Hollywood, friends, and family have perpetuated these 35 science myths for years. But it's time to set the record straight.

Is there fire in space?

Does tequila really come with a hallucinogenic worm?

Can you overdose on Vitamin C?

The answers to these questions will surprise you.

For this list, we used Wikipedia's great list of "Common Misconceptions", this great video from Mental Floss, and our brains. You can find the source of our facts under the images.

Contrary to what you learned in grad school, there are four states of matter, not three. Solid, liquid, gas, and plasma are the four states of matter you see everyday.

Although most of us have only experienced gravity in the downward direction, gravity is not a downward force. Simply put, gravity sucks! And it sucks in all directions and dimensions.

Monosodium glutamate (MSG) is a flavor enhancer in many foods and is safe to ingest. MSG is often associated with Chinese Restaurant Syndrome which describes a series of undesirable side effects like numbness at the back of the neck and a general sense of weakness. Eating to excess is more likely to cause these symptoms than consuming MSG.

Back in the day, sailors used the north star, Polaris, for navigation not because of its brightness but because it is the only star that does not appear to move over night. Polaris is not a single star, but is a triple-star system. None of these stars are even in the top 10 of the brightest stars in our night sky.

Contrary to popular belief, house flies do not have a life span of 24 hours. So, if you think it's better to wait for your uninvited house mate to die instead of chasing it down, think again. The common house fly can live for up to a month!

One dog year is not equivalent to seven human years. Dogs age most quickly during the first two years and after that it greatly depends on the dog's breed. For some dog breeds, one year is equivalent to a 14-year-old human.

Tequila and mezcal shouldn't come with worm at the bottom. Only certain types of mezcals, another type of alcohol made from the agave plant, like tequila, contain the worm — and it's actually an indication of low-quality alcohol or a marketing trick. The worm is a moth larva and its presence indicates infestation.

Gun silencers cannot muffle the sound of an exploding weapon to a whisper. While it does work to muffle the weapon, the result is about as loud as a police siren, which is still one hundred times less loud than the gun without a silencer.

Black holes are not actually the color black. They look black when we observe them because they emit no form of visible light. One of the only ways we know black holes exist is because of the gravitational pull they have on stars that otherwise appear to be orbiting empty space.

Blondes and redheads are not "going extinct." Genes do not go extinct. Recessive genes, like the gene for red or blonde hair color, can be carried from generation to generation without emerging as a hair color.

When our Sun reaches the end of its life in about 4 billion years, it will not explode, contrary to popular belief. It will slowly expand, eventually swallowing Earth in the process.

Sunflower heads tend to face a certain direction and the myth is that they track the Sun as it moves across the sky throughout the day. Although sunflower heads are fixed, their buds do, indeed, track the sun before they bloom and the resulting direction the heads face is a result of this behavior.

Daddy longlegs spiders can, in fact, pierce human skin with their small mouths. But don't worry, they also are not the most venomous spider in the world and the small amount of venom they carry will cause only a mild burning sensation for a few seconds and nothing more.

Many interrogators would like to believe that truth serum, like amytal sodium, inhibits their subject's ability to lie, but that's simply not the case. Truth serum creates a similar effect to being drunk, which might loosen your tongue but does not make you incapable of lying.

Don't think that you can ingest countless amounts of Vitamin C and be alright. The upper limit for an adult is 2,000 milligrams a day. While a mega-dose of Vitamin C will not likely kill you, it will cause diarrhea, nausea, vomiting, headache, heartburn, and other unpleasant side effects.

Radiation is often associated with nuclear radiation, creating the misconception that all radiation is bad for you. Light is a form of radiation as well as microwave radiation that cooks your frozen dinners. There is a wide range for radiation and only the highest energy radiation is harmful to human tissue.
