About this universe
Corallis dives where the light fades and colours turn into sound. From glowing corals to invisible currents, the ocean is a kingdom of questions held in suspension.
The whys of this universe
-
Why do waves always arrive parallel to the shore?
Because as a wave moves into shallow water it slows down. If it arrives at an angle, one end brakes before the other, the wave pivots and ends up facing the beach.
-
Why is the sea salty?
Because rain has been dissolving rock for billions of years: rivers carry the salt to the ocean, the Sun lifts the water back into the sky, and the salt is what stays behind.
-
Why are there tides?
Because the Moon pulls on the sea harder on one side of Earth than the other: the ocean stretches into two bulges that the planet rotates through each day.
