Here is a list of 10 Crazy Theories that People Used to Believe.
1. The Vulcan Planet
For a while astronomers saw that Mercury’s orbit was not perfect as classical mechanics predicted, and they suggested that there was a planet between Mercury and the sun. It was named Vulcan. This was actually a pretty reasonable idea at that time because Neptune was similarly mathematically predicted before it was directly observed, based on the orbit of Uranus. Further, it was really, really hard to search for Vulcan because due to its proximity to sun it could easily evade detection. When Einstein came out with the theory of relativity, it perfectly explained the differences you observe in Mercury’s orbit. Vulcan is a great example of how science works. You do the best you can with the information you have, trying to figure out a solution, until someone finds a better idea to match the data. – Source
2. Cleanliness
Doctors believed that a gentleman’s hands are always clean. So doctors treated patients one after another and sometimes even cadavers without washing their hands. Mortality was high. In fact, Ignaz Semmelweis, the doctor who first proposed that medical professionals should wash their hands before handling patients was so mocked by his peers that he suffered from a nervous breakdown. He was committed to a mental institution and died in there of septicaemia only 14 days later, possibly as the result of being severely beaten by guards. – Source
3. Phrenology
Phrenology is the study of the structure of the skull to determine a person’s character and mental capacity. This pseudoscience is based on the false assumption that mental faculties are located in brain “organs” on the surface of the brain and can be detected by visible inspection of the skull. The Viennese physician Franz-Joseph Gall (1758-1828) claimed there are some 26 “organs” on the surface of the brain which affect the contour of the skull, including a “murder organ” present in murderers. – Source
4. Phlogiston
Phlogiston was a hypothetical substance formerly thought to be a volatile constituent of all combustible substances, released as flame in combustion. It was first stated in 1667 by Johann Joachim Becher. The theory was an attempt to explain processes such as combustion and the rusting of metals, which are now understood as oxidation. – Source
5. Radiation Good for Health
When researchers first started studying radiation more than a century ago, they believed that radiation was good for health. In fact, markets were selling radium pendants for rheumatism, all-natural radon water for vigor, uranium blankets for arthritis, thorium-laced medicine for digestion and radioactive water for good health. Even Marie Curie refused to believe that radiation was harmful. – Source
6. Alchemy
Isaac Newton was a huge believer in alchemy, the now discredited science of transmuting base metals into more noble metals (eg. lead to gold). He apparently spent a lot of time on the subject. Alchemy though possible with today’s technology, is really not practical. Large Hadron Collider can smash atoms together and create gold particles. Only problem is that the amount it creates is tiny and it costs way more than what gold is worth. – Source
7. Homunculus
Preformationism was a theory of heredity that claimed that either the sperm contains complete preformed individuals called “animalcules.” Development was therefore a matter of enlarging this into a fully formed being. The term homunculus was later used in the discussion of conception and birth. It was later pointed out that if the sperm was a homunculus, identical in all but size to an adult, then the homunculus may have sperm of its own. This led to a reductio ad absurdum with a chain of homunculi “all the way down.” This was not necessarily considered by spermists a fatal objection however, as it neatly explained how it was that “in Adam” all had sinned: the whole of humanity was already contained in his loins. – Source
8. Wandering Uterus
The belief in the “wandering womb” was part of the teachings of Hippocrates. A description of the theory of a “wandering womb” is from Aretaeus, a physician from Cappadocia, who was a contemporary of Galen in the 2nd century. He wrote that the uterus could move out of place, and float within the body. He said that uterus wandered around the body causing faintness, nervousness, sexual desire, insomnia, fluid retention, heaviness in the abdomen, muscle spasm, shortness of breath, irritability, loss of appetite for food or sex, and a tendency to cause trouble. – Source
9. Bloodletting
Phlebotomy, or bloodletting, is the longest-running tradition in medicine. It originated in the ancient civilizations of Egypt and Greece, persisted through the Medieval, Renaissance, and Enlightenment periods, flourished in Arabic and Indian medicine, and lasted through the second Industrial Revolution. Doctors bled patients for every ailment imaginable to remove ‘dirty blood.’ In fact, George Washington was a big believer in bloodletting and this treatment may have killed him when he had 3.75 liters of blood drawn in 9-10 hours. Often times it was prescribed by physicians, but performed by barbers, and this led to the division of the physician and surgeon. The stripes on barbershop poles are homage to the practice of bloodletting. Barber poles were originally used to indicate that the barbers provided small surgeries such as bloodletting and tooth extractions in addition to cutting hair and trimming beards – Source
10. Mercury as Medicine
Mercury was used as a disinfectant, a cure for syphilis, and a pill for immortality. MercuryI chloride has been used as a diuretic, topical disinfectant, and laxative. Mercury chloride was once used to treat syphilis. It was so toxic that sometimes the symptoms of its toxicity were confused with those of the syphilis it was believed to treat. – Source
You forgot religions.
Remind me when religion was proved wrong? Last I checked the big bang theory has more holes in it than most religions.
Your mom has more holes and we call her the big bang around here. Love you illegitimate son. Keep praying ill come back one day
“”Remind me when religion was proved wrong? Last I checked the big bang theory has more holes in it than most religions.””
I laughed so hard when I read this.
So many different religions with so many different prophets and so many different Gods. But Christianity must have it right why? Because a book says so. But ya know what? Everyone else from every other religion says that THEIR book is the one that’s correct.
ROFL!!
(Extra credit to “your mom’s milkman” too!)
Interesting facts. I believe in a creator God who created all things perfectly including His relationship with man. That relationship was broken when man disobeyed. Jesus came and restored that relationship. I’m not going to venture into apologetics or get into a battle of words with anyone. I have as much right to state my position on the web as anyone else. However, I will not attack a person and try to belittle them for their beliefs. It says a lot about a person who will hide behind a computer and tear others down in an attempt to build themselves up.
If you believe in a god, then you’re just f**king retarded and backwards. You’re thinking is retrograde.
Also, I don’t hide.
You know what, I take it all back now. Tony baloney and The Milkman are the real MVPs.
All heil Tony Baloney. Blessed be thy name, for he is Our Creator.
For He died for your made up sins when someone in a fictional book made up some sh*t. Let us pray that The Milkman will deliver us from your stupidity. Amen.
Hello, also i think that you You forgot religions why?
Guys calm down, okay
This is worse than tickld 🙂
Let’s just be friends
The Bible: Proof God exists
Spiderman comics: Proof Spiderman exists.
Religion is a crutch for weak people
Number five: radiation has been proven to be good for you in small doses. The Rocky mountains contain a lot of uranium and guess what? There’s not nearly as many cancer cases there. It’s called hormesis
Darwin: Proof evolution exists?
The fact that any biologist, physicist, or any other scientist cannot give a ballpark guess on the probability of all or even any specific part of evolution means it’s definitely not proven.
Try it.
