5 FALSE SCIENTIFIC FACTS EVERYONE KNOWS

Well, you have to admit that both the Internet and the word of mouth can make us believe in almost anything. Have you ever thought that lots of “scientific facts” that we hear or read are pure lies? Don’t let the wrong facts settle in your mind! Here is what you need to know:

    1. The Big Bang theory explains where the universe came from

      Wrong! Unfortunately, that’s not actually what the Big Bang theory describes. Rather, it tries to explain the expansion of the universe: it doesn’t say how & where the universe appeared but what the universe did to become gigantic.

    2. There’s no gravity in space

      Wrong! Gravity does exist in space! We’re not saying that astronauts are faking weightlessness. Rather they are experiencing microgravity, or gravity that’s quite weak in comparison with what we experience on Earth.

      If an astronaut were to slip on a banana peel in the space station, he definitely would not fall down. Instead, the microgravity would make him fall at the same rate that everything else would be falling. Hence the floating effect.

    3. Being in a vacuum causes our eyes to pop out

      Wrong! A human body or any similar organism won’t explode if put into a vacuum. Rather, the lack of oxygen would cause us to lose consciousness and die after just a few minutes.

    4. Lightning never strikes the same spot twice

      Doesn’t sound right, does it? In 2003, scientists found that lightning doesn’t just strike one place when it hits the earth. On average, it hits 1.45 places at a strike (source: Goddard Space Flight Center). Moreover, your chances of being hit by lightning are actually 45 percent higher than the number of flashes, because it does hit in 0.45 more places.

      And yeah, lightning definitely strikes the same place twice. Sometimes even thrice.

    5. Summer’s hotter because you’re closer to the Sun

      Totally inaccurate! It’s not the proximity of your hemisphere to the Sun that makes summer warm and winter cold. It’s the angle that the rays of the Sun hit us. In summer, they hit right on us. In winter, they are slanted down, away from us. The picture beloow illustrates it perfectly:
