Did You Know...

    Did you know that Astronauts orbiting Earth do not float as a result of there being no gravity ? They appear to float because they are falling.

    The gravity in Earth's orbit is about 80% of what we experience on the planets surface. The reason they appear to float is because they are in constant free fall pulled back down by Earth's gravity. But because they are travelling at speed and falling towards the horizon they fall around the Earth rather than straight back to it.

    Anyone got any other interesting facts ?

    I like to watch fact videos on youtube. Here is a bunch off the top of my head.

    - Barcode scanners don't scan the black lines. They scan the white space between each black line.

    - if the weather conditions are right on the day, 20 to 25% of fog in San Francisco is actually smog that blew over from Chinese factories.

    - A pilot and co-pilot must eat different meals on a flight in case of food poisoning.

    I dont know if this is a fact, it just seems logical:

    it would take a pint of Guinness 40 minutes to settle properly on the moon, because the gravity is 25% of what it is on Earth.

    Well, not on its own it cant. Youd just have wet beams.

    Combined with fire though it could soften them, resulting in a couple losing structural integrity.Then the fun starts.

    If every person in China stood on a chair and jumped offat the exact same time (taking into Account time differences) then they would all land on the ground at the exact same time too and no one else on earth would notice or care.

    Beer was classified as a soft drink in Russia until 2011 and thus could be bought by anybody.

    Our galaxy (or at least the thick band of stars visible in clear skies) is called The Milky Way because of Greek mythology. According to them, one day Zeus brought Hercules to his wife Hera to be breastfed while she slept. She woke to find him feeding and quickly tore him away from her breast (as he wasn't her child), splashing her breast milk across the sky.
