The universe may have a complex geometry — like a doughnut.

Science News reports: "In a universe with an analogous, complex topology, you could travel across the cosmos and end up back where you started."

The universe may have a complex geometry — like a doughnut

Physicists haven’t yet ruled out the possibility that the universe has a complicated topology in which space loops back around on itself.

An interesting article on the time line of the universe.

The Universe passed through many epochs, from free quarks and gluons to stable protons and neutrons to neutral atoms to stars, galaxies, planets, and more. The precise time at which these various epochs occurred, including the (current) dark energy-dominated era, can be pinpointed with precision. Here’s how we know.

The scientific story behind the timeline of our Universe

From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?

I want to believe - but I've heard too many pixie-dust science predictions to just roll over. Prove it to me - show me the math.
