White holes are similar to black holes except white holes are ejecting matter verses black holes are absorbing matter. In 1916, Karl Schwarzschild derived the first model of a black hole using Einstein's theory of general theory of relativity. Nothing, not even a particle moving at the speed of light, can escape the gravitational pull of a black hole. The existence of white holes is implied by a negative square root solution to the Schwarzchild metric for space-time-matter continuum.. It is important to remember that black and white holes can be composed from matter or antimatter.
A worm hole, which joins white holes, is known as the Einstein-Rosen bridge and is one of the most fascinating concepts in theoretical physics. In 1962, John Wheeler discovered the Einstein-Rosen bridge space-time-matter metric. Theoretically, a worm hole could be stabilized to allow a safe equilibrium between matter and antimatter white holes. To stabilize the worm hole, the throat of the singularity contains matter and antimatter white holes, which are spherical in nature. The antimatter has a negative mass and exerts a positive surface pressure.
Scientists have questioned the existence of black holes for decades. On May 27, 2004, Edward Churchwell, a University of Wisconsin-Madison astronomer, announced their findings using NASA's Spitzer Space Telescope that the Milky Way Galaxy was churned out hundreds of new stars. The black holes in the center of galaxies are composed of condensed matter and antimatter. The black holes have the mass of a billions of suns. The Einstein-Rosen Bridge keeps the matter and antimatter black holes separated. The oscillations between the black holes at opposite ends of the wormhole force the black holes to become white holes that eject matter and antimatter in opposite directions forming the spiral arms of stars within the galactic disk.
The antimatter negative mass ensures the throat of the worm hole lies outside the protected region and the positive surface pressure prevents the throat of the worm hole from completely collapsing. The matter and antimatter properties are not arbitrary or purely theoretical for producing a stable worm hole. Einstein's equations specify what the energy-momentum content of matter must be in an area to produce the needed geometry. Matter and antimatter white holes can stabilize a worm hole.
