Unfun rational answer:

- The satellites used to generate the Google Earth imagery are sun synchronous satellites. They never pass over the poles. Spot is in a 98.7 degree orbit, Landsat, 98.2. Any imagery of the poles from those satellites is going to be of low resolution and distorted. You can see this loss of resolution start to kick in at around 80 degrees north and south.

- The algorithm Google uses has some obvious problems at the poles, the south pole in particular. I suspect a mathematical singularity in their internal representation schemes at the poles.

- Google tries to mask out clouds by stitching together multiple images. Clouds are white. So is ice. Google has a hard time with ice sheets because its cloud filtering algorithms masks out the data.

"They" don't want us to know that there are penguins at the North Pole and polar bears at the South Pole.

I believe I read Google gets its satellite imagary from a few sources and does not depend on one supplier.

Some of this may be true, but what is also true is that some areas they manage to capture really quite well so unless this cloud software is selective to different areas, I dont think this can be the real answer we need.

The other thing which has been overlooked is that not all areas are white because there are quite a few areas of rocks/mountain/hills and which are uncovered. There are even some unfrozen lakes and hot spring areas which are thawed in the antarctic summer.

So, although that was a nice try by DH Staff Emeritus Science Advisor it does not quite stand up to reality.

There’s another theory that’s just like hollow earth, instead of people standing the other way from us on the inside, there’s a area where there’s people standing the same way we are and there’s a gap with water and land. Then there’s a lot of tunnels going to the area. Some people just think there’s only tunnels and it’s not all the way hollow.
