    Notes: [Auszug] The purpose of this note is to point out that near the singularity quantum effects are important and may permit unlimited communication near 2 = 0, even in the Robertson-Walker form. There have been many different approaches to a quantum theory of gravitation. Here we adopt Feynman's path integral ...

    Dust in Supernova Explosions (1970)

    Notes: [Auszug] We discuss here the possibility that a significant fractionsay 10 per centof the mass of these heavy elements condenses into solid particles during the expansion phase following explosion. Besides producing observable effects on supernova light curves, such solid particles could make a significant ...

    Notes: [Auszug] PROF. GAMOW appears to agree with our view that accretion of hydrogen by the stars from the cosmical cloud would be important if the rate were sufficiently rapid to compensate the transmutation of hydrogen within the stars. He believes, however, that the accretion rate is too low for this to be ...

    Notes: [Auszug] The Euclidean behaviour for source counts between 10 and 103 sr"1 can be understood on the basis that the sources in question are not at significant cosmological distances. This explanation can be used either for the steady state model or for non-evolving Friedmann models. The opposite point of ...

    The Mass Difference of the Muon and the Electron (1972)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The fact that the muon and the electron have different masses can be understood in terms of a Machian theory of inertia. The masses of particles are not fixed and immutable but depend on the detailed particle composition of the ...

    Notes: [Auszug] The increasing number of observations of discrepant redshifts means that no longer can these be passed off as chance juxtapositions. A possible explanation of the data is given here in terms of a theory that incorporates a gravitational “constant” that is decreasing with ...
