[glowpurple]Scientists: Dark matter exists[/glowpurple]
(SPACE.com) -- New observations of a great big cosmic collision provide the best evidence yet that invisible and mysterious dark matter really does exist.
The collision, between two huge clusters of galaxies, is the "most energetic cosmic event, besides the Big Bang, that we know about," said Maxim Markevitch of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.
The impact split normal matter and dark matter apart, rendering the dark matter's gravitational presence observable.

Nobody knows where all that gravity comes from, so scientists say there must be some invisible stuff out there, which they call dark matter. Its presence is indirectly supported by many observations. Given what's known, this is the makeup of the universe:
5 percent normal matter
25 percent dark matter
70 percent dark energy
Dark energy is an even more mysterious phenomenon, a force of some sort that beats out gravity and is causing the universe to expand at an ever-faster pace.
