RTINGS Home Theater/YouTube Unfortunately, manufacturers have yet to fully eradicate image retention. Several major display makers, such as LG , Samsung and Sony, host webpages coaching users on how to prevent burn-in. Phone manufacturers that deploy OLED screens, such as Google and Apple, also warn users about the potential for image retention. As LG reminds its users on its website, "it is possible to create image retention in almost any display if one really tries hard enough." It is important to stress that burn-in won't likely occur after just a few hours. Rather, tests indicate that perm

Starlink satellites were designed to burn up when they re-enter our planet's atmosphere. To prevent accidents, however, the company typically deorbits its satellites over open oceans and away from populated islands and locations with heavy air or maritime traffic. After all, one accidental collision could have a huge impact on the satellite broadband industry. To be able to target specific locations for re-entry, SpaceX maintains attitude control down to very low altitudes of around 125 km. However, SpaceX admitted that its satellites do have components that are likely to survive re-entry with

Well, that's what scientists are still trying to figure out. The number of satellites in orbit will only continue to grow, as both American and Chinese companies launch them in big batches for their mega-constellations. In the US, there's Amazon, aside from SpaceX, which is also building a constellation for its Leo broadband service. As Harvard Climate Brief explains, when a satellite's organic materials, like carbon-fiber composites, burn up, they release black carbon particles, or what's simply known as soot. At the moment, their impact on the atmosphere, if any, is still unclear. Scientists
