    Mysterious spheres

    What do you think---natural formations or man made?

    My vote goes to natural geology but it would be nice to have one in the garden. If we found one still in its bowling bag I might have to change my mind.

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.

    Looks like it has layers of material on it's surface. Giant pearls made by giant prehistoric oysters? Shellfish humor...

    How big would a trebuchet have to be to launch one of those?
    Depending on whom you ask, everything is relative.

    Could be an accretion layer flaking off?

    The article mentioned the spheres in Costa Rica, Olmec relics according to a theory I heard. Anything new on those?

    Big enough to throw it? /silly

    Such a trebuchet would have to be built from metal, I think. I'd love to watch the first test ... on Youtube.

    Could be similar to the naturally formed "cannon ball" rocks found on some beaches in New Zealand.

    A meteorite that large would have made one heck of an impact if it was that size when it hit.

    Almost certainly a concretion, albeit a big one, opines a paleontologist and science writer for *Forbes magazine:

    There are many examples of spherical concretions like the one found in Bosnia from around the world. The Moeraki Boulders of New Zealand are an example of “cannonball concretions”. These famous, very spherical boulders are found on a beach in Otago. They are part of a Paleocene-aged rock formation, so they date back 60 million years and likely took millions of years to grow to their most massive sizes of up to 7 feet wide. Other examples of almost impossibly round cannonball concretions occur in Theodore Roosevelt National Park in North Dakota, and these ones are also quite reddish and iron-stained due to their mineral composition.
    *The Forbes link has a lot of popups.

    OK, so it's not a meteorite. Maybe it's an ammonite ?

    Maybe an erratic that rolled along time ago--rounded by water action?

    Semir Osmanagić, known as the 'Bosnian Indiana Jones', is a well-known pseudoarchaeologist who previously found the Bosnian Pyramids (that turned out to be natural formations). Same with these balls.

    The article mentions the sedimentary nature of the sphere, and one see areas where a couple of the thin layers have fallen away. Concretion is a very reasonable seeming explanation, especially since these sorts of spheres found throughout the world. If the sphere were carved from a uniform piece of stone, these layers should not be apparent.

    In this case his proof is in his pudding. The balls are pretty real, and interesting in their own right.

    But they are natural, not artificial.

    Is this in answer to my post? If so:

    1] It's not yet certain they are natural, though is the most plausible explanation.
    2] They're still interesting, each if he's a bit of a sensationalist.

    Bit of a sensationalist? Read the theories he promotes. His belief that they are not natural is a good argument that they are. If he told me the Earth was a sphere I'd probably start constructing a home made rocket to fire myself into the stratosphere to check.
