In this day and age, on the surface level, it seems like we know a lot about how the world, the human body, and the universe all work. And though we do know quite a bit, there’s still lots of room for scientific progress. Some theories aren’t as solid as you might think, and there are plenty of questions that have researchers puzzled.

Internet users took to an online thread to share what they think are the biggest still-unanswered mysteries that we don’t seem to be close to fully solving yet. Read on to get your creative juices flowing and to think about something bigger than "what should I have for dinner?"

It's simple: Dreams are when we roll our eyes back into our heads and see what we're thinking (or so I decided when I was 4). It still makes a bit of sense to me :-)

It’s weird, I have aphantasia, so I can’t visualise things in my mind’s eye, or “picture” a thought. Only found out like three years ago people can actually SEE images while thinking about something. But I have always had very vivid dreams, and I lucid dream a lot. I still remember some dreams from 45 odd years ago, too.

There’s research that suggests it’s a byproduct of the brain ‘washing out’ and replenishing neurotransmitters used up during the day.

Or you have a very vivid dream life and it’s profound and valuable and cool? Or I mean I look at it that way. I think we’re the poorer for it when we can’t remember our dreams. We spent so much of our life asleep; sleep and dream life are a huge part of human life, not just our waking life. A lot of cultures find utility and another way of knowing through dreams.

    It’s interesting that science has no idea what consciousness but so many people state ‘I believe in science, so there’s no after life’. If we don’t know what consciousness we sure as hecky peck don’t know what happens to it after we die. There not being an afterlife (or reincarnation) is as much a belief as the rest.

    That's if I remember right a combination of neural nodes distributed along the body capable of storing simple instructions and patterns the brain can trigger with shorter commands than it would take to send the full command string. Its probably a lot more complicated than I remember though.

    I’ve yet to hear a concise definition of what consciousness is, I.e. what we mean when we say “consciousness”. It seems to consist of mostly subjective experiences, a kind of internal narrative. That makes it practically unmeasurable. People with “locked in syndrome” are conscious but unable to move or speak - so we can’t define consciousness based on observable behavior. Hence, anything COULD be conscious, even rocks and atoms.

    Though we don’t fully understand why people sleep, there are some solid, quality theories that scientists are working with.

    For example, recent research suggests that the primary purpose of sleep for humans may be to remove toxic and metabolic waste from the brain.

    According to one perspective article, if these toxins are allowed to build up, they might compromise brain functionality.

    Meanwhile, researchers at the Washington University School of Medicine in St. Louis found that during sleep, brain cells propel fluid into, through, and out of the brain, cleaning it of waste.

    “These neurons are miniature pumps. Synchronized neural activity powers fluid flow and removal of debris from the brain. If we can build on this process, there is the possibility of delaying or even preventing neurological diseases, including Alzheimer’s and Parkinson’s disease, in which excess waste – such as metabolic waste and junk proteins – accumulate in the brain and lead to neurodegeneration,” explains neurologist Li-Feng Jiang-Xie, PhD, first author and postdoctoral research associate in the Department of Pathology & Immunology.

    Eerie figure wearing sunglasses against a distorted background representing unsolved mysteries and unknown puzzles. Tossing out one less existential, but who pirated the WGN signal with a Max Headroom skit in the 80s.

    Lots of theories, but no real evidence and no one has any idea who did it.

    Kudos to the people involved for actually keeping their mouths shut for 40 years. Makes me think it was one person that did it all on their own. What are the chances of more than one person keeping a lid on that?

    On the one hand, I want the guy(s) who did it to come out and admit it and how they did it. Statute of limitations has to be up right?

    But I get why they don’t. I’m sure the Feds would find some way to convict them of something if they came forward, statute of limitations be d****d.

    I think you had to know the correct angle though to interrupt the signal. And you had to be close enough to overpower the signal (since the corporation had much stronger transmission strength). I saw a TV show on it once and I believe them that it was too sophisticated that you need inside knowledge. Hacking a channel to small area could have been done by a college student at that time, but this was to a wide area. They had to overpower the original transmission from Chicago. Also a theory is they couldn't get into the first station they tried so they tried the 2nd one. The original planned station is mentioned in their message... Something 'news nerds' I forget what they said.

