Light trespass occurs when unwanted light enters one’s property, for instance, by shining over a neighbor’s fence. A common light trespass problem occurs when a strong light enters the window of one’s home from the outside, causing problems such as sleep deprivation. A number of cities in the U.S. have developed standards for outdoor lighting to protect the rights of their citizens against light trespass. To assist them, the International Dark-Sky Association has developed a set of model lighting ordinances.[12] Some astronomers do not accept inflationary models and have proposed other possible solutions to the horizon problem. These include: scenarios in which the gravitational constant varies with time,5 the ‘ekpyrotic model’ which involves a cyclic universe,6 scenarios in which light takes ‘shortcuts’ through extra (hypothetical) dimensions,7 ‘null-singularity’ models,8 and models in which the speed of light was much greater in the past.9,10 (Creationists have also pointed out that a changing speed of light may solve light-travel–time difficulties for biblical creation.11) Even dim light can interfere with a person’s circadian rhythm and melatonin secretion. A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect, notes Stephen Lockley, a Harvard sleep researcher. Light at night is part of the reason so many people don’t get enough sleep, says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems. Light pollution is a broad term that refers to multiple problems, all of which are caused by inefficient, unappealing, or (arguably) unnecessary use of artificial light. Specific categories of light pollution include light trespass, over-illumination, glare, light clutter, and skyglow. A single offending light source often falls into more than one of these categories. Human health:According to an article published in the journal Environmental Health Perspectives, several studies over the past two decades have suggested that the modern practice of keeping our bodies exposed to artificial light at night increases cancer risk, especially for cancers that require hormones to grow, such as breast and prostate cancers. A second important point is that by concentrating upon the very distant objects, the light travel time problem is not formulated properly, for the situation is far worse! Most treatments of the light travel time problem concentrate upon the question of how we can see objects more than 6,000 lt-yr away. Because most objects clearly visible to the naked eye are well within 6,000 lt-yr, they aren’t a problem in a recent creation. But while it is possible for us to see most of the naked eye stars and today, some millennia after the Creation Week, it would not have been possible for Adam to have seen any stars (other than the sun) for at least four years after his creation. The stars were made on Day Four, and Adam was made on Day Six. The nearest star after the sun is 4.3 lt-yr away, so Adam could not have seen even the closest star for more than four years, and then stars would have slowly winked in over the succeeding years. However, the stars could not have fulfilled their God ordained functions when Adam first saw them after Day Six. These functions include being used to mark seasons and the passage of time (we still do this today with the day, month, and year). The passage of the year and the seasons are reckoned by how the sun appears to move against the background stars as the earth orbits the sun. Absent these background stars, it would not be possible to determine the passage of the year and of the seasons. Therefore, to truly solve the light travel time problem, light from stars even a few light years away must have been visible only days after their creation (and it is likely that the light of all the astronomical objects reaching the earth today also reached the earth at this early time). Any realistic solution to the light travel time problem must explain how Adam could have seen any stars on the evening following Day Six. Once that issue is resolved, the light travel time problem for truly distant objects probably is solved as well. At any rate, we ought to properly formulate the light travel time problem in all discussions of this issue. Reducing light pollution implies many things, such as reducing sky glow, reducing glare, reducing light trespass, and reducing clutter. The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Possible solutions include: Sea turtle hatchlings emerging from nests on beaches are another casualty of light pollution. It is a common misconception that hatchling sea turtles are attracted to the moon. Rather, they find the ocean by moving away from the dark silhouette of dunes and their vegetation, a behavior with which artificial lights interfere.[67] The breeding activity and reproductive phenology of toads, however, are cued by moonlight.[68] Juvenile seabirds may also be disoriented by lights as they leave their nests and fly out to sea.[69][70][71] Amphibians and reptiles are also affected by light pollution. Introduced light sources during normally dark periods can disrupt levels of melatonin production. Melatonin is a hormone that regulates photoperiodic physiology and behaviour. Some species of frogs and salamanders utilize a light-dependent “compass” to orient their migratory behaviour to breeding sites. Introduced light can also cause developmental irregularities, such as retinal damage, reduced sperm production, and genetic mutation.[53][72][73][58][74][75] Many warning lights indicate that a fault has occurred inside the vehicle’s system, but it doesn’t pinpoint the item or system that has failed. In these cases, a code reader or scan tool can help determine the part that needs to be replaced. If an indicator light on your dash is on, visit your local AutoZone store to get the best products and information to help keep your vehicle running in top condition. Determine the frequency of … (GIVEN: 1 m = 109 nm) a. … red visible light (λ = 650 nm) b. … violet visible light (λ = 420 nm) When you report a faulty street light we will inspect it as soon as possible. We normally repair them within 5 working days but where lights are not working because of supply cable faults this could take longer. Steve Mazor, the Auto Club of Southern California’s chief automotive engineer, says that while some people freak out when they see the Check Engine light, “others just put a piece of black tape over it and keep driving.” Mazor says it’s important to promptly address problems indicated by the light. Ignoring them could lead to larger, more costly problems later. Jason Lisle’s 2010 paper published in the Answers Research Journal (meaning, despite his apparent confidence in its explanatory power and his doctoral education in astrophysics, that he was unwilling to submit to peer review – any ideas as to why?) aims to solve the starlight problem by taking advantage of a quirk of physics–it isn’t certain, after 70 years of discussion, whether a “one way” speed of light can be measured or is a convention. Lisle thus proposes that light traveling towards the Earth does so at an infinite speed while light traveling the other way goes at half the measured speed; which is not original to him. Thus it becomes possible for light to arrive from distant stars in line with the 6000-year chronology of young Earth creationism (and equally well, or perhaps even better, with Bertrand Russell’s deliberately ridiculous five minutes ago hypothesis) even though we still measure the speed of light as a fairly lumbering 299,792,458 m/s. Dont stress I tried that method, it didnt work I dropped my camera too I tried to take the picture but the red light wouldnt go away ,all I had to do was keep it off overnight when you wakeup it will be good as new it just needed time to reboot NO BATTERIES NEEDED !TRY THIS METHOD !!!!!
