at close to the speed of light.

At allotted points along the tunnel, the beams will cross paths, smashing into one another with cataclysmic force. Scientists hope to see new particles in the debris of these collisions, revealing fundamental new insights into the nature of the cosmos and how it came into being.

The most powerful physics experiment ever built, the LHC will re-create the conditions just after the Big Bang.

Currently, six out of the LHC's eight sectors are between 4.5 and 1.9 Kelvin, though all sectors of the machine have been down to 1.9 Kelvin at some stage over the last few months.

By comparison, the temperature in remote regions of outer space is about 2.7 Kelvin (-270C; -454F).

The CMS detector will search for the Higgs boson - the so-called "God particle"

Roberto Saban, the LHC's head of hardware commissioning, said that in order to obtain high magnetic fields without consuming too much power, the magnets were required to be "superconducting".

This is the property, exhibited by some materials at very low temperatures, to channel electrical current with zero resistance and very little power loss.

Helium exhibits spectacular properties at 2.2 Kelvin - becoming "superfluid". This allows it to conduct heat very rapidly, making it an extremely efficient refrigerant.

No particle physics facility on this scale has ever operated at such low temperatures. But, so far, the hardware was performing as predicted, Roberto Saban explained.

"We have a very systematic process for the commissioning of this machine, based on very carefully designed procedures prepared with experience we have gathered on prototypes."

He added: "Our motto is: no short cuts... exchanging a single component which today is cold, is like bringing it back from the Moon. It takes about three to four weeks to warm it up. Then it takes one or two weeks to exchange. Then it needs three to six weeks to cool down again.

"So, you see, it is three months if we make a mistake."

Two sectors of the LHC are currently not cold enough for testing to proceed. Electronics that control the cryogenic systems in these sectors are being moved to an area where they will be better shielded against particles that shoot out of the machine during collisions.

Closing the circle

One sector of the ring is being run as if the LHC was operational and carrying a beam. This is so that crews can de-bug software and hardware and gain experience of running operating cycles.

The LHC's magnets must also undergo electrical testing. Each sector of the machine contains about 200 electrical circuits. Each circuit may consist of as many as 154 magnets or as few as one.

They are being tested for their ability to handle very high currents - up to 12,000 Amps .

The Alice experiment recreates the conditions just after the Big Bang

"We power each circuit, making sure it goes to its design current. But above all, we are verifying that all the protection systems around it - which are there to detect an eventual quench - are operating as expected," said Roberto Saban.

A quench occurs when some part of the magnet starts to heat up, becoming resistant to electrical current. Engineers have built in a recovery system to detect these quenches before they affect the magnetic field bending particles around the ring and shut off the circulating beams.

The machine's cool-down should take another two weeks to complete, provided no serious problems are found. Electrical testing of the magnets may take another couple of weeks.

Before the LHC is "switched on" for the first time, the proton beams have to be boosted to high energies in a chain of particle accelerators called the injectors.

Once the machine is cold, operators will inject beams into the main ring, threading them through each independent sector of the LHC until they close the circle.

A timing, or synchronisation, system is used to ensure each of these sectors behaves as if they were a single machine.

When the LHC is switched on it will operate at an energy of five trillion electron-volts. It will then be shut down for the winter, so that the magnets can be "trained" to handle a beam run at seven trillion electron-volts.

Oh boy!!!  How many volts?

Interesting read dale

On a different note, one thing that really worries me are the Far-right Christian radicals who seek to expand Israel, start a war with Iran, and destroy the Temple Mount all in high hopes of bringing back the Messiah (Jesus). Yep, there have always been extremist groups in all of the world's religions but check out how many high-ranking U.S government officials support these guys.

 The Rapture

Personally I think any politician aligned with any apocolyptic group should be outright banned to run for office.

Do us a favour mate and dont derail this thread, start another one please.

Ta.

[froggyluv 2130]

Sorry- guess I lost track what this thread was about upon seeing your "End of the world?" title

Frog out

*dusts the cob webs off*

yeah I keep hearing the association of 2012 and the "end of the world" a lot. Thats only what, 4 years away? Hey WAIT!!! I think thats when ill have enough money to buy that cool Illudiom "Pew36" Explosive Space Modulator!!!!

I did watch a very respected documentry that said the chances were so slim you can sleep safely on it.

Things to worry about-

Super volcanoes.

Giant Asteroids. (The first inkling we may know of one hitting us is the shock wave 5 seconds before it does)!

A worldwide killer virus.

Sleep safe.

eV, not V... different measure to be exact, eV's are used to measure energy, just like joules - at a very low scale, though, since we're talking about single electrons here. Of course, at those energies the currencies are quite... "nice" also.

Although oddly enough, the same unit is quite commonly used as a measure of mass also in particle physics (via E=mc^2)... what a fun subject.

Cheers for putting that up, wouldn't have prolly noticed it otherwise.

One eV's 1.602*10^-19 Joules, it's mostly used to describe low energy systems such as those that exhibit quantum mechanical effects.

The reason it's called an electron volt is because it's the energy that an electron gains when it's accelerated by a potential difference of 1 Volt from the relation E = qV (E = energy in Joules, V = potential difference in Volts, q = charge of the particle in Coulombs). For an electron q = 1.602*10^-19 Coulombs hence E = 1.602*10^-19 when V = 1 Volt.

Since the LHC will mostly be accelerating protons which also have a charge of 1.602*10^-19 Coulombs, creating a stream of protons that has an energy of 7*10^12 eV would require a potential of a 7*10^12 Volts. eV and V describing the particle beam are pretty much interchangeable; though given the nature of the experiment, there are probably some quantum effects that I've ignored that may change that relation (it's been about a decade since I did any Quantum Mechanics so I don't really recall what other relations may govern the energy of the beam).

That said though, the potential generated by the magnetic field in the LHC is not necessarily of a similar magnitude to the voltage describing the power supply to the experiment, which is what dale appears to have in mind; since the magnets pretty much make a big transformer.

Is it wrong that I keep reading it as "large hardon collider?"

Freud would have a field day.

[dale0404 5]

Lots of words I dont understand!!

I bet it still hurts if you touch the 'wires'!!

And, Kooky, that made me laugh mate.

If it is the end of the world maybe something better would replace it? Too many political, economical issues worldwide as of now IMO.
