How the fuck can a planet tip over on its side? What does that even mean in space?

>> No.15302310

do u know what an axis of rotation is?

In Uranus' case (giggle), longer lasting seasons with more extreme weather.

It all started with a shifting mass on the poles.

It was just hit by another planet sometime (absorbed). Systems with more bodies are more unstable than such with few, and such fuckery was a method to reduce this number.

Hope this helps. Uranus never "tipped over", it was spun along a different axis due to a giant impact event.

the text would say otherwise that the magnetic pull of the space has entropic turn on it

That's what happened last with me and your mum.

That's not what happened, Uranus doesn't approximate a T shaped mass. >>15304879 is correct, the momentum of the impacting mass dominates over the preexisting angular momentum of the planet before impact.

did it also turn into a orange ball of awesome like when Theia crashed with Earth and liquified the entire ball?
