People Share Their All-Time Favorite Paradoxes

The dictionary defines a paradox in several ways:

  • a seemingly absurd or self-contradictory statement or proposition that when investigated or explained may prove to be well founded or true.
  • a statement or proposition that, despite sound (or apparently sound) reasoning from acceptable premises, leads to a conclusion that seems senseless, logically unacceptable, or self-contradictory.
  • a situation, person, or thing that combines contradictory features or qualities.
For the purposes of this article, we'll be focusing on the first two. It's all thanks to Redditor 301is301, who asked the online community, "What's your favorite paradox?"





"If time travel was possible..."

Time travel. If time travel was possible, then presumably someone from the future would have already gone back in time to change the past. Therefore, when someone says they, for example, would have stopped Hitler, they actually wouldn't because someone already would have made that correction in time. Instead, that must have been, unfortunately, the best possible outcome out of all possible outcomes. Either that or time travel just isn't possible which seems significantly more likely.

"You take a ship..."

Theseus' ship.

You take a ship and replace every single part in it with a new one. Is it still the same ship? If not, at what point does it stop being the ship you knew? Also, if you take all the parts you replaced and build another ship with them, is it the original ship?

"Camus regards..."

Camus regards The Absurd as a paradox. Humans are constantly driven to seek meaning in a world that doesn't appear to have any.

"You receive a strange machine..."

The Bootstrap Paradox

You receive a strange machine and a note that says "This is a time machine, recreate the time machine and send the machine back in time to the day you received it (today)." Bewildered, you set to work to recreate the time machine. When you are done and have tested it, you send the original machine and the note back in time to the day you received it.

You didn't create the machine you received from yourself, where did it come from?

"But any number..."

The Galileo paradox

The sequence of square numbers: 1, 4, 9, 16, 25, 36, 49, 64, etc clearly shows that there are a lot fewer square numbers than there are non-square numbers, as the distance between them gets increasingly longer.

But any number can be multiplied by itself and the result of this multiplication is a square number. So it must also be true that there are at least as many square numbers than there are non-square numbers.

"This one is basically..."

Mine is probably Zeno's Dichotomy paradox although having a favourite paradox is a weird thing.

This one is basically that to reach a certain distance you have to reach half way first. So if the door is 10m away you first have to reach 5m then after that 2.5m then 1.25 and so on and so on which means you will never reach the door.

The other one is The Ship of Theseus, also known as Theseus's paradox. Sometimes also known as the Axe paradox

The axe version is that if you are given an Axe and replace the wooden handle is it the same axe? What if you then replace the blade? How many times can you repeat this process before the Axe is no longer the same Axe?

The cool thing about this is that your entire body is made up of a different set of cells every 7 years or so (as cells die). So can you really say you're the same person you were 7 years ago?

"I was in denial for a good bit..."

How 0.9 repeating is equal to 1 There's lots of different ways to prove it but the simplest for me is this example:

X = 0.9999... Multiply it by 10, so 10X = 9.9999... Subtract 1X from 10X or 9.999... - 0.9999... which equals 9 So then 9X = 9, simplify to X = 1

I was in denial for a good bit when I first heard of this.

"If we assume..."

The Fermi Paradox

It's basically about the existence of aliens and can be summed up as:

"1- The Milky Way contains hundreds of billions of stars, and billions of them are similar to the sun.

2- It is highly likely that some of these stars will have planets that are similar to Earth.

3- If we assume – via the Copernican principle – that Earth is not particularly special, then intelligent life should also exist on some fraction of these Earth-like planets.

4- Some of these intelligent life-forms might develop advanced technology, and even interstellar travel.

5- Interstellar travel would take a long time, but as there are many sun-like stars that are billions of years older, there has been plenty of time for such travel to have occurred.

6- Given all this, why haven't we met or seen any trace of aliens? Where is everybody?"

"But..."

There is a smallest number that is not nameable in less than 18 syllables. But "The smallest number not nameable in less than 18 syllables" has seventeen syllables and names the same number.

gregbard

"There are two paradoxes..."

There are two paradoxes in this one: If the infinite realities theory is true and there are infinite realities, half of them would be a universe where time travel is possible and half where time travel is not possible. But the time traveller is always being sent into a past whose reality is based on time travel is not possible. So as soon as the person time travels, he becomes visitor to a reality where time travel is possible only.

