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.
However, if youâre not in the habit of cracking your joints and you still hear an unusual popping sound, it might not be due to your joints cracking at all. Such noises may also come from your tendons, which keep your muscles attached to your bones, and ligaments, which connect your bones.
