For an idea we are all familiar with, randomness is surprisingly hard to formally define. We think of a random process as something that evolves over time but in a way we can't predict.
Can random numbers be predicted?
Yes, it is possible to predict what number a random number generator will produce next. I've seen this called cracking, breaking, or attacking the RNG. Searching for any of those terms along with "random number generator" should turn up a lot of results.Can randomness be proven?
(True) Random Number generatorSuch a form of randomness cannot exist in a world governed by determinism under the laws of physics. Determinism can imitate randomness. But quantum physics has proven its effectiveness where the great principles of today have failed.
