Abstract
The famous quote of Antoine Laurent de Lavoisier (18th century) "Nothing is lost, nothing is created: everything is transformed" illustrates a principle that has marked minds throughout modern history. It deals with the principle of energy conservation. In our minds, energy is conserved in our world (in our dimensions). If part of the energy drifts out of our dimensions, this will contradict the statement "Nothing is lost." If some energy penetrates our dimensions, this will contradict the statement "Nothing is created." Everything is transformed within our dimensions. This article discusses the latest attempts through cosmic theories, still unverified, that have tried to explain the start and development of the universe even at the cost of concepts and principles unanimously agreed to date by the scientific community through the history, such as the principle of conservation of energy. This article raises some questions that we scientists must answer before we move forward. We must from time to time take a step back and have a critical look at our scientific progress before we branch off into a web of various theories. (C) 2020 Physics Essays Publication.
