Why is it that sound travels faster at night than during the day time? | [
"Its not that sound travels *faster* at night, it's that it can be heard along the same plane from a further distance.

Why is dog racing so frowned upon but horse racing is praised worldwide? | [
"It's because the dogs are far more exploited than the horses and they are given a lowered quality of life. Racing horses, like any horse may, will live in stables. But those are the most valuable horses alive and they are taken very good care of. When they are ready to retire they are put out to stud. The dogs... | [

How do color blind people deal with the fact that traffic lights are red and green? | [
"Because traffic lights [aren't one color](_URL_0_), the red light has some yellow light mixed in, and the green light has some blue light. So the orientation isn't an issue in most cases. My biggest issue is confusing streetlights for green lights at night in cities that put their stop lights on the side of the r... | [
"Green and Orange (yellow actually) are used on stop lights and emergency signs. When somethings going to come barreling down the street extremely fast and unable to stop easily, you want there to be absolutely no confusion. Since so few things use blue lights, it works out well."

Why do gaming companies not re-make old consoles and re-release old games? | [

What mechanism do self-dimming mirrors use to dim? | [

"A lot of modern cars use LEDs, now LEDs don't really dim, they actually just flash on and off really fast to give the perception of them being dimmer. So, if the same bulb is used for the high beams, then the regular headlight brightness will be achieved by dimming."
