To me reality can be studied in a lab. Take for example quantum physics: Quantum scientists will tell you that if you claim to know anything about quantum physics you really know nothing about quantum, however it is still studied in a lab-proving its reality. Gravity and magnetism can be studied in a lab. All things we can't see but know exist. Not to say there aren't things we haven't discovered yet. But I certainly am not going to believe it until its discovered and studied.
