The cosmic whale

What if the universe is an ocean and the planets and stars are just plancton? The stars are bioluminescent algae shifting around the immensity of endless dark matter waters. We, the earthlings, are nothing but molecules of a unicellular protist. Maybe membrane proteins. Our world may be complex for us and our lifetime seems to be a thing, but, if you zoom out, you see a huge mouth open ready to swallow it all. It's a cosmic whale, putting to an end the ephemeral life of the cosmic plancton. The end doesn't come to Earth only, but to a hole collection of gallaxies.
