Black holes and magnets.

Perhaps dark matter doesnt exist. Scientists are wrong and their calculation is bogus on computing how much mass there is out there.

I'm currently campaigning for the lattice structure of our universe being electromagnetically driven. What looks like mass is just inbuilt structure of our wobbly, non-Newtonian spacetime. Magnetic monopoles fired during the big bang then traveled in nonlinear, entangled directions causing both an energy gradient hard limit, and a slight shape to stabilize within the pocket of 5th-Dimensional fluid. As an added bonus it answers the monopole issue (The remaining magnetic filaments prevent monopoles within the localized fields), as well as Baryon Asymmetry (the bow shock of non-relativistic travel for monopoles would act more upon antimatter).

Am I sciencing right?

More than one (admittedly crazy looking) guy talking on his own in a room, which is always a source of science to be taken with a pinch of salt.

Work up the math and you'll probably win a Nobel Prize

Lister jump-started the second big bang with jump-leads from Starbug, you twonk.

Unlikely.  That's the sort of thing they double-check before they build the giant multimillion dollar detectors.

All you stars out there need to stay bright and shining because you don't want to END UP LIKE ZOIDBERG!  BWAAAHHH!! *runs off crying*

You wouldn't be the first person to think that.

The trendy coffee shop here in Sudbury makes a Dark Matter roast and sends it to all the collaboration meetings at the neutrino/dark matter mine.

Yep. However it's hard to come up with an alternative gravitational theory that is consistent with the many different effects that Dark Matter explains - not just galactic rotation rates, but cluster collisions, large-scale structures in the universe, and its evolution over time. It's even harder to come up with one that's physically motivated: MOND, for example, is completely arbitrary "curve fitting".

In fact I saw one piece by a staunch opponent of Dark Matter and advocate for an additional field (which is just another way of saying "include another term in the equations for gravity") who went back and forth with other physicists and eventually admitted that, as a quantum field theory, their additional field required an associated particle... and the properties of that quantum particle looked an awful lot like a candidate for Dark Matter...

So basically, the viable theories at this point boil down to:

- An undescribed particle that interacts only through gravity, which is definitely something we know can exist

- A "fifth force" that isn't gravity, and has an associated particle that does not interact through the existing forces (EM, Weak nuclear, strong nuclear) but does interact with things that have mass

At that point it's largely a matter of taste whether you want to call that thing a force in its own right or an additional term in the the gravitational equations.
