The Economist View blog of Prof. Mark Thoma speculates on the origin of our universe:
A white hole is connected to a black hole by an Einstein-Rosen bridge (wormhole) and is hypothetically the time reversal of a black hole. Poplawski's paper suggests that all astrophysical black holes, not just Schwarzschild and Einstein-Rosen black holes, may have Einstein-Rosen bridges, each with a universe inside that formed simultaneously with the black hole.Commenter Kharris observes:
The worm that makes this sort of hole...common earth worm, do you think? It would have to be a very large worm in terms of our universe to make a wormhole large enough for our universe to reside within the hole...This made me think. If following the Big Bang we live in an inflationary universe, is the inflation of the US dollar - inevitable? The logical thing to do, then, is to invest in gold.
I always follow the best economists and base my decisions on hard science, that's why I am making money on the bourse.
