In this reality that greatly diverges from our own reality, an alien race of religious scientists have began an alien version of the Rapture.
Examples of technology
Alcubierre warp drive
The Alcubierre warp drive was discovered fifty-thousand years prior to the birth of Christ. It was necessary for the aliens because prior to the existence of the Alcubierre warp drive, they were using a class of rockets that used antimatter as their power sources. By using the Alcubierre warp drive, their spacecrafts can achieve faster-than-light travel by artificially producing a configurable energy-density field lower than that of vacuum (that's known to us negative mass) to be artificially created. Rather than exceeding the speed of light within a local reference frame, the alien spacecrafts instead traverse distances by contracting space in front of it and expanding space behind it, resulting in a true effective faster-than-light travel. Because objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre warp drive shifts space around an object so that the object would arrive at its destination faster than light itself would in normal space.
Isolating and storing antimatter is used as a fuel source for interstellar travel as part of their Alcubierre warp drive-type spacecrafts. Since the energy density of antimatter is higher than that of conventional fuels, an antimatter-fueled spacecraft especially an Alcubierre warp drive-type spacecraft would have a higher thrust-to-weight ratio than a conventional spacecraft.
Casimir–Polder force generators
The Casimir vacuum between parallel plates is used to fulfill the negative-energy requirement for their Alcubierre warp drives.
