What? Could this explain It?

Rings of Uranus in striking change
Strange things are happening on the rings of Uranus. Once every 42 years, the planet's tilted angle lets earthbound observers briefly catch three edge-on views. The time for rare views is right now and a team of astronomers has seen some dramatic changes. Some rings are growing brighter, one is fading away, and another is new or unexpectedly moving outward from Uranus. At the same time, a broad diffuse cloud of microscopic particles seems to be pervading the entire ring system.
The changes are not fully understood [heheh]. Imke de Pater, a UC planetary astronomer, has been studying Uranus for 20 years. "The ring system looks completely different from the way it did 21 years ago," he says. "The rings are exquisite now".
The zeta ring is now 25,000 miles out."It's possible", De Pater said, "that incoming meteorites disturbed the ring and thrust it outward. He suggested that some massive object may have crashed into the surface of Uranus and ejected a shower of dusty debris that has formed an entirely new ring, while the old zeta ring has simply faded."

Remember when Comet Shoemaker-Levy slammed into Jupiter a few years back? This reminds me of that. I have no doubt that there's always something going on out there in the solar system, that we're barely registering in our relative infancy.

Maybe we're still in gestation.

So we worship these crippled human representations of the species in our celebrities and leaders. If we were asked to send a representation to outer space that the human species was proud of, do you think our choices would be different?

Uranus another protective gatekeeper?

Then there is this stunner a void in the universe devoid of even black matter.
a big cold gaping hole just SW of Orion.

Ha! How's that for negative space? Gives us the go-ahead, I believe.

How Zen of the universe.
