You probably already know this, but not I've linked to this from SB, so he'll see it, he simply doesn't belive me, either his grasp of physics is either really really bad, or he's lying and knowing it.
Here's the argument he presented:

According to the ICS, the blasters on Slave-1 has a yield of 600 gigajoules or 0.14 kilotons per blast. I did some research to see what would happen if you set off a .14 kiloton explosion and find the Underground Testing at the Nevada Test Site. From Underground Testing at the Nevada Test Site:

Operation Whetstone
Test: Sulky
Time: 19:35 18 December 1964 (GMT)
Location: NTS Area 18d
Test Height and Type: Shaft, -27.1 m
Yield: 0.092 kt

This was the 11th Plowshare shot and was conducted by LLNL. Sulky was fired to explore cratering mechanics in hard, dry rock and to the study dispersal pattern of airborne radionuclides. Sulky was fired in granite strata overlaid with basalt. To the surprise of the test designers, who had expected a depression,it produced a permanent rubble mound called a "retarc" (an inverted crater - the word is "crater" spelled backwards). Permanent retarcs of this kind are restricted to hard rock where the shock displaced material, which has three times the volume of the original strata, is strong enough not to undergo compaction and subsidence. Strong rock like granite is especially conducive to this, since it tends to fracture in large blocks for maximum bulking effect. Sulky was in fact the only retarc producing event in the history of US nuclear testing. The mound was 24 m wide and 6 m high, and had a small depression in the center (9 x 3.5 m). Sulky released 13 kilocuries of I-131.
Here is a picture of the mound.

Now, let's look at Slave-1 in action:

As you can see, dispite have shots with a yield compariable to a tactical nuke being fired several times per seconds, the large asteroid is relatively intact. Now, had Slave-1 fired actual .1 kiloton blasts, we would have seen huge chunks being torned off the asteroid. The only reason why we don't see a crater at Sulky is because the bomb went off 23 meters underground. Otherwise, there would have been a 24 meter wide crater instead of a mound.

As further proof, take a look at this.

From http://nuketesting.enviroweb.org/he...sts/Nougat.html:

Danny Boy 18:15.00.12 5-Mar-62 NTS, Area 18 Subsurface -110 0.43 DOD/LRL WE Test of atomic demolition munition (ADM) cratering effects in basalt, crater 265' by 84', design yield 470 tons
The yield is equal to three blasts from Slave-1's cannons, according to ICS. Yet, this sort of damage wasn't witnessed in the dog fight between Obi Wan and Jango Fett (apart from the mines and missile fired by Jango Fett). Already, we can see a glaring contridiction between the ICS and the actual movie.

Dissect at your leisure, he ought to see it.

Damm that guy is stupid.

We can surmise his (flawed) argument in two words and a symbol

Code: Select all

Nukes = DET

Just a minor nitpic, but those guns that where being fired, where the one kiloton laser cannons. The blasters are the little rotating turret that fired at Obi-Wan

A wide, shallow rubble pile is not the same thing as a deep crater, a surface laser hit is not the same thing as a buried explosive, and if those asteroids were nickel-iron, they sure as hell weren't the same as basalt. Duh.

Wong: Damn you. I was about to point out how basalt and granite are nothing like nice hard NI asteroids then i scrolled down to your post. BAH.

Could you please explain to me how basalt and granite differs from Nickle/iron and how they will react and such?

Basalt is basically solidified volcanoic rock which break apart easily, Nickel/iron requires much heat too break up.

Is there anyway to guesstimate how that explosion would have looked like had not been basalt/granite but nickle/iron?

kojikun · Post by **kojikun** » 2003-01-05 08:45pm

i would think not exploded at all. that rubble heap is a few meters high, and its soft rock. with iron-nickle i highly doubt that anything more then a slight depression would be see.

The asteroid is 100 of meters away to.

Mostly though lasers packing .14 kt of energy are not the same as nukes packing .14 kt of energy.
