Educational/game applications of relativity simulations: Users frequently referenced and discussed interactive tools like MIT's "A Slower Speed of Light" game for visualizing relativistic effects.
"A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments... Visual effects of special relativity gradually become apparent to the player"

Debate over the "speed through time" slogan: A detailed technical discussion challenged the popular science notion that all objects move at c through spacetime, highlighting dimensional inconsistencies.
"Your own clock is one second per second, which is a pure number, 1... that's not a speed... You can't put meters per second on one side and a bare number on the other and call it a triangle."
– Kranar
Connections to sci-fi, perception, and real-world tech: Commenters linked the concept to works like Discworld and Three Body Problem, questioned human-scale perception of light speed, and noted implications for technology (e.g., fiber optics, drones).
"The first few Discworld books explore this a little bit too... Darkness travels even faster than light on Discworld, because it has to be fast enough to get out of the way when light arrives."
