I have read that gravity is always attractive.
However, frame dragging, or the gravitational effects of spinning matter, is used to explain jets of energy/particles that shoot out of spinning black holes and quasars.
If gravity is always attractive, then why do these jets shoot out from the black hole?
It seems that the spin of the black hole is negating the black hole's massive gravity, and allowing the jets to escape.
Can anyone explain this?
Thanks,
