Supergravity in 4 Dimensionss. After that, we will count degrees of freedom, in order to see what supergravity models we can have. After defining the vielbein-spin connection formulation of gravity, within which supergravity is defined, we will finally define the model of . supergravity.

Relativistic Stringsy represent an idealization, and have zero thickness, i.e., they are truly one-dimensional, and moreover their endpoints will move at the speed of light. But like them, will be characterized by a certain string tension, or energy per unit length, ..

,Möglichkeiten der Zieldeterminierung,as of standard candles, so to understand that we will discuss shortly stellar evolution, and the possible stellar objects we can have. We will then classify the various measurements of distance, followed by possible determinations of mass of stellar objects.

,Möglichkeiten der Zieldeterminierung, dimensional space is really small, they would be unobservable. Perhaps the size is comparable to the Planck length ., which would be natural in a quantum gravity theory, or maybe otherwise larger, yet still small.
