In summary, the conversation discusses the idea of using a bathtub to demonstrate the effects of gravity on a planet like Saturn. It is suggested that if the planet were placed in a large enough bathtub, it would collapse into a star or white dwarf. This sparks the idea of creating an animated video to further explore this concept.

As a fun teaching tool for several areas of math and science, imagine that happening. The planet floats in water. What happens next and how does it look? Has anybody thought this through and made an animated video?
First fill your tub to about the 50,000 mile mark. Surprise: most of the water turns into exotic high-density ice, due to the enormous hydrostatic pressure (assuming you have gravity, which you need to keep the water in place.) This happens even if the water’s boiling hot.
So Saturn starts off sitting high and mostly dry, unless you crank your gravity down a lot.
So in it (he?) goes. Briefly we’re distracted by the gorgeous shooting-star effect of the rings and the dozen or two moons burning up in our air and making incandescent splashes as they plunge to their own tiny dooms.
Around the planet a tidal wave higher than Earth rises and radiates outward. Then we see all kinds of fizzing, bubbling and popping, on a majestically slow (planetary) scale. A shock wave of mist swells outward, moving at the speed of sound in the gas and taking hours to envelop the planet. I suppose eventually we're left with the stone core.
Somebody should explore this idea further!

Saturn floats in a big enough bathtub, but leaves a ring.

Hypothetically, if we could find a tub big enough to float Saturn in, it would collapse under its own gravitational pull into a star or white dwarf depending on the SM (solar mass) of the tub and the water.

Interesting idea though godwinfh
 

Related to If Saturn floats, then what happens?

1. What would cause Saturn to float?

The density of Saturn's atmosphere is less than the density of water, which would allow it to float if it were placed in a body of water.

2. Would Saturn float in any body of water?

No, Saturn's atmosphere has a specific density and composition that allows it to float in water, but this may not be the case in other liquids or bodies of water with different densities.

3. How does Saturn's density compare to Earth's?

Saturn's density is much lower than Earth's, which is why it is able to float in water. Earth's density is significantly higher due to its solid rocky core.

4. Is Saturn the only planet that can float?

No, Jupiter is also known to be able to float in water due to its low density atmosphere. Other gas giants like Uranus and Neptune may also have the ability to float.

5. What would happen to Saturn if it were placed in water?

If Saturn were placed in water, it would float and maintain its shape due to the surface tension of the water. However, over time the water would start to evaporate and Saturn would eventually sink as its density is slightly higher than that of water vapor.
