It would certainly clear the atmosphere

With no gravity, flat Earth would no longer be able to hold onto an atmosphere. Without our protective blanket our skies would turn black, and surface life would cease to exist.

Water would boil away in the vacuum of space, and the surface temperature would plummet. But it isn’t all bad news. Deep oceandwelling organisms that don’t require oxygen – anaerobic bacteria – and those that don’t need sunlight to generate food and energy – chemosynthetic bacteria – might just survive. After all, such bacteria have endured long trips in space and lived to tell the tale.
