By: Jimena Lozano,Shelsy Hernandez
You might have wondered why the sky is blue.Or what gives sunsets there brillinat red.these bright colors stick out in the natural world and beg for an explanation.But have you ever wondered why the night sky is black?
The question barely makes sense the first time you hear it.''It's like asking why water is wet'',says Will Kinney,a cosmologist at the University at Buffalo, centuries the darkness of the night sky had astronomers and stumped. They called the puzzle Olber's Paradox.
"The fact that the stars are everywhere makes up for the fact that some of the stars are far away,'' says Katie Mack, an astrophysicist at North Carolina State University .No matter which way you look ,in an endless universe your line of sight would always end smack on the sun.
Probing the farthest and oldest parts of the universe usaully takes years of research and powerfull telescopes,but the night sky has been dangling the answer to one fundamental question right before our eyes the whole time .All you have to do is go and look at the spaces between the stars.
