👉 Infectious-light particles, often referred to as photons or other forms of electromagnetic radiation, are fundamental components of light but can be conceptualized as energy packets that travel through space. Unlike biological pathogens, these particles do not require a host to survive or replicate; instead, they propagate through the electromagnetic spectrum by transferring energy from one point to another. Photons, the most common form of infectious-light particles, are massless and travel at the speed of light, making them ubiquitous in the universe. They can interact with matter through processes like absorption, reflection, and scattering, but unlike viruses or bacteria, they do not replicate within a host. This characteristic makes them inherently non-infectious in the biological sense, though they can cause effects such as photochemical reactions or damage to biological tissues when absorbed in excessive amounts.
