This last one is really hard to fathom, and difficult to verify as most people don’t carry a clear awareness of Earth’s place in the galaxy with them, but it seems that the position of the solar system within the Milky Way has changed, from the edge of an outer arm to a branch near the center.
The Hitchiker’s Guide to the Galaxy starts with: "Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun.” This was, as far as most people knew, true. Now, it’s not. In addition, there are now three planets in our solar system with rings, rather than one.
Let us suggest that Earth is not the only place subject to the mandala effect. The implications of this for us, for the sky we see at night, for astronomy and astrology and for the other species we might meet in the future, are as if of yet completely unclear.
