21 Mind-Blowing Space Facts That Put Everything Into Perspective

  • A sweeping view of Earth shows vast cloud formations stretching across the ocean from space.
  • Brian WantsTruth There's a star out there which is spinning at 42,900 rpm (that's one rotation every 1.3 millisecond). If you stood on the equator, you would be whipping around at about 24% of the speed of light.
  • TheCosmicTravelers The fact that the universe itself is undergoing intrinsic expansion - it is not expanding into anything
  • detectiveriggsboson coal and oil might be some of the most rare things in the universe
  • ZylonBane That in a few hundred billion years, the expansion of the universe and consequent red- shifting will push the cosmic microwave background radiation below the detectable noise floor, and all non- gravitationally bound galaxies so far away from each other that they exit their respective observable universes.
  • tboy160 As unfathomably large the universe is, the scales are even more insane microscopically.
  • Local-Warming You are made of stardust, but so is garbage
  • arrowtron The Andromeda Galaxy is ~2.5 million light years from earth, and is visible to the n ked eye. That means the light you see when you look at it is 2.5 million years old, and nothing - nothing - in 2.5 million years broke that moment of light you are seeing. It travelled 14,700,000,000,000,000,000 miles without ever being interrupted until you stood in its way.
  • madlabdog A black hole that has mass of earth would be size of a pea.
  • wickedparadigm That all the other planets of our solar system fit between the earth and the moon.
  • noshoes77 Rogue planets are terrifying to me, and they are fascinating.
  • The International Space Station orbits above Earth with sunlight illuminating the planet’s curved horizon.
  • spornerama You are the universe experiencing itself
  • IsC... That the speed of light has a finite speed that's takes time to traverse the universe. So, hypothetically some alien in a galaxy 66 Million Light years away, with an incredibly powerful telescope, could point at Earth and see dinosaurs walking on the planet. And also witness their demise.
  • quickblur It would take you more energy to fall into the sun than to escape the solar system.
  • Robin_Banks101 There are more trees on earth than there are stars in the Milky Way. This fact boggles my mind but also kind of makes the whole galaxy feel a little smaller.
  • Darthmichael12 There are more moves in the game of chess than there are atoms in the entire universe.
  • under_ice Physics at the smallest scales. Planck length scales. Crazy stuff happening down there.
  • Centmo The human brain is volumetrically the most complex known structure in the Universe.
  • mtnviewguy The Universal expanse is so large, that it is incomprehensible to man. That fact that many Earthly religions think we're the only life in the Universe is equally incomprehensible.
  • damadmetz Either the universe continues on forever, or it doesn't. Both options are weird.
  • Olympicmessiah That there is no end to the astonishment. Whether you're a casual observer, lifelong astronomer, astrophysicist to the most famous and intellectual minds in the field throughout history. There is always something else that breeds fascination. A new discovery that makes you feel like you did as a child when your interest was first piqued. The more we learn, the less we find out we actually know.
  • Guy_PCS Quantum entanglement is a real, experimentally verified physical phenomenon where paired particles remain connected, sharing a single quantum state regardless of the distance separating them.
  • The Moon’s rugged surface emerges from darkness, lit softly along its curved edge.
