subluminal

Ah, but on a subluminal voyage there was always time.

That culture was based on a bedrock of subluminal assumptions.

First, this vessel is able to travel only at subluminal velocities.

Consider how societies diverged when only subluminal transit was available.

"Just dropped out of warp; subluminal now and decelerating fast."

Seeking a more benign home, the trisolarians plan a subluminal invasion of the Earth.

That time would be on both ends of the trip, moving at subluminal speeds before and after the Bender did its magic.

Therefore, it cannot slow down to subluminal speeds.

The ship's speed had to be subluminal.

It is more likely that they were gravo-magnetically powered, like our own eggs and subluminal spaceships.

While traveling through a wormhole, subluminal (slower-than-light) speeds are used.

So we sent subluminal signals and inorganic probes.

These problems do not arise if the bubble velocity is kept subluminal, but exotic matter is still necessary for the drive to work.

In a subluminal empire, sixty light-years in diameter, new standards diffused slowly.

It was still the Subluminal period, signals crawling across the Sagittarius Arm at light speed.

"Two vessels going subluminal, ten light-seconds out."

Being constrained to the spacelike portion of the energy-momentum graph, it could not slow down to subluminal speeds.

The time the photon's energy spends as subluminal electron-positron pairs lowers the observed speed of light in a vacuum.

If wormholes are possible, then ordinary subluminal methods of communication could be sent through them to achieve superluminal transmission speeds.

The whine of the engines and the vibration in the deck plates signaled Enterprise's quick transition from subluminal velocity to high warp speed.

As the quantum eraser experiments rely on a classical, subluminal channel for coincidence detection, it is unclear whether superluminal communication would be possible by this method.

Radigast now had the Morholt darting closer at the highest subluminal velocity her captain would allow, accepting some element of danger from microcollisions in normal space.

We fly out beyond the Moon under subluminal power, just as though the starship were a gigantic egg, and then jump into the gray limbo for the first time.

The novels are set on the planet Dextra of the Delta Pavonis system, where the first human settlers arrive after a subluminal flight from a post-holocaust Earth.

It is also possible on a geostatic view for objects such as comets to vary their speed from subluminal to superluminal and vice versa simply because the distance from the Earth varies.