Otherwise, we would never be able to have time travel in this reality. So really, zero realities exist where time travel is possible. And so that makes the infinite realities theory not true. Either way, neither can be true at the same time. So each form of reality in this paradox depends on the other to not exist in order to exist. But they do... and so that makes us Schrodinger's cat at all times.

"Somewhere in the far future..."

Somewhere in the far future we will discover everything that can be discovered. After that most probably the only thing we wouldnt be able to know would be death, therefore humanity is slowly killing itself in its curiosity.

ElFtador

"Let's say..."

Grandfather paradox. Lets say you have a time machine and you travel back in time and kill your grandfather. Well, since he's dead one of your parents won't be born, and then you won't be born either. But, if you're not born, than you can't travel back in time to kill your grandfather, so he's alive, but if he's alive, then you are born and you can travel back in time to kill him, but if he's dead –– you get the idea.

No-regrets136

"No matter what happens..."

Time travel itself is a paradox. No matter what happens, if anyone so much as hears the time traveler, something different will happen. Let alone if the time traveler accomplished what he traveled to do, then he won't have motive in the first place.

Vortex5000

"You meet your past self..."

Your meet your past self and your future self, what is your conversation. Except your future self would also talk to his future self and you. Your past self would talk to his pst self and you. Their past and future selves would have a convo. It would be infinite.

OriginalDoomSlayer

"In other words..."

A sentient, benevolent AI may be driven to torture a perfect simulation of you.

First thing's first: Functionally a perfect simulation of you and you are identical.

Now, the AI wants to come into existence. As soon as it exists, it can help people. However, it can't time travel so it can't go back in time. What it can do is dangle a metaphorical knife over your head. If you know you'll get tortured if you don't do something, you'll be more inclined to do it yes? But if you have no idea you'll be tortured, you won't.

So, by knowing about this potential benevolent AI and the risk of being tortured (Or having a functionally identical copy tortured) you'll be more inclined to help the AI come into existence to avoid punishment, thus making the AI come into existence sooner, thus allowing it to help humanity sooner. There's no sense torturing people unaware of the possibility because torture or not, they won't be more likely to help make the AI.

I might not have done a great job of explaining it, it's a weird concept but once you have it you realise how it works. It's known as Roko's Basilisk.

In other words: A benevolent AI can be driven to do something very not-benevolent for the purpose of more benevolence. And now you know about this possibility, you're going to risk being tortured unless you help it come into existence.

Ewww: People Break Down The Worst Food Sins They Can Imagine

Reddit user Shozo459 asked: 'What’s the worst food sin you can imagine?'

People sharing pizza

When it comes to culinary mashups, nothing is as delectably perfect as a Reese's Peanut Butter Cup. Chocolate and peanut butter in one bite? Heavenly.

Other food combos are not as popular but have a strong contingent of fans like pineapple on pizza or even peanut butter and jelly sandwiches.

And then there are ones that are simply inexcusable.

Curious to hear examples of what foodies absolutely consider tastey bites, Redditor Shozo459 asked:

"What’s the worst food sin you can imagine?"

Trust the preparation.

That Is Soy Not Funny

"ketchup on sushi."

– BattleCatManic

I do believe you'd get your a** kicked for doing that."

– Mattress_Of_Needles

No Sauce Required

"Reminds me of this random sushi joint in osaka. Every pc had the wasabi inserted already. If the piece doesnt have a sauce (like eel), then its premarinated or salted. For normal fish, the chef brushes it with some kind of soy sauce blend."

"He reminded me that soy sauce would not be necessary almost every time he put a new piece on my plate. I asked what the soy sauce bottle is for then and he just shrugged."

"And we're talking about soy sauce not even ketchup."

– gabu87

Tough Meat

"Ok, not sushi, but. (I heard this from my kid....) My ex remarried to a southern woman who fancies herself to be a southern Belle. Instead, she's more of a Momma June. My ex cooked steaks for dinner one night. He will cook meat so it is BROWN straight through. Don't think about asking for it any way, but WELL DONE. In his world, any PINK in the beef means it's nearly raw.😳 So he cooked steaks for them. The wife starts eating and exclaims, 'This steak is soooo good it doesn't even need ketchup' My kid described the meat as being extremely tough and tasteless."

– stalagit68

That's just rude.

Expired Offer

"Eating my fries after I've asked you if you want me to buy you some."

– iggylevin

"So you've met my ex-wife? 'I'm fine' is a small fry and milkshake or frostee. And yes, she should use her words , but she won't, so you can choose to be right or to not have to sleep on the couch over fries and a milkshake."

