10 Common Science Myths I
CAN'T Believe I Thought

Time and space are concepts that our simple human minds are just beginning to understand. So naturally we're bound to make a few mistakes here and there. Here are 10 science myths that some of us thought were true but were ultimately bogus!

The 24 Hour Lifespan

You tried swatting that pesky house fly but you missed every time. No problem. House flies have a life span of 24 hours. Right? Wrong. Most house flies can live as long as an entire month. So keep your swatter handy because it's going to be a 4-week challenge.

We know that what goes up must come down. So naturally we assume that gravity is a downward force. But it's not. In fact, gravity can pull from all sorts of directions and the force varies between dimension and direction itself.

Lightning never strikes in the same place twice except for all those times when it quite commonly strikes in the same location, specifically in areas with tall buildings like the Empire State Building or the Eiffel Tower and of course huge trees. So next time you're caught in a storm, find shelter fast!

Five Second Rule

When food drops on the floor, people assume that it's okay to eat if they pick it up within 5 seconds. But in reality, floors are full of germs. So when you pick that peppermint candy, cookie or potato chip from the floor and put it back in your mouth you're also getting an unhealthy dose of germs to challenge your immune system … even if it was on the floor for 2 seconds.

Popping In Space

Due to Hollywood's imaginative storytelling on television and film, people have come to believe that a human body will pop when exposed to outer space. But a human can survive up to 30 seconds as long as they exhale. This will prevent their lungs from bursting. Ultimately, the lack of oxygen will be what kills them.

Gravity In Space

We know that astronauts float in space so we automatically assume that there is no gravity in outer space. But the truth is that they only appear to be weightless because they are hovering in Earth's orbit. When the shuttle goes into orbit about 250 miles above the planet, the gravity on the ship drops to 10 percent. But some gravity is better than nothing.

Brain Cells

For those of you who watch a lot of TV but fear the myth that claims it will kill all your non-regenerative brain cells, we have good news. In 1998, scientists discovered that stimulating your memory and learning centers can result in the creation of new brain cells. So start buying some crossword puzzles or go back to school.

The North Star

Some call Polaris (aka the North Star) the brightest and has been used by sea voyagers to guide them for centuries. The truth is that Sirius is a lot brighter than Polaris but the latter always stays fixed in the night sky unlike other bright stars. This makes it the ideal navigational point … if you don't have modern technology onboard your boat.

Pennies Dropped

So you are a major moron or a psycho and go to the roof of a tall building and throw a penny in the air because you heard that it could kill a pedestrian when it picks up enough speed. Fortunately, for the general public, this isn't true. The penny will reach speeds of about 50 mph, which is enough to injure someone but not to the point where it would be life-threatening.

We assume that evolution means that species transform into a more advanced version of their original selves. But when you look at certain reptilians (who descended from the dinosaurs) or sharks or fungi, you'll notice that evolution in some species was more like a devolution.
