Nigel asked the Naked Scientists:
   Dear Sirs. 1) Given that a jet pilot experiences G-forces when making a right-turn in a light medium (air), does a fish experience G-forces when making a right-turn in a heavy medium (water)? 2) Similarly, if the space between objects in the ether is filled with a quantum fluid, could a spacecraft (if it can shift its mass-time to a density level equating the fluid density in the ether) thereby enable it to manoeuvre free of G-force constraints?
What do you think?

Yes. There's not a great deal of difference. As a fish makes a turn in the water its internal organs want to go straight. The G-forces being felt are its body forcing the organs turn with the body.
