Air Quality is a big concern now a days for many reasons. Many people need to worry about their local air quality because of health compilations such as asthma. Environmentalists worry about air quality because it can affect the ecosystem within that region. So i compared the air quality of our county (Wayne) and the 2 counties above and below us (Macomb, Monroe). After comparing the counties, Wayne had the worst air quality of the three. This makes sense if you know the demographics of the area because Wayne county is very industrialized due to the auto industry and other manufacturing industries that downgrade air quality. Monroe and Macomb both were tied for the best air quality between these counties.
Now counties are just small sections of states so I compared the air quality of three states. I chose these states because of their locations, it had nothing to do with industry or population. I compared the air quality of Michigan, Florida and California. Of these three California had the worst air quality and Florida had the best. Michigan's air quality was very close to Florida's though.
I compared Wayne County with monthly averages and I found out that the worst time for someone to visit was in February and the best time to visit is from March to June. This information would be very important to anyone with health problems visiting the area.

Black Holes
A black hole is an object so compacted together that its gravity is so strong it prevents any light or objects from escaping. There are three types of blacks holes that scientists believe exist. There is the stellar mass, super massive and there is a third one that is thought to be in between. Out of these three i think the super massive is my favorite because its so large that its as heavy as a small galaxy. That's amazing to think of what it could pull in with its gravitational forces.
Black holes can spin around an axis, astronomers believe some spin but are not entirely sure. They form from when an object cant withstand its own gravity. Stellar mass holes form with a bang when a star nearly 25 times larger than the sun runs out of nuclear fuel.
Some misconceptions about black holes is that they are like a vacuum and suck up anything around them. Black holes have enormous gravitational pull but objects only enter them when there orbit crosses into the black hole. Wormholes is another misconception, although not proven wrong most astronomers disregard the idea. Wormholes are the idea that there is another exit to the black hole that takes to another part of the universe.
