Diamonds and precious metals found in the eastern United States might have rained down during the last Ice Age after a comet shattered over Canada and set North America ablaze, all leading to a mass die-off of animals and humans.
New chemical analyses of diamond, gold and silver found in Ohio and Indiana reveal the minerals were transported there from Canada several thousand years ago. The question is, how?

LOL. Sorry, comet explosions are good.
"Scientists began to seriously ponder the presence of diamonds in space in the l980s, when studies of meteorites that crashed into Earth revealed lots of tiny nanometer-sized diamonds. Astronomers determined that 3 percent of all carbon found in meteorites came in the form of nanodiamonds. If meteorites are a reflection of the dust content in outer space, calculations show that just a gram of dust and gas in a cosmic cloud could contain as many as 10,000 trillion nanodiamonds."

And will the Pangeans want it back from them?

Comet Lucy.
Do you know that if you could run around in a circle fast enough, you would move ahead in time? It's true. Moving ahead in time merely involves acceleration, which in turn requires energy. And in this case, a nearly impossibly large amount of it. Acceleration is defined as a change in speed and/or a change in direction (running in a circle really fast).
So maybe Arthur C. Clarke was right after all..
Bush’s fault??
Ah, the young!
Reminds be of a book I read in school. I believe it was H.G. Wells. about a meteorite that was gold or a large portion and the fear was it would wreck the world’s gold standard economy.
It does make you what wonder minerals are out there, known and unknown.
One thought, if diamonds are carbon and oil is too... I wonder if there are Martian oil sheiks?
Climate change is a win/win for Ohio. If it gets warm Dayton could become beach front property. If it gets cold and the glaciers come back there’s diamonds for everyone.
No, this wasn't an earthquake. ;-)
It is true, that if you change your speed and/or your direction at a fast enough rate you would move ahead in time (age at a slower rate than your stationary surroundings). But in order to change your speed and/or direction (leave the inertial state), you need to apply energy. However, to change either your speed or direction at a fast enough rate to make a noticeable difference, it would take an unrealistic amount of energy. Still, it is possible, and has actually been proven in experiments involving astronauts and airplane pilots -but only to millionths or billionths of a second differences.
Why does time change?
Ever feel like time moves very quickly and sometimes very slowly? Like how the hours fly by when you're hanging out with a close friend, or how seconds drag on endlessly when you're stuck in traffic on a hot day? But you can't actually speed time up or slow it down -it always flows at the same rate, right?
Albert Einstein didn't think so. His idea was that, theoretically, the closer we come to traveling at the speed of light (186,000 miles per second), the more time would appear to slow down for us from the perspective of someone who, in relation to us, was not moving. He called the slowing of time due to motion time dilation.
Imagine you're standing on Earth holding a clock. Your friend is in a rocket zooming past you at nearly 186,000 miles per second. Your friend is also holding a clock. If you could see your friend's clock, you'd notice that it seems to be moving a lot more slowly than yours. Your friend, on the other hand, thinks the clock in the rocket is moving just fine, and it's your clock that seems to be moving more slowly. Sound confusing? Well, remember, it took Einstein years to figure this out, and he was pretty smart (see Genius Among Geniuses).
The twin paradox
Einstein came up with an example to show the effects of time dilation that he called the "twin paradox." It's a lot like the Time Traveler game you just played. Let's try it out with a pair of pretend twins, Al and Bert, both of whom are 10 years old in their highly futuristic universe.
Al's parents decide to send him to summer camp in the Alpha-3 star system, which is 25 light-years away (a light-year is the distance light travels in a year). Bert doesn't want to go and stays home on Earth. So Al sets out on his own. Wanting him to get there as quickly as possible, his parents pay extra and send him at 99.99 percent the speed of light.
The trip to the star and back takes 50 years. What happens when Al returns? His twin brother is now 60 years old, but Al is only 10 and a half. How can this be? Al was away for 50 years but only aged by half a year. Has Al just discovered the fountain of youth?
Not at all. Al's trip into space lasted only a half year for him, but on Earth 50 years passed. Does this mean that Al can live forever? Nope. He may have aged by only half a year in the time it took 50 years to pass on Earth, but he also only lived half a year. And since time can slow down but never goes backwards, there's no way he could grow younger.

I always felt that Hudson Bay was formed by either an asteroid or a comet.
How ‘bout flood drainage?
Looks like that time-travel Tiffany's heist didn't work out.
The conservation of energy is a fundamental concept of physics along with the conservation of mass and the conservation of momentum. Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. Energy can be converted from one form to another (potential energy can be converted to kinetic energy) but the total energy within the domain remains fixed.

note: the actual crater, unfortunately, is buried ~1,000 feet beneath the mountain -the impact occurred around 380 million yrs ago and has long since been buried by sediments that washed off a long ago eroded away alpine-like mountain range which once stood where the Taconic Parkway is today-etl
Google Maps: Panther Mountain Crater in Upstate NY:
(it's the circular feature to the upper left of the two small bodies of water (one is the Asokan Reservoir) To further help identify it on the Google map, it has a little white 'route-28' sign along its northern 'rim'(the actual rim is buried ~1,000 ft below).

Here's a contour map of the same area from wikipedia.(but also check out the neat Google image above)
