String theory : Moving closer to a theory of everything
Image credit : treehugger.com Introduction As our knowledge increases we tend to see that what is unknown is also increasing and as we study the four fundamental forces of nature, that is electromagnetic force, gravitational force, strong nuclear force and weak nuclear force, we cannot say that these are the only forces of nature but our known fundamental forces of nature. Let’s get to 1600 where William Gilbert stated that earth is also a giant magnet and that is the reason the magnets point towards the north-south direction(geomagnetic north and south poles). In the 1800s Hans Christian oersted and Michael Faraday found out the relationship between electricity and magnetism, we get that these two forces are the same known as electromagnetic force. And there was the Newton’s law of gravitation but after Einstein found out in the year 1905 (known as his year of miracles) he discovered the Special theory of relativity and then General theory of relativity this unified gravity, space,
