Singularity

If SpaceTime is not continuous inside a black hole, then the concept of a singularity inside a black hole goes away.

What is "in" a black hole? Not SpaceTime. Nothing. Less than nothing. No movement of time. No space. No light. No energy. Physics deals with what goes on in SpaceTime. So it can say nothing about what is  "inside" a black hole. All it can say is what it can't say.

Everything that "makes up" a black hole is gathered at the circumference; at the event horizon. All those things that are gathered at the event horizon tear a hole in SpaceTime. SpaceTime is not  strong enough to keep from being torn.

To the extent that Swiss cheese is not continuous, it is a nice model for SpaceTime. Of course, it is hard to grock that SpaceTime is not continuous, but --- it's not.

Science has no data past the event horizon. Past that is all conjecture.

Heating the ocean

7. Heating the ocean
1.35 billion cu.kilometers is the volume of the ocean (wikipedia)
1 billion metric tones is the weight of 1 cu.kilometer
Weight of the ocean is:
[1.35 x 1000**3] cu.km x [1000**3] m.tons
is [1.35 x 1000**6] metric tons, 1.35 quintillion metric tons
heating the ocean 1C
specific heat of water is 1 calorie per gram C
1000 calories (kilocalorie) per kilogram C
1000 kilocaloriws per metric ton (1000 kilograms)
[1.35 x 1000**6] metric tons x 1000 kilocalories/m.ton
[1.35 x 1000**7] kilocalories / degree C
Each hour the earth receives 430 quintillion joules from the sun
1 joule =.239 calorie
multiplying is 102 quintillion calories, about 100 quadrillion kilocalories (per hour)
