The sea does not need a hole to exist. The sea is made up of a large body of saltwater that covers a majority of the Earth's surface, forming oceans and seas. It is sustained by various natural processes like precipitation, rivers, and underwater volcanic activity.

A large hole in weak rock near a sea cliff is called a sea cave. This type of coastal formation is typically formed by the erosive action of waves, which gradually wear away softer rock and create a hollow space. Sea caves can vary in size and shape, and are commonly found in areas with coastal cliffs and rocky shorelines.
As someone falls into a black hole, they would appear to slow down and become fainter to an observer outside the black hole. They would eventually appear to freeze at the event horizon due to the extreme gravitational forces, but in reality, they would continue falling towards the singularity at the center of the black hole. Time dilation would make this process appear significantly longer to an outside observer.
If you could view the Earth from every direction without any obstructions, it would appear as a sphere.
No; your pupil is the hole in your eye that lets in the light. Without your eyes being able to receive light, you wouldn't be able to see.
If you were to throw a clock into a black hole, the extreme gravitational pull would distort the perception of time on the clock. As the clock approaches the black hole's event horizon, time would appear to slow down for an observer outside the black hole. Eventually, the clock's information would be lost beyond the event horizon.
