On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin landed on the moon while fellow astronaut Michael Collins orbited in a command module. Conspiracy theories denying the moon landing soon started.
why stars are not visible in photographs taken on the moon
the almost 400 kg. of moon rocks the astronauts brought back
why the lunar landing module did not produce any flames when it took off from the moon
Films of a flag flapping on the Moon mean there must have been wind blowing, but there’s no atmosphere on the Moon
ps. i think its top secret that whether its a myth or not. but mythbuster did a show on it and here are there conclusions.
Myth: They [parents] used to say that sitting too close to the TV screen is bad for your eyes…
Well in actual fact there is no empirical evidence to say that sitting down right in front of the TV set damages someone’s eyes. The American Academy of Ophthalmology (AAO) says that kids can actually focus up close without eyestrain better than adults, so they often develop the habit of sitting right in front of the television or holding reading material close to their eyes. However, sitting close to a TV may be a sign of nearsightedness.
Regardless of this, i still tell my daughters not to sit too close.
Most myths had a reason behind why it came in to being. with this one that you brought up I’ve wondered what could’ve motivated it. Here are a few reasons I came up with:
TVs picture quality is a LOT better than it was 30-40 yrs ago. With flat panels the strain on the eyes has been reduced quite a bit.
Sitting too close to the TV may not be bad directly, but if you think about it the eyes do use a lot more muscles to look at things up close. Ofcourse the kids are better at it but that may tire out eyes over extended periods (may even cause headaches). Plus if you are that close then you don’t see anything else besides the TV, peripheral vision or otherwise. Sitting far away you tend to look at other things (get distracted) which is prob a good thing, i.e giving the eye muscles to relax as you look away at things further and different (screen saver syndrome)
Over all there is a corelation for between people who read a lot with eyes problems early on in life, so I think that has to do with #2.
