Science News is honoring the 100^th anniversary of Einstein鈥檚 general theory of relativity this November with a special issue centered on that theme. , published in the October 17 issue of Science News, as well as select stories from our archives are available free of charge on our website. It includes:

• 鈥� 鈥� Einstein鈥檚 genius reconstructed science鈥檚 perception of the cosmos.鈥� This essay includes an interactive timeline and explainers of some of the core ideas in general relativity.
• 鈥� 鈥� Using general relativity to see deep into space.鈥�
• 鈥� 鈥� Wormhole links between black holes could broker quantum鈥揼eneral relativity merger.鈥� This feature includes a video explainer of quantum entanglement.
• associated with general relativity

In 鈥淕etting a grip on gravity,鈥� Managing editor Tom Siegfried describes the challenges that Einstein faced in developing the general theory of relativity, which reimagined gravity as a warping of spacetime. Einstein struggled for years to solve the puzzle, and the pieces all fell into place in November 1915.

Chris Crockett, astronomy writer at Science News, focuses in his feature on gravitational lensing and how we can see farther and deeper into space. 鈥淕eneral relativity isn鈥檛 some stodgy theory; it鈥檚 a launching pad to look deeper into the universe than ever before,鈥� Crockett says. The feature focuses on technology we are using now, and how that is aiding our search for ripples in the fabric of space and time.

Andrew Grant, physics writer at Science News, describes his feature as a wild mix of topics including wormholes and holograms that are usually reserved for science fiction. Yet scientists are taking them seriously to resolve deep mysteries about the universe. Unlike many Einstein stories that focus on whether the brilliant physicist was right or wrong, Grant鈥檚 story reveals how cutting-edge researchers are building on Einstein鈥檚 incredibly successful theory.
