What Triggered the Big Bang? It's Complicated
In the beginning, there was a question mark. All else followed. The end. We've all heard of the Big Bang theory (I'm talking about the cosmological model, not the TV show), but it's important to understand what that theory is and what it's not. Let me take this opportunity to be precisely, abundantly, emphatically, ridiculously, fantastically clear: The Big Bang theory is not a theory of the creation of the universe. Full stop. Done. Call it. Burn that sentence into your brain. Say it before y

Light: Particle or Wave?
Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get too far into it, what is the observer effect?

Scientists have figured out how to shock the salt out of seawater
Researchers have developed a system that uses an electric shockwave to extract salt and other impurities out of salty or contaminated water, and say it could be scaled up for use in desalination or water purification plants, or be used to clean the vast amounts of dirty water produced by fracking. Known as 'shock electrodialysis', the technique applies an electrically driven shockwave to a constant stream of flowing water. The current interacts with the charged salt particles...

Fermilab Experiment Finds No Evidence That We Live in a Hologram
A controversial experiment at Fermilab designed to hunt for signs that our universe may really be a hologram has failed to find the evidence it was seeking, the laboratory has announced. It’s called the Holometer (short for “Holographic Interferometer”), and it’s the brainchild of Fermilab physicist Craig Hogan. He dreamed up the idea in 2009 as a way to test the so-called holographic principle.

Matter will be created from light within a year, claim scientists
Researchers have worked out how to make matter from pure light and are drawing up plans to demonstrate the feat within the next 12 months. The theory underpinning the idea was first described 80 years ago by two physicists who later worked on the first atomic bomb. At the time they considered the conversion of light into matter impossible in a laboratory.

Humans could use mini BLACK HOLE to power world's electricity supply
Stephen Hawking has suggested that humans may be able to harness the power of a ‘mini’ black hole but has warned that it could DESTROY us. The eminent theoretical physicist said if we tried to harness the power of a black hole it could drop into the centre of the Earth - sparking the end of the word. Professor Hawking explained that as particles fall into black holes, they “are constantly materialising in pairs, separating, and then coming together again, and annihilating each other.”

Binary Mixtures of Particles with Different Diffusivities Demix
The influence of size differences, shape, mass, and persistent motion on phase separation in binary mixtures has been intensively studied. Here we focus on the exclusive role of diffusivity differences in binary mixtures of equal-sized particles. We find an effective attraction between the less diffusive particles, which are essentially caged in the surrounding species with the higher diffusion constant.

Humanity could make black holes into power stations, says Stephen Hawking
Small black holes could be turned into power stations, according to Stephen Hawking. The universe could have mountain-sized black holes that could provide enough power to run the entire world’s electricity supply, Professor Hawking has claimed. A huge black hole might be impossible to detect — and despite the fact that they almost certainly exist, the fact that humanity hasn’t been able to observe one has been credited with keeping Professor...
