Welcome to the science of the universe!
This page is organized with fundamentals up top and more advanced topics farther down, much like a school course. I highly recommend reading from the top — everything will make a lot more sense.
If you’re looking for a dedicated section on just the fundamentals, my Fundamentals page is the place to go. On the other hand, if you feel ready for more advanced topics, then just click on over to this page!
I’m working through publishing posts on each of the topics below in order. Bear with me as I get everything written 🙂
To see posts on a topic, just click on that topic and a drop-down menu will open.
I hope you enjoy!
