Nature. In an experiment.

Why is blight so far?

Like, it sounds so simple.

They had no idea.

But now the data's...

I find this not only refreshing, but at some level astounding.

Nature.

Welcome back to the nature podcast. This week, quantum superposition gets supersized.

And Trump 2.0, one year in.

I'm Benjamin Thompson.

And I'm Nick Petrich Howe.

Okay. I'm Benjamin Thompson and I'm Nick Petrich Howe. First up on the show, quantum physics gets big.

And by big, I mean about the size of a protein.

To explain, we first need to revisit that famous thought experiment of Schrodinger's cat.

In 1935, Austrian physicist Erwin Schrodinger highlighted the absurdity of some interpretations of quantum physics.

The theory says that, until you look at a quantum system, like an electron, it exists in a haze of possible physics. The theory says that, until you look at a quantum system like an electron,

it exists in a haze of possible positions. Only when measured, does this superposition disappear,

replaced with a single definite location. Weird, but kind of fine for an electron,

but what about something bigger, like a cat?

The thought experiment involved a setup where the outcome of a quantum process,

such as radioactive decay, decides the fate of a cat.

If the system stays isolated, the decay is in a superposition of both having happened and not happened.
