Spacetime Bubble

A generic term for a localized region of spacetime that is topologically or causally distinct from its exterior—often used interchangeably with “warp bubble” in FTL theory. A spacetime bubble can be formed by extreme gravitational fields, exotic matter, or advanced metric engineering. Inside the bubble, the usual relationships between space and time may be altered: distances can be shortened, time can run at different rates, or the bubble can move independently of the surrounding universe. The concept is central to most theoretical FTL drive proposals, as well as to speculative “pocket universe” or “domain wall” physics.

Example: “The anomaly was a natural spacetime bubble, a remnant of the early universe where for millennia, only a few seconds had passed.”

Spacetime FTL Communication

A broader term for any FTL communication method that manipulates spacetime itself—whether through warp bubbles, wormholes, or metric engineering—rather than using exotic quantum effects or extra dimensions. It presupposes the ability to create and control localized distortions of the metric, enabling signals to take shortcuts through spacetime. It faces the same theoretical challenges as warp drives, including potential causality violations, but proponents argue that a preserved causality hypothesis could resolve those paradoxes.

Example: “The network used spacetime FTL communication, bouncing signals off microscopic wormholes that flickered in and out of existence. Latency was measured not in seconds but in Planck times.”

Someone who claims to do feats, either physically impossible, or possible yet obviously faked.

"I just got a girlfriend."
"Don't be a spacecougher."

"Caught me."

Spaceslop

a type of youtube short that features "what if" questions simulated in space engines (such as universe sandbox) often to farm engagement and well, money

they are typically dubbed with text to speech and subtitles

for example: "what if earth was 10x bigger" or "what if we replaced the sun with the nearest star"

my feed is filled with spaceslop

Space-Hop Era

The early period of human spaceflight characterized by chemical rockets that lack the power for continuous propulsion or independent navigation, forcing craft to "hop" from one planetary gravitational pull to another rather than cruising freely through space.

“We can't just take a detour to that Planet because we don’t have the fuel; we are still stuck in the Space-Hop Era.”

movie space 

A parking space very close to your destination, like whenever you see someone park in a movie, its always close.

im snaggin that movie space

when you are so involved in text messaging you block out everything around you.

Dude! watch out for that car!

Sorry I was in texter space
