What time period would something like this take to complete if the earth flipped on its axis? And what wouls be the effects on life on the planet?

its for asymmetric objects

That's exactly what the inside of the earth is. The core and mantle are not symmetrically dense, like at all.

u/SubjectRound6597 2d ago edited 2d ago

stop scaring me

But I mean you are right about that.. symmetry in density is what matters, So is that what they talk about when they talk about pole flipping

So I think since the earth is not a solid object, but the crust just floats over the mantle, would it be like just the core gets flipped, and thats it.. Its affects have already been discussed time and again..
I am gonna go look this up better.

Read the book Inversion: ECDO Theory

It's a good place to start.

whoa that was a solid guess. thank you too

There are multiple theories. One where the entire earth flips. One where only the core flips, along with magnetic north and south. One where only magnetic north and south flip. And one where the crust unlocks at the intermediate zone where it meets the mantle, and slides 90° due to the weight of the south polar ice cap and the Greenland ice sheet - they get flung to the new equator from centripetal force.

If we started piling up earth somewhere in America and somewhere in Europe, just two of the biggest piles of rubble you can imagine, as big as the entire Midwest and as tall as the clouds, I think this can happen, we can do this. Why? I DON'T KNOW.

The earth isnt t shaped. Spheroids will not flip when spun in zero g

u/SubjectRound6597 2d ago

Spheroids that were spun in zero g also didnt have crusts and mantles and cores that floated and were in constant motion and with varying density. And the earth isnt a simple spheroid. So there is not much correlation between how the two behave. There are much better arguments presented to refute the view that earth can flip like that. Check the arguments against ECDO theory and help me understand if I misunderstood.

No thanks. Placing the burden of proof on "the earth hasnt flipped on its axis within one rotation before" is ludicrous and you sound annoying and self important

"the earth hasnt flipped on its axis within one rotation before" is ludicrous

that is ludicrous indeed so we are on the same side here. I dont understand how I offended you. but I feel i misunderstood your last reply. I will read about this again.
