Albert Einstein’s general theory of relativity is a landmark in our understanding of the universe. This arises the idea of a spacetime continuum against all physical phenomena in play. But over the decades, it has inspired many unanswered questions: How can Einstein’s equations describe forces other than gravity? And what are the “dark” forms of energy and matter that cause the expansion of the universe and the development of galaxies?
In a new article, author Piotr Ogonowski offers a simple solution — the theories of spacetime and electromagnetism describe the same things. Starting with Einstein’s field equations, Ogonowski revealed their ability to describe all known physical interactions, including those described in classical electromagnetism. Spacetime, it appears, may be the only way to detect electromagnetic fields.
To support the consistency between spacetime and electromagnetism, the author describes how the cosmological constant in Einstein’s theory, which is believed to be responsible for dark energy is actually a description of an electromagnetic field. The conclusions drawn may be far-reaching. If further research confirms these findings, it means that Einstein was right from the beginning and that General Relativity explains more than gravity.
