What's up in
The pot-stirring string theorist and quantum gravity theorist never sits still for long.
One of the world’s preeminent theoretical physicists seeks a quiet place to think.
Recent calculations tie together two conjectures about gravity, potentially revealing new truths about its elusive quantum nature.
The search for exotic new physical phenomena is being led by huge experiments like the Large Hadron Collider. But at the other end of the spectrum lie tabletop experiments — small-scale probes of hidden dimensions, dark matter and dark energy.
