I Often Receive Questions About How Fluids React To Extremely Hard And Fast Impacts. Some People Wonder

I often receive questions about how fluids react to extremely hard and fast impacts. Some people wonder if there’s a regime where a fluid like water will react like a solid. In reality, nature works the opposite way. Striking a solid hard enough and fast enough makes it behave like a fluid. The video above shows a simulated impact of a 500-km asteroid in the Pacific Ocean. (Be sure to watch with captions on.) The impact rips 10 km off the crust of the Earth and sends a hypersonic shock wave of destruction around the entire Earth. There’s a strong resemblance in the asteroid impact to droplet impacts and splashes. Much of this has to do with the energy of impact. The asteroid’s kinetic (and, indeed, potential) energy prior to impact is enormous, and conservation of energy means that energy has to go somewhere. It’s that energy that vaporizes the oceans and fluidizes part of the Earth’s surface. That kinetic energy rips the orderly structure of solids apart and turns it effectively into a granular fluid.

Glass Barrier

My glass barrier hides my pain so that no one has to deal with it, and is almost impossible to break. Of course, it cracks and my emotions spill out some times, but only a few have completely shattered it and saw who I really am. Thank you to all who have done so, you have no idea how much I love you all

The Rabbit and the Moon

There once was a young rabbit who loved to gaze upon the stars. She told her mother that she wanted to visit the moon one day and gift her with a clump of its soil, so that her rings could always shine with the most beautiful golden light.

Before she could fulfill her promise, her mother had fallen ill and passed away. Her final wish to the young Eevee was that she look to the moon when loneliness looms and be reminded she’ll always be here, watching over her.

Young December wandered alone for many months, longing for her mother’s loving embrace that would never come again. When loneliness shrouded her world, she visited her favorite clearing and looked up. Up at the moon and the stars where she would find comfort in their light.

Upon a shooting star dashing across the sky, she made a wish. A simple wish to go to the moon like she always wanted so she could be with her mom again. Believing it was wishful thinking something like that could happen, she retreated for the night.
