String theory standard model
WebUnlike supergravity theory, string theory was able to accommodate the chirality of the standard model, and it provided a theory of gravity consistent with quantum effects. Another feature of string theory that many physicists were drawn to in the 1980s and 1990s was its high degree of uniqueness. WebMar 28, 2024 · “This is definitely a step forward in demonstrating that string theory gives rise to many solutions with features of the standard model,” says string theorist …

WebString theory's claim that all molecules are strings of energy has drawn harsh criticism. There are many versions of string theory, none quite successfully predicting the observational data explained by the Standard Model. M theory is now known to have countless solutions, often predicting things strange and unknown to exist. WebThe argument is based on the typical occurrence of (a) hidden sectors, and (b) interactions between the standard model (visible) sector and these sectors. These suggestions necessarily refer to string or M theory, reaching for “hidden sectors” that may never be seen or detected, or new dimensions, that may never be seen or detected. Current ...
