Distances in space is so great that it needs to be measured in how long it takes for light to travel to that location. Light travels around 299,792,458 m/s or about 671,000,000 mph.

The Cosmic Calendar

Posted on September 3, 2024 by Matthew Marcus

For me, one of the biggest challenges in studying astronomy is truly understanding the scale of space and time. When humans have walked the earth for hundreds of thousands of years, it is hard to recognize that our collective existence is a mere flash in the grand scheme of the universe’s 14-billion year life. Every […] Continue reading →
