For my English class, I wrote this essay about where energy first came from. I’ve always wondered about this topic and learned so much about it when I was doing my research.
Where did energy first come from? It’s an almost impossible question to answer since we can’t go back in time. As the Law of Conservation of Energy (or the first law of thermodynamics) states, energy cannot be created or destroyed, but it must have been created sometime to exist in our universe.
Energy is defined as the capacity to do work. It can exist in different forms, like sound energy, chemical energy, potential energy, and more. Energy has to have come from somewhere, so where did it come from. The Big Bang is thought to have created everything, but the Big Bang would have needed energy to happen. This means that it isn’t possible for the Big Bang to have created energy and that energy was created before the Big Bang. The universe is a closed system, meaning that energy levels are always at a constant. The amount of energy in the universe from when it was first created to now has always been the same. E=mc² (or energy= mass x the speed of light squared) says that energy and mass can be converted into each other or that a bit of mass can be converted into a lot of pure energy. Mass is a form of stored energy, which means that if we could figure out where mass first came from, we could figure out where energy originated.
Energy cannot be created or destroyed, but it must have come around somehow. There are many explanations, some of which are possible, yet it is a question which can never be answer.
