How physics can help us make sense of multiverse madness

If you're a fan of science fiction films, you'll likely be familiar with the idea of alternate universes—hypothetical planes of existence with different versions of ourselves. As far from reality as it sounds, it is a question ...

Alan Guth on new insights into the 'Big Bang'

Earlier this week, scientists announced that a telescope observing faint echoes of the so-called "Big Bang" had found evidence of the universe's nearly instantaneous expansion from a mere dot into a dense ball containing ...

GR20/Amaldi10: Space-time is not the same for everyone

Before the Big Bang, space-time as we know it did not exist. So how was it born? The process of creating normal space-time from an earlier state dominated by quantum gravity has been studied for years by theorists at the ...

Visualizing spin angular momentum in water waves

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown. This will help to provide new insights into very different wave ...

Quantum Sensor Developed by LSU Researcher Breaks New Limits

(PhysOrg.com) -- Researchers at Louisiana State University have invented an optical sensor that surpasses a quantum limit to sensitivity previously believed to be unbeatable. The breakthrough has a broad array of applications, ...

Look at Mie! Team tests century-old calculations

Calculations are fine, but seeing is believing. That's the thought behind a new paper by Rice University students who decided to put to the test calculations made more than a century ago.

Probing the dark side of the universe

Advancing into the next frontier in astrophysics and cosmology depends on our ability to detect the presence of a particular type of wave in space, a primordial gravitational wave. Much like ripples moving across a pond, ...
