Dark Matter: What We Don’t Know
Okay, I know…weird way to start a post, right? Isn’t this blog supposed to teach science? How can we teach something we don’t know? This is actually one of the most important concepts in the realm of astrophysics, and even…

The First Nucleosynthesis
One minute after the Big Bang, all the protons, neutrons, and electrons that would ever exist had been produced. There were no atomic nuclei, though. No atoms. No materials as you and I know it — like wood, metal, or…

The Universe’s First Moments
Imagine a time before galaxies existed, before the first stars had been born, before the most basic building blocks of matter — atoms — had formed. This was mere moments after the Big Bang. No one understands how matter and…

How Were Atoms Discovered?
Welcome to my fourth “Science Answers” post! If you have a question, you can ask it in the comments here, or ask it in an email. Or find me on Facebook! Q: (1) How did scientists find elements in the first place?…

What is the Intercloud Medium?
Stars are like headlights in a fog bank that’s impossibly thick in some places, and so thin as to be transparent in others. Sometimes, we get lucky enough for starlight to light up the fog. Other times, stars shine straight…

The Proton-Proton Chain
Take a wild guess: how much energy do you think the sun generates? Think about it. It definitely generates enough energy to power a world. Humans depend on the photosynthesis of plants, which converts sunlight into energy. And that’s not…

The Battery of the Sun
Does this image look familiar? It should — these are soap bubbles. Okay, now you’re probably going to ask me how soap bubbles have anything to do with the battery of the sun. Well…you might be surprised to know that…

How Atoms Work
Have you ever seen something like this? I’m going to venture a wild guess and say you haven’t, since scientists have only recently been able to take this kind of image. I learned about it in my biology class this…

Types of Atoms
Does this look familiar? It might, or it might not. If it does, you might recognize it as the periodic table of the elements — more often known as simply the “periodic table.” It’s an ingenious way to organize elements…

The Building Blocks of the Universe
“The Building Blocks of the Universe.” When you put it that way, atoms sound less like a topic specifically for a chemistry class and more like something astronomers might discuss. They really are. I’ve got a fantastic reason to include…
