Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

Travel far enough in the universe and you could end up back where you began. Measurements from the Planck space observatory have shown that the universe might be shaped like a sphere rather than a ...

Space Matter is a weekly column that delves into space science and the mechanics of spaceflight. From the latest discoveries in the universe around us to the fits and starts of rocket test flights, ...

Bayesian model averaging is a procedure to obtain parameter constraints that account for the uncertainty about the correct cosmological model. We use recent cosmological observations and Bayesian ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the ...

So while the measurement is consistent with a flat universe, it is possible that the universe is closed and finite. However, the constraints are tight and if the universe is finite it must be very, ...

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 ...

The following is an excerpt from The Gravity of Math: How Geometry Rules the Universe by Steve Nadis and Shing-Tung Yau. Copyright 2024. Available from Basic Books ...

(via SciShow Space) Can geometry predict the future? Cosmologists think the overall curvature of universe can tell us secrets about how it will eventually end. Related Topics: Universe, Geometry, ...
