So how does any of that differ from using a conventional bomb doped with radioactive material, exactly?
Specific decay chains that only happen during fission reactions, not during natural decay.
I've spent the past few hours casually watching nuclear test footage and it all seems to start after the explosion. Which I find suspicious. There's proof they were doing film editing with a car appearing behind a house.
I think I know what you mean. That's not Trinity, though, that's Apple 2 from Operation Teapot. The common footage is cut together of sequences when they were setting up the test houses and then from actual test footage. You can also see how the lighting/exposure changes drastically, from clear skies being visible to the sky being pitch black. The flash is extremely intense and the fireball remains very bright for quite a bit, so the cameras have to run very low exposure.
So a bomb even more powerful than the ones that hit Japan didn't damage the wooden buildings half as much?
Trinity didn't have any test houses. Again, those famous video segments of houses being blown apart were from Operation Teapot in 1955.
And the surviving houses were like 3km away from Ground Zero (with Apple 2 detonated around 150 m above ground).
Nuclear radioactivity doesn't preclude nuclear weapons being real.
It's not just radioactivity, it's chain reactions, neutron cross sections, decay chains, mass defect. There's a shitload of nuclear physics in there that is not secret at all that feeds both nuclear reactors and nuclear bombs, and if nuclear bombs don't work, then nuclear reactors don't, either.
Thermobaric weapons have been known and used since World War 1.
Not on that scale, see below. Also, pretty sure proper thermobaric weapons came to be after WWII.
Hey look you contradict yourself.
Not a contradiction. The same principles apply, it's the same nuclear physics, but nuclear reactors use a different spectrum of it than nuclear bombs because you want to control the reaction, while in a nuclear bomb you want as much material to go through the chain reaction as possible. It's still all about neutron budget and cross sections and reaction chains, reactors and bombs just use different spectra. Delayed neutrons in a reactor, prompt neutrons in a bomb. Moderated/thermal neutrons in most reactors, fast neutrons in a bomb. Low enriched uranium in a reactor, highly enriched plutonium in a bomb. It's like, dunno, an LED lamp and a computer chip. They work on fundamentally the same semiconductor physics, but the details and applications are quite different.
Or they just lied, who was there to know?
The effects of the shockwave were measured all over the world, the glare was visible in Alaska, and the overall size of the mushroom cloud and ionising effects were just too large to be anything but an absolutely massive thermonuclear bomb.
Speaking of glare and clouds, you could see those from the Nevada test site in Las Vegas. They actually made it a tourist spectacle.
Why would you need to fake a pile of explosives?
I meant that you can't create an explosion of that scale without nuclear energy. The largest conventional explosion on record is the Halifax Eplosion with around 2.9 kt TNT equivalent. That's in the range of some tactical nukes and even suitcase nukes. Trinity was nearly 20 times as large. Tsar Bomba, at 50 Mt, was like 15000 times as big. The big pile of explosives you saw in the pre-Trinity test footage, that's 100 t. The Halifax Explosion took a big-ass freighter full of ammunition. And while any large explosion will create a mushroom cloud, no conventional explosion can replicate the very distinct and significant flash of a nuclear weapon.
Seems like you are trying to convince yourself more than anything.
I don't disbelieve in them but I find how lacking everything is when you start with the attitude "prove it to me". Look at how self referential all of your explanations are.
Nah, by gut feeling I'd say the official numbers are true, but I wouldn't be surprised if they're exaggarated at this point in time.
As for "self-referential", I don't know what to tell you. Nuclear physics involves a lot of indirect measurements due to the nature of what you're trying to measure (for example: neutron flux in a reactor core. It's actually quite complicated to get a good 3D reading throughout the reactor, and one method currently employed in EPR type reactors uses nickel balls slowly going through tubes through the reactor, and measuring their neutron activation, because it's actually surprisingly hard to measure neutrons [because, well, they're electrically neutral, so all the usual fancy ionisation tubes and shit don't work that well]), and it's all quite complicated in terms of safety as well. Measuring nuclear weapons is worse, because those fuckers are quite destructive to any measurement equipment close enough for good data acquisition. It's kinda in their nature.
