Why Einstein must be wrong: In search of the theory of gravity

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities ...

Scientists discover exotic quantum state at room temperature

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This breakthrough, published as the cover article of the October issue of Nature Materials, came when Princeton ...

Why the universe might be a hologram

A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...

Rate of scientific breakthroughs slowing over time: Study

The rate of ground-breaking scientific discoveries and technological innovation is slowing down despite an ever-growing amount of knowledge, according to an analysis released Wednesday of millions of research papers and patents.

Is the end of the 'particle era' of physics upon us?

The discovery of the Higgs Boson in 2012 represented a major turning point for particle physics marking the completion of what is known as the standard model of particle physics. Yet, the standard model can't answer every ...
