My name is Yoshikage Kira. I'm 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don't smoke, but I occasionally drink. I'm in bed by 11 PM, and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning. I was told there were no issues at my last check-up. I'm trying to explain that I'm a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn't lose to anyone.

Thanks for letting me take this quiz! I got 13 correct- not too bad but I feel I could done better! Anyway, I'm quite fascinated in the subject of astronomy. I like gazing up at the sky on a clear night; there's so much to see. I also like testing my knowledge too. Once again, thanks!

In the last year or so there is research (e.g U of Texas) favoring a 2 trillion galaxy universe.

Man your quiz really nice. But some of your question's answers were so stupid . For example in q16 the answer would have been extremely small black holes beacause in large black holes the have a supermassive event horizon through which you can travel for a large amount of time untill you reach the centre where your body will get streched apart because of singularity. Again in q18 the largest galaxy is IC1101 . In q19 the answer will be VYcanois majornis.

The solar system is located in the minor arm Orion, not Sagittarius. Eta Carinae is not the largest known star, though it does have immense clouds of gas surrounding it currently, The largest known star in the observable universe is UY Scuti, with VY Canis Majoris coming up second. Somewhat outdated but still a good quiz :)

This quiz is clearly outdated.๐Ÿ˜“I would all of them correct if it was not for some stupid answers. We are in the Orion arm and we are in the virgo cluster. And there are only 50 billion galaxies? There is far more and around 2.5 trillion that are observable. Jeez there are around more than 90 quadrillion in the universe and its expanding!! ๐Ÿ˜“ some people not too long ago said they 20/20 or at least 17/20. That means they lied or are reading very outdated books. Im only 11 and I know this stuff. This quiz was made by an adult .But I appriciated the work into it๐Ÿ‘Œ. Not to mention the largest star is or the largest galaxy. Other wise I liked it.๐Ÿ”ญ๐Ÿ˜
