10 Crazy Paradoxes That Will Blow Your Mind

10 Crazy Paradoxes That Will Blow Your Mind

A paradox is a premise that contradicts itself. It’s a situation that seems to defy logic by producing an inconsistency that goes against common sense. Most logical paradoxes are known to be invalid arguments. However, they are still valuable for promoting critical thinking and sometimes proving a point by contradiction. Teasing your mind and question everything you think you know makes for great intellectual activity. Indeed, the closer you examine things, the more you’ll start to discover paradoxes all around you.

Here are some of the most fascinating paradoxes you should know about. These will boggle your mind every time you read or think about them. Enjoy!

1. Likely to exist means likely to be found, but where is everybody?

A mind-blowing paradox comes from the apparent contradiction that exists between the high probability of extraterrestrial civilizations being out there somewhere, and our lack of alien contact or evidence.

In a universe of infinite space, the odds of life existing on a planet other than Earth are pretty high. However, no confirmed signs of intelligence have been spotted outside Earth, either in our galaxy or in the more than 80 billion other galaxies of the observable universe.

Hence physicists Enrico Fermi’s famous question: “Where is everybody?”

2. Does an object that has all its components replaced remain the same object?

This is a classic paradox drawn from the ancient Greeks’ original Ship of Theseus Paradox. It was famously described by Plutarch to get at the contradictions of identity. It goes like this:

You have an old wooden ship. You remove a plank from the ship one at a time and replace it with a new plank. You do this with every piece until the old ship is completely replaced. Is it still the same ship? If you construct a new ship out of the old pieces you took off the first ship, which one is the original ship?

A newer version of this paradox that drives the contradictions of identity closer to home replaces the “ship” with the “brain”. If you somehow quickly replaced parts of your brain material with identical clones and made a separate brain with the old brain material, would that be you too? Would you still be you?

3. Time travel (if possible) would result in some extremely strange situations.

Consider the following version of the popular science fiction themed Bootstrap Paradox, involving time travel and bringing an object or information back in time:

A stranger appears out of nowhere and hands you a strange device. The stranger then runs away and you never see them again. You discover the device handed to you is a time machine. After holding it for a while, you get bored. Instead of getting rid of it, you figure: “Hey, why not give it to myself?” So you go back in time and give yourself the device hence starting the whole cycle again.

Where did the device come from?

4. Can you travel back in time and prevent yourself from being born?

Another famous example of a time travel paradox is the Grandfather Paradox. In this mind blowing scenario, someone travels back in time and kills their own grandfather to prevent their own birth.

Think about this: A girl goes back in time and kills her grandfather before he has a chance to meet her grandmother and sire her father. Since her grandfather is dead, the girl was never born.

If she were never born, how could she kill her grandfather?

5. Can an omnipotent being defy the laws of logic and be both omnipotent and not omnipotent?

This version of the Omnipotent Being Paradox arises from the simple but strange exclamation: “Let God Almighty create a stone, which he himself is not capable of lifting!”

Can God be omnipotent and not at the same time? How does free will even exist if God is omniscient?

These are just some of the many paradoxes that arise when you try to apply logic to definitions of God or an almighty being.

6. If destiny designed a master plan which defines everything that is to happen, isn’t it useless to go to a doctor, for example?

According to this Lazy-bones Paradox, if you are ill and it is your destiny to regain health, then you will regain your health whether you visit a doctor or not.

If it is your destiny not to regain health, then seeing a doctor can’t help you. This is a paradox that might arise if you reject the notion of an omnipotent God or a supreme being who’s in charge.

How would you question this premise or supposition?

7. A heterological word is a word that does not describe itself. Does “heterological” describe itself?

For example, “verb” is a heterological word since it is not a verb (as opposed to “noun,” which is itself a noun). Similarly, “long” is a heterological word since it is not a long word (as opposed to “short,” which is actually a short word). So then, is “heterological” a heterological word?

This is one of many self-referential paradoxes that have kept mathematicians and logicians up at night.

If “heterological” were a word that didn’t describe itself, then it would describe itself. However, if it did describe itself, then it would not be a word that described itself.

8. If someone says “I always lie,” are they telling the truth? Or are they lying?

The great stoical logician Chrysippos came up with a paradox popularly known as the Liar Paradox. It tells of a Cretan who sails to Greece. Upon arriving, he is greeted by Greek men on the shore and says, “All Cretans are liars.” Did he speak the truth, or did he lie? A week later, the Cretan sails to Greece again and says, “All Cretans are liars and all I say is the truth.”

The Greeks were truly puzzled. None were more confused than the grammarian and critic Philetus of Cos, who is said to have died of exhaustion while attempting to resolve the paradox.

Maybe we should just let this one go unsolved then? No?

9. A barber shaves everyone who does not shave himself, but no one else. Who shaves the barber?

This paradox is similar to the Liar Paradox. It was formulated by English logician, mathematician, and philosopher Bertrand Russell to emphasize the importance of establishing careful rules when creating sets. His Set Theoretic Paradox would lay the groundwork for 20th-century mathematics.

It goes like this: There is only one barber in town. The barber (who is a man) shaves only those men who do not shave themselves, but no one else.

