Before Howard met Bernadette, he was a mess. But together, well, he's her mess.&nbsp;When Howard and Bernadette became a duo, they not only elevated each other, they elevated the show.

However, while science has managed to discover some fascinating things about both earth and space, there are a number of surprisingly common things it has yet to fully understand.&nbsp;These aren't the “big think” mysteries like reconciling quantum physics and relativity, or understanding the fundamental nature of time itself. These are things you'd expect scientists to have a handle on - like how bicycles work, or why sand is soft. Vote up the concepts you were sure humans had figured out by now.

Sheldon, Penny, Raj, Howard, and Leonard met various personalities during the sitcom's 12-year run, which includes cameos and appearances from many big-name guest stars.The Big Bang Theory is one of the few shows where actors don't need to play other characters to appear in cameos; the focus on geek culture means they usually just play fictionalized versions of themselves. Most of the guest stars are from franchises like Star Trek and Star Wars, along with a few others that fulfill the requirements to be part of geek fandoms.

In all fairness to dinosaurs, there is nothing to fear from them. They are all dead. Unless you count the <a href="https://www.ranker.com/list/birds-are-just-dinosaurs/bruce-maisy" target="_blank">birds they have evolved into</a>, you simply aren't going to have a run-in with a T-Rex unless it's at a museum. That being said, there are hundreds of species of dinosaur that are absolutely terrifying in appearance—of which we'd be afraid to run into. Jagged rows of teeth, powerful armored tails, and their sheer size make a fear of dinosaurs a healthy proposition.Some of the scariest dinosaurs are those that preferred to eat meat, so you won't find any herbivores on this list. That isn't to say a colossal animal who preferred to eat leaves wasn't something you should fear; a Brontosaurus could step on a person and probably not even know it. When it comes to fearing a scary dinosaur species, it's all about thinking one is chasing you.Thanks to Michael Crichton and Steven Spielberg for making them realistic enough on screen to actually fear them, people who have watched any of the&nbsp;<a href="https://www.ranker.com/list/best-dinosaur-movies/all-genre-movies-lists" target="_blank">Jurassic Park&nbsp;films</a> likely have an idea of which are the most dangerous dinosaur species to humans. Were we to travel back in time and stumble upon one, or if some careless scientist somehow figures out how to clone them (which seems plausible),&nbsp;perhaps it's wise to fear these colossal (and often ugly) monsters from the past.

Let&#39;s face it, bears are cute animals. OK not the biggest bears, but their cubs are absolutely adorable and every part of our nature instructs us to pick them up and cuddle with them. Unfortunately, if you do this, you might learn the lesson Leonardo Dicaprio&#39;s character learned in&nbsp;The Revenant: do not, under any circumstances, be anywhere near a bear cub&mdash;much less ever pick one up. Each and every one of us should have a healthy fear of bears. It&#39;s natural to be afraid of bears and that has a lot to do with their sheer size and ability to kill with a single swipe.

Seeing as they are so <a href="https://www.ranker.com/list/bears-doing-human-things/joswo" target="_blank">cute in appearance</a>, a lot of folks may not realize it, but bears are really dangerous to humans. They are the largest carnivore on land and dominate their respective ecosystems as the alpha predator. Generally speaking, you really shouldn&#39;t mess with just about any bear species as bears are aggressive animals.&nbsp;

Bears aren&#39;t going around eating people or anything; they subsist mostly on berries, fish, and other items found in their environment.&nbsp;However,&nbsp;they are highly territorial animals who will use their gigantic claws and teeth to get their point across in a deadly way&mdash;should any human come snooping around. The scariest and worst types of bears that attack humans are pretty much every species of bear. They know they are tougher than you and will assert themselves if threatened so it&#39;s ok to be afraid of bears... especially the ones on this list.

Think freshwater lakes, rivers, streams, and creeks are safer places to swim than the mysterious wine-dark sea?&nbsp;Scary animals that live in fresh water put that theory to rest!What exactly are these terrifying creatures? They range from <a target="_blank" rel="noopener noreferrer" href="https://www.ranker.com/list/scary-amazon-animals/nathan-gibson">Amazonian animals</a> to brain-eating parasites, larger-than-a-human alligators, and even a shark -&nbsp;yes, a&nbsp;relative of Jaws - capable of living in fresh water.&nbsp;It's important to note that most of these animals are harmful to humans only when they feel threatened. But, if someone is having a good time at the local swimming hole, they may not notice an aquatic or semi-aquatic neighbor -&nbsp;and unwittingly provoke it into defensive attack mode.Like the <a target="_blank" rel="noopener noreferrer" href="https://www.ranker.com/list/scary-facts-about-the-great-lakes/erin-maxwell">eerie info about the Great Lakes</a> we recently learned, these facts about creepy critters prove that freshwater environments can be just as wild, mysterious, and unsettling as the briny ocean.&nbsp;Read on and vote up the lake creatures you wouldn’t want to run into.

