HERE’S THE INTERESTING PART

Georges Lemaitre looked at celestial equations and boldly claimed the entirety of space was aggressively stretching outward from a single dense point. At first, even the brightest minds completely dismissed his theory as mathematically absurd. He ultimately forced the scientific establishment to accept that the universe is basically a giant, ongoing thermodynamic explosion.
