Completed sentence:
Two astronomers accidentally discovered background radiation, which is evidence of universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is uniform. By observing this today, we can see what the universe looked like 13,700,000,000 years ago.
(Discovered by Penzias and Wilson — the cosmic microwave background is nearly uniform at about 2.725 K, with tiny anisotropies that reveal early structure.)
