Is there any footage of a modern day nuclear test explosion?

Are they really? I did not know that.

All nuclear testing is banned in all environments.

US testing is done theoretically using supercomputer models now.

The modern weapons are exponentially more powerful than the 2 we dropped on Japan.

Way too damaging to test.

This is only making me want to see video of it even more

It's been that way for decades

Nuclear testing fricked up all the radio dating methods. Now we don't know how old the earth really is. So what. Who cares.

Check out the youtube footage of Tsar Bomba

The most powerful bomb ever was tested in the 50s, way more powerful than today's tactical nukes. Lol at this "too powerful to test" BS.

So far from the truth. The most powerful, latest nuke at the moment is not a tactical nuke.

You probably don't fully grasp the implications of that statement.

Nope. The U.S. signed but never ratified the Comprehensive Test Ban Treaty, so we're not bound by it. We did ratify the Limited Test Ban Treaty of 1963 which prohibits us from conducting atmospheric, aboveground, and underwater testing. We can go out into holes in the desert (also South Mississippi. Look it up.) and turn as much rock into radioactive glass as we wish as long as we do it far enough underground that it doesn't appreciably leak fission products.

We choose not to conduct underground testing even though we're not bound by treaty because 1) enriching nuclear material just to turn it into hot plasma in a test is fricking expensive, 2) We understand what's going on enough to work with simulations inside supercomputers for new designs, 3) seismic and electromagnetic signals from underground testing leak information about your weapons design to the rest of the world, 4) dealing with the sandworms is a goddamned hassle.

We still do set off warheads, though, for testing the design and readiness of the weapons. That's relatively cheap once you remove the cost of burning up your nuclear material. The warheads' nuclear cores are replaced with instrumented dummy cores. We know enough about the behavior of nuclear materials to predict the yield of the device (if a core were inserted) from the data measured by the dummy cores when the high explosive lenses are detonated.
