    Our Universe at Home Within a Larger Universe?

    ScienceDaily (Apr. 7, 2010) — Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe?

    Such a scenario in which the universe is born from inside a wormhole (also called an Einstein-Rosen Bridge) is suggested in a paper from Indiana University theoretical physicist Nikodem Poplawski in Physics Letters B. The final version of the paper was available online March 29 and will be published in the journal edition April 12.

    Poplawski takes advantage of the Euclidean-based coordinate system called isotropic coordinates to describe the gravitational field of a black hole and to model the radial geodesic motion of a massive particle into a black hole.

    In studying the radial motion through the event horizon (a black hole's boundary) of two different types of black holes -- Schwarzschild and Einstein-Rosen, both of which are mathematically legitimate solutions of general relativity -- Poplawski admits that only experiment or observation can reveal the motion of a particle falling into an actual black hole. But he also notes that since observers can only see the outside of the black hole, the interior cannot be observed unless an observer enters or resides within.....

    this interest me, what if and i say "if" the planets are electrons in a particle and the neuclus is a sun and the shells are belts of comets.

    Wouldn't it make sense, that if we were still inside of some black hole in a greater universe, that the outside universe would have gravitational pull on the contents inside the black hole? Dark energy demystified
