Dark Matter

Dark matter is believed to made up of non-baryon material. Dark matter consists of particles that do not absorb, reflect or emit light. Dark matter is a material that cannot be seen directly. Dark matter exists and scientists know it exist because of the effect it has on objects that we can observe directly. Understanding dark matter is important in the process of understanding the size, shape and future of the universe. The amount of dark matter in the universe will determine if the universe is open, closed, or flat. As a galaxy spins it should be torn apart but gravity is what holds it together. Scientists believe that dark matter is what may be helping gravity hold the galaxy together and not spin out of space.

    its weird how something that we can barely see can cause so much damage. It is also weird that it can cause the fate of our future. Pretty scary.

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
