Physicists discover light property that enables spinning patterns in empty space

An international team of physicists, led by researchers at the University of East Anglia in the United Kingdom and working with scientists in South Africa, has discovered that light can develop spinning patterns as it moves through empty space. This phenomenon occurs without the need for specialized lenses, mirrors, or specific materials.

The discovery reveals a hidden geometric structure within light that allows it to be controlled through its own internal geometry. This finding challenges previous assumptions regarding how the properties of light interact and how its spin and twist can be manipulated.

One key aspect of the research involves chirality, the property of being left-handed or right-handed. Because many molecules, including those used in medicine, exhibit chirality, being able to control light's rotational behavior could lead to more sensitive medical testing. Additionally, the discovery may advance quantum technologies, secure communications, and high-speed data transmission.
