AI Thread Summary
If a superstring's vibration is stopped, the discussion suggests it may not cease to exist entirely, as string theory accommodates massless, nonvibrating strings. Some participants argue that the properties defining existence, such as mass and charge, are linked to vibration, raising questions about the existence of nonvibrating strings. The conversation highlights that certain string states in superstring theory can exist without vibrational modes, including massless states and nonvibrating tachyonic states. This indicates a complexity in string theory that allows for the existence of strings independent of their vibrational state. Overall, the relationship between vibration and existence in string theory remains a nuanced topic of exploration.

Hello, this is my first post on the forum. I have merely one quetsion... if one were to "hold" a superstring, that is, to prevent it from vibrating, what would happen?

I believe it would cease to exist. AIUI, superstrings are made of nothing other than their own vibration. At least, that's the most popular theory ATM.

EDIT: Welcome to the Forums!

String theory allows massless nonvibrating strings.

I have never heard that before. Not to hijack the Topic, but now I simply must know more.

I thought string theory proposed that all of the properties that constitute "existance" i.e. mass, charge, spin, et al were caused by the vibration. If a superstring is not vibrating it ceases to have any properties, does it not? If it has no properties, how can it be said to exist?
 
String mass and transformation properties under spacetime supersymmetry (i.e. "spin") have a dependence on vibrational degrees of freedom while yang-mills charges don't, they simply sit at the ends of open strings.

The ground states of the R-sector (Ramond sector) of the unoriented type I open plus closed superstring theory, and the R-R sector in the type IIA and IIB superstring theories are massless string states that include no vibrational modes.

There are also nonvibrating tachyonic states.

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