    When I was a kid I assumed that if we managed to somehow ‘teleport’ something ‘outside’ the universe then because of the fact that literally nothing exists ‘outside’ the universe, either the object would completely disintegrate, ie all information about the object remains lost forever and not preserved or the object’s internal energy would trigger a sort of Big Bang event creating a new universe branching off from ours but since the internal energy would be far too little, the new universe would collapse in less than a fraction of a second

    the universe is finite in volume but has no boundaries, similar to the surface of the Earth. If you were an ant walking in a "straight" line on the surface of a balloon, you would travel forever without ever falling off the edge, eventually returning to your starting point. The universe could be a 3D version of this idea, where space is curved (positively) in a higher dimension we don't perceive. Traveling in one direction for long enough would theoretically bring you back to where you started.

    Person wearing boots and jeans sitting by the water, reflecting on mysteries that remain unsolved and puzzling. Restless legs syndrome (RLS) is a condition that causes a very strong urge to move the legs. The urge to move usually is caused by an uncomfortable feeling in the legs. It typically happens in the evening or at night when sitting or lying down. Moving eases the discomfort for a short time.

    According to Dr Google: Restless legs at night are often caused by a chemical imbalance in the brain, specifically involving the neurotransmitter dopamine, which affects muscle control. It can also be linked to underlying conditions like iron deficiency anemia, kidney failure, and pregnancy. Lifestyle factors like excessive caffeine or alcohol consumption, smoking, and certain medications can also contribute. I have found compression socks do help.

    “It is critical that the brain disposes of metabolic waste that can build up and contribute to neurodegenerative diseases. We knew that sleep is a time when the brain initiates a cleaning process to flush out waste and toxins it accumulates during wakefulness. But we didn’t know how that happens. These findings might be able to point us toward strategies and potential therapies to speed up the removal of damaging waste and to remove it before it can lead to dire consequences,” notes Jonathan Kipnis, PhD, the senior author on the paper, the Alan A. and Edith L. Wolff Distinguished Professor of Pathology & Immunology, and a BJC Investigator.

    This isn't a mystery at all: he's a dog. He first appeared in the 1932 cartoon "Mickey's Review," and was originally named Dippy Dog. This was changed to Goofy in 1934, with his first appearance under that name being "Orphan's Benefit." The difference between the two is that Goofy is an anthropomorphic character, and Pluto is not.

    According to Disney, Disney workers, and Goofy's VA, Goofy may have began as a dog, but in his redesign he is a non-dog canine.

    People seem to be missing that you can be a canine but not a dog. Goofy is, offiially, a canine but not a dog. Bill Farmer, one of his most prolific VAs, points this out often. People who have worked for Disney state that he is a Goof, a non-dog canine.

    Spacetime doesn't work like that. Things are getting further apart, but it's not like there is a boundary wall that is being pushed, it's just... the space between everything is increasing. Our current theory is that, eventually, the space between will be so immense that it will literally pull atoms apart and, ultimately, everything will just stop existing. Which may be wrong, because of late some rather big cracks have started to appear in the theories of how the universe is behaving.

    Ancient undeciphered symbols and markings representing mysteries we aren’t getting any closer to solving. We don’t seem to be making any headway in deciphering Linear A, the Minoan writing from. Which is kind of odd because there’s a rather big sample size and it’s in a pretty central location whose people and culture influenced a lot of our touchstones today, but there’s really been no progress to speak of.

    The lack of a big sample size is what is standing in the way. Around 1400 samples, mostly fragmentory and heavily damaged, by comparison Linear B has over 6000. Another reason is that most of those are also quick notes instead of full sentences, and we have zero bilingual references. We have deciphered numerals in Linear A, and have some clue of fractions, and a few are close enough to Linear B to make a guess. Note also that Linear A doesn't encode a known language, we don't know Minoan, and we don't know if all Linear A texts are in the Minoan language.

