What, you can't handle a few thargoids in null-space? :-)
If you survive for long enough your hyperdrive repairs itself, but you generally have to kill a few thargoids first.
It helps to have a retro-thruster fitted: use your rear-laser for as long as you can (until they get too close), then turn around, retro - hey presto, they're back on the edge of your scanner. :-P
