Will Einstein's General Relativity Break Under Extreme Conditions?
A century ago this year, a young Swiss physicist, who had already revolutionized physics with discoveries about the relationship between space and time, developed a radical new understanding of gravity. But until recently, it wasn't possible to do experiments to probe the theory under extreme conditions to see whether it breaks down.

Detection of mini black holes at the LHC could indicate parallel universes in extra dimensions
A group of physicists has suggested that the Large Hadron Collider (LHC), the largest particle collider in the world, may be able to uncover the existence of parallel universes.

Large Hadron Collider to search for parallel universes
The particle-smashing Large Hadron Collider (LHC) in Cern, Switzerland, will restart next week and one of its major projects will be to search for tiny black holes, which could be gateways to parallel universes and new dimensions.

The Bridge From Nowhere - Nothingness
The question of being is the darkest in all philosophy.” So concluded William James in thinking about that most basic of riddles: how did something come from nothing? The question infuriates, James realized, because it demands an explanation while denying the very possibility of explanation. “From nothing to being there is no logical bridge,” he wrote. In science, explanations are built of cause and effect. But if nothing is truly nothing, it lacks the power to cause.

Scientists create dark matter 'map' to see invisible space
We've finally gotten our first glimpse at the mysterious material that supposedly makes up 27 percent of the universe. It's only taken two years of research, the efforts of 300 researchers working for the Dark Energy Survey (DES) and a 570-megapixel camera attached to the Victor Blanco telescope in Chile to do so.

Cold cosmic mystery solved: Largest known structure in the universe leaves its imprint on CMB radiation
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in ...

Is the universe a hologram?
The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional -- just like a hologram.

Is Our Universe a One-Off Fluke, or an Endless Cycle?
Paul Steinhardt is torn. On the one hand, he has been working on and contributing to the theory of inflation for decades. On the other hand, he thinks it may very well be wrong. Inflation describes the early universe going through an unimaginably rapid expansion in its infancy, from the size of an atomic nucleus to something like the size of the current observable universe, in an infinitesimal fraction of a second.

The Fermi Paradox — Where Are All The Aliens?
The universe is unbelievably big – trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?

Is the Universe a Giant Computer Simulation? Here's the Evidence
Our universe seems real, but is it really? As humans get better at simulating artificial intelligence, it seems at least plausible that we could create life that is both conscious and has free will. And if we can create conscious life, who's to say that the universe, as we know it, wasn't created by superintelligent artificial intelligence who wanted to simulate their past?
