    This is the Sun compared to the biggest star known.



    Then think how big the Sun is compared to Earth.

    And how big the Earth is compared to you and me.

    That is quite a scary thought.

    Given its size, I'm assuming this mega star is over 9000 billion lightyears away from us, right?

    Thinking about the universe actually does scare me sometimes, like how phobias scare people, how big it is and all...

    "If the Earth were to be represented by a sphere one centimeter in diameter, the Sun would be represented as a sphere with a diameter of 109 centimeters, at a distance of 117 meters. At these scales, VY Canis Majoris would have a diameter of approximately 2.3 kilometers, assuming the upper limit estimate of the radius of VY Canis Majoris." ..******* crazy. i do feel small thinking about that.

    4,900 light years

    so around 49,000,000,000,000,000km

    OHH, is this the 'Dog star'?
    My mum told me the dog star is the brightest star in the sky, and given it's size, and a quick wikipedia of it, it says it's one of the most luminous. So, is this the star we would usually call the Dog star?

    thanks by the way, I'm going to be thinking about this all night now...

    Vacuum metastability event
    See also: False vacuum

    If our universe is in a very long-lived false vacuum, it is possible that the universe will tunnel into a lower energy state. If this happens, all structures will be destroyed instantaneously, without any forewarning.

    Dog star is Sirius, and not that thing above. See here
    http://en.wikipedia.org/wiki/Sirius

    Anyway, the universe and our complete insignificance is a brilliant topic to ponder when sat in the bath or in bed. The figures are mind boggling, as are many of the unanswered questions. Some thing humans just wernt ment to comprehend.

    Tbh I don't feel insignificant, compare a human being to a particle. Say a electron - 1/1836 of a proton size, now compare that electron with the biggest star know. Now that's insignificant.
