When bored, as I often am, I imagine a possibility in deep space.
Today I imagined a slow collision between a bubble of blue oxygen unimaginably large encountering a red cloud of hydrogen. The mixing naturally creates water but I further wondered if other forces such as novas or black holes could give a vector force to the 'Space Tsunami'. So I googled space tsunami. https://www.nasa.gov/feature/supermassive-black-holes-may-generate-tsunamis-in-escaping-gas
Cosmic floods in exo solar systems may be creating life or death on planets beyond our sight.
It seems like anything you can think of, has been thought of except...
