In high school I was given the chance to take a semester-long cosmology course. I am not talking about the study of beauty treatment (Cosmetology), as many girls in the class realized the hard way, but the study of the origins of the universe and the evolution it undergoes (Cosmology). The class was taught by one of the most interesting people I have ever met. He was a 28 year old physics teacher who previously taught undergrads and carried out research for NASA. Needless to say, he was very knowledgeable in the subject. We discussed many topics such as star formation, the big bang theory, black holes, relativity concepts, time, the inflation theory, extra-terrestrial life, and other mysteries of what we call “space”.
The class really put into perspective for me the importance of the earth to US. In an infinite universe, the earth hardly seems important or significant at all; it, along with many other planets, is just a drop in the ocean. But planets that can harbor complex life as perfectly as earth can are few and VERY far between. We do not have the technology to locate and migrate to planets that have conditions suitable for life. “There is no PLANet B” as many of the banners at the People’s Climate March on September 21st pointed out.
Actions against climate change need to be made now. Humans need to start developing and executing sustainable solutions, so that generations to come can share in the greatness of mother earth. We can all contribute in some small way, whether it be composting and recycling in the school cafeteria, reusing water bottles, or using less gasoline by taking public transportation.
I would recommend that people explore the topic of cosmology. It can really open your eyes to the things that often go unnoticed, but are the most important.
