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 ...

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

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 ...

A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e., points where the laws of physics break down. Identifying how ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

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