– Jimmy_Twotone

Chili & Cinnamon

"Although it's not the worst sin imaginable, there's a weird regional dish where i live that involves pairing a bowl of chili with a cinnamon roll. Every potluck I've been to here has it. It's not for me but it's definitely unique."

– MayorOfVenice

Citrus Sin

"Orange juice flavored toothpaste and toothpaste flavored orange juice."

– shhjustwatch

"I gargle with orange juice after i brush my teeth. Power move. Show that plaque who's boss."

– MayorOfVenice

Who does that?

Gimme Some Skin

"Eating the skin off of someone else's fried chicken."

– Upbeat_Tension_8077

"I had a bucket of leftover KFC in the fridge, and my ex SIL came over to my house while I was at work and ate all of the skin off the chicken. I was f'kin pissed."

"Then, on New Years, a few years later, her aunt wanted to make mole and split the cost. I was like whatever and pitched in. I had things to do and got home after it was done. Those f'kin b*tcheses had ate the all of the skin off every piece of chicken."

"I'm so glad I'm not a part of that POS family anymore. If I am ever victimized by chicken skin theft ever again I am going to throw that skinless piece of chicken at them as hard as I can at point blank range and I'm going to aim for their mouth."

– anon

Condiment For All

"Squeezing ketchup on top of a communal plate of fries."

– OverlappingChatter

"I had a boyfriend who would take all of his fries and all of my fries at McDonald’s, put them on the tray and squirt ketchup on top. This infuriated me in part because then the fries got cold so much faster."

– loritree

Wasting food is a cardinal sin.

Grocery Stores At The End Of The Day

"Grocery stores/suppliers throwing out perfectly good food when we there are people starving."

"There is a 2009 doc called 'Dive' that talks about how much grocery stores waste. Edit: (I'm sure there are many others but this is the one that made me aware of the issue)"

– moosegoose2222

"My husband did the samples at Sam's club for awhile and when they did alcohol samples they were told to bust/break the glass bottles into the food that was leftover and to be disposed in the dumpster...so first throw the food in, then break the glass bottles on top when throwing in dumpster."

– Swivel_D

Kevin Sucks

"I worked at a major big box grocery/everything else store for a short time. The a**hole store director was the kind of guy who would make one of the grocery guys get put the floor zamboni on SATURDAY AFTERNOONS to clean up footprints down the aisles when it snowed outside. Of course, it pissed people off."

"The worst thing he'd do, however, was demand that the bakery and Deli have their cases overstocked to 'Grand Opening' standards every f'king day. Of course, only half sold, and the leftovers were not marked down (he hated doing anything like that for damaged boxes or cans because he said it attracted 'poor people'). Instead, it all went into the dumpster at the end of the night. It was usually a half dozen cakes, a dozen loaves of bread, and often 15 - 20 rotisserie chickens. No, employees were not allowed to take home any of it. Oh, and he was openly racist and tried to get a disabled employee fired because he didn't like disabled people working with the public."

"I rage quit that job one day, two weeks before Christmas. I found out shortly after I left that the store director was diagnosed with Parkinsons."

"Rot in hell, Kevin."

– WhitePineBurning

My gripe is more about dining protocol than actual food.

I'm pretty much allergic to alcohol and aside from having the occasional glass of wine, I don't drink often when I go out.

I don't think it's fair when I'm out with a small group of people who each order more than two cocktails and I'm forced to split the bill evenly as the lone non-drinker in the group.

I get it, it's a hassle figuring out the bill to accommodate for me, but I don't mind sorting it out as there are apps to make this easy.

I think it's classy when other members of the group point out that they should chip in more for the bill so I don't have to pay my full share.

But I also hate having to speak up and say, "Umm, can you guys pay for your own drinks since I didn't order any?"

I'm screwed either way since I sound like a loser when I do voice my request or I get passive aggressive afterward for not speaking up.

Anyone know a good solution on how to deal with this?

Anyone who grew up with one or more siblings is bound to have stories of how their siblings occasionally (or frequently) got on their nerves.

Indeed, some people don't even have any sort of relationship with their siblings once they fly the nest.

Those who grew up only children, however, often have trouble accepting that people would cut their siblings out of their lives.

While being an only child can often mean getting your parent's complete love and attention, it also means that you will have to go through many of life's challenges alone, with no peer to turn to for support.

