Sagittarius A-Star

Welcome to Atmosphere42 also known as Electromagnetic Radiation which is just a fancy science word for light, this is my science blog. I've loved space and science ever since I was a little kid so I decided to start a blog about it with my free time in college. 

I'm a first year student attending a university to double major in Biology and English. I'd love to become a high school teacher to teach both subjects. If you want to know more about myself just comment below! My first post is just an introduction about our galaxy. Don't wanna talk your ear off or anything so I'll keep it short.. Happy Reading! Feel free to ponder the existence and the meaning of your life while you scroll through my posts.

We revolve around the sun, so what does our sun orbit? Sagittarius A-Star. 

By the time it takes you to finish reading this sentence our entire solar system will have traveled 12,500 miles per hour around the supermassive black hole named Sagittarius A-Star in the center of the Milky Way Galaxy. One orbit takes 200 million years. 

Say the average person lives to be around 82 years. 
That's 4.1 x 10^-7% (or .00000041) ... a blink in the time of the orbit. 

Science can tell us that we are a blink in time. 
But hopefully some of us share the belief that humans are eternal. What makes you eternal?
