What could be the science behind cracking knuckles? Is it safe ? There’s a saying that it can cause arthritis later in life

On regular period of intervals, gas bubbles forms in the synovial fluid of the joints. Popping sound comes from busting of these bubbles in the joints.
And arthritis is something that occurs due to overload, overuse. It depends on the age, injuries etc. Their is no any scientific link between the knuckles and arthritis.
Yeah, some sort of soft tissue injuries and swelling can occur while knuckling.
