This illustration of the cosmic microwave background, heat remaining from the origin of the universe, confirms predictions of inflationary theory. The universe is expanding just as described by Einstein’s theory of gravity. As Dan Vergano writes in National Geographic:
"The strong gravitational wave findings support some of the simplest models of inflation and explain how the mass of the universe first escaped from subatomic size without falling in on itself in its very first moments.
That means that in its very first moments, the entire universe reached a size far, far larger than what is observable or will ever be observable to humanity (the “observable” universe is about 92 billion light-years across).”
Amazing. And all done with a big dish.
