what are those white dots that you see in the first second of a nuclear fireball?

same effect here at the beginning

Mini nuclear lava bombs iirc

That is beautiful and terrifying.

Inital reaction is a large scale fission event of the desired atomic elements, these smaller 'micro detonations' are simply particles that had not undergone fission/fusion.
Brayden Garcia
now imagine that 3x bigger and you've got the Tsar Bomba, roughly equivalent in power to the energy output of the tunguska event.
humans have amde some scary fucking shit.
To answer the OP, I think they might be pockets of ignited air from uneven bursts of high energy photons and other forms of radiation from slight imperfections in the payload or its activation mechanism.
Juan Long
do you know which bomb that was? bravo.webm bomb?
Nathaniel Clark
From the name I'd think it was Castle Bravo, which was the largest nuclear weapon ever detonated by the United States.

Why do nuclear bombs produce a huge pressure wave? Doesn't the reaction just r turn matter into heat/radiation? Is it the expansion of the surrounding air that heats up quickly?
Nicholas Adams
Yes
William Johnson
the fissile material in the center of a nuke is surrounded by whats called a tamper, a layer of very dense material (usually uranium 238) that holds the core together for as long as possible to allow for the maximum amount of fission to take place before the core explodes apart. for a very short moment you essentially have the energy of a million tons of TNT compressed into an area the size of your fist. that energy wants to go somewhere, so it breaks through the tamper and creates a massive shockwave.
the tsar bomba was detonated in the air though, the yield was 3x bigger but the size of the explosion itself was actually pretty close to the castle bravo event. double the yield doesn't mean twice the size.

Now imagine an asteroid impact.

It's fascinating to a layman how the fireball can be roughly completely spherical yet the fuel burning is itself far from perfect in distribution. The force of the initial (main) reaction must be much greater than the rest of the burnoff.
Wyatt Ortiz
It's a relation of the Rope Trick effect.

Second paragraph gives some detail.
Asher Lopez
So it's the effect applying to shrapnel from the shell of the weapon?

>So it's the effect applying to shrapnel from the shell of the weapon?
I'm not sure the concept of shrapnel applies to atomized plasma, but yeah, pretty much.
Gavin Wilson
>mfw the tsar bomba blew out glass windows in finland more than 800 miles (1000 km) away from ground zero
based russians, no fucks given
Alexander Flores
uneven distribution of surrounding matter which gets heated up at different speeds therefore having different light emissions.
Lincoln Watson
>yfw the soviets used nukes to make artificial lakes
Jack Ward
I'm sure this is a dumb question but why do nukes explode so "slowly"? Like they're happening in slow motion. Something like a normal bomb or a grenade rapidly expands
Juan Price
Same speed, just instead of a grenade blowing up and flinging shrapnel across a few m^2 it's km^2. I assure you, i've tested both at close distances and both blow up just as fast.
Jordan Phillips
Ah cool. I wasn't thinking about scale like that
Andrew Campbell
One of the big things on my bucket list is to watch a nuclear detonation, preferably 5mt or greater.
Sucks that the us stopped testing and all tests now have to be underground or some shit
Wyatt Murphy
>I'm sure this is a dumb question but why do nukes explode so "slowly"? Like they're happening in slow motion. Something like a normal bomb or a grenade rapidly expands
They don't. Most nuke clips are high speed footage. The Upshot Knothole Grable shot (15kt) is one of the few that's regularly shown at regular speed.
youtube.com
Ignore the sound effects, because they're worthless and wrong.
Ethan Stewart
This.
Easton Mitchell
Would be brutal but realistic though
Camden Nelson
Yes, but the comment was in jest.
Jonathan Walker
they don't, it's either because the camera footage is slowed down or because the fireball is so big that its hard to tell scale. for example this explosion looks like it's going in slow motion but the fireball is actually expanding at hundreds of meters per seconds, the fireball is really fucking massive (more than 7km i believe).
Jacob Ross
Are there any videos that show timelapses of the smoke plumes of nuclear explosions over the course of several hours?
I'm curious to see how long the smoke plumes stay in the air and what they look like after, maybe, 12+ hours or so.
Justin Hernandez
nah, too symmetrical
Isaiah Price
the cloud basically just rises as high as possible after which it will flatten and turn into a regular looking cloud. this happens pretty quick in the span of 1-2 hours.
John Rogers
What happens to that cloud? Does it just disperse into the atmosphere? Could the cloud be absorbed by a tropical depression which later becomes a typhoon and makes landfall?
