Will the Big Bang test end the world on Wednesday?

[Faun]

^^lolz you know why these things are called experiments ?

There is a difference between theoretical value and practical happening. Lots of factors affect my mighty sire.

Work out some numerical from university physics and then their practical approximation examples, the results varies significantly.

^^ Never forget Erwin Schrödinger my good sir! He developed the Wave equation on paper alone. The pen/paper combo is mightier than the laboratory! And do not embarrass me by calling me sire. I do not believe in titles. No one does these days.

Why dont we stop wacking our heads over a thing which might never achieve consensus in reality, in theory may be it will, or it already has.

Ease yourself out, Its wednesday. The world has not ended. At least as yet.

Take a look at this interesting article on LHD, and stay chilled out.

And it won't kill anyone whenever it happens. Aren't the words of the world's best scientists, CERN, UN Several Courts of law enough? I had even calculated the energy the collision will emit it was something like 9.something x10^21 Joules. Then, I calculated the energy that 6.022x10^23 particles/molecules/atoms (1 mole) of helium would absorb(using the Specific Heat Capacity of Helium(which would be kept at 2 K(-271degreeC)). I found it to be about 8.somethingx10^27ish Joules. And they've got large Helium tanks on that LHC. This means that extra energy released by the simulation of Big Bang can be taken care of. That ends it for the big-final-blast theories. As for those pesky black holes, they will be so small(category-microblackholes) that they won't even have an event horizon big enough to do any damage. And they can't grow if they've got nothing to attract!

+1 to everything, ++1 to blackholes.

Wouldn't the black hole cease being one the moment it absorbs enough matter to have its density decreased by several times ? Wouldn't gravity also aid to this increase in density ?

Many other things were discovered by chance too, remember. Here people are not doing it theoretically, its practical time. Penicillin was a chance discovery, hopefully it was a good serendipity. And countless many which never make it to the books were may be a mournful history of someones unfortunate fate. You know not every person is lucky in the flock.

So there is always a slim chance of things occurring not the usual way. Lets hope everything turn out to be calm and we get to know more rather than lost into unknown. For I believe that science can make us reach new heights or mar our future.

May be you are much more experienced in physics field, so its good that its creating a buzz among everyone.

Gravity shouldn't have any effect on density IMO

I think the force exerted by earth's gravity can help bring unstability to the pico sized black hole.

Think about it, blackholes are always the biggest baddies around when they occur naturally. But couldn't a much greater force destabilise it and result in its expansion ?

Guys I've some updates for you..........

There's just one snag with all that - it's cobblers. All the good, interesting stuff from the LHC - the Higgs deiton, the dark matter, the possibly planet-gobbling black hole dimensional portal threat and/or universe-buster runaway strangelet or monopole soup plagues, dessert topping apocalypses etc - none of that's on offer today. All of these excellent possibilities require the LHC boffins to actually collide some hadrons - well, duh. The clue's in the name. But they aren't ready for that yet.

What's happening today is the inaugural, gentle bowling of some initial protons around the entire 27-km subterranean ultrachilled superconductor magno-track. That's your lot.

In coming months the underground Alpine boffinry chiefs, once happy that they have hadrons whipping round the big ring properly in one direction, will fire up the opposing stream going the other way.

Only then, once the two unprecedentedly puissant particle cannons are reliably ripping out clips of protons on full auto both clockwise and anticlockwise, will the real fun begin. Only then will the boffins begin to seriously meddle with the very fabric of the universe, as they possibly rashly cross the streams of the two colossal energy guns, ramming protons into one another at almost light speed. Thus far, we are told only that this will happen "by the end of the year".

^^However I doubt that creating micro black holes will be possible, if so it may be quite unpredictable.

Here is some to digest:
*curious.astro.cornell.edu/question.php?number=219

will give u an idea. I guess today is wasted on researching on this black hole thngy, anyway it will be a nice ride.

OMIGOSH!!! I'm alive!!! I'm alive!!! Miracle!!! God forgave me for my sins!!! I'm alive!!!


Ah well, madness apart; the result, whatever of the experiment, will take us a lot closer to understanding the Universe. And as Stephen Hawking himself said, the LHC is crucial if we are to save human race from wiping out. And, the innate human nature has always fueled such prospects.

If sources are to be believed, there are 0.1% chances that a micro-black-hole may form. That amount too is obtained when we take multi-dimensionl calculations into account; which may not affect us after all. Thats very less probability but nevertheless important in scientific terms.

Though, the black hole wont stand a chance against us as within 10^(-3) yoctoseconds, it will vaporise; due to the well theorised Hawking Radiations.

Thats is the faintest possibility. The capabilities of the LHC are far too low for creating something at that scale; and even if it forms; we have no danger. Ergo, you can sleep soundly in your bed, or for that matter in your wife's.
The cosmic radiations that hit the earth's atmosphere are much more powerful than the LHC's capacities. If LHC is to be feared, then, micro-black-holes may have formed and escaped, w/o even being detected. And the phenomenon may be much more pronounced, with several hundred back holes forming each second. But we know that nothing of such a scale has happened and harmed us, hence LHC is far from dangerous.

