I would be very interested to see a list of phenomena. Here is a list of what qualifies:
- It must be an event/effect that can be reproduced in a laboratory OR
- It must be an event/effect that can be observed by anyone possessing necessary equipment. Equipment that is fully defined and reproducable.
- The effect/event must have no strong scientific theory explaining it. Guesswork and theories with no evidence are allowable. In fact the effect/event could even blatantly contradict some known physical mechanism.
Here's one example; in the earliest days of powered flight, some stated that the bumble bee should not be able to fly. Of course since then science has worked out how this little insect manages it. But for a time, it was a phenomena.
