Is there any exception of laws of gravitation?

Answer 1

It seems mysteriously so, yes: I highly recommend investigation of The Oregon Vortex, whose website is accessed via the related link below:

Answer 2

One exception is at the quantum level, where gravitational effects are often overshadowed by other fundamental forces like the strong and weak nuclear forces. In extreme conditions such as black holes or the Big Bang, the laws of gravitation break down as they interact with other physics theories like general relativity and quantum mechanics.
