lightbox 

An emergent theory of space-time in which the speed of the fastest phenomenon is limited by the aggregate amount of the material in the universe, material has no discrete point of origin, and space is infinitely large.

Stipulates that any "fastest" phenomenon in the universe ie. light must have a discrete origin point.

Argues that in contrast to approaching the speed of light requiring all the material in the universe, achieving infinite speed requires no mass at all and would cause linear time to stand completely still.

Posits that the universe moves infinitely fast outside of itself obviating the existence of other universes ie. outside of the universe it is eternally now.
Lightbox argues that there are two obverses but there is only one inverse.

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
You didn't get any napkins with your takeout pork fried rice? Womp womp.
