Dark Matter Day
Less than 5 percent of the total mass and energy in the universe is the stuff we know about: like stars, planets, galaxies, and gases.
Dark matter makes up about 85 percent of the total mass of the universe, and about a quarter (26.8 percent) of the universe’s total mass and energy. Almost 70 percent (68.3 percent) of the universe’s mass and energy is composed of dark energy, another big mystery to scientists that is causing the accelerated expansion of the universe.
On and around October 31, 2017, the world celebrated the hunt for dark matter. Local events planned by institutions and individuals around the planet explored its mysteries, and highlight the experiments that could bring us closer to solving them.
