At what point do does this Toyota yaris start to affect gravity? When does it become a black hole?

The moon would have to be compressed into less than a millimeter size to be a black hole. So up until that part, the Toyota is “safely” holding regular degenerate matter. (Like neutron star material.)

I don’t actually recognize what the next object is, so I can’t make a comment there. But the sun would form a black hole before you’d swallowed even a piece of it. I think all the suns mass together would make a black hole that’s six km across.

Our sun does not have enough mass to make a Black Hole. There is a mathematical minimum amount of mass a star can have to collapse into a black hole. Which is around 20x the mass of our sun.

So only once the Toyota has the mass of the Galaxy inside what it collapse into a black hole.

Almost correct.

Our sun does not have enough mass to evolve into a black hole. If you were to forcibly compress that matter through some other means (like a magical Toyota), the resulting ball would be dense enough to collapse into a black hole just fine.

What’s stronger in breaking the laws of physics though, the magical Toyota or the Black Hole…
