[MCU] Why didn't other Titans leave their homeworld or try to conquer other planets?

Why did the Titans stay on Titan if they knew they were on the brink of disaster? Thanos has become the scourge of the entire galaxy by himself, surely an army of Titans could have easily taken another survivable planet for themselves.

I thought that was part of their downfall, they never expanded into the universe, became stagnant and ultimately ran out of resources. 

It was a pradise for a while but not one that could be sustained.
