Hadron Collider - String Theory

If some pieces are missing they are assumed to have gone to another dimension!

I thought the idea behind Dark Matter was that it could be part of both, if not had to be part of both. Hazy memory of watching Horizon following some guys under a hillside, may have been CERN but I seem to remember Wales for some reason, and they had been searching for Dark Matter for 15 years. They said that Dark Matter passes through everything, and they hadn't captured it yet, and assumed that it was part of both anti-matter and matter. It was a long time ago though.

Depends entirely if you are talking hot, cold or warm dark matter. (no I am not joking).

Basically means they don't know shit are are trying to put terms to things they are yet to understand. So far the only measured recording of "dark matter" has been gravitational pull. Which supposedly is actually and affect of antimatter too.......

Hadron Collider (and all its successors) are scary but exciting concepts. Especially when you think of the maths behind black hole theory.......sometimes proving something right is not always the best option

This is the best explanation of the multi-dimensional universe I've seen... The writer (Rob Bryanton) has a superb blog if yer in to this stuff.

that hurt my head a little bit, but was the most understandable one I've seen.

I love the LHC's scientific method too, can't remember where I read it, but basically they plan to just smash shit at higher and higher energies until they get some answers.

The Theory extrapolates till the 42nd dimension where it's revealed that all other dimensions are actually ideas inside Douglas Adam's brain.

, what about lukewarm

That clears up why they call it String Theory.

An alternative being?

Just to confuse matters, astrophysicists are not only looking for Dark Matter but also for Dark Energy which is quite different. Current estimates are that Dark Energy contains 73% of the energy in the Universe.

Dark Matter by comparison (if it exists at all) contains over 80% of the total mass of the Universe.

Dark Energy is evidenced by Vacuum Energy derived from the Cosmological Constant, where particles pop in and out of existence in the vacuum of space. Alternatively Dark Energy comes from Scalar Fields but TBH I'm lost at this point.

One thing which is missing from observations is anti-matter. Some think Dark Matter contains it but others think anti-matter was mostly annihilated shortly after the Big Bang. Why? Short answer - quantum fluctuations.

[Winston001]

The arguments for Dark Energy and Dark Matter are based upon the observed gravitational attractions of galaxies wheeling around each other. Conventional physics requires all of this stuff to eventually smash together - but it isn't.

Instead the Universe is expanding and more surprising, that expansion is accelerating. So something must be pushing it.

Dark Matter explains the gravitational movements we see within the bubbles in the Universe. The unseen mass provides the extra gravity required to explain the amount of attraction.

Dark Energy by contrast explains why the Universe is expanding and accelerating apart - something which requires heaps of energy.

But just to confuse matters - what if time in our local galaxy was slowing down? Everything outside would speed up and appear to accelerate. That could yet be the simple answer to a puzzle that has us stumped.

I'm assuming that they're talking about an Infinite Improbability Drive .

I do wonder if a temporary change of element state and/or composition takes place... enough to excite the element(s) (maybe more than 1 elemental reaction required based on a composition/type/velocity/mass etc... of neighbouring elements) into such a frenzy that human beings are unable to detect the "change", or measure the velocity... yet.

LOL. This thread is too geeky. When God disappeared in the puff of smoke because of the BabelFish, all information about the universe was lost 42!

The mega-geeks have calculated that 99% of everything was annihilated in the big bangs matter/anti-matter explosion, leaving us with the matter that exists today and the occasional tiny spec of anti-matter. This is a matter based universe (instead of an anti-matter universe) because there was a tiny variation in the amount of matter/anti-matter at the beginning of everything.

The question I have is, where did all that energy from the 99% of stuff being annihilated go??

Lorentz (sp....don't have time to google) theorized that while a small change will affect something else on a massive scale (aka butterfly effect), that perhaps it would go to such a scale that it would almost go unnoticed.
In one of his experiments he actually proved it (sort of) as he punched what was thought to be a chaotic string into a "computer" (HP's weather calculator from recall) and its final resultant had a value that came out as unknown. The resultant should have come out on screen - but the value for some unknown reason went well above the maximum amount of digits the computer could handle. When he looked at all previous results.....turns out they all had this problem.....but had been dis-guarded as "bugs" or "errors". But held more value than the rest of the data.......
It was human logic to remove the data that didn't match.

We still haven't learn't lessons though - ever wonder why we always have el nino weather cycles and "freak" storms?????
Lorentz's work still is not taught in most classes. Yet many things were explained by Lorentz, Mandlebrot and many others decades ago. And proven........

but alas I digress once again.
Collider - awesome smashy thing that will tell us whats in between the parts in atoms. Very handy because when you thing of the fact that there is not much in an atom, and yet they have a perceived volume........we could all fall apart / disappear if we are not too careful Thank goodness for charge.
Non-linear science is awesome

heh... I removed the butterfly effect from my last post... funny to see it appear here ( ).

I much prefer the notion of non-linear science, kind of explains why the brainiacs with large chemistry sets can't proove things beyond a doubt in some cases... you may get close, but you'll never know for sure... I kinda hope that loss of mass that they're looking to reconcile is just light. That'd crack me up.
