July 2 (WTN)- What we can observe in our sky planets, stars gas, dust, galaxies, nebulae asteroids, meteors, and more   is a small fraction of what Exists. Bright matter, the visible stuff of the universe, forms only about a sixth of its mass. What forms the rest and how do we know it’s there?

Scientists know be more out there than meets the eye because the unseen substance has gravity and appears to be holding together  the parts of the universe that we can see galaxies in particular, because  the unseen matter does not emit radiation, scientists call it dark matter.

Believed to constitute about 95 percent of the universe’s total mass, dark matter and dark energy may comprise unfathomable numbers of tiny subatomic particles. Candidates for dark matter include cold dark matter(CDM) sluggish elementary particles, weakly interacting massive particles (WIMPS) heavy hypothetical particles  that rarely interact with other matter, massive compact halo objects (MACHOS) know object such as planets ,neutron stars and white dwarfs that are presumed to be in the halos of galaxies.
