		<description>What if there is no dark matter?

What if all matter is formed from the condensed portions of the overall electromagnetic field, &amp; that this can only occur in the early &amp; extreme conditions at the exit of a singularity plus turbulence? 

What if it  is all a matter of scale? From the sub atomic level to galaxies .

What if there is no such thing as a gravitational field?

What if the only field is the electromagnetic field and that Gravity is really only a term for the distortion  of the  overall electromagnetic field we can call spacetime, by massive objects like stars &amp; planets?

What if the force we call gravitational attraction is due to the natural imbalance of electrons between one piece of matter &amp; another?

This difference only has to be 1 part in 10^40 for there to be the attractive force we mistakenly call gravity.

What if the extra distortion of space time is due to the variations in the density of  spacetime  &amp; not to some mysterious dark matter?

After all energy &amp; matter are equivalent  &amp; all positive energy is attractive.

I know this goes against the grain, but I hope it causes some different directions of thought.

I wanted to give the pot a stir.

		<description>From the articles that I have read and the &#039;shows&#039; that I have seen, I have my doubts about these experiments. I suspect they won&#039;t bare fruit. That being said, we will never know until we try. I really hope the LHC pays off, though.</description>

		<description>Hi Ignoramus:

Well, dark matter theory is a theory. There is experimental evidence that shows that there &lt;em&gt;is&lt;/em&gt; some extra mass out there. The theory is that this matter is made up of the very big (i.e. black holes) and the very small (WIMPs, neutrinos etc). It&#039;s not really a hypothesis as there is indirect experimental evidence that these forms of dark matter DO exist (I gave one example from the galactic halos), so it&#039;s all about planning how to detect these forms of dark matter.

I&#039;m not totally familiar with the details of WIMP theory, but in my mind it is more a theory than a hypothesis. The described WIMP detector takes on a testable model and attempts to prove the theory. So in this case, the theory that a WIMP will hit xenon atoms will be tested. If no collisions are detected, the theory on dark matter will need to be adjusted accordingly.

That&#039;s my take on it anyway :)

Cheers, Ian</description>

		<description>This is an experiment based on one single hypothesis: WIMP&#039;s. Suppose MACHO&#039;s were the answer, then it is a waste of money.
The LHC is not a single hypothesis tool.
Ian, you write &quot;Dark matter is theorized to take on many forms.&quot; Would it not be better to use &quot;Hypothesized&quot; even if it sounds clumsy, because to me the &quot;Theory of WIMPS&quot; does not carry the same level of credibility as say: the &quot;Theory of Evolution&quot;</description>

		<description>By the way, anyone who is fascinated by all of the talk in some UT articles (incl. this one) of the Weak force, the Strong force, the EM force and whatnot would do well to buy and read Bruce A. Schumm&#039;s &#039;Deep Down Things: The Breathtaking Beauty of Particle Physics&#039;.

If you are not a physicist or a mathematician, but have a keen and inquiring mind then it is a book that won&#039;t disappoint. It rises far above the level of mere pop-science, elucidating some of the most wonderful and beautiful aspects of the Standard Model of particle physics in an amazingly clear and readable way. 

There&#039;s even a lot in there for actual physicists - It&#039;s a great &#039;big picture&#039; book for getting your thoughts on the subject organised before diving into the mathematical minutiae. Check it out.

BTW - I&#039;m not associated with the book or author in any way shape or form, other than thinking it was a great read.</description>

&quot;What the hell is that picture of, it looks like two people inside. Is it a giant room with gold mirrors or what? Can someone please explain to me what I am looking at?&quot;

Ain&#039;t it cool? I love scientific instruments such as Super-K and those at the LHC not only for the amazing science, but the fact that they just look science-fictiony and awesome.

On topic - 2.4 million is bargain basement for an experiment like this. I wish I were rich - I&#039;d fund these sorts of things myself. Good luck to &#039;em!</description>

		<description>Its a pic of technicians in the Super Kamiokande neutrino detector in Japan (as mentioned in the text). 

Have a look here: http://en.wikipedia.org/wiki/Super-Kamiokande

Hope that helps :-) Ian</description>
