Bioluminescence is the production and emission of light by a living organism. It is a type of chemiluminescence, resulting from specialized enzymes and cofactors emitting light. In this alternate universe, bioluminescence occurs more widely and often presents unique properties compared to the primary universe.
In the primary universe, bioluminescent organisms are predominantly found in marine environments, with few terrestrial species exhibiting this trait. However, in this universe, bioluminescence is more widespread among non-marine organisms. Terrestrial plants and insects commonly display bioluminescence, with many species using it for communication, defense, and attraction. A significant number of arachnids, reptiles, and mammals also exhibit bioluminescence to varying degrees.
Bioluminescence in this universe often appears more intense and vibrant than in the primary universe. Many terrestrial creatures can emit a variety of colors, with certain species capable of displaying a diverse spectrum. These striking colors have led to the creation of bioluminescent gardens and parks, where plants and insects with unique and vivid displays are cultivated. Visitors to such areas are treated to a visually stunning symphony of colors when the organisms are activated.
Bioluminescent bacteria play a more significant role in industrial applications in this universe. These bacteria are employed in structural engineering to detect defects and weaknesses in buildings and infrastructure. By applying bioluminescent bacteria to the surface of a structure, areas with thinning or cracks will become more visible due to light emission. Bioluminescent bacteria are also used in food safety to identify the presence of pathogens, as certain bacteria will glow when exposed to specific contaminants.
In response to energy conservation and light pollution concerns, humans in this universe have sought to employ bioluminescent organisms as a source of night illumination. By harnessing the light-emitting properties of various species, cities have reduced their dependency on artificial lighting. Luminescent plants and insects are strategically placed in urban areas, offering a soft and environmentally friendly alternative to conventional light sources. This approach has resulted in a decrease in overall light pollution, allowing for the clearer observation of celestial bodies and a healthier nocturnal ecosystem.
