Detection of gravitational waves from colliding black holes has been confirmed, proving a critical Einstein theory.
An ancient supernova that was serendipitously captured in four Hubble space telescope images thanks to a naturally occurring cosmic magnifying lens has reappeared, as astronomers predicted.
Scientists are taking initial steps in a long-term effort to learn as much as they can about gravitational waves -- mysterious undulations in the fabric of space-time that have so far evaded clear detection.
Tonight at 7 p.m. ET, The Perimeter Institute will be hosting a special lecture by theoretical physicist Neil Turok, who will explain why, actually, our universe has the simplest geometry of anything we know. Streamed LIVE.
How does time stop everything from happening at once? What mechanism drives time forward, but not backward? Continue reading →
Through the analysis of light from distant galactic clusters, astronomers have detected a mysterious signal that they're having a hard time explaining. Continue reading →
In an effort to visualize what a future starship may look like, NASA physicist Sonny White and space artist Mark Rademaker have teamed up to create the 'IXS Enterprise.'
Physicists have tried searching for time travelers on the Internet. But they didn't find any.
