Faster-than-light Updated +Created
One argument of why, is that if you could travel faster than light, then you could send a message to a point in Spacetime that is spacelike-separated from the present. But then since the target is spacelike separated, there exists a inertial frame of reference in which that event happens before the present, which would be hard to make sense of.
Even worse, it would be possible to travel back in time:

Ubuntu feature request Updated +Created
Sometimes it just feels like Ubuntu devs don't actually use Ubuntu as a desktop.
Some extremely annoying problems are introduced and just never get fixed, even though they feel so obvious!
Would never happen on Mac...
