Albert Einstein

Wormholes are a sci-fi staple, and and it's possible that they exist in the real universe. But how would they work? Physicists have now used a quantum processor to simulate a traversable wormhole, teleporting information between two quantum systems.

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest distance yet.

This is the second part of our overview of the 2021 auction year – a year where investors channeled more of their wealth into “investments of passion” than ever before. It covers the 150 science, sci-fi and technology artifacts that sold for more than $100,000

A 54-page document handwritten in 1913-1914 by Albert Einstein and Swiss engineer Michele Besso, sold earlier today for €11.6 million. It’s the most paid in nearly eight decades for an autograph document by history’s most celebrated scientist.

Why is the expansion of the universe accelerating? The leading hypothesis is a repellent force that astrophysicists refer to as “dark energy." But how does it work? What does it mean for our future? And how sure are we that it even exists?

Albert Einstein is the world’s most recognizable and universally loved scientist. So when a handwritten letter appeared at auction in which Einstein wrote his most famous equation in his own hand, it was logical that it should sell for a grand amount.

Faster-than-light “warp drives” may be theoretically possible, but they usually involve exotic physics well out of our reach. Now an astrophysicist has outlined a hypothetical design that could allow FTL travel using conventional physics.

Almost 30 years of observations has revealed that a star in the center of the galaxy orbits the supermassive black hole Sagittarius A* in a rosette, or spirograph shape. The find once again confirms a prediction made by Einstein’s General Relativity.

Even 100 years after the theory of general relativity, new observations keep confirming its predictions. Now, Australian astronomers have found that high-density stars in close orbit appear to be dragging and twisting the fabric of spacetime itself.

Astronomers have studied the ringing tones of a newly-created black hole for the first time, proving Einstein right once again.

The month of July, 2019 will be a bumper one for the number of landmark scientific artifacts heading for auction. Three Christie's auctions and a Sotheby's auction have a stellar array of landmark scientific items, some of them estimated to sell for quite affordable amounts.

Quantum entanglement is an eerie concept that Einstein himself had trouble accepting, and yet it’s been experimentally demonstrated. To find out whether there are other variables, a new experiment provides the strongest evidence so far of quantum entanglement or a 12-billion year “conspiracy."
