Person interested in physics here. I read somewhere that due to the Heisenberg's uncertainty principle, a particle could theoretically be faster than the speed of light? And if it was faster than the speed of light, could it escape the event horizon of a black hole? Please clarify if I'm wrong but doesn't the speed of an object increase with how uncertain the location of it is?

No. The uncertainty principal is the more certain you are of the location the less certain you are of its momentum and vice versa.

nothing goes faster than light, disregarding exotic manipulations of spacetime itself (locally an object would still be confined to c in this situation).

there are multiple pairs of measurables that obey the heisenburg uncertainty principal, but the relevant and most famous one is position and momentum.

momentum is mass * velocity, and velocity is a vector. so if you know the mass almost perfectly, you have a huge uncertainty on the momentum. assuming for some reason you have an idea of the speed of the object, the uncertainty then affects the mass and direction, rather than giving a chance to surpass c.