Huh? Sorry.. This is what I call overflow of emotional tranquility.

ADDED: And BTW, the actual collision is to take place in October, probably 21st. We'll have media all over it, again when the time comes. This one was just a test, accererating particles w/o colliding. AFAIK.

IronMan.

nice read, a concept of time travel too(yet not feasible):
*cosmology.berkeley.edu/Education/BHfaq.html#top

Hawking radiations are based on sudden creation of energy by particle and antiparticle at the event horizon (the place where after you cant escape black hole if its static one).

Normally these vacuum fluctuations (the particle and antiparticle) are bound to collapse again to reset the energy conservation. But at even horizon one antiparticle may get inside black hole and sucked up while other will reach to the outer space.

For black hole there exists white hole, mathematically. Nature love symmetry so does mathematical equations. A white hole will throw anything out fro its even horizon.

So the combination of black hole and white hole can give rise to system known as worm hole. You get sucked up in black hole and then popped out of conjoined white hole. But your survival during the transition is a question unbelievable, considering the amount of blue shift in the radiations coming with you. But thats too a concept which is not verified practically.

So may be this Hadron will tell us about something crucial or something bad.

Here you go:
*news.bbc.co.uk/2/hi/science/nature/7604293.stm
BBC has confirmed that the TEST run of the LHC has been successfully completed
The actual collision will be done in October, whose results may be out by the end of the year.
Looks like this thread will be flooded with "doomsday paranoid freaks" by then

 

[IronManForever]

@T159. We may die but we will probably be in shape when we are thrown out of white hole. The same symmetry principle. But, Id still like to believe that we'll live.
Though there are alternate theories that deny the existence of any white-hole itself. They tend to say that all mass goe into the black hole and it goes on becoming denser... something like that...

I guess my source was not exaggerating too much in the previous post...........

Some more cookies from the link by wisecrab:

"We will be looking at what the Universe was made of billionths of a second after the Big Bang. That is amazing, that really is fantastic."

we need a superhero intervention to save us...lolz

The latest astronomical observations suggest ordinary matter - such as the galaxies, gas, stars and planets - makes up just 4% of the Universe.

The rest is dark matter (23%) and dark energy (73%). Physicists think the LHC could provide clues about the nature of this mysterious "stuff".

We are still at the null...lolz. This dark thing fascinates me and everyone else...dark night, dark matter and now dark energy.

While working on the LHC's predecessor, a machine called the Large-Electron Positron Collider, engineers found two beer bottles wedged into the beam pipe - a deliberate, one-off act of sabotage.

A beer boozed blackhole...lolz

But your survival during the transition is a question unbelievable, considering the amount of blue shift in the radiations coming with you. But thats too a concept which is not verified practically.

According to modern Science, if you cross the event horizon of a black hole, you will face a slow down of time(not perceptible to you), and then will face Spaghettification(technical term for getting ripped to shreds) as the part of your body closer to the center will be attracted more. So there is no way that the white hole can get you out with your head in the right place. Life is sure to perish. Moreover, White Holes are mere results of the tendency of humans to find a symmetrical pattern(Yes I study Psychology too, a hobby).

I think to warp ahead in space, we need to know more about the other 8 dimensions(starting with time). I support the theory that if v>c, properties of matter in one of these other dimensions must be affected(Hopefully time). But anyway, that's offtopic.

Oh, and creating black holes is possible! Scientists have already made black holes using particle accelerators before(didn't you know?). The theory is to make it more dense than it can handle and it will start collapsing and sucking. The black holes created by particle accelerators till date were really small ones. They are known as microblackholes. But, they are not strong enough to last for some time or to exist outside the Particle Accelerator.

By the way, it's nice to know someone who can understand my physics mumbo-jumbo(my friends call me mad because of it). Are you a University student? or a scientist?

@alexander
But what all they could make was not actually a real blackhole....at least what i got from web resources...they well similar in thing that both needed string theory to explain. More of a nuclear force black hole than gravitational ones.

I believe in philosophy. There is always room. World is strange and for that matter you dont even know what your 80% grey matter actually do. There is a great deal of dark knowledge inside our brain, may be some thing that can give us an answer to many things. But people have a tendency to peek outside instead of looking unto own self.

I believe in Buddha's wisdom. Thought my religion is different. There are many things one can learn.

I used to learn from reference books as a hobby, not that i was preparing to crack some exams. Still have University Physics, Morrison Boyd, FInar, JD Lee, H C Verma, Stout and Green, Ebbing etc. Biology was my prime interest, but somehow due to circumstances ended up pursuing BE.

There was a recent incident when I came to know how horrible the basic facilities has become. A doctor now only wants money, even at the life of a poor thing. But internet helped me to save that life. First use of internet in my entire life that saved someone Its great to have it for free and people in forum/web helping each other, sharing and caring.

Sometime I think this virtual world is much better than the real world which is more like a flawed design. No wonder people will call you strange if you behave normally, cause world is too fcuked up now to appreciate normal person.

Another tid-bit from Hitboxx provided link:;

the data extracted may take another decade or two to unravel and interpret

Hope world won't change much till we interpret it...lolz
