Final Exam part 2 the earth in space

Our solar system is just a tiny speck in the Milky way galaxy, and the Milky way is just a tiny speck in the universe so on and so forth. Our solar system is a measly 28,000 thousand light years from the center of the universe.1 Our solar system is also 20 light years above the equilateral plane of the milky way.1 Our galaxy, the Milky way, is about 100,000 light years wide and we are about 28,000 light years away so our solar system is one of the closest systems to the middle of the milky way galaxy. The universe is one of the most unfathomable ideas to the human brain. the universe has never been accurately measured.  There theory's to the universe, like how the universe could still be growing,1 or that we can only really see 3 percent of the universe.1the structure of the universe is another story, the universe is supposidly started when the big bang occured billions of years ago.1 It created this mass of matter that fused and mixed with others to make galaxies and nebulae.1 the universe itself is like "primodial soup" of galaxies and  Nebulae.1 The last wondrous part of the universe is the age, before 1999 scientists had to guess the universes age but now the scientists of the world can date stars from all over the universe.1 Scientists have concluded that the universe is 13.7 billion years old, with a 200 million years missing here or there.1The big bang theory is a theory that 13.7 billion years ago our universe started as a black hole or sigularity and had a very small, really hot, infinitely dense mass that suddenly expanded and cooled to the size of the univese we have today.2 Which begs the question is our universe the only universe or could there possibly more. Cosmic Microwave background or CMB is a low level of energy released for the big bang when it happened.1 cosmic microwave backgrounds were released 380,000 years after the big bang these waves were visible to radio static and Astrophisists study them to help date the universe back to the big bang.1Once these lines used to be visible because the radiation amounts were so high from the big bang they slowly dispersed.2
