13.8 billion years ago right before the Big Bang, our universe existed within one tiny, compressed atom. But what we know now is that this one atom was not our entire universe.
There were trillions of atoms, all with their own universe inside.
Today, we can only know of our observable universe, but there is far more out there than what meets the eye.
