This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

Although quantum mechanics and general relatively help explain the universe—at both small and cosmic scales—the two theories are fundamentally incompatible with each other. This has spawn theories ...

Add Yahoo as a preferred source to see more of our stories on Google. A black ball in the center of the screen looks to be falling into a warped spacetime diagram. . Scientists have confirmed, for the ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
