Physicists prove 65-year-old effect of relativity by making an object appear to move at the speed of light

Physicists prove 65-year-old effect of relativity by making an object appear to move at the speed of light

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein’s theory of special relativity. One consequence of special relativity is that fast-moving objects should appear shortened in the direction of motion — a phenomenon known as Lorentz contraction. This effect has been confirmed indirectly in particle accelerator experiments. But in 1959, mathematician …

Einstein’s relativity could rewrite a major rule about what types of planets are habitable

Einstein’s relativity could rewrite a major rule about what types of planets are habitable

The planets around white dwarf stars might provide long-term homes for alien life, but they suffer from a fatal overheating problem. Who’s going to rescue them? According to new research, it’s none other than Albert Einstein. White dwarfs are the compact remnants of dead sun-like stars. They litter the universe, with the Milky Way alone home to hundreds of millions …
