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."

Profound...(All we are is dust in the wind)

To think that the span of a human life is at best about 1/250 millionth of that cycle. Light from distant stars does eventually get here, it just happens on timescales that are beyond imagination.
Such a shame that we occupy such a small blink in the process, and can't witness cosmic events on any larger a level.

Nah, you have it backwards. It is not a shame that our lives are short. I find it inspiring that we have come so far despite this shortness, and we have built instruments that let us actually see all those cosmic events, and even put them in perspective ;)

Psst...it's all the offshoots (I'm looking at you, Baptists) that are causing problems. The Catholic church is rather keen on astronomy an evolution nowadays. Not so much on the gays and condoms, but it's a start.

One man says "it is right to protect the children." The other says "it is right to kill three a day." We should clearly compromise - no more then one child a day, two on weekends!

But seriously. No, we can't. We don't compromise between a fiction and hard fact just because lots of people happen to believe the fiction.
