I'd like to learn about events that are known to be 'uncaused'.
I expect that the claim is false, or at least not known to be true.
Please read very carefully what I wrote.
I did not say that it is known that many events are uncaused.
I said, it is not known that many events are caused.
If an event is apparently random, and a cause for it is unknown, then we do not know that it is uncaused, but we also do not know that it is caused.
I would argue that it is impossible to rule out a hidden cause via evidential means. The only way to rule out causes would be some theoretical argument.
At the quantum level (where the vast majority of events are taking place) most events are, as far as we can detect, random in nature and thus not known to be caused, or are apparently partially caused. Any claims that causation is universal are not founded on evidence.
When an electron emits a photon of light, energy is conserved. We might say it was 'caused' to emit the photon because it had more energy than it 'likes' to have. But the timing of the emission is only probabilistic, and direction of the emission is apparently entirely random. So if you ask what caused that electron to emit that photon at that time in that direction the answer is we don't know, probably can never know, and do not know that there was a cause.