Who shaves the barber? Does he shave himself?

10. What happens when an unstoppable object faces an immovable object?

An ancient story is told of a man who was walking through a market when he came across a merchant. The merchant advertised two of his wares boldly: “This spear can pierce any shield!” and “This shield can block any spear!”

The man contemplates these opposing statements for a moment. He then walks up to the merchant and asks, “What happens when you pierce the shield with the spear?” The merchant had no answer to this question.

A more recent account of an unstoppable object facing an immovable object involves a bullet and armor. Imagine there is a bullet which can shoot through any barrier. There is also some absolutely bullet-proof armor which no object can penetrate.

What will happen if such a bullet hits such an armor?

11 Hidden Benefits of Using Oil Diffusers

11 Hidden Benefits of Using Oil Diffusers

Affordable, relaxing, and healthy, oil diffusers are gaining popularity with people everywhere due to their extensive benefits. Oil diffusers work through the simple process of oil diffusion, which uses heat to turn oil into a vapor that is then spread around a living space. Diffused oil can have several relaxation and health-related benefits, including safe scent-dispersion, mosquito and mold defense, stress relief, and more!

Read on for 11 hidden benefits of using oil diffusers.

1. Safe Scents That Make Sense

Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, not overload it with unhealthy chemicals. Electronic diffusers also do not pose the fire risk that candles do. Plus, they contain the added feature of interchangeability, which means you change oil types for different scents and health benefits.

2. Stress Relief

Several lab studies have confirmed that diffusing essential oils like lavender have been shown to reduce stress and help relieve anxiety in medical patients. Preliminary studies have also shown that oil diffusers can help alleviate symptoms of depression.

3. Improved Sleep

Diffused oil has relaxing properties that can help people of all ages fall asleep quicker and sleep more soundly. Electronic diffusers not only have the option to mix and match different oil blends (Try a lavender, Bulgarian rose, and Roman chamomile blend to help with insomnia), they also run at a gentle hum that helps relax an agitated mind. Many also come with an auto shut-off feature to help conserve oils once you have fallen asleep.

4. Appetite Control

Much like gum, oil diffusers can help stimulate the senses in a way that works to curb appetite. New research has shown that diffused peppermint oil can help curb appetite by inducing a satiety response within the body. Diffused peppermint oil has also been shown to increase energy.

5. Bacteria and Mold Killing

When essential oils are diffused in the air, they break down free radicals that contribute to the growth of harmful bacteria. Eucalyptus, thyme, and tea tree oils are especially good for this purpose. Diffused oil is also highly effective when it comes to combating fungal yeast threats, as the oil help makes the air inhospitable for yeasts such as mold. Pine and red thyme essential oils are best for combating mold.

6. Decongestion and Mucus Control

Ever tried Vick’s Vapo-Rub? Its decongesting powers come from active ingredients made from the eucalyptus tree. In principle, oil diffusers work the same way as Vapo-Rub, except they diffuse their decongesting vapor all around the room, not just on your chest or neck. Oil diffusers have been known to cure pneumonia in lab mice.

7. Mosquito Repellant

Nobody likes mosquitoes — but when the trade-off means using repellants full of DEET, a toxic chemical that can be especially harmful to children, mosquito control can often seem like a lose-lose. However, scientists have shown that oil diffusers can be used as a safe and highly effective mosquito repellant. Studies have shown that a diffused oil mixture containing clove essential oil and lemongrass essential oil repelled one type of Zika-carrying mosquito, the Aedes aegypti mosquito, at a rate of 100%.

8. Pain Relief

While applying oils directly to areas of your body may be the most effective way to alleviate pain, diffusing essential oils can also be an effective means of pain relief. When we inhale healthy essential oils, they enter our blood stream and can help internally relieve persistent pain from headaches, overworked muscles, and sore joints.

9. The New Anti-Viral

Research into the anti-viral effects of oil diffusion is now just gaining steam. A recent study showed that star anise essential oil was proven in medical experiments to destroy the herpes simplex virus in contained areas at a rate of 99%. Another study showed the popular DoTerra oil blend OnGuard to have highly-effective influenza-combating powers.

10. Improved Cognitive Function

Diffusing essential oils has also been shown to improve cognitive function. Many essential oils have adaptogenic qualities, which can work twofold in soothing us when we’re stressed, and giving our bodies a pick-me-up when we’re feeling down or sluggish. By working to level out an imbalanced mood, diffused oils also help us to focus. There are also several essential oils which have been shown to help balance the body’s hormones. With prolonged use, these oils can work to repair the underlying causes responsible for hindering cognitive function.

11. Money Saving

With ten clear benefits of oil diffusers already outlined, there is one more that should now be obvious: using an oil diffuser will help you to save money. As an anti-viral, bug repelling, and stress-relief solution rolled into one safe product, an oil diffuser used with the proper oils will save you money on products you might otherwise be buying to help cure those pesky headaches or get your kids to fall asleep on time. If you’re wondering just how affordable oil diffusers can be, check the buyer’s guide to the best oil diffusers — you’ll be sure to find one that fits your budget!
