The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

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 ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light ...

Moving any object at or near the speed of light is currently impossible. "As you get closer to the speed of light, the energy you need grows by a lot," Hornof said. We cannot generate enough energy to ...