    There was never an explosion, just an inflation where a tiny packet of energy went from nearly the size of a proton to about a metre in size in less than a second and went on expanding at a constant rate for billions of years. A way of describing the birth of the universe is by saying that the big bang occured everywhere all at once at the same time, first there was nothing and then came everything. And there’s nothing outside the universe (no space, no time, no quantum fields) so the universe isn’t expanding ‘into’ anything, it’s just expanding and this concept is incredibly hard for our simple minds to grasp

    Most assume after he opened the back door, he jumped. I don't believe that for a second, just because he opened it doesn't mean he left the plane right then and there. They did find some money buried in a river bank, but when the calculations were done, the plane had already crossed the area. Meaning, it was probably a decoy. He probably jumped as the plane was making its approach to Reno. And he's probably dead by now, he got away with it.

    Faith says “Before anything existed there was God who created everything we know”. Science then rejects faith because it regards that position as irrational. Then science says “Before the Big Bang, there was either nothing or else an eternal preexisting ‘something’.” But that belief, which hasn’t been proven, is no more rational than the faith position. That’s why many traditional scientists are people of faith who find no incompatibility between faith and science. It’s only the extreme positions that are irrational.

    You have to distract your brain to get rid of hiccups. There’s lots of remedies, too. I don’t get them often, but when I do they last for quite a while. My best remedy for me is eating a teaspoon of hot English mustard or something else hot

    Get a mouthful of water. Hold that water in your mouth while you hold both ears shut and bend over. Swallow (while you're upside down). Hiccups gone. Edited to add: I've used this a lot throughout my life and it hasn't failed yet. You might have to do it twice sometimes.

    I sit up straight, hyperventilate for about 10 seconds and then fill my lungs completely with air. About every 10 seconds I release a tiny bit of air and refill my lungs again. Do for about a minute. It keeps the diaphragm from spasming.

    Person sleeping peacefully wrapped in a blanket surrounded by pillows, representing mysteries that remain unsolved. What does sleep actually do, and why do we need it? On the surface, it seems obvious, but there seems to be a lack of general consensus on why it's necessary. Some species require very little sleep, some require a lot.

    We can point to anecdotes regarding how different animals do it, and even the benefits that come from sufficient sleep.

    We have some good ideas about what sleep does for the body, along with theories as to why this is a necessity. But in terms of a definitive answer, things seem kind of murky.

    It is known that sleep is a necessary biological process that allows the body and brain repair, restore, and recharge. During sleep, waste is removed from the brain. Other biological processes occur so all this is what sleep actually does.

    Intelligence is a concept we understand. Animals don't know what intelligence is, and yet they might or might not use it. What are some other concepts similar to intelligence that we have no idea exist and we have no way of knowing they exist. It's a big assumption that we can understand everything in the universe using intelligence.

    Intelligence is knowing how to do what one needs to thrive as a species. It includes adapting to changes in one's environment. Basically, every extant life form is as intelligent as it needs to be, with the arguable exception of humans.

    WE think we are smarter than we are because we have thumbs and build. It's our measurement of intelligence. "primitive" peoples = minor building. We can't understand animals and have only recently learned they communicate, language, names, emotions, same as us. Why would we even know how smart they are? We test our abilities, not theirs. In our way. Even so some results have been a shock to researchers.

    A smiling couple posing closely together, capturing a moment amidst unsolved mysteries people continue discussing. Not biggest on a universal or global scale, but locally near Philadelphia, a couple has been missing since 2005 and vanished without a trace. They were at a bar and after leaving were never seen again. Car missing, no activity on phones or credit cards. Just gone. A lot of speculation but so far no leads and it bugs me. If interested just google “missing South St couple Philadelphia”.

    A black hole is not actually a hole, so why assume one could "enter" it? The other side is just the other side. Like the other side of our sun from where we're currently located. We do know that we could not currently survive approaching closely to a black hole, because the gravity would stretch us. I think OP is thinking a black hole IS a "worm hole" - that that's a fact, but we just don't know how worm holes work yet.

    It's not a hole. At its center is an incredibly dense dead star and it's gravity is so strong it pulls everything to it, where things violently become part of it. Bad analogy, but think of the world's strongest magnet and everything around it being made of steel. Get the steel too close and it slams into the magnet.

    Contagious yawning is due to empathy and mirror neurons. The more empathy that you have, the more susceptible you will be to others' yawns, and mirror neuron responses. Mirror neurons cause animals to mimic behaviors in others to help them communicate and learn. Since psychopaths don't feel empathy, yawns aren't contagious to them.
