Space Reflection

I can never wrap my head around how large the universe is and how we are looking back in time while looking at the stars. The speed of light is 299,792,458 m/s or 671,000,000 mph. Since light travels so quickly, we don’t experience delays in everyday life. In comparison, the speed of sound is 343 m/s or 767mph. Think of the delay that happens between lightning and thunder. If a storm is far away, there will be a greater gap between the lightweight and the thunder we hear. If a storm is close, there is a small or even nonexistent gap. However, the universe is so huge that we are viewing what some stars looked like millions of years ago. A light-year is the distance light can travel in a year which is roughly equivalent to 6 trillion miles. Icarus (pictured below), the farthest individual star that was ever visible, is 9 billion light-years away from earth, which means when someone views the star, they are looking at how Icarus looked 9 billion years ago.

    I agree that it’s nearly impossible to wrap our heads around how big the universe truly is and the videos we watched in class really made me think more about that. Also I think the image of Icarus you found is so beautiful!
