Physicists using ultrafast electron microscopy observed empty voids (singularities) in phonon-polariton waves inside a thin boron nitride sample that move faster than light. Because these voids contain no information, their superluminal motion does not violate special relativity, and the work reveals universal laws of wave dynamics with potential to advance ultrafast studies across physics and materials science.
Brian Haidet's experiment captures laser beams at 2 billion frames per second, revealing how light appears to travel faster towards the camera due to an artifact related to special relativity, achieved through a highly upgraded setup.
Physicists in Vienna used ultra-fast lasers and cameras to simulate the Terrell-Penrose optical illusion, demonstrating how objects moving at near-light speeds appear rotated due to light's travel time, confirming a century-old prediction of special relativity in a lab setting.
An interstellar project called Breakthrough Starshot Initiative aims to use light-powered space travel to drastically reduce the time it takes to travel across space, potentially enabling speeds of up to 100 million miles per hour. By utilizing solar sail technology and lasers, the project could make it possible to travel from our solar system to the neighboring one in just 20-30 years, a journey that currently takes 76,000 years with existing technology. The initiative hopes to inspire the next generation of young minds to make futuristic space travel a reality.
