What are strings in string theory made of?
Being composed of quarks, all hadrons are of course bound together by the strong force, and therein likes the real, experimentally meaningful Answer to what the questions of what strings are composed of: All real, experimentally meaningful strings are composed of the strong force.
Who created string theory?
The key theorist behind these early models would probably be Gabriele Veneziano. The string theories turned out to be the wrong model for hadron physics, but were later adapted to their present role as a theory of all elementary particles by a number of theorists.
What are the strings of string theory made of?
2. In string theory the strings are fundamental objects and cannot be made of anything. However, the strings of string theory, like more general extended objects –e.g., the membranes in brane theory–, can be considered to be made of more fundamental point-like objects.
Is string theory a consistent theory of gravity?
In coming to understand this calculation, Edward Witten became convinced that string theory was truly a consistent theory of gravity, and he became a high-profile advocate. Following Witten’s lead, between 1984 and 1986, hundreds of physicists started to work in this field, and this is sometimes called the first superstring revolution .
What are some of the challenges of string theory?
One of the challenges of string theory is that the full theory does not have a satisfactory definition in all circumstances. Another issue is that the theory is thought to describe an enormous landscape of possible universes, which has complicated efforts to develop theories of particle physics based on string theory.
Why is string composition so complex?
Its composition — what is is made of — is particularly complex. Real strings are composed out of a statistically unlikely form of long-chain bonding, which in turn depend on the rather unlikely properties that emerge from highly complex multiparticle entities called atoms.
