By taking general relativity into higher dimensions, a trio of physicists has proven that a mathematical pattern of ripples ...

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

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...

A new study suggests that a black hole singularity—where time and matter are condensed into infinitely small space—could be a transition to a beginning. This beginning is a white hole—a theoretical ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

MOFFETT FIELD, Calif. – NASA Ames Research Center, Moffett Field, Calif., will broadcast live online on Ustream TV as it welcomes more than 500 guests, including an international cadre of students and ...
