How the Universe Works

The Universe formed from a big ball of matter exploding.  This is known as the Big Bang.  The Universe’s bang did not sound like anything.  Because there is no air in space, that sound can’t travel.  Inside a vacuum, there is no sound.  If I were talking inside a vacuum, then this is what I would sound like:

{ n o t h i n g . }

That’s what I would sound like.  Supernovas are part of a dying super star.  But a hypernova is when a super giant turns into something called a hypernova—you heard that at the beginning of this sentence.  Then the hypernova forms into a black hole.  Black holes can even bend light!  Black holes rip things apart and the laws of physics break down and do not apply and time stops.  Anything that falls into a black hole gets spaghettified.  But in a super massive black hole, they rip apart stars.  And there is one at the center of our galaxy.  And the Andromeda galaxy.  And now, how the universe formed…

At the start of the universe, all matter was packed into an incredibly hot, dense ball.  And then, in fractions of a second, it imploded.  Then, streams of things that travel at the speed of light went everywhere!  And then, here is a battle between matter and anti-matter!  Anti-matter does the opposite of matter. Like, pretend there is an opposite of me…and if we shake hands together, we would all explode.  It was a really close battle.  Anti-matter had less the matter of matter.  And then, the first stars formed. But then, they exploded, forming black holes. And there was this one super massive black hole and the others went inside it as the super massive black hole ripped them inside.   And then it let in lots and lots and lots and lots of gas.  And it kept on going until the super  massive black hole could take no more gas. Then, it made the most powerful flame-throwing thing in the universe—streams of x-rays and gamma rays—until when things calmed down, it formed the very first galaxy.

As other galaxies formed, the planets started out as planetessimals, or really small planets. Until the planetessimal pieces knocked into each other and these became planets.  They all started out as ice, but the ones nearest to the sun heated up. Then we ended up with the small, rocky planets: Mercury, Venus, Earth and Mars.  Farther away from the sun, it was cold enough for gas to hang around, so we ended up also with the large, gassy planets: Jupiter, Saturn, Uranus, and Neptune.  And I did not forget Pluto, Ceres, Haumea, Makemake, and Eris.  And then, the planets started to orbit.  Dwarf planets and Mercury have an oval shaped orbit, while the other planets have a round orbit.  A few billion years later, guess what happened?  Life evolved on Earth! And maybe on Mars! 

Saturn started out with 67 moons, but then, 7 of of the moons crashed into the planets, making the rings around Saturn!

Jupiter also had 64 moons, but then one of them crashed into the planet and formed a faint ring.  The same thing with Uranus and Neptune!  Jupiter now has 63 moons and Saturn has 60.  Uranus has 27.  Neptune has 13. 

By the way, Haumea does have 2 moons but Pluto has 3.  The two moons Haumea has are named Hi’aka and Namaka.  Pluto’s three moons are Charon, Nix, and Hydra.  Eris has one moon named Dysnomia.
