Solar System Date of Birth Determined
Invisible Pink Unicorn writes "UC Davis researchers have dated the earliest step in the formation of the solar system — when microscopic interstellar dust coalesced into mountain-sized chunks of rock — to 4,568 million years ago, within a range of about 2,080,000 years. In the second stage, mountain-sized masses grew quickly into about 20 Mars-sized planets and, in the third and final stage, these small planets smashed into each other in a series of giant collisions that left the planets we know today. The dates of these intermediary stages are well established. The article abstract is available from Astrophysical Journal Letters."

I'd like to thank you for providing me with the single most defensive response to attempted humor I've ever seen.
