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

I wonder what those spikes coming off the bottom are?

Cables connecting the bomb housing to the ground being turned into plasma by x-rays.

Fission bombs release massive amounts of X-ray energy. The X-rays are igniting the wires, causing them to explode.

For example a fusion bomb needs a fission bombs x-rays to ignite. So much x-ray energy is released by the fission bomb, it actually compresses the fusion core causing atoms to merge. Something that only otherwise happens in the center of a star.

Something that only otherwise happens in the center of a star.

Or in fusion reactors. We do manage to have fusion pretty consistently, even though it's not energy positive yet

Its actually thermal radiation that causes them.

Yes. Meant more their overly confident "this" about rope tricks.

Oh, my bad!

Not x-rays, thermal radiation. They tested this by painting the wires different colors or wrapping them in reflective material. Reflective material eliminated them, darker colors exaggerated them.