It's common for&nbsp;scientists to publish some report that says dinosaurs and birds had a lot in common physically. For some people, that might make dinos seem less terrifying. But in some cases, it makes birds seem a little scarier.&nbsp;One example is the shoebill stork, a species that many consider the&nbsp;<a href="https://www.ranker.com/list/scariest-birds-list/ranker-science" target="_blank">scariest bird</a> to walk the planet.If you’re looking for a modern-day dinosaur, then&nbsp;the elusive shoebill stork might be the closest you'll get.&nbsp;The shoebill bird is native to the marshes of East Africa. It's a&nbsp;masterful hunter and endangered species, but&nbsp;it's also a frightening creature to&nbsp;the inhabitants of the lands it occupies. If you want to understand just how bone-chillingly terrifying nature can be, then here are some reasons why the shoebill stork is&nbsp;a scary bird that&nbsp;you'd never want to encounter.

One of humanity's most primal fears is that there is something crawling up your back right now. Seriously, you might want to check that out because a fear of insects resides in just about every one of us. There's good reason for that: there are some insect species who have absolutely no problem causing us real harm and even killing us!Humans may think themselves the dominant lifeforms on the planet, but there are millions of species of insect species in every nook and cranny of the globe. Some of the <a href="https://www.ranker.com/list/terrifying-insects/jacobybancroft" target="_blank">scariest types of insects</a>, which attack humans, serve up a healthy dose of fear.The main problem with most insects is that you don't have to worry about one insect that attacks humans, you have to worry about a <a href="https://www.ranker.com/list/bug-infestations-in-history/mike-rothschild" target="_blank">swarm of nasty bugs</a>. You might be able to swat one pesky bug, but 10,000 of them? That's a different story. Some of the scariest bug species around are rather ugly, which is one of the reasons people fear and despise them, while others are surprisingly beautiful. Despite their appearance, there are several species of insects that are dangerous to humans and should be avoided at all costs—and many&nbsp;are found on this list.

Dogs are man's best friend, but even a <a href="https://www.ranker.com/list/cute-derpy-dogs/whitneysmoore" target="_blank">cute and cuddly</a> little puppy can grow up to be a deadly killing machine! While many people own dogs, there are a large number of people afraid of dogs. This fear goes back thousands of years and likely extends to human interactions with the wolf. We know instinctively that dogs can be dangerous, but we love the little furballs anyway.&nbsp;That doesn't mean there aren't <a href="https://www.ranker.com/crowdranked-list/the-best-dog-breeds" target="_blank">breeds&nbsp;of dogs</a> that aren't dangerous to humans. There are quite a few kinds of dogs&nbsp;many people consider to be scary and dangerous due to their aggressive nature. We aren't suggesting all dogs of the breeds listed here are dangerous, but due to documented cases, some individuals within a breed have proven to be dangerous to humans.&nbsp;These scariest types of dogs are why many people are afraid of them and in some cases, they should be. Approaching an unfamiliar dog of any breed can be&nbsp;dangerous, as plenty of&nbsp;dogs can&nbsp;attack humans. While most do so only when threatened, some will attack completely unprovoked and, when a powerful dog bites into your neck, it's likely you won't be getting up anytime soon.

Under the Sea

An estimated 71% of planet Earth is ocean, home to more than 230,000 species of fauna and flora. This photo gallery includes impressive pics of over 75 marine invertebrates, including cephalopods, crustaceans, mollusks, echinoderms, and more cool animals. Octopuses, crabs, jellyfish, and starfish may be the main attractions at public aquariums, but there is much, much more to the deep blue sea. For example, there are more than 3,000 unique species of nudibranch (NOO-dee-brank) sea slugs, many in impossibly bright colors that warn predators that they are poisonous. On the other end of the spectrum, the predatory flamboyant cuttlefish and peacock mantis shrimp boast bold colors to distract prey while they use unique tactics to stun and kill them. It's all very ghastly. Enjoy these fascinating photos of sea creatures you never knew existed, and never forget that the ocean is a dangerous place!
