    Technically everything moves at c (the speed of light) through spacetime, all the time. Most objects that have mass spend the majority of their motion in the time part, and thus move relatively slowly in space. If an object moves fast in space (where fast is a significant fraction of c) then it moves noticeably slower in time because the total spacetime vector value is always c.

    Photons, being massless, do not move through time at all, and move through space at c.






  • Hmm, every computing system is a collection of bottlenecks… in most desktops the CPU has a dedicated bus for the RAM because any other device in that path would slow down the communication with the RAM.

    The point is, bottlenecks can be designed around. Making the memory component faster makes it worthwhile to double or triple the memory bus bandwidth, or just reduce the amount of memory in the system while keeping the same level of functionality. And the slower components can be segregated out to their own communication paths (that’s what all the different pins on the bottom of the CPU are for).

    Usually the hardest part is getting the software to use the hardware properly. We’ve had consumer multicore processors for 2 decades now but most applications still don’t do parallel processing efficiently. Hell, a lot of them are still 32 bit and can’t use the 64 bit memory address space.

    tl;dr: hardware guys are genius wizards, software developers mostly suck
