Traveling to Before the Big Bang
Take the entire known Universe, all 93 billion light-years of it. All two trillion galaxies, every star, every planet, every black hole, every quasar, every speck of dust, and you. Then squeeze it all down until it's smaller than a proton. Now, you've got yourself a singularity.
The kind of singularity that was the beginning of our Universe. And that’s where you’re headed. The moment before the Big Bang.
