A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

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 ...

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 ...

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

It feels so obvious that time moves forward that questioning it can seem almost pointless.

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...

Want to visit an interesting exoplanet, or dip dangerously close to a black hole? It is not impossible – there’s no law of physics that forbids humans from traveling through space – but it’s just ...

Before a beginners’ physics class at St. Louis’ Washington University, Assistant Professor Edward Lambe plugged in an electric device that shot pennies at a metal disk a few feet away. The pennies ...
