    Title: Singular Sources of Energy in Stars and Planets

    If primordial low-mass black holes (PBH) exist in the Universe than many of stars and planetary bodies appear to be infected by them. This is also true in regard to the Sun and likely Jupiter and Saturn. The availability of even the very low-mass inner relativistic reactor may lead to essential changes in evolution scenario of a celestial body on its lifetime scale. Black holes in stellar interior may be found either in consequence of captures process or incorporation during the formation of a star from interstellar clouds. Surprisingly that in the equilibrium state a PBH growth is a long-lived process with e-folding rise time of billion years. One can envision a PBH orbiting inside the Sun. Our considerations showed that the PBH experiences very little friction in passing through the stellar matter. If the BH mass is above 10^{-5}M_{sun} the major contribution to the luminosity comes from the relativistic gravitational reactor. In such a case a star evolves towards the Eddington limit. This should lead to considerable expansion of a star and a global stability loss. Microscopic PBHs can exist in the interior of planetary bodies too. To produce the required excess of thermal energy on Jupiter and Saturn the masses of PBH captured are assumed to be reached of 4 10^{19} and 7 10^{18} g, respectively. These microscopic objects are comparable to the hydrogen atom in size. One can envision even a planet with the PBH acting as the self-sufficient source of heating. Such a planet does not need a sun to maintain animal life on its surface. This may last eons.

    I found it out of the ordinary, i am sure i read some thing similar years ago,
    but the idea was shouted down, a google search came up blank.

    Not to worry, Hawkings assures us they evaporate via 'Hawking Radiation'.

    So, when the LHC begins making them in quantity, we'll be OK, right?

    Of course, I've read other theorists who believe they accrete matter much faster than in the referenced paper; i.e. have a much larger cross-section for capture.

    Guess we'll just have to make a few, and find out exactly how long it takes from them to suck up our planet.

    Let's first hope the LHC starts indeed operating, and doesn't get entangled in a jungle of delays, it's start-up has just been delayed until April'08

    I read the paper yesterday, and he uses the word If quite a lot. Seems to me to be very much just speculation, and a kind of exercise.

    The only similar i could find talked about the Bermuda Triangle, may be that is
    what i read years ago.
