That's right, either the fundamentals are wrong, or this black hole spins on its axis 27 thousand times every minute!

GRO J1655-40 has two powerful jets of plasma rushing away from its poles at nearly the speed of light. The illustration above is said to depict both a polar jet and the surrounding accretion disk. But how this curious reversal of gravity’s influence actually works is not yet clear, the theorists say. Recent investigation has also found that GRO J1655-40 displays an unexpected flickering some 450 times a second. How would the mathematicians respond to something never envisioned by a model that worked only with mass, density, and rotation? Very simply. The hidden black hole must be rotating at an amazing 27,000 rpm, somehow creating an energetic “lighthouse” beam of radiation.
