Recent research suggests that dark matter could influence the color of light from distant galaxies, either slightly blue-shifting or red-shifting it depending on its properties, which might help us better understand its nature. The study explores how dark matter interactions could subtly affect light, offering a new way to investigate this elusive component of the universe.

Researchers have discovered that under certain conditions, a laser beam can cast a shadow, challenging traditional understandings of light and shadow. By directing a high-power green laser through a ruby crystal and illuminating it with a blue laser, the green laser increased the optical absorption of the blue light, creating a visible shadow. This finding, published in Optica, opens new possibilities for technologies that use laser beams to control other light sources, such as optical switching and precise light transmission control.
