#20: An Expanding Universe
The cool thing about science is that it’s always changing. Humans are always making new discoveries that expand our understanding of the universe. This is especially true when it comes to space exploration and physics. The information our society possesses about the universe has expanded from even a few years ago.
An astronomer shared how our understanding of the universe had changed from when she was a kid to now. Back when she was a kid, she learned that there were no other planets beyond our solar system. Today, we know that there are an infinite number of planets and stars out there that the human mind can’t even comprehend. Pretty cool. Who knows what we’ll discover in the next decade?
