Quantum foam

Here's what you would see if you were to gaze deeper and deeper into empty space until out of nothing, something suddenly appears.

If you magnify spacetime down to its tiniest scales, it might be like staring into the frothy foam atop a pint of beer.

Theory suggests that empty space is filled with enormous energy, but according to a new proposal, this energy may be hidden because its effects cancel at the tiniest scales.

Of a much simpler and a complete-invariant quantum foam.

Quantum physics shows that there is no such thing as "nothing." Even in a vacuum, particles can blink into and out of existence.

Sequel of the preceding post The Warped Science of Interstellar (4/6) In november 2014, the Hollywood blockbuster and science-fiction movie Interstellar was released on screens and much mediatic excitation arose about it. This is the fifth of a series of 6 posts devoted to the analysis of some of the scientific aspects of the film, […]

It's creative, beautiful, and mind-blowing.

A recent study of gamma-ray bursts finds that spacetime is smoother on the quantum scale than expected.
