Researchers typically use random numbers supplied by a computer, but these are generated by mathematical formulas – and so by definition cannot be truly random. ... True randomness can be generated by exploiting the inherent uncertainty of the subatomic world.

Is absolute randomness possible?

Therefore, true randomness exists. As an aside, it turns out that the absolute randomness comes from the fact that every result of every interaction is expressed in parallel universes (you can't predict two or more mutually exclusive, yet simultaneous results).

Can true randomness be achieved?

“Pure randomness” can only be achieved if a computer measures a phenomenon taking place outside of its system such as in natural occurrences, from which a computer can get a “true random number.” True randomness occurs in events happening outside computer systems.
