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.

Why power generated through nuclear fusion will be the future, but not the present, solution to humanity’s energy needs.
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.

From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
A wild, compelling idea without a direct, practical test, the Multiverse is highly controversial. But its supporting pillars sure are stable.
The surface and atmosphere is colored by ferric oxides. Beneath a very thin layer, mere millimeters deep in places, it’s not red anymore.
The first supernova ever discovered through its X-rays has an enormously powerful engine at its core. It’s unlike anything ever seen.
Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn’t that violate…something?
