9 Myths about Space We Need to Stop Believing ...

Pretty close to home, this is one of the myths about space that everyone seems to buy into. The reality, however, is that the sun isn’t actually burning – it’s glowing. This is quite an important difference, since the reactions inside the sun are nuclear, not chemical in nature.

While sci-fi makes space travel look relatively fast and easy, it actually takes even light about 4.3 minutes to reach us from Mars, and that’s “only” about 78 million kilometers. With our current technology, it would take the fastest known craft about 150-200 days to reach the Red Planet.

Meteor showers and asteroid belts are considered deadly for space travelers. In reality, if we look at the asteroid belt between Mars and Jupiter, objects are hundreds of thousands of miles apart, and the chances of hitting anything is about 1 billion to one.

This is probably one of the most ridiculous myths about space ever encountered. Sound needs a denser medium to travel, such as the gas in our atmosphere, and in space you can’t find two air molecules that close together.

Many still believe that the moon has a side that has never seen the sun and is always covered in darkness. The truth is that the moon is tidally locked with our planet, which means that the same side will always be facing the Earth, not the Sun. There's no dark side of the moon, as all sides receive sunlight at various points.

Like many other space myths, this is another overinflated idea – literally. While sci-fi movies might tell us we’d explode in the vacuum of space without a suit, science shows that a person could potentially survive space for about 30 seconds, and there would be no explosions involved.

Nope. The winter cold and summer warmth are actually due to the tilting of the Earth’s axis. The Earth’s distance from the Sun plays an extremely small role here, despite our planet’s slightly elliptical orbit (which isn’t a myth).

Black holes seem pretty scary, especially with sci-fi epics portraying the way they can destroy entire planets in mere minutes. However, they are only as strong as their mass allows them to be, and if our Earth was orbiting a black hole as heavy as the sun placed in the same location, our orbit would not be disrupted at all.

The Apollo astronauts’ ability to see the Great Wall of China from the Moon is probably one of the widest circulated myths about space out there. The truth is, it’s hard enough to see the Great Wall from low Earth orbit, and it is simply impossible to view it from a greater distance without a telescope.

This list might come as a disappointment to some, but the reality of it is that space is a grand enough marvel even without these myths. Can you think of anything more to add to the list?
