In a paper to be published this week in the journal Science, University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought. A 40-mile-wide black hole 8,000 light years from Earth named V404 Cygni yielded the first precise measurements of the magnetic field. Study authors found the magnetic energy around the black hole is about 400 times lower than previous crude estimates.
