Light pollution is the adding-of/added light itself, in analogy to added sound, carbon dioxide, etc. Adverse consequences are multiple; some of them may not be known yet. Scientific definitions thus include the following: Kyba et al. (2014 Kyba, C., Hänel, A., & Hölker, F. (2014). Redefining efficiency for outdoor lighting. Energy & Environmental Science, 7, 1806–1809.10.1039/C4EE00566J[Crossref], [Web of Science ®] [Google Scholar]) mention the tricky issue of ‘shifting baseline syndrome’. As nights get brighter, people have a new conception of what ‘normal’ levels of light are, and base their evaluations of acceptable levels of brightness on this. A focus on needs could help to overcome shifting baselines. But, such an approach risks omitting the preferences of local stakeholders, and as such may create technocratic and paternalistic policies. This may contribute to downstream value-level conflicts when regulations are enacted. For example, safety is a central facet of nighttime lighting and an important value intertwined with urban nightscapes. While the correlation between increased lighting and increased safety is contentious, research suggests that lighting influences feelings and perceptions of safety (King, 2010 King, C. (2010). Field surveys of the effect of lamp spectrum on the perception of safety and comfort and night. Lighting Research & Technology, 42, 313–329.[Crossref], [Web of Science ®] [Google Scholar]), and that feelings of fear increase at night (Li et al., 2015 Li, Y., Ma, W., Kang, Q., Qiao, L., Tang, D., Qiu, J., … Li, H. (2015). Night or darkness, which intensifies the feeling of fear? International Journal of Psychophysiology, 97, 46–57.10.1016/j.ijpsycho.2015.04.021[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Such findings represent a challenge for needs-based nighttime lighting efforts. Attention to the preferences of local stakeholders becomes critical to the creation of regulations that will be supported and successful. The frame creation model discussed above (Dorst, 2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar]) is but one approach that incorporates the values and desires of stakeholders; a variety of other participatory or value-focused design strategies could also be effectively utilized to address conflicts of this nature.

The light travel time problem is one of the greatest challenges that recent creationists face today. Simply defined, if the universe is only thousands of years old as the Bible strongly suggests, then how can we see objects that are at light travel time distances far greater than a few thousand years? A popular unit of distance used in astronomy is the light year, the distance that light travels in a year. Multiplying the speed of light by the number of seconds in a year, we find that the light year is a little more than 9 × 1012 km. Obviously, using “normal” units of distance measurements such as meters or kilometers is woefully inadequate in astronomy, hence the definition of this new unit of distance. With the most straightforward approach to the biblical record and the vast distances in astronomy, we ought not to see any objects more than a few thousand light years away. Most of the objects visible to the naked eye are not this far away, so, as the light travel time problem normally is defined, most objects visible to the naked eye do not present a problem to the recent creation model. Disputes are still common when deciding appropriate action; and differences in opinion over what light is considered reasonable, and who should be responsible, mean that negotiation must sometimes take place between parties. Where objective measurement is desired, light levels can be quantified by field measurement or mathematical modeling, with results typically displayed as an isophote map or light contour map. Authorities have also taken a variety of measures for dealing with light pollution, depending on the interests, beliefs and understandings of the society involved.[citation needed] Measures range from doing nothing at all, to implementing strict laws and regulations about how lights may be installed and used. It is worthwhile to quickly note that, as with most transformational technologies, nighttime lighting has not always been met with open arms. Hasenöhrl (2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar], p. 105) notes that while the introduction of new lighting technologies was in general positively received, this did not imply universal endorsement or ‘a universal devaluation of the “dark night” as a whole’. The consequences of artificial nighttime lighting have been under debate since the nineteenth century, and some criticisms of artificial nighttime lighting can be found even earlier.55. Criticisms can be found as early as 1662, when a London pastor stated ‘We ought not to turn day into night, nor night into day … without some very special and urgent occasion’ (Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar], p. 74). This was due to the disruption of the perceived natural (Christian) order that such lighting may cause. However, most criticisms are found in the nineteenth century onward, and specifically around times of transition between technologies. Early objections were often esthetic, however moral objections can also be found (Hasenöhrl, 2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar]). There are documented criticisms of artificial nighttime lighting in astronomy-related literature as early as 1866 (Sperling, 1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar]). Already in the 1880s, Alexander Pelham Tottler—generally regarded as the originator of the scientific study of lighting—identified issues with street lighting that predict modern debates. For example, he argued that too much light is wasted, and that glare causes safety concerns (Bowers, 1998 Bowers, B. (1998). Lengthening the day: A history of lighting technology. Oxford: Oxford University Press. [Google Scholar]). Naturalists and artists expressed ambiguity (at best) towards artificial light as early as the 1920s (Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar]), and by this time there were already some calls for lighting engineers to reduce urban brightness (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from https://placesjournal.org/article/good-night/[Crossref] [Google Scholar]).View all notes The most outspoken critics have been astronomers, as reduced stellar visibility has been a long-noticed effect of urban lighting (Sperling, 1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar]). Still, in the larger narrative of lighting technologies these objections were the exception—nighttime lighting was mostly seen as necessary and desirable for modern urban life (Hasenöhrl, 2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124).
