What would happen if the Earth turned 180 degrees?

[Gingerbread Demon]

I sense the makings of a Space:1999 episode

Yep why not?

They finally make it home back to Earth only time has changed due to relativity and the Earth has done a 180

By the way, flipping the earth would require a large change in its angular momentum. The earth is like a gyroscope. Try flipping a spinning toy gyroscope over by hand to get an idea of the significant force that would be required.

Easier if you initiate the turn 90 degrees spinwise from the axis you're trying to turn, in which case it's actually EASIER to flip the gyroscope. You ca actually spin the whole thing with just a tiny flick of the wrist.

Ah, yes, that's quite true. You need to apply the couple in a non-intuitive manner.

I saw the title of this thread...

...and I was like: "Night?"

This involves a 90 degree shift, so double as necessary:

Also sprach Heinlein.

^ This is a shift along another dimension, not angles.

Details.

Euclidian dimensions are orthogonal and a 90° angle must exist beween them.

Makes sense as it's reckoned that the moon stabilises the earth's axis of rotation.
