I'd really enjoy seeing integration with Google Street view (where possible), to modify the terrestrial panorama, as the foreground for what the user might expect to see on the ground, for any given pin dropped on the map.

It starts the viewing on Null Island (0 Lat / 0 Long) when geolocation is refused, so the grassy farm field is cool, but it's be neat to pull the view into cities, to see what the sky would look like, if the light pollution weren't getting in the way.

Serious question: Doesn't it seem to be a deep and cutting flaw, that an entire branch of physics attempts to draw conclusions about subatomic behavior based on the macroscopic interference noted when photons pass through polarized sunglasses, or perhaps electrons travel through the diffraction grating of a cathode ray tube?

It seems fundamentally incorrect to show hobbyists and laymen these partial examples, and then cross ones arms and say "that's the way it is" and venture no further.

Polarization experiments and the double slit experiment are continually hauled out onto the stage, again and again, and never enlighten anyone. Taking a relativistic particle, and shooting it through or bouncing it off of a standing wall of atoms (e.g. polarization filters and diffraction gratings), doesn't really introduce an air of mystery into anything, because the wall of atoms operates its own subatomic state, which is selectively ignored. It's basically like setting a murder mystery inside a super max prison.

At a diameter of 250KM, and with enough gravity to retain rings, does that mean it also possesses enough gravity for hydrostatic equilibrium?

If so, this qualifies it officially as a dwarf planet.
