Faster-than-light travel, often abbreviated to FTL, is the method by which ships traverse the vast emptiness of space between star systems. Advancements in technology can grant improvements to the speed at which ships jump to FTL and even unlock experimental FTL drives.

A fleet will initiate FTL travel when its first ship reaches the edge of a system or bypass, regardless of the current position of other ships.

Hyperlanes

A hyperlane network predates all other known construction in the galaxy and connects the star systems together to allow interstellar travel, although some systems may be more isolated than others. Ships move at sublight speed until they reach a hyperlane entry point (shown as an arrow on the system map). The Hyperlane Density setting determines the number of hyperlanes individual systems can have. A double value creates a very unrestricted game where interdiction is next to impossible. Conversely, a half value connects the galaxy linearly, with most systems having only two hyperlanes, allowing for a highly defensive game.

FTL drive	Cost	能源（Power）	FTL charge time	Tactical jump	Required technology	Crisis date	Description
Hyper Drive I	5	10				regular	Ships equipped with Hyper Drives travel swiftly between the edges of star systems along interstellar hyperlanes.
Hyper Drive II	10	15	-25%		超空间航道突破点（Hyperlane Breach Points）	regular
Hyper Drive III	15	20	-50%		超空间滑流（Hyperspace Slipstreams）	regular
Jump Drive	20	30	-70%		Jump Drive	50 years earlier	The Jump Drive tears ship-sized holes in the very fabric of reality, allowing for near-instantaneous movement between systems. The nature of the space the ship passes through on this journey is still poorly understood.
Psi Jump Drive	20	30	-80%	+50% range	灵能跃迁引擎（Psi Jump Drives）	50 years earlier	The Psi Jump Drive harnesses the psionic potential of the ship's crew to warp the local space-time continuum, eliminating the distance between the point of origin and the destination. Supposedly.

Systems that are restricted because of closed borders are shown in red on the galaxy map. Home systems of Space Creatures that haven't been investigated with the initial special project are also restricted.

FTL Inhibitors

FTL Inhibitors are devices present inside Fortress buildings and at least Starport level starbases once the 超光速抑制 FTL Inhibition 超光速抑制（FTL Inhibition） technology is researched. Hostile fleets can only leave a system with an FTL inhibitor through the same hyperlane they entered from.

Tactical Jumps

Ships equipped with Jump Drives or Psi Jump Drives can execute Tactical Jumps. Tactical Jumps allow a ship or fleet to instantly travel to any system within a large range indicated by a yellow dotted circle. After jumping the fleet spends 200 days recharging, during which time it suffers -50%  亚光速航速（Sublight Speed） and Weapons Damage.

Experimental Subspace Navigation

The  试验性超空间导航（Speculative Hyperlane Breaching） technology enables science ships led by a scientist Leader to travel directly to a destination, ignoring the hyperlane network. During the transit the ship is considered MIA. Experimental Subspace Navigation can be used to bypass impassable areas such as a guarded system, a closed empire's borders or the galactic core.

Rolling subspace tides

The L-Cluster as well as the system housing the Corrupted Avatar guardian cannot be entered via either Experimental Subspace Navigation or Tactical Jumps and attempting to do so will show a notification about rolling subspace tides allowing only conventional travel. Both Experimental Subspace Navigation and Tactical Jumps can be used to leave the said systems however. The rolling subspace tide around the Corrupted Avatar system will recede once the system has been entered at least once via its wormhole.

Bypasses

Humanoid Empire using a wormhole

There are two types of Bypasses in Stellaris: wormholes and gateways. Both offer instantaneous travel but require research in order to be usable. The number of Bypasses can be adjusted at settings before the start of a game session. Ships will automatically use Bypasses if the route is shorter, shown on the starmap by a blue travel line.

Wormholes

Wormholes are natural formations that come in pairs and link two random systems across the galaxy. Initially, wormholes are too unstable to allow passage through them, but once an empire obtains the  虫洞稳定（Wormhole Stabilization） technology, that empire's science ships can stabilize wormholes for that empire by right clicking on the wormhole or its system, opening them permanently for their empire. This only allows passage through that wormhole for ships of that empire; other empires must research the tech themselves, and then also "stabilize" that wormhole, before being able to use it. Clicking on a wormhole will shift the camera to the connecting system. Like hyperlanes, a wormhole cannot be used if the other end lies within an empire with closed borders except if war is declared.

One of the wormholes will always lead to the Sealed System, a trinary system with no hyperlane connection containing a Gaia planet that is guarded by a Corrupted Psionic Avatar. This wormhole will be present in the galaxy even if wormholes have been disabled.

Wormhole generation events

The Alien Machine event can be triggered by investigating an anomaly with the same name that can appear on asteroids. One of the two event options will lead to the creation of a new wormhole pair, one end in a system 2-8 hyperlanes away and the other in a system 15-50 hyperlanes away.

If Earth is destroyed with a World Cracker there is a 50% chance of creating a wormhole in the system leading to another newly created wormhole.
