Either way, is this like "bending" space and time or something?

Space-time is pretty much the name given to the fabric of space and time as they are interlinked...

Think of it as a grid... just found this image, good representation:

Gravity creates a dip/well in the grid, imagine a ball rolling around the grid... if it gets to a point in the well where it is just going to roll around the dip that the earth creates, it will stay in orbit around the earth.

(I'm giving this background to help explain)

Another example is that a black hole is a well which goes vertical, so 'nothing' can escape.

Anyway... what these guys seem to be suggesting is keeping the space craft's travel accross the grid at the same speed, but expand the grid squares behind the ship & shrink the grid squares in front of the ship.... which should also push the ship along.

As for the first comment... he didn't seem to realise that they were talking about dark energy, not dark matter - the two things, while similarly named are very different things.
