The discussion centers on the behavior of a bubble of water in zero gravity and its implications for fish within it. Surface tension is confirmed as the reason the water would hold together when the shell is removed. The conversation also explores the potential for fish to suffocate if they swim outside the bubble and raises the intriguing question of whether air-breathing marine animals, like dolphins, could adapt to swim through air in a zero-gravity environment.
PREREQUISITESAerospace engineers, marine biologists, physicists, and anyone interested in the effects of microgravity on fluid behavior and aquatic life.
Yes, because of surface tension. You can find videos of this.Alltimegreat1 said:What if you were in a spaceship in outer space and had a sphere filled with water and some fish in it and then carefully removed the shell, leaving behind only a bubble of water. Would the water hold together..
This could happen. An interesting question would be, if it can swim back to the water through the air. Or if a dolphin, which can breathe air, would learn to swim through air in zero-g.Alltimegreat1 said:...and would could the fish would swim outside the bubble and suffocate?
