This is a picture of the first moments of a nuclear explosion taken in 1952. The blast radius at this moment is less than 20 meters wide.

There are so many extraordinary things about this photo. First off the fact that they had a camera in the 1950's capable of such insanely high speed frame rates (they created a movie from this) that it was capable of 1,000,000 frames per second. In many ways that is more impressive than the nuclear bomb itself.

Second the fact that you can see, in real time, a nuclear explosion as it happens. Those spikes at the bottom are called the "rope trick effect" which is caused by the support cables inside or holding up the bomb. The light radiation is so intense it vaporizes anything nearby causing things to explode just from the intensity of the light itself (before radiation has any effect at all). So those spikes are literally just the support cables exploding in the extraordinarily bright light from the bomb.

@freemo @Science Reminds me of how military people let out the strength of the atomic bomb because they didn't know physics

@mian @Science @freemo
I remember being told I once that they set it off not knowing if they were going to destroy the ozone or not in the process.


There were rumors it might cause a chain reaction and blowup the whole earth. Scientists, at least the better ones, knew this wasnt true. But still it was a speculation at the time.

@freemo @lucifargundam @mian @Science this reminded me of the concerns people had that the Large Hadron Collider would create a black hole that would consume the Earth.


Yea it was very similar in the sense that no physicists really took it seriously other than a few fringe ideas and speculation. But it was enough to start a rumor and a bit of fear.

Selling your soul to Alphabet by paying/promoting for Amp and merging with the global botnet?

I'd hope for better- but currently unrealistic under current expectations for most web users/admins.
