We can see the emergence of the concept of light pollution as—at least in part—a reactionary shift in perception to the widespread proliferation of electric illumination at night. A recent New York Times article quoted a behavioral ecologist as stating that we need to ‘start thinking of a photon as a potential pollutant’ (St. Fleur, 2016 St. Fleur, N. (2016, April 7). Illuminating the effects of light pollution. New York Times. Retrieved 7 April, 2016, from [Google Scholar]). To accept this re-framing is to begin seeing artificial nighttime lighting as spreading polluting photons into the atmosphere, the environment, and ourselves. Answers will likely take the form of either preservation or mitigation strategies—certainly not a bad approach, but it does draw attention to the importance of light pollution as a framework through which solutions can emerge. Regulations and strategies based on light pollution will necessarily focus on reducing the negative or adverse effects of nighttime lighting; on protecting those things or resources affected, and/or cutting out that 30% of lighting considered to be ‘wasted’ (Gallaway et al., 2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar]). As a regulatory tool, this can be quite useful, and follows a similar strategy as attempts to regulate other pollutants. Ten percent of all cars on the road have a Check Engine light on, and the drivers of half of these cars have ignored the light for more than three months, says Kristin Brocoff, a spokesperson for The company sells a $119 device that reads engine codes and provides access to a Web site database that identifies the problem (according to the code) and estimates the cost of repair. We’re converting many of our street lights to energy-efficient Light Emitting Diode (LED) technology. Read more about our LED street lighting project. 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. Hey. My camera also fell like a week ago and the red light near the lense won’t go and if I take a photo, the film won’t come out like if I didn’t had any. Hey.

The problem with the last bulb is this; the dimmer switch itself needs to see a suitable load. i.e. it is happy working into a standard filament bulb. It’s driving all your lights in parallel, so whilst there is one regular bulb in there the dimmer is still happy. At the point you replace that last bulb with an LED lamp, the dimmer now sees only LED electronics as its load. The dimmer will not function properly (due to the way it works, it won’t fire correct) and the result is it sends occasional pulses to the lights in its confusion and you observe the flickering. According to Mario Motta, president of the Massachusetts Medical Society, “… glare from bad lighting is a public-health hazard—especially the older you become. Glare light scattering in the eye causes loss of contrast and leads to unsafe driving conditions, much like the glare on a dirty windshield from low-angle sunlight or the high beams from an oncoming car.”[25] In essence bright and/or badly shielded lights around roads can partially blind drivers or pedestrians and contribute to accidents. Experts say that many drivers confuse the “service required” light on the gauge cluster for the Check Engine light. These warning lights are unrelated. The service required light just means the car is due for an oil change or other routine maintenance. It is not the indicator of trouble that the Check Engine light is. When artificial light affects organisms and ecosystems it is called ecological light pollution. While light at night can be beneficial, neutral, or damaging for individual species, its presence invariably disturbs ecosystems. For example, some species of spiders avoid lit areas, while other species are happy to build their spider web directly on a lamp post. Since lamp posts attract many flying insects, the spiders that don’t mind light, gain an advantage over the spiders that avoid it. This is a simple example of the way in which species frequencies and food webs can be disturbed by the introduction of light at night. Some lights are flickering or blinking. This represents a Poor connection somewhere along the circuit. If the blink happens through much of the home, a Main wire connection could be the one having the trouble. The big bang model assumes that the universe is many billions of years old. While this timescale is sufficient for light to travel from distant galaxies to earth, it does not provide enough time for light to travel from one side of the visible universe to the other. At the time the light was emitted, supposedly 300,000 years after the big bang, space already had a uniform temperature over a range at least ten times larger than the distance that light could have travelled (called the ‘horizon’)11 So, how can these regions look the same, i.e. have the same temperature? How can one side of the visible universe ‘know’ about the other side if there has not been enough time for the information to be exchanged? This is called the ‘horizon problem’.12 Secular astronomers have proposed many possible solutions to it, but no satisfactory one has emerged to date (see Attempts to overcome the big bang’s ‘light-travel–time problem’). Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories,[5] and, like any other form of pollution, disrupts ecosystems and has adverse health effects[6][7] A full cutoff fixture, when correctly installed, reduces the chance for light to escape above the plane of the horizontal. Light released above the horizontal may sometimes be lighting an intended target, but often serves no purpose. When it enters into the atmosphere, light contributes to sky glow. Some governments and organizations are now considering, or have already implemented, full cutoff fixtures in street lamps and stadium lighting. The anthropic principle is based on the observation that any small change in any of the basic constants of physics, which include the speed of light, would make human life impossible. In the 1600s, Ole Roemer became one of the first scientists to make a measurement of the speed of light. Roemer observed the orbits of Jupiter’s nearest moon and recognized that its orbital period was observed to be approximately 22 minutes longer when measured from Earth when it was furthest from Jupiter compared to when it was closest to Jupiter. Roemer reasoned that the difference was due to the fact that it took longer for light from Jupiter to travel the extra distance when Earth’s position was on the opposite side of the Sun from Jupiter. The distance d2 is 2.98×1011 m greater than the distance d1. Determine Roemer’s estimate of the speed of light in the 1600s.
