The majority of the energy in our Universe went completely undiscovered until the late 1990s, and scientists still don't know what it is. Only 5% of the Universe, in terms of energy, is made out of things we're familiar with and understand: protons, neutrons, electrons, photons, neutrinos, black holes and even gravitational waves. Of the remainder, 27% is dark matter and 68% ⁠— the largest amount ⁠— is in the form of a new, mysterious substance: dark energy.

Dark energy was first revealed observationally: by examining the light from ultra-distant signals like supernovae. With measurements of both distance and redshift, scientists concluded that the Universe couldn't just be made of matter and radiation, but needed a new form of energy that would change the fate of our Universe. Here's why, more than 20 years later, it's still the biggest unsolved problem of them all.
