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 ...

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 ...

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 ...

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 ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

Einstein's general theory of relativity, published in 1915, relates spacetime curvature to matter distribution, leading to the Schwarzschild solution describing a black hole. The Schwarzschild ...

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 ...

Andrew Svesko receives funding the United Kingdom Research and Innovation (UKRI) via the Science and Technology Facilities Council (STFC) grant ST/X000753/1. Antonia Micol Frassino receives funding ...

Singularity University (SU) — the new academic institution with the goal of preparing the next generation of leaders to address “humanity’s grand challenges” — today announced the selection of 40 ...

The propagator W(t0,t1)(g,h) for the wave equation in a given space–time takes initial data (g(x),h(x)) on a Cauchy surface {(t,x) : t = t0} and evaluates the solution (u(t1,x),∂tu(t1,x)) at other ...
