Faster-than-light travel

Faster-than-light travel refers to travelling at faster than light speeds or superluminal velocities. In the 33rd century, FTL travel is essential throughout the multiverse to conduct trade, diplomacy and war beyond the confines of a single planetary body. Three primary methods of FTL travel are currently practiced: warp-based travel; where realspace is warped around the vessel, jump-based travel; where the spacecraft makes a inter-dimensional jump through realspace and dimensional-based travel where the vessel bypasses realspace using an alternate dimension where the confines of realspace do not affect travel.

Methods

Dimensional-based

Dimensional based travel is the most complex and advanced method of faster than light travel in the 33rd century but has become standard with the dominant powers in the Multiverse, most prominently, the Terran Concordium. In the Standard Universe, the primary dimension used for this method of superluminal travel is riftspace, a subspace dimension that encompasses all of realspace. Riftspace is often known as simply "the rift" colloquially in the Concordium, being named so after the method of entry into the subspace dimension, through the use of dimensional rifts. Riftspace travel is one of the most efficient and fast methods of conducting faster than light travel. However this comes at the expense of being very energy intensive and also technologically complex to develop. Current riftspace drives require several magnitudes greater energy supply than warp drives and this is why typical ships using rift or dimension based travel utilise advanced energy generators such as antimatter reactors or dark energy generators to provide power.

Warp-based

Warp-based travel is the simplest but also one of the slowest methods of travelling faster than light. Warp travel is purely confined to realspace and instead of physically exceeding the speed of light, warp drives simply warp space-time around the vessel in a warp bubble. By doing so, the ship itself does not exceed the speed of light but to an outwards observer and thus travel-wise, does so, allowing FTL travel to be achieved without infringing on the laws of physics. Warp-based travel is often to first method of FTL travel discovered by a civilisation, and this was so with humanity, which did so in 2100.
