Bubbles


Artist's image (not a telescope photo) of two enormous bubbles of gamma-ray emitting material discovered above and below our Milky Way. They were discovered by NASA's Fermi Gamma Ray observatory and extend about 25,000 light-years from the galactic plane. The bubbles are estimated to give off the energy of 100,000 supernova explosions. Astronomers are not sure what is giving off the gamma rays, but these bubbles could contain millions of tiny Black Holes. The Universe is far stranger than we imagine.

I have made some amateur posts on that phenomen.

and a survey in literature

These kinds of shortlived gamma bursts are seen also elsewhere. Maybe some imbalance between matter and antimatter formation?

What happen if we have a black hole at the center of Earth?

HI ulla: Thanks for the links and for following these posts. If Earth contained a tiny Black Hole, it would be too small to ever swallow us up. The tiny amount that it did consume would be largely converted to energy. Outward pressure from radiation would balance gravity's inward pull.

Earth would have a hot core, and a magnetic field that was not necessarily aligned with the geographic poles. Makes one think, does it not?

I actually thought of the same reaction, a giant gamma burst, at the center of Earth. What would happen then? Maybe a reversal? Or an expansion?

If that center is not actually in the middle it would have a greater impact? Jerry Decker said the magnetic axis don't go through the center of the Earth exactly.

the milky way galaxy bubbles and electron p orbitals, both have dipolar lobes that are dumb-bell shaped. fractal cosmology shows an atomic nucleus is likely self-similar to our galaxy. gamma rays are produced in atomic nucleus when electric field is disrupted. EM forces can explain jets and rays, black holes and dark matter is fictious and not required except to keep the big bang going.
