Why Space and Time Might Be an Illusion

This past fall, the world of physics celebrated the 100th anniversary of Albert Einstein's general theory of relativity, which forms the foundation of our modern understanding of the force of gravity. Einstein's creation has been the ultimate antidote to a blasé, seen-it-all attitude that sometimes …

A 5-dimensional black hole could break the laws of physics as we know them

The simulation has suggested that if our Universe is made up of five or more dimensions — something that scientists have struggled to confirm or disprove — Einstein's general theory of relativity, the foundation of modern physics, would be wrong.<p>In other words, five-dimensional black holes would …

What Is The Universe Expanding Into? (Synopsis)

“Mathematicians deal with possible worlds, with an infinite number of logically consistent systems. Observers explore the one particular world we …

Does the discovery of gravitational waves foretell the end of physics?

It took us 100 years to confirm the last big puzzle of Einstein’s theory of relativity. On Feb. 11, scientists announced that they have detected gravitational waves, which are created when two accelerating masses generate “ripples” in the curvature of spacetime—just like frolicking children on a …

Entanglement: Gravity's long-distance connection

When Albert Einstein scoffed at a “spooky” long-distance connection between particles, he wasn’t thinking about his general theory of …

Is The Multiverse A Scientific Theory?

Anyone can come up with a theory, which in common parlance, simply means “an idea for how something works.” But in order to be a <i>scientific</i> theory, you have to do a lot more. In particular, any new scientific theory has to look at the current framework of science, including the current leading/best …

Using general relativity to magnify the cosmos

One of the most powerful known magnifying lenses isn’t found on Earth. The lens is built from stars, gas and dark matter and lies about 4 billion …

Dark Energy May Be Distorting Our View of Gravitational Waves

Waves traveling through expanding space-time should look different than waves traveling through static space-time.<p>Dark energy may be distorting long-sought gravitational wave signals from distant sources in the universe, according to a paper posted to the arXiv pre-print server by astrophysicists …

Physicists must accept that some things are unknowable

The Universe may be truly infinite, but our understanding of it never will be. Here’s why.<p><i>“To know that we know what we know, and to know that we do</i> …

Special Report: Gravity’s Century

In 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all …

Neutrinos, antimatter, and science as a holistic detective agency

‘Holistic’ is a much abused word. Like ‘quantum’ and ‘paradigm’, it is beloved of snake-oil sellers of many types. But some kind of interconnectedness forms a key part of science’s defence against spurious results and crackpots. Two new scientific results got me thinking this week<p>Deep in the ice, …
