largest structure in the universe discovered

[cityboi]

No one can even begin to fathom the size of the universe but largest structure found so far is still just a little spec in the universe. The structure is a large quasar group, a collection of gigantic galactic cores held together by a supermassive black hole. The group, or LQG, stretches 4 billion light-years across. (the earth is 4.5 billion years old) A light year is how long it takes for light to travel in an earth year. At the speed of light it would  take 4 billion years to get from one side to the other! For comparison, our galaxy, the Milky Way, measures roughly 100,000 light-years wide. The nearest galaxy to our own, the Andromeda galaxy, is 2.5 million light-years away, less than one-thousandth of the width of the LQG. And as I said before LQG is still just a little spec in the universe and there are billions of galaxies in the universe. Just one of those galaxies can contain 1 trillion stars. Our own Milky Way galaxy contains 400 billion stars. The planets around all these stars in all these galaxies is uncountable. There is no way we are alone in the universe. Because of this, there would have to be billions of planets with  intelligent life. The vastness of space just makes us feel alone. Just remember when you look up at the stars at night, you are actually seeing light from the distant past. Some of the stars that you see in the sky may not even exist anymore. It's like turning off a leaky faucet. The water is turned off but the water still drips. BTW our galaxy and the Andromeda galaxy are expected to collide in 3.75 billion years. Moons revolve around planets, planets revolve around stars. Stars revolve around the center of galaxies. Galaxies revolve around super massive black holes. It makes you wonder what the super massive black holes revolve around and how many billions or even quadrillions of super massive black holes (all with galaxies & stars) there are. The universe is so vast, we may never have the perspective to find out!
