2) ich glaube nicht, dass Heim eine solche Aussage macht.

Hab jetzt hier auf der Arbeit die Bücher nicht zur Hand - aber dies hier sollte auch reichen:

IGW-Resch-Verlag (EHT - Publications) -> AIAA2005-4321-a4.pdf (oder nach "AIAA2005-4321-a4.pdf" googeln...):

Heim performed a phenomenological derivation and obtained the factor ¾ pi.

Any physical phenomenon requiring a gravitational constant G' < G or a speed of light c' > c in
R4 therefore has to be ruled out, violating the fact that T is the minimum surface. On the other hand, because of positive gravitophoton action, phi is actually reduced. In order to resolve this contradiction, it is postulated that the object has to leave our spacetime and enters into a parallel space (or parallel universe or multiverse), denoted as R4(n) with n element of |N. It seems to be possible that a spacecraft, under certain conditions, stated below by Eq. 12, will be able to enter into such a parallel space. Covariant physical laws hold in parallel space R4(n) with respect to R4, but the gravitational constant, the mass of the spacecraft, and the speed of light are changed according to G(n)=G/n, M (n)=nM, and c(n)= nc where n is larger than 1. In such a space, superluminal speeds would be possible in principle. The interesting fact is that an object can transit into parallel space at a relatively low speed from our own spacetime R4, so no excessive energy input is needed.
