Would such a flip be important? It could get very serious – like the time a couple of hundred million years ago when all the continents were combined into one big continent called "Pangaea"—if the Earth’s rotation axis flipped such that this one big continent became a polar continent like Antarctica. So, it would appear that a moon is required for a stable planet with life. Non Sequitur. Life exists just fine in the Antarctic (and if all the land on Earth were combined into a polar continent, at least some of the coastline would be further from the pole, and thus in a milder climate, than that of Antarctica).

In about 50 billion years. The Sun will have gone Nova long before this. I didn't think stars the size of the sun went nova.

Well, it doesn't nova, it disperses into a 'planetary nebula' with the remains shrinking to a white dwarf.
Where it will fade to a black dwarf.
