How a sudden event 15 billion years ago shaped our entire universe
In short: Trace the origins of everything in this animation. It explores the Big Bang Theory, examining the groundbreaking discoveries and observations that explain how the universe and life itself began.
Scientists believe the universe began suddenly between 10 and 15 billion years ago under conditions of extreme heat. This animation delves into the evidence supporting this theory, such as the measured amounts of helium and other chemical elements that match theoretical calculations.
The video also covers the 1920s discovery that galaxies are moving away from one another, proving the universe is expanding. Finally, it highlights the 1965 discovery of cosmic microwave background radiation—the energy left over from the Big Bang—which earned its discoverers a Nobel prize.
