What if this event is the Great Filter? How common is an event of this magnitude in the universe? What if this is how Earth got its water and without something like this happening inner planets in the habitable zone cannot get retain water for complex life?
>>16803008then there wouldn’t be life on earth right now. we already know a planet crashed into the pacific ocean
>>16803008That's close, but I think it's more specific than water (which is more common on icy asteroids/comets than on rocky proto-planets). The moon is the cause of the tides, and without the moon the tides would only depend on the earth's position compared to the sun. It's possible that the tides created continuous zones which allowed aquatic life to become amphibious and then fully terrestrial, which is a prerequisite for metalworking and therefore a prerequisite for space travel.
>>16803689if you have plants in the water you are eventually gonna get plants on the land, if you have plants on the land you are eventually gonna get creatures eating those plants
>>16803008You have several moons that's projected to have oceans and one moon projected to be the the next earth (Titan) in 500 million to 2 billion years within this solar system alone.I don't think liquid water is the great filter.
>>16803232Reading comprehension. He's saying an event like this DID happen and the rarity of such an event is the filter.
>>16803008Every planet went through collisions with other protoplanets when they were a protoplanetIt's why Ouranos spins on its side and Venus rotates retrograde For it to be a filter it would have to be a rarer occurrence
>>16803712This is true, but tides make it much more likely for plants to be moved onto the shore and left there, and they also create selection pressure for water-dwellers that are capable of moving on land for short distances to not be stranded out of the water.
>>16804034>It's why Ouranos spins on its sideIf you knew what happened to Ouranus you would be spinning on your side too.
>>16803008Your "filter" is really a "sieve".Water is a neccessary condition for life to begin. Earth wasn't full of volcanic vent microplanktons thinking, "damn, i is thirsty!".The Watery Moon ball had to come here, dump her moist load, and toss her used rocks away to be our Moona today.That's a sieve. A must have before.A filter is a bunch of proto-apes releasing a bunch of custom cold viruses outside of an open air wet bushmeat market in the most densely populated section of the planet.
>>16804098Neptune was closer in the solar system in the past before it migranted Do you think neptune tapped that shit on his way out
