A team led by NNSA a subsurface chemical explosion at the Nevada National Security Site to improve the United States’ ability to detect low-yield nuclear explosions around the world.
Thanks, found other article with bit more info on US and Russia.
Will post aswell, https://www.newsweek.com/nuclear-weapons-test-nevada-russia-green-light-1836394
Where are you seeing that the US conducted a nuclear test? The article only mentions a chemical explosion
Would you like to explain to the class what an explosion of chemicals and radioisotopes is? It's a clear retaliation for Russia pulling out of CTBT.
Sure, it’s conventional explosive with radioactive markers to test the detection capabilities of their equipment. I was being polite with my earlier comment, in case I had missed something in the article, but I guess I didn’t.
The Wikipedia page on Explosives gives some reading on the differences between the two. Suffice it to say, chemical and nuclear explosions are fundamentally different things; breaking/reforming of molecular bonds to produce heat and energy, compared to splitting or fusing atoms themselves, which releases FAR more energy than those molecular reactions since the bonds holding atomic nuclei together are so much stronger. If we say that a nuclear explosion is literally any explosion + radioisotopes, then you could buy some uranium online, tape it to a brick of plastic explosive, and say you’ve got yourself a nuke. Maybe someone should tell Iran they don’t need to waste all that money on centrifuges.
You’re half right though, in that this probably is a response to Russia, but demonstrating your ability to detect underground nuclear tests is not at all the same thing as actually conducting one.
First nuclear test inside the United States is NOT World News. The reason I didn't outright just delete the post is because it appears to have been done as a reaction to Russian policy. That's the tenuous World News angle.
