The universe spans 93 billion light-years and continues expanding at an accelerating rate into the unknown.
The universe encompasses all matter, energy, space, and time that has ever existed. It began 13.8 billion years ago with the Big Bang — a singular expansion event that created the framework of reality — and has been expanding and cooling ever since.
Only 5% of the universe is ordinary visible matter. The remaining 95% is comprised of forces we cannot yet directly observe: dark matter (27%), which holds galaxies together through gravity, and dark energy (68%), a mysterious force that accelerates the universe's expansion.
Celestial bodies locked in stellar orbit. Some are rocky worlds like Earth; others are colossal gas giants.
