I was wondering if anyone ever thought about using technology to stop the expansion of space, or at least a section of space. Much like how sections of space-time are warped by large physical objects, perhaps large sections of space-time can be warped to stop expanding (by somehow manipulating the dark energy that may be causing the expansion in the first place?) Any ideas? This is also assuming that it is dark energy that is causing the expansion. I also don't think we fully understand space/time or the universe in it's entirety yet.
