Albert Einstein

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."

Discoveries that back up Einstein’s theory of general relativity are still being made. The latest comes from the Max Planck Institute, where astronomers have watched how the supermassive black hole at the center of the Milky Way pulls and stretches the light from a star as it makes its closest pass.

The theory of relativity predicts that any two objects in a vacuum will fall at the same rate. Whether or not this applied to massive objects like planets and stars has long been debated, but now astronomers have shown that the phenomenon does hold true, meaning Einstein was right yet again.

A violin crafted for, and belonging to, Albert Einstein has achieved $516,500 at a Bonhams auction in New York. The first Einstein violin to ever be offered at auction set a new record for Einstein memorabilia.

The final round of scientific auctions for 2017 occurred last week and there were the usual puzzling results in a market slightly off the boil. There were some rare scientific documents and instruments to be had at reasonable prices that will return a handsome profit in the short to medium term.
