The universe is out there, waiting for you to discover it.

Our mission: to answer, scientifically, the biggest questions of all.

  • What is our universe made of?
  • How did it become the way it is today?
  • Where did everything come from?
  • What is the ultimate fate of the cosmos?

For countless generations, these were questions without resolutions. Now, for the first time in history, we have scientific answers. Starts With A Bang, written by Dr. Ethan Siegel, brings these stories — of what we know and how we know it — directly to you.

It’s a strange idea to consider: that a tiny building block of matter, the atomic nucleus, holds the greatest potential for energy release.

And yet, it’s true; while electron transitions in atoms or molecules typically release energy on the order of ~1 electron-Volt, nuclear transitions between different configurations release energies a million times as great, on the order of ~1 Mega-electron-Volt.