Not to mention, never having anyone to torment and boss around, as many children dream of doing to their younger siblings.

Redditor BroccoliniCarrot was curious to hear what only children thought was the biggest disadvantage of growing up with no siblings, leading them to ask:

"What’s the worst about being an only child?"

Lack Of Playmates

"When I was little, people would give me board games like Monopoly for gifts, and I wouldn't have anyone to play with."

"even Hungry Hungry Hippo sucked playing solo."

"I did master Solitaire though!"- Jesikabelcher

Last One Standing

"When my parents die that’s it."

"I’m just alone."- undertheraindrops

"Family is the most likely group of people to help you when things get tough."

"When your parents pass you have less support."

"Also, aging parents become solely your responsibility."- rubixd

"Taking care of an elderly parent with no one to help."- 3Gilligans

No One To Turn To

"When you are the only one to support your aging parents."- Fantastic_Leg_3534

Forced Independence

"I think because I am an only child I have become used to spending time on my own."

"As a result I am quite antisocial.'

"I don’t mind being around people and can be quite talkative however it exhausts me and I need far too much time on my own to recover."- OstneyPiz

"You become TOO comfortable with being alone all the time, to the point where being alone is the default and interacting with others feels like a chore."

"And that doesn't play out too well in the real world."- DeathSpiral321·

Going Through It Alone

"No one to have a sanity check with."

"My wife and closest friend have siblings and they talk about a close bond with their respective siblings where they could look at the other and effectively say 'mom/dad are crazy, right?'"

"Being an only, I thought some of the sh*t they pulled growing up was normal."

"Having a sibling would have helped counter the gas lighting from parents."- RennSport5280

Making Your Own Conversation Partners...

"As an adult, I sometimes find it difficult to quiet the self-talk because all too often growing up it was all I had."-GreenDolphin86

More For Me?

"I am absolutely not good at sharing."

"Plus and minus was that I got all of my parents' attention, so I had a lot of love and support but also a lot of expectations and not a lot of space to f*ck up."

"Nowhere to hide, no one to blame anything on, and no backup when they were being unreasonable."

"But I also didn't have to split time, affections, or personal belongings with some other gremlin sharing my DNA."=Justheretolurkyall

No One To Keep You In Line...

"No reality check."

"Nobody to confirm that, no, it's not you that's acting nuts."

"Later, nobody to bounce ideas and behaviors off of, nobody to tell you, 'hey, X thinks you're cute' or 'that's not how you ask a girl out, doofus, say this'."

"I should mention that for various reasons, if I had had siblings they would have been older."

"So when I imagine not being an only child, I tend to imagine being a younger brother."

"But I think the reality-check thing would still operate even as an oldest sibling; plus I might have learned to handle responsibility earlier."- ElderPoet

There Is, Indeed, Safety In Numbers

"I am the only son of a single mother."

"I hate this term, but it's called emotional incest."

"Basically my Mom was very young when she had me and there were no men in her / my life."

"As a result, she placed all of that emotional needs of a grown woman on to me."

"My Mom never really raised me as a son."

"At best, she raised me like a little brother she got stuck with after our parents died."

"At worst, she treated me like I was a toxic boyfriend."- ANerdCalledMike

No Scapegoats

"All eyes are on you- can’t get away with anything!"

"Most strict parents ever ( they were older too)."

"Unlike my husband's family growing up with 6 kids."

"Parents hardly knew where the teenagers were or who they were with."- Available_Honey_2951

"When asked by a parent what happened you cannot blame your sibling."- nanodecay

The Eye Of TheBeholder

"People assuming that I was spoiled."- Purlz1st

Having no siblings means never being bullied, teased or tormented, or having to vie for your parent's attention.

Something many people who grew up with older or younger siblings openly say they dream of.

When the going gets tough, however, and these same people realize they always had their brothers or sisters to turn to, they might bite their words and regret ever even thinking of being an only child.

Many couples like to spice things up in their relationships to keep things fresh.

When it comes to bedroom spices, couples tend to add ingredients, like another person to the mix.

But everyone really needs to be on the same page with who they're mixing with.

Or drama can ensue.

Have you ever gone back to your elementary school as an adult and been amazed that everything looked smaller than you remembered?

It's a great example of how our perception of the world around us is shaped by our own experiences and where we are in life.

As a child everything seems big because we're small.

Our childhood perceptions of other things were also skewed. Things that seemed grand luxuries became ordinary or mundane as we aged.
