The way massive objects of the universe bend and distort gravity and light indicates to scientists about the existence of dark matter. The way large objects move about in the universe (velocity) also is a factor pushing towards the probability of much more mass than is visible.

Dark matter provides the gravity and weight in galaxies, which would fall apart if all they had was what is visible to scientists via their various instruments.

Particle detectors and other dark matter detecting projects prove the universal interest in dark matter:

1. From Italy, a particle detector named XENON1T is hunting for dark matter with an ultra-low background.
2. From South Dakota, the Large Underground Xenon Dark-Matter Experiment (LUX) is hunting for weakly interacting massive particles (WIMP).
3. IceCube Neutrino Observatory is situated under Antarctica’s ice, hunting for sterile neutrinos.

Apart from dark matter, the universe is full of energy, most of which is dark energy.

New data shows that the universe is not running out of energy like previous theories claimed, but is actually expanding at an accelerated rate.
