The illusion makes clever use of colour theory, demonstrating how our brains perceive colours differently against certain ...

Optical illusions come in all forms, from the cognitive to the physiological, often boggling our brains beyond our ...

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, ...

Optical illusions occur naturally in different habitats and conditions across the world. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt flats ...

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Optics is a branch of physics that involves the properties of light and its interaction with matter. Reflection, refraction and diffraction are different ways light can behave based on the conditions ...

Earth's passage through the plane of Saturn's rings, occurring roughly every 15 years, causes the rings to appear nearly edge-on. The next such event in March 2025 will be poorly observable due to ...

An optical illusion is a visual phenomenon in which our perception of an image differs from objective reality. This image is ...
