I have a feeling we are not talking about the same "flaw".
For starters, I grant the premise that the universe could be closed, and could contract again. That's not my beef.
The flaw I'm talking about is the idea of being able to stay "outside" the Big Crunch to the new Big Bang..
In the same way "our" Big Bang was not an expansion in space, but an expansion of space - so it is that the Big Crunch will not be a contraction in space, it will be a contraction of space.
As they tried to keep themselves distant from the Big Crunch, they would find it impossible to do - because the universe would actually be shrinking toward a point. There would be nowhere to go. The whole universe would shrink down past 1 light year, past 1 AU, past 1 km and on down. Even if he ship could survive the radiation and gravity, eventually the universe would shrink till it's smaller than the ship! There is no "outside" a Big Bang.
