The cosmos may have something in common with a doughnut. In addition to their fried, sugary goodness, doughnuts are known for their shape, or in mathematical terms, their topology. In a universe with ...

Penrose's idea of a conformal cyclic cosmology hypothesizes that our Universe arose from a pre-existing Universe that would leave imprints on our cosmos today. This is a fascinating and imaginative ...

The universe may be flat, but could still be shaped like a doughnut, weird patterns in leftover light from the Big Bang suggest. When you purchase through links on our site, we may earn an affiliate ...

Here’s what you’ll learn when you read this story: Mathematical evidence indicates that our universe is flat, but it could be infinitely big, as well. You can figure out if an object is flat with a ...

13.8 billion years ago, the Big Bang occurred. The Universe was filled with matter, antimatter, radiation, and existed in an ultra-hot, ultra-dense, but expanding-and-cooling state. By today, the ...

TACC's Frontera supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structures in the universe. Example Lyman-α forest spectra from ...
