Every smartphone navigation fix, every precision agriculture pass, and every aircraft approach depends on atomic clocks ...

New claims challenge inconsistencies in one of the foundational principles of physics. What could this mean for geophysics ...

Researchers have now found a solution to Einstein's equations that allows for an alternative. When a star collapses at the end of its life, it doesn't necessarily have to end in a black hole, but can ...

Under that reasoning, certain exotic structures of spacetime called closed timelike curves may be real—and they may allow a ...

Albert Einstein's famous relativity quote, "When you are courting a nice girl an hour seems like a second. When you sit on a ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past ...

Researchers propose that extra-dimensional spacetime torsion prevents black holes from fully evaporating, leaving remnants that preserve quantum information. Credit: SciTechDaily.com A new theoretical ...
