Scientists Calculate the Moon To Be 4.51 Billion Years Old (go.com)
Scientists used rocks and soil collected by the Apollo 14 moonwalkers in 1971 to calculate the age of the moon. It turns out that it is much older than scientists suspected, coming in at 4.51 billion years old. ABC News reports: A research team reported Wednesday that the moon formed within 60 million years of the birth of the solar system. Previous estimates ranged within 100 million years, all the way out to 200 million years after the solar system's creation, not quite 4.6 billion years ago. The scientists conducted uranium-lead dating on fragments of the mineral zircon extracted from Apollo 14 lunar samples. The pieces of zircon were minuscule -- no bigger than a grain of sand. The moon was created from debris knocked off from Earth, which itself is thought to be roughly 4.54 billion years old. Some of the eight zircon samples were used in a previous study, also conducted at UCLA, that utilized more limited techniques. Melanie Barboni, lead author of the study from the University of California, Los Angeles, said she is studying more zircons from Apollo 14 samples, but doesn't expect it to change her estimate of 4.51 billion years for the moon's age, possibly 4.52 billion years at the most. The study was published today in the journal Science.
He created it 6000 years ago. Read a book!
Giant impact theory gets bonus points.
Harrison's Postulate - "For every action there is an equal and opposite criticism"
This will probably get me downvoted as a troll but I've begun to drown out the following: 1. New Moon Formation/Age Theory 2. New Dinosaur Extinction Theory 3. New Asteroid On Possible Future Collision with Earth Estimations 4. New Solid State Physics Miracle that Promises Amazing Possibilities 100 Years in the Future. They just seem to disappear and are never heard from again or become part of the background noise of science.
This is going to confuse the hell out of poor old Ken Ham
Couldn't the 4.6 billion years old stuff just have come from a 4.6 billion years old original source (say, Earth), while the moon still came into existence only, say, several hundred million years ago, having been formed out of something which perchance included that stuff?
this is all a guess, they actually have no idea.
If it asks, I say it doesn't look a day over 4 billion. After all, the moon is a harsh mistress.
Trump wants to make gay marriage illegal, I expect he will make Uranium-lead dating illegal too.
For the Moon to have originated from the Earth there would have to have been an enormous collision to launch the Moon chunk away from the moon, and then that moon chunk would have to have had a very, very lucky second collision with something else perfect enough to place it into a circular orbit around the Earth.
Obviously (to me anyway) the Earth and the Moon formed from a swirl of stuff which formed into two planetary bodies.
Wow! I'll sleep better at night!

I think we should probably think about getting a new one some time about now.

You sure he gets paid for that?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
I thought moon dust built up at 1mm/1000 years , thus 4.5B years would 4500m thick??
What gives?

What about it being Hollow?
...I learned from watching "Creature From the Black Lagoon." That movie has surprisingly accurate science for a Universal monster flick. Double-checking fossil age estimates against the surrounding rock. Whoa, I didn't catch that when I was eight! The leading-man "good guy" scientist is searching for additional information about the transition from water-breathers to air-breathers in the evolutionary record for tidbits that could prove useful in adapting the human body for deep-space exploration.
What if the sample were from earth... that would explain why they both have the same age...?
or extrapolate, or whatever. "Rock" and "soil" are not complete sciences, we can only speculate and extrapolate when attempting the feeble effort of estimating its age, because, again, everything we know about rock and soil formation is based on speculation.
"Previous estimates ranged within 100 million years, all the way out to 200 million years after the solar system's creation, not quite 4.6 billion years ago." is misleading. It sounds like before this research we had no clue. Scientific consensus has been that it's roughly 4.5 billion years old for decades now. As a lazy check, the Wikipedia article on the moon has stated the 4.5 billion figure based on a source from NASA since September 2002, and likely wasn't in there previously because Wikipedia was pretty new at that point. This research dials in the precision and provides independent confirmation.
How could they determine that the rocks collected from the surface were actually from the moon and not from meteor bombardment? Did they dig into the ground more than the estimated 15 feet of regolith to get their samples?

Creationist much?
If you make a cake with 4.5 billion candles, and each candle was 1 lumen; it would give off 4.5 Gigalumens.
If the full moon lights the earth with 0.1 lux (I have found several values, but this one will do) then I calculate the moon reflects the equivalent of 50 Gigalumens. This is not quite your classical lumen, which gives off light in all directions, but that's only a factor of 2.
So the cake would be 9% as bright as the full moon.
No no, please don't end that with an ellipsis. Finish your thought there. What is the next thing he should say? Maybe:
Well, guys, we really don't know this. Be a little more humble. We should stop having a scientific debate about it. - said a scientist that should be fired
Well, guys, we really don't know this. Be a little more humble. We should just give up trying to figure it out. - said a scientist that should be fired
Well, guys, we really don't know this. Be a little more humble. We should stop taking data and go with our last answer. - said a scientist that should be fired
Well, guys, we really don't know this. Be a little more humble. We should listen to what our religious leaders say. - said a scientist that should be fired
Well, guys, we really don't know this. Be a little more humble. We're incapable of knowing this at all. - said a scientist that should be fired

Scientist don't make tons of money, so I am not sure what you are trying to say.
