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.
This has a chain reaction to your joints. As your muscles pull and strain, it causes more pressure and restriction on your joints, and in this case the elbow joint. Nitrogen gas, which is present in our body, becomes suspended in the synovial fluid that keeps our elbow joint lubricated and moving freely. Overtime, the pressure builds up so much that it has to pop in order to relieve the pressure â this is when you hear the popping noise from your elbow.
