The Universe is a vast expanse that contains countless wonders, but which some of the greatest minds in physics, even today, still do not understand its secrets. Dark matter and dark energy represent two of the most bewildering enigmas.
These invisible forces account for an overwhelming 95% by mass of the universe's total mass-energy content. Ordinary matter and energy comprise just 5%, as we have come to know.
When we look into the progress that physics has made toward grasping these mysterious things, it becomes clear that many advances have been achieved. The mystery of dark matter and dark energy, however, are every bit as curious and still out of our reach as they once were.
Let's Explore 50 Shocking Facts About Dark Matter and Dark Energy
Around 27% of the cosmos is made up of dark matter.
Since it doesn't emit, absorb, or reflect light, electromagnetic radiation cannot detect it, rendering it invisible.
