Sagittarius A*

 Once upon a time
 The first time we had time 
 Big Bang!
 And there went superheated rocks and gas
 Over millennia they formed a massive star
 Millions of times more massive than our sun
 It burned and burned for billions of years
 Until one day it collapsed on itself
 Its own gravity pulled it and it ate itself
 Making it spin madly on end
 It began to pull gas, rocks and stars
 Consuming them whole into its gravity core
 It grew and it grew massive and faster
 Its gravity pulling stars from farther and farther
 Spaghettification for everything nearby
 Even light traveling at light speed could not escape
 Its event horizon materialized
 With an accretion disk of all that it eats
 The only visible part that you can see
 It’s so dark in fact, it turned black
 The bigger it gets, the smaller its core
 All those stars compressed into a tiny pinhead
 Singularity as it’s known
 It’s not a vacuum, it’s not a hole
 It’s not a portal or a wormhole
 It doesn’t travel through space
 In fact it just stays
 Hungry forever, consuming more stars
 As its gravity grows, it can move galaxies whole
 One day this black hole
 It ate one like it and it got supermassive
 It exploded and spit out hot space rocks and gas 
 Spinning so fast
 Forming new planets close and afar
 After billions of years all of these circled it
 Forming a pinwheel
 Which we call our home
 The Milky Way Galaxy
 Goes around this black hole
