A small blue rock in the middle of nowhere, space
I'm a 19-year-old Physics major, interested in astrophysics. Thinking about becoming a cosmologist or stellar physicist in the future.
One thing to note is that comet-hunting used to be at least 50% of astronomy (back a couple hundred years ago). Now there might not be 50 people in the world who research comets.
From my astro classes:
It took the smartest brains our species has ever produced thousands of years to come up with our modern understanding of physics.
Star systems are like relationships. When only two bodies are involved, things work out pretty nicely. However, when you add in a third body, things get a lot more complicated and sometimes more fun.
