The Alcubierre Warp Drive

The Alcubierre warp drive is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by Mexican theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve apparent faster-than-light travel if a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.

Rather than exceeding the speed of light within a local reference frame, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel. Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination faster than light would in normal space without breaking any physical laws.

The Froning- Alcubierre Photon Drive

In 1980 Dr David Froning conceived a radical form of propulsion and a departure from the norm. He called it the Quantum Ram Jet but did not have any ideas about how to build it then, but realised that coupling matter with zero-point energy could be used to power a spaceship. The 

In 1985 he proposed the use of vacuum energy to power his Quantum Ram Jet.

The most important component of the Froning Photon drive is the Photon Force Field which is an axle Photon force field. How does it work and what does it do? 
It serves both as a shield and a screen and is vital for the following purposes:

For eliminating atmospheric friction.
For protecting from radiation and debris.
For neutralising mass.
For screening away unintended time travel.
For screening away other relativistic effects.
For generating an acceleration-assisting effect.
For extracting energy from the craft's motion through the quantum vacuum.

Strictly speaking, this is not a 'Warp' drive because it does not warp space but simply isolates itself from space-time effects.

Worm Holes

One of the most popular theories for achieving FTL travel is through the use of wormholes. These hypothetical tunnels in spacetime could create shortcuts between distant points in the universe, allowing spacecraft to traverse vast distances in a fraction of the time it would take using conventional methods.

Tachyons

Tachyons are hypothetical particles that travel faster than light. While these exotic particles remain largely theoretical, some scientists believe that harnessing the properties of tachyons could unlock the key to achieving FTL travel. Exploring the mysterious realm of tachyons opens up a realm of possibilities for future space exploration.
