causality 

Noun (physics terminology): the natural sequential relation between any cause and its subsequent effect in the known universe, in which any effect is invariably preceded by the cause of that effect, and never the reverse.

"Newton's Third Law of Motion is essentially a confirmation of the principle of causality."

Causality 

A legend in Counter-Strike: Source, known for beating the odds while in a 12 on 12 tournament. He was the last one left against 11 enemies, and he ended up finishing them all off by himself with a Glock Pistol.

Causality is a god in Counter-Strike: Source, and if you see him, RUN!

temporal causality poop

The act of pooping so hard that you become immediately hungry and then the proceeding feast only leads to yet another poop. A vicious cycle. Particularly when you can no longer remember if the loop was started by a poop or a meal, at this point you know you have entered a temporal causality poop.

Dude I found the best 24-hour all-you-can-eat Buffet in Vegas with really nice toilets inside. I totally forced myself into a temporal causality poop. I was there for days!

Birth Control Causality  

A woman who is physically "inflated" from the usage of birth control. Unfortunately all of the negative symptoms (weight gain, larger breasts, blood clots, etc) have affected her, unlike some women who may not experience some or all the symptoms. The woman will appear chubbier or fatter than ever with a round or apple-shaped figure, her breasts are plump but sagging from tenderness, and she has a muffin top; however, on the bright side, her skin is radiantly clear.

A birth control causality can also be a woman who smoked and took birth control or did not take her birth control properly and ended up pregnant.

Poor things.

Eva was mad after taking birth control for two years. She is shaped like a pear, her love handles seem to flop over her pants, her arms are flabby and her boobs seem to scrape the floor. However, her acne has disappeared. Poor girl is a Birth Control Causality . Oh well, once again at least her skin's cleared up.

synchronicit causality 

The phenomenon where in people that are geographically separated experience a coincidence with no other possible explanation, that would not have happened otherwise.

You pick up the phone to dial your sister, and she is already on the line without dialing, or the phone ringing, as she has already called you.

But you know that if you did not go to call her, she would not have tried to call you - synchronicit causality

It was the act of picking up the phone that precipitated the event.

Preserved Causality Hypothesis

A hypothesis in theoretical physics and FTL research that states that even with faster‑than‑light travel or communication, causality would not be violated because some underlying mechanism would prevent messages from being received before they are sent. This could be due to the topology of spacetime (e.g., wormholes that are time‑like but still globally causal), limits on the kinds of trajectories that can be realized, or quantum effects that enforce temporal ordering. The hypothesis is essential for making FTL concepts physically plausible, as the standard argument against FTL is that it would allow backward time travel and paradoxes. If causality is preserved in all FTL scenarios, then such paradoxes would be impossible.

Example: “She defended the preserved causality hypothesis by showing that any FTL signal would still obey a modified light cone—it could outrun light but not its own past, preserving cause before effect.”

Preserved Causality Theory

A hypothetical framework proposing that faster-than-light (FTL) travel does not necessarily imply time travel or causality violation. Contrary to conventional physics (where FTL equals time travel via relativity), Preserved Causality Theory suggests that causality is more fundamental than light speed limits—that there's a deeper structure ensuring causes precede effects regardless of velocity. This could involve privileged reference frames, quantum non-locality extended to macroscopic scales, or novel spacetime geometry that allows FTL without temporal paradoxes. The theory opens the door to interstellar travel while keeping grandma safe from accidental erasure. It's the dream of every sci-fi fan who wants warp drive without the headache of meeting your own grandfather.

"But Einstein said FTL equals time travel!" they protested. "Preserved Causality Theory," the warp drive engineer replied, "suggests Einstein was right about light but wrong about causality being tied to it. We're going to Alpha Centauri in a week, and we'll be back before we left—no, wait, we'll be back after we left. Causality preserved. Probably." The theory remains unproven, but so does faster-than-light travel itself."
