  • It’s so absurdly big. Our galaxy (the Milky Way) is estimated to have between 100 and 400 billion stars in it. For a long time we thought our galaxy was all there was, it wasn’t until 1925 when Edwin Hubble was able to prove that M31 was not a nebula or cluster of stars in our galaxy, but in fact an entirely different galaxy altogether that we realized there are more galaxies out there.

    Look at the Hubble Ultra Deep Field picture

    This was a taken by pointing the Hubble Space Telescope at a basically empty bit of space 2.4 by 2.4 arcminutes in size (for comparison, the moon has an apparent size of about 30 arcminutes, or half a degree). So an absolutely tiny part of the sky. It contains about 10.000 galaxies.

    The observable universe is estimated to have between 200 billion and 2 trillion galaxies in it, with on average about 100 billion stars per galaxy. It’s absolutely mind blowing.

    Every cat I’ve had during my life regulated their own food intake. The important bit is that they consistently have food available. Once they learn to trust that it’s always there they don’t over-eat.

    They also get a pouch of wet food every evening. Although it is very important to them that they get this (my cat sits next to her bowl and starts staring at me with this “I’m not angry, just disappointed” look about half an hour before dinner time) they don’t even always finish all their wet food.

    It kind of depends on the season how much they eat. In winter they empty their wet food bowls, in summer they eat about 70% and leave the rest.
