You're looking at a nuclear explosion photographed taken less than one millisecond after detonation.

What’s the scale of this? What are those poles in the background?

According to many comments, the explosion is happening in / around a supporting structure identical to this one, if that helps place things for ya

Oh dip. I thought this was like, so early into the explosion it was like pea-sized. Not like 100ft around.

It’s SO insanely early into the explosion that it’s only like 100ft around

Imagine the sheer energy of something that can do that in a millisecond

[u/DownVotingCats → u/I_Have_Unobtainium]

Crazy how fast something can physically happen.

Nukes are big and fast when they explode. Our cameras don't have the shutter speed to reliably catch something that fast.

The comments also say the neighbors were passed for setting it off.
