Voyager 1 Passes 100 AU from the Sun 326
An anonymous reader writes "Yesterday, Voyager 1 passed 100 astronomical units from the sun as it continues operating after nearly 30 years in space. That is about 15 billion kilometers or 9.3 billion miles as it travels about 1 million miles per day. Scientists still hope it will find the edge of the solar system and get into interstellar space."

Could you amend that to read, "is not consistent with our current understanding of gravity" or "is not consistent with our apparently flawed gravitational laws"?
Really, I wish they would stop calling these things "law". Every generation sees a bushel of these "laws" being thrown out, adjusted, or ignored.
The Universe doesn't play by our "laws", it just waits until we understand Its LAWS.

By the year 2040, the prediction/projected cumulative amounts released by coal burning plants is
U.S. release (from combustion of 111,716 million tons):
Uranium: 145,230 tons (containing 1031 tons of uranium-235)
Thorium: 357,491 tons
Worldwide release (from combustion of 637,409 million tons):
Uranium: 828,632 tons (containing 5883 tons of uranium-235)
Thorium: 2,039,709 tons
Anyways, back to the subject at hand, why can't we make the radioisotopes now in nuclear waste facilities (especially in the Yucca Mountain range in Nevada) produce energy using a RTG? It may not be the most efficient method but the stuff is just "sitting" there and can't be used in a traditional power generation method.
Just a thought. It might at least be able to power the lighting systems at those facilities.

Are there any photos of the sun from that distance? I've never seen photos looking back at the solar system from those spacecraft published. Even if it is only points of light, it'd be neat to see some photos from Voyager with the sun and visible planets highlighted to get some sense of scale of our tiny corner of the universe.
