If you in case a black hole in sphere will it neutralize?

every object in the universe with "mass" is a hole in space... with very steep "sides". The earth is a hole, the moon is a hole, the sun is a BIG hole... if you stand too close to the edge of the hole, you will fall in.... and end up at the bottom of the hole. The hole doesn't have any "sides" that you can cling to, so to get out of the hole, you need to launch or accelerate yourself up and out of the hole..... if you DON'T reach escape velocity, you fall back down the hole.... a "black hole" is just a hole whose gravity is SO strong, whose sides are so steep, whose depth is so great, that not even Light has enough velocity to escape it.
