##### X-ray pulses from Cygnus X-1, a celestial x- ray source, have been recorded during high- altitude rocket flights
X-ray pulses from Cygnus X-1, a celestial x- ray source, have been recorded during high- altitude rocket flights. The signals can be interpreted as originating when a blob of ion- ized matter orbits a black hole with a period of 7.84 ms. If the blob were in a circular orbit about a black hole whose ...
