Penetration Funnels - impacts on viscous targets

In the 1930's, researchers proposed that the characteristics of the Carolina Bays could be best explained by impacts, but the failure to find any trace of the projectiles that made the bays eventually led to the idea that the bays were made by the action of waves driven by prevailing winds blowing on pools of water. More recently, the Carolina Bays have been said to be the remnants of ancient thermokarst lakes.

The density of the projectile determines the characteristics of the penetration funnels. See these short videos:

Craters a half-mile across, and quakes equivalent of magnitude 7.8 - I need to stop complaining that I've had a 'rough' day.

Hello Antonio,
There is one detail in your impact animation that I would suggest be changed. In addition to the impact angle, theta, there is the interior angle of the cone, let’s call it theta. The missile travels down the central axis of the cone with the cone expanding in all directions as the shock wave moves through the ground, like the wake formed from a ship. Seen in vertical cross section, for a an oblique impact, the missile is traveling done the central axis and the shock wave expands down and backwards in addition to forward and up. The missile would not move along the lower surface of the cone and displace essentially all the material up and forward. This detail doesn’t change any conclusions about the Carolina Bays, it’s just a small quibble about this animation.

Hi Antonio. Are your explanations experiencing success in academia? Is the old guard a severe restriction to such a "new" idea? I wish you all the best in your pursuit of this paradigm shift.
