Why does relativity mean that mass changes with speed?

Why does relativity mean that mass changes with speed?

    Esther Inglis-Arkell Everyone knows that relativity plays hell with time, and that it can do a number on space, but what about mass? Why do objects get more or less mass depending on their relative speed? We’re going to give you a quick explanation of why running can make you gain weight. No, [...]

A Slower Speed of Light — MIT Game Lab

A Slower Speed of Light — MIT Game Lab

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. Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player’s own maximum walking speed. Visual effects of special relativity gradually [...]
