Pseudorandom sequences typically exhibit statistical randomness while being generated by an entirely deterministic causal process. Such a process is easier to produce than a genuinely random one, and has the benefit that it can be used again and again to produce exactly the same numbers - useful for testing and fixing software.
Another similar explanation suggests that when you âcrackâ your knuckles, or any other joint, it expands the space between your bones, creating negative pressure that draws synovial fluid into the new gap. This influx of synovial fluid is what causes the popping sound and feeling when you crack a knuckle.
What causes neck cracking and popping? The snapping or grinding of your neck may be caused by: Synovial fluid changes. The synovial fluid between your joints lubricates movement, and when the pressure changes in this fluid, it creates gaseous bubbles. According to a 2015 study, the creation of these bubbles makes a cracking or popping sound.
