The Real Mother of All Bombs, 46 Years Ago
vaporland writes "Tsar Bomba is the Western name for the RDS-220, the largest, most powerful weapon ever detonated. The bomb was tested on October 30, 1961, in an archipelago in the Arctic Sea. Developed by the Soviet Union, the bomb had a yield of about 50 megatons. Its detonation released energy equivalent to approximately 1% of the power output of the Sun for 39 nanoseconds of its detonation. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout. The Tsar Bomba qualifies as the single most powerful device ever utilized throughout the history of humanity."
Trust the Computer. The Computer is your friend.
Because the statement that it would be equivalent to "The power output of the Sun for .39 nanoseconds" is misleading.
Don't get distracted by the 39ns figure. Power is an instantaneous quantity - it is a rate at which energy is transmitted. They are saying that the bomb sustained a level of power (rate of energy) output and held it there for a period of time - 39 ns - that approached 1% of the sun.
I repeat: 39ns is just the period of time that the power level peaked for. They calculated that the amplitude of the power peak itself, was equivalent to 1% the power output of the sun.
We don't care about how long the peak lasted for, the 39ns, unless you start integrating power over time as you just did, in which case you're comparing a quantity of energy, rather than a rate of energy output. Yes, I suppose you could say that 39ns @ 1% sun power is equivalent to an amount of energy produced by the sun in 0.39ns, but that's not the interesting number here, because we could similarly integrate just about any huge power source over a long enough interval of time (hours, days, years, whatever) to come up with "the same amount of energy output by the sun over 39 ns".
So the interesting number is in this case, yes, that the actual instantaneous absolute power output of the bomb approached 1% of that of the sun, albeit for only 39 ns.
Quite remarkable...
They are testing new materials and designs of the electronics and radioactive materials used. Some tests do fail or exceed expectations. Something like the George" shot, was physics experiment relating to the hydrogen bomb.
Buster-Jangle-Able was a fizzile with a one kilogram yield, but with alot of radiation.
The American test, Castle Bravo, yielded almost double the expected yield.
Castle Bravo didn't use cryogenic boosters for its fusion phase, so it lead to the developable and miniaturization of the hydrogen bomb (Fission-Fusion and Fission-Fusion-Fusion)
Then you tested to make sure entire systems world, like Grable of the Upshot-Knothole test was a nuclear weapon fired from a 280mm artillery piece and became the proof shot for the entire like of American nuclear artillery rounds.
Then also from tests at different altitudes they've learned to optimize the device's explosion altitude so smaller devices can be deployed.
