Between biological science and psychiatry, modern medical science solves many past Human mysteries. Conditions that once made circus sideshows popular are easily explainable. Today we know that conjoined twins, once called "Siamese twins", result from the incomplete separation of identical twins during pregnancy. Both the tallest and the shortest people on earth may still appear in the Guinness Book of Records, but neither are any longer candidates for Ripley's Believe It or Not.
The results of modern research into some human mysteries, such as mysterious human remains, still amaze us and some human mysteries continue to intrigue us.
- Spontaneous human combustion (SHC)—Do people suddenly burst into flame? Could it happen to you?
- Spontaneous human invisibility—Now you see me, now you don't. Is it real or is it a trick of the memory?
- Reverse speech—Is there hidden meaning in what we say, if we say it backwards?
- Speaking in tongues (glossolalia)—Is it biblical or is it gibberish?
- Dermography—Is it a hoax or is it a form of paranormal communication?
- Aura Photography (sometimes referred to as Kirlian Photography)—Do we each have a visible aura or is it just a camera trick?
- Bilocation—Can you really be in two places at once?
- Levitation—Can people lift themselves into the air without pysical support?
- Doppelgangers—Do you have a ghostly counterpart?
- Mysterious Remains—Where did they come from and what do they mean?
- Out-of-Body Experience (e.g. Astral Travel)—Can you really leave your body and visit other places?
- Near-death experiences—What can these tell us about life and death?
- Parapsychology (psychics, ESP, etc)—Are they for real?
Stigmata, legends of shapeshifters, and singular anomalies such as the Green Children of Woolpit remain in the shadows of human understanding; subjects, not yet fully explained that wait for exploration and research to bring them out of the mysterious world of the paranormal.
