In ROTF we encounter Space Bridge technology with Jetfire and the Fallen. They function like point to point teleportation much like RDM Battlestar Galactica FTL. This ancient Decepticon technology. The later generation Decepticons do not have it. The Autobots on the other hand through Sentinel Prime developed a relay based Space Bridge technology for mass transport. This is the same Sentinel Prime whom Sam quoted with his Allspark rant that Einstein is wrong.
