Somewhere in the universe there are two planets. They both have life. They have huge vast oceans. And on their orbit, on some point they are getting so close that they share the same ocean.
so close, their atmosphere mix with each other, tides are getting high
to sky, and then getting connected in the space between them. Their
gravity holds everything in balance - it is a perfect balance like the
position of the earth. Tides meeting in the space, oceans getting
connected with each other and creatures swim through for coupling.
the night, all of them are glowing. In the middle of the ocean when you
look above you see the celestials. On some point, the ocean shared
between two planets getting thin and when you look down you see planets
and stars through the water. Days pass planets reach to a point that
their sun "rises". They are on a trinity system with three stars. Two
planets, connected with their oceans and three suns shinning over the
wild waters. Days pass and they are getting split.
Gravitational attraction pulls the oceans back. Creatures back to their homes until the next tide...
