Default Article] Dark matter may be undetectable

Dark matter may be undetectable
Super-WIMPs might hide ninety percent of the universe.
8 July 2003

Researchers going underground to detect signs of the elusive dark matter
thought to far outweigh normal matter in the Universe might be wasting
their time, a team of physicists is suggesting.

Jonathan Feng and colleagues at the University of California at Irvine
propose that dark matter, which is believed to constitute around 90% of
all the matter in the Universe, is hiding in the form of particles
called super-WIMPs that would evade all conventional dark-matter
searches1.

Currently, one of the leading suspects for the inexplicable
gravitational pull that stars and galaxies experience are WIMPs - weakly
interacting massive particles. These are heavy relative to the protons
and neutrons that make up atoms, and so have strong gravitational
effects. Otherwise they hardly influence normal matter at all.

In the hope of detecting very rare collisions between WIMPs and normal
particles, physicists in Europe and the USA have set up detectors far
beneath the Earth's surface, shielded from cosmic rays.

Such efforts might prove fruitless, warns Feng's team. Their proposed
super-WIMPs interact so weakly as to be effectively invisible.
"Super-WIMPs are impossible to discover directly and escape all indirect
detection experiments," they conclude.

Comment:
when your calculation is wrong, make up an undetectable particle or
undetectable matter. Have they forgotten that the universe isn't closed,
that we don't need to discover the extra mass and that the Big Bang
theory is based on constantly shifting sands.

Just like the color force that makes quarks undetectable. "What? No quarks
come out? Then their binding force must increase without limit, to make the
unobservable!"
