Were all DOOOOMED i tell you - DOOOOOMED :D

Keeeeeeewwwwwwwwl.

I remember reading a ''Popular Science'' book (by John Gribbin I think), and if memory serves, he talked about making Black Holes as a power sourse.

Prolly make a really good hoover as well. ;)

Re: Run for the Hills - Black hole created in lab
 

The new Dyson suckmaster - now with 8 Black holes.

Re: Run for the Hills - Black hole created in lab
 

Fortunately it was only the characteristics of a black hole - if they'd actually created one it would have simply swallowed up the entire lab!

Since I think these particle physicists only make it up as they go along, that probably wouldn't have ben a great loss. :D

I mean how can you take a quark seriously?

Re: Run for the Hills - Black hole created in lab
 

Depends if your'e a Hawkwind fan.

Re: Run for the Hills - Black hole created in lab
 

Atoms I can take, quarks I can take, but strings? Now you're just being silly, there's no way on Earth you can know this stuff!

Re: Run for the Hills - Black hole created in lab
 

I read a short story once where you could buy little 'pet' black holes. You were only supposed to feed them so much.

Of course in the story one person fed his black hole too much and the world was wiped out.

Of course this won't happen in this case....

But it does make you wonder.

Well it makes ME wonder.

Sort of.

Re: Run for the Hills - Black hole created in lab
 

string theory is more like philosophy than science, but the level of mathmatics required to understand it is beyond most people (including me ;) ).

If experiments like the one described and the new one being built by CERN, the Large Hadron Collider, which are both looking for the theoretical 'Higgs bosun', yield results leading to a better understanding of the nature of sub atomic matter, we could really start to get near the 'unified' theory.

Re: Run for the Hills - Black hole created in lab
 

Higgs is very substance of what makes matter (allegedly) and gives it its mass IIRC.

String theory on the other hand i believe relates to gravity and well, goes right over my head - but it essentially the underlying principle behind the unified theory of everything. (Which even Einstein could'nt crack)

My head hurts now. :D

Re: Run for the Hills - Black hole created in lab
 

*whew*! :erm:

Re: Run for the Hills - Black hole created in lab
 

To quote Mike Harding, " its got bu-gg-er all to do with me so i'm going to bed " :D

Re: Run for the Hills - Black hole created in lab
 

absolutely - strings are an attempt to describe all the forms of energy - gravity, radiation, etc as being made of the same thing, just in a different manifestation.

The fact it requires the concept of multiple dimensions, beyond the 4 we are 'used to' is what makes it slightly unbelievable - especially when different proponents of the theory can't agree on how many of these extra dimensions are required.

But when dealing with stuff at the vanishingly small, especially at the level where quantum effects start to make a difference, is incredibly difficult - have a look at some of the pics from the LHC project

- course it would be a lot easier with a naquada generator ;)

Re: Run for the Hills - Black hole created in lab
 

Depends on whether it has Charm or if it's just Strange... :D

Re: Run for the Hills - Black hole created in lab
 

I read the other day there actually that it will almost be impossible to prove string theory one way or the other as they are so small that they would be practically impossible to detect.

Which seems to be to be a damn fine excuse if your trying to prove something.

At least Dark Matter holds some weight (if you get that joke you probably read New Scientist too much :D )

Re: Run for the Hills - Black hole created in lab
 

Hardy har...... ;)

I finished reading this book a couple of months ago. God did it boil my head, but I even managed to understand some of it. :)

From what I remember, the author was driving at the idea that ''Strings'' where about the ''Planck'' (sp?) lenght.

Re: Run for the Hills - Black hole created in lab
 

Planks constant?

Re: Run for the Hills - Black hole created in lab
 

Ahem ;)

Re: Run for the Hills - Black hole created in lab
 

Lol

Re: Run for the Hills - Black hole created in lab
 

Only when it's mass and thus gravity is sufficient to overcome the electrostatic force or strong nuclear force. Not sure which with a black hole.

Although I'm not sure what the difference between a "light" black hole and a normal mass is...

Re: Run for the Hills - Black hole created in lab
 

I just checked the book, and according to the author (on page 140) the planck length is given as 10 -33 centimeters.

In the worlds of the author -

''To get a sense of scale, if we where to magnify an atom to the size of the known universe, the Planck Length would barely etent to the height of a tree''

Re: Run for the Hills - Black hole created in lab
 

I still think this bit is the best...

Its not thought to eh... Inspiring that is.

Re: Run for the Hills - Black hole created in lab
 

I wanna know how they are going to get it out of the accelarater and what they are going to do with it.

Assuming it can be moved or even "seen" anymore.

Re: Run for the Hills - Black hole created in lab
 

well, just as maglev trains are a development of theory, this all may lead to 'antigravity' - what would you do with it? :)

Re: Run for the Hills - Black hole created in lab
 

erm, have these people never even played Half Life? Don't they know that this kinda stuff really should be left well alone?

Re: Run for the Hills - Black hole created in lab
 

Although the Beeb seems to have got its facts a little wrong.

These form a ball of plasma about 300 times hotter than the surface of the Sun.

The temperature of the sun's surface is about 6000C, which gives a result of a mere 1.8 million degrees. I imagine that they mean 300 times hotter than the centre of the sun, which is about 10 million degrees.

Re: Run for the Hills - Black hole created in lab
 

LOL, don't want to create a resonance cascade :erm: ;)

Re: Run for the Hills - Black hole created in lab
 

I tell you, physicists are as thick as two short plancks ;)

http://www.google.co.uk/search?q=planck's+constant - where Google's 'calculator' will tell you what it is.

Some scientists won't be happy 'till they blow everything up :(

'See I TOLD you that's what would happen!!'

Re: Run for the Hills - Black hole created in lab
 

Duh? A black hole is where enough matter is brought together such that the gravitational forces collapse the object in on itself.

So gravity is everything in the formation of a black hole.

I think this has just been creative journalism

Re: Run for the Hills - Black hole created in lab
 

Ah but how do you know that the strong or weak nuclear forces don't play a greater role?

Re: Run for the Hills - Black hole created in lab
 

Unfortunately I don't have the book to hand. It was called THE COLLAPSING UNIVERSE by Isaac Asimov (one of his non-fictional books)

In it he says something like:
But in this case we're not looking at particles, but masses something like 3x our Sun, at which point gravity becomes the overwhelming force nonetheless.

I suggest that anyone who want to understand more on this subject find a copy of Asimov's book, because despite being quite old, it's probably one of the most accesible sources on this subject for those who haven't studied much physics since leaving education.
