What Is String Theory?Sen, Ashoke
String theory is primarily a theory of quantum gravity which elegantly combines the theories of gravity and quantum mechanics. Physicists have been searching for a theory of quantum gravity for nearly one hundred years. Moreover, ideas from string theory have been used to solve problems in mathemat...
“Fluctuating Geome-tries in Statistical Mechanics and Field Theory.” The first part is an introductionto conformal field theory and string perturbation theory. The second part dealswith the search for a deeper answer to the question posed in the title.1Electronic address: joep@sbitp.itp.ucsb....
NASA's Chandra X-ray Observatory helped power an experiment that might refute string theory. Experimentation in real life based on string theory is still pretty new, with much to discover. Scientists didn't find the particles they were seeking, which means one of a few different takeaways.Coul...
Here is where it can get a little tricky (though, let’s face it, all of string theory is a little tricky). If these strings exist, what are they made of? No one knows. One problem is that the particle (the string) is supposed to be the smallest, most fundamental unit that makes...
Explain String theory. If the string theory is real, then what are strings made of? Has string theory ever been proven? Can the String Theory be proven? What is the string theory all about? What are its achievements? Is it a dead theory? How can I not be skeptical about its feasibilit...
Scientists have found what they say is a link between complex number theory and string theory: a specific kind of elliptic curve from a torus.
The first part is an introduction to conformal field theory and string perturbation theory. The second part deals with the search for a deeper answer to the question posed in the title. Contents: 1. Conformal Field Theory 2. String Theory 3. Vacua and Dualities 4. String Field Theory or No...
M-theory attempts to address these limitations by adding an 11th dimension, along with the concept of membrane, or brane. Like the string, a brane is theorized to be a universal building block that provides the foundation of allmatter. However, unlike the original strings, branes add dimensiona...
However, she also offers a caveat: "Possibly the question to ask yourself is: how much agency am I giving this theory, explanation or belief? Am I allowing it to become part of my own story, acknowledging the power of my own choices and decisions as I do so? Or am I simply letting...
