Space Fold

Space Fold Technology is a propulsion system that enables faster than light travel. The system folds the fabric of space-time (hence the name), thereby allowing a spacecraft to instantaneously travel via artificial micro-wormhole between two distant points in space.

The crew of the SDF-1, which was rebuilt by the United Earth Government, was forced to conduct a space fold to escape the attacking Zentraedi invaders during the initial battle of the First Robotech War. The fold was conducted 2000 feet above Macross Island and was intended transport the starship to the far side of the Moon. Such a low altitude space fold shocked Commander Breetai and was deemed impossible by Exedore, but was nevertheless accomplished by the Humans. (Macross Saga: Space Fold)

In 2010, millions of Zentradi ships folded all around Earth. When they were in position, they opened fire and nearly completely destroyed the Earth. (Macross Saga: Force of Arms)

Later, the end of the First Robotech War, the newly built SDF-3 used a fold system to depart Earth. After an Invid attack, the fold generators were destroyed. (Robotech II: The Sentinels: Departure)
Hyper-space foldThe Southern Cross fold out of the Second Robotech War's first battle. (Robotech: The Movie)

In the first battle of the Second Robotech War, the Southern Cross were losing and outnumbered. Their computer was jammed, and they could not leave their current position for over 15 minutes. Their only hope was to do a hyper-space fold. They were successful in activating the fold, which also wiped out a large number of the enemy. (Robotech: The Movie)
Faster-than-light (also superluminal or FTL) communications and travel refer to the propagation of information or matter faster than the speed of light. Under the special theory of relativity, a particle (that has rest mass) with subluminal velocity needs infinite energy to accelerate to the speed of light, although special relativity does not forbid the existence of particles that travel faster than light at all times (tachyons).

On the other hand, what some physicists refer to as "apparent" or "effective" FTL[1][2][3][4] depends on the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations in less time than light could in normal or undistorted spacetime. Although according to current theories matter is still required to travel subluminally with respect to the locally distorted spacetime region, apparent FTL is not excluded by general relativity.

Examples of FTL proposals are the Alcubierre drive, and the traversable wormhole, although the physical plausibility of some of these solutions is uncertain.
