text: For a rotating black hole, this effect is so strong near the event horizon that an object would have to move faster than the speed of light in the opposite direction to just stand still.
text: As was emphasized above, quantum gravitational effects are extremely weak and therefore difficult to test.
text: Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics, and where quantum effects cannot be ignored, such as in the vicinity of black holes or similar compact astrophysical objects where the effects of gravity are strong.
text: Near a black hole, such tidal effects can be very strong.
text: As explained above, quantum gravitational effects are extremely weak and therefore difficult to test.
