Relative speeds also cannot exceed the speed of light. Since there’s no absolute reference frame, if this were possible it would be no different than exceeding the speed of light on “absolute” terms. Once you get up to speeds where this would matter, funny dilation effects that I’m too dumb to understand would prevent this.

For reading practice, I like using satori reader, the full service is paid but it has really nice grammar breakdowns and i like being able to click on words to see their definition/readings
