This week’s lecture had a very similar theme to the previous weeks lecture about the Big Bang Theory. Similar to last week, Professor David Berovici talked about the origin of the Earth and how it was found. He provided evidence of the Big Bang Theory that very much resembled the evidence we mentioned last week. Specifically, the concept that galaxies and other spatial phenomenon’s move away from each other and Olber’s effect, underscore the contradicting arguments of an infinite, old universe. The existence of dark night skies makes us believe the Universe is not necessarily infinite or as old as we think it is. Therefore we begin to question different theories that have been suggested in the past regarding the way the Universe was created.

I very much enjoyed the path that this lecture took in regards to the one from last week. That is, we spoke more about the miniscule fraction of matter we actually make up in the entirety of the Universe. Professor Berovici spoke of the vast amounts of dark energy that account for the majority of the Universe’ matter composition. Once again, the proportionality of our existence in relation to the never ending Universe is astronomical. Putting time into proportion made me reflect on how we as a society are capable of reverting the focus on us, disregarding the fact that we are actually a blip amidst a massive world of matter. This may be because of the interesting, unique characteristics of planet Earth. It’s gravity distinguishes it from other planets. Even the uniqueness of our moon and it’s power to create waves and regulate the speed of Earth’s rotation makes this planet that much more interesting regardless of its’ meaningless proportion to other galaxies. Retrospectively, this process of making the study of Earth and our planet much more extensive could parallel the phenomenon humans our familiar with from the beginning of time- survival of the fittest. In a way, it is a selfish concept in which we prioritize those things that are most relevant to us and look to better our environment and surroundings in order to be adequately equipped to survive to the conditions of the environment. When I mention the fact that this is in a way selfish, I do not mean it negatively. For example, what Professor Berovici focused on was his line of interest in the tectonic plates found on Earth. He drew the importance of knowing their nature and actions to the current events and necessity of having knowledge over the subject. With the recent natural disasters and climatic changes impacting our atmosphere it is very important to be concise and, in a way, selfish with making the study of Earth’s changes a priority. What I most enjoyed about this lecture was the way it made me think about our “little” relevance amongst a gigantic galaxy but also made me realize that in part, it may be due to our human nature to focus and relate the outside world and its’ impact on us.
