Assume we reach a time in the future when Earth loses its gravitational pull on all matter on its surface and not tied down. Forget for a moment that life would have been extinguished in phases much before the end game of what is my question.
There will come a time when Earth with its weak gravity will not be able to hold on to it large bodies of water. When the water finally escapes into space, will it move as one big body of water or just a vast cloud of gas. Is there any such thing in space now which could be identified as having its origins bound within a land mass.
