NOVA Universe Revealed: Big Bang
Aired Nov 24, 2021at 9PM·55m
The Big Bang is when many think the universe started and time itself began. But what clues can we discover about this ultimate genesis of everything? And can we ever know what existed before the Universe’s birthday? With stunning animation based on space telescope images, NOVA explores infant galaxies filled with violent blue stars that formed just a few hundred million years after the Big Bang. Before that—before the coming of visible light itself—stretch the “cosmic Dark Ages.” But scientists haven’t stopped there; instead, they’ve come up with an incredible theory for what happened billionths of a billionth of a second from the universe’s birth. If they’re right, we’re on the brink of understanding more than we could ever have hoped about our cosmic origins.
