Yep, it helps me sleep at night.

And the knowledge that the abusive client may cease to exist at any moment, owing to the sudden non-existence of the entire universe, makes putting up with the bugger that much easier...

[i got bored on the trip to wellington to see the surgeon yesterday] so if anyone here could explain it to me....

and i really want to learn about anti-matter, i'm assuming the only way to store anti-matter would be in an electro-magnetic feild...otherwise it will be in contact with matter and umm yeah we would cease to exist depending on the amount of anti matter ofcourse

Achieving absolute zero is theoretically impossible in practice. The no motion thing is not 'quite' correct. From wikipedia; "One would like to define it as the temperature at which all motion ceases, but even at absolute zero some motion remains due to the requirements of quantum mechanics. Alternate definitions are that absolute zero is the temperature at which no further energy can be extracted from a physical body."

umm. In order to reduce something to absolute zero you would have to remove all its energy. Since any form of energy would produce some form of radiation.

The explosion of antimatter is called antimatter annihilation. Fermilab and Cern currently produce anti-protons. I think for CERN its anti-hydrogen at 1 kelvin.

Penn state are trying to work on producing antimatter space engines using proton annihilation. Thats seems interesting.

:spudwave:

that makes sense

thats a risky idea...

There is new state of matter that has been discovered called Bose-Einstein condensate. It forms at only a few billionths of a degree above absolute zero, and one of the leading universities that is studying these extreme cold temperatures is, of course, Otago. There is some information on the research at http://www.physics.otago.ac.nz/resea...becbasics.html

The Bose-Einstein condensation was first achieved on June 5 1995 at the university of Colorado in USA where a temperature of 170 billionths of a degree above absolute zero was achieved. Otago physicists have managed to get even colder.

Did someone say it was cold in Otago?

Nothing is impossible.

Often wonder why the quest for absolute zero, and what they hope to achieve.
Where they just sitting around till someone said “Hey, lets freeze the fuck out of something” and it grew from there?
Powered on by the dream to have the biggest ice-cream headache ever?
I like the unified field theory tho, so I’m no better.

**ducatilover** · 29th January 2006, 20:59

if nothing is impossible then its possible that nothing is possible therefore contradicting itself!

**Ixion** · 29th January 2006, 21:00

No it's not, and no it's not and no it doesn't

**ducatilover** · 29th January 2006, 21:02

that sounds logical. or are you talking about that random impossible/possible thingy i just said?

**Cookie** · 29th January 2006, 21:15

You are deeper than I once thought ducatilover

**ducatilover** · 29th January 2006, 21:25

i just posted this in loptihgad.

and i did write it

Quote:
"nothing is impossible."

takeing that quote lets think about it.....
so does that mean if nothing is impossible, then it means that it is possible that nothing is possible? because then its a dead end. but if nothing is possible how can it also be possible? is nothing some warped theory that is "probable but we cannot discuss the likely hood of these circumstances" material? but how can we have a name for nothing? as theoretically it doesnt exist but then again it does exist by the fact it has been named. then we come to think how is it possible to name the absence of being [or matter]? because therefore nothing exists merely by the fact of the discovery of its non-existance. but how can nothing exist? it isnt matter and has no mass, cannot be seen, heard, touched, or smelt. even the "sixth sense" cannot find nothing but it can find the absence of something. but alas the absence of something is not nothing as there may be another something in its place. but if nothing is impossible it means that all matter is surrrounded by nothing and all small gaps are full of nothing. but how do you fill something with nothing? simply you remove all existance or matter in side of this something. but to do that creates a vacum sucking the sides or walls of this something towards its exit for matter. thus leaving a flat something with a lack of nothing. but... according to the nothing is impossible theory this piece or literature does not exist, therefore classifying it as nothing. but how could you read nothing? you cant but yet you may still be reading this document. there was another contradiction as its impossible to read nonexistance. but it is possible according to the quote.... so the famous quote
Quote:
"to be or not to be?"

can now be answered with the quote
Quote:
"nothing is impossible",

just be and not be at the same time as nothing exists as i have already theorised by the fact of its non existance.
