I don't pretend to understand how the Universe was formed, with all the attendant questions that tend to give me the willies. This story is fascinating, about astronomers on Hawaii apparently glimpsing some of the first stars ever formed. That's a look back in time of 13 billion years, when the Universe was about 500 million years old.
One day, we'll see the Big Bang itself. And that's when my poor little head will explode.
