String theory is a theory that attempts to explain and group the four known fundamental interactions of the universe, which are electromagnetism, strong nuclear force, weak nuclear force and gravitation, into one theory. String theory is a model that attempts to elucidate the phenomena of the universe that are incomprehensible under standard models of quantum physics.Know More
At its foundation, string theory utilizes one-dimensional strings with specific frequencies in place of the standard particles of quantum physics. The formulas stemming from string theory predict a multitude of dimensions, which number 10 or 11 in common string theory models but up to 26 in other versions.
These added dimensions, however, “curl up” within the strings. The average size of these strings is roughly a millionth of a billionth of a billionth of a billionth of centimeter, which is much too small to be seen by current or applied particle physics technology. String theory also refers to another fundamental object known as a “brane.” Branes contain multiple dimensions, and, in some theories, the universe exists within a 3-dimensional brane.
String theory is an evolving science; however, all variations of string theory posit the existence of multiple dimensions and attempt to explain the relationship between gravity and quantum physics. String theory was developed in the 1970s to explain the ambiguities associated with physics and the energy behavior of hadrons.Learn more about Physics
Space-time is a mathematical and physical construct that explains how space and time interact; the three physical dimensions and one time dimension combine to create the four-dimensional nature of the universe. Space-time resulted from Albert Einstein's work on relativity.Full Answer >
Friction always opposes motion between two surfaces, although it is not a fundamental force of the universe like gravity. The coefficient of friction is used to describe the ratio of friction between two bodies and the outside force pressing them together.Full Answer >
Astrophysics is a subdivision of astronomy concerned with the structures and properties of cosmic objects in the universe. Astrophysics deals with the physical nature of terrestrial bodies and stars rather than their movements and positions in space.Full Answer >
Explosions consist of a chemical reaction or a series of reactions in which a substance burns or decomposes very quickly, almost instantaneously, producing intense heat and gases that expand very rapidly. If the gas expansion is faster than the speed of sound in the air, the explosion produces a shock wave. Due to the rapid expansion, explosions apply force to surrounding objects and have the potential to cause damage.Full Answer >
