⬛ DARK MATTER: THE INVISIBLE UNIVERSE
PAGE 1 OF 5 — THE INVISIBLE GLUE
27% OF THE UNIVERSE
IT IS THERE. BUT YOU CANNOT SEE IT.
About 27 percent of the entire universe is made of something that does not emit light, does not absorb light, and barely interacts with ordinary matter, except through gravity. We cannot see it with any telescope. We cannot touch it. No detector has caught a single particle of it yet. Yet scientists are sure it is there, because its gravity holds galaxies together and shapes the entire large-scale structure of the cosmos.
🤔 THE INVISIBLE MAJORITY
Everything you have ever seen, touched, or detected, every star, planet, gas cloud, and black hole, makes up only 5 percent of the universe. Dark matter is five times more abundant than ordinary matter, yet completely invisible to us.
