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 ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for ...

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 ...

Susskind, a physics professor at Stanford, and Cabannas, a former MIT math professor, offer an overview of Einstein’s theory of general relativity in this survey for specialists, the fourth volume of ...

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 ...
