What is String Theory?
You may have heard of string theory because it tends to capture the imagination of science reporters. Physicists who have developed string theory are looking for a pattern in the cosmos that goes deeper than the subatomic particles that we know and can study. Since matter and energy can be connected to one another by relativity theory (of Einstein), theorists propose that at a primary level, all matter and energy consists of vibrations of loops of material or energy.
Ideate that everything in the universe of discourse was part of a constantly moving and changing pictorial tapis, and that strings make up everything in the universe. Yet, these strings do not vibrate in three dimensions like a fiddle string. They vibrate in as many as eleven dimensions. All of the strings are the same. It is the vibrations that differ among the various types of particles. In other words, while we may be able to see atoms and molecules and electrons and photons and other subatomic atoms, we cannot see the strings themselves.
String theory is a strictly mathematical thought. We cannot see the strings and no test has ever been developed to determine whether they exist. Using the equations of string theory, scientists have attempted to predict energy interactions, even the gravitational actions predicted by Einstein, and weave everything into a unified approach to quantum mechanics.
