My recently started blog - need suggestions

[Picard]

I was talking about this:

"So Star Trek shields have 3 components - gravitational, electromagnetic and subspace."

[Mike DiCenso]

About "Chase", planet was not shielded, it was uninhabited and Bird of Prey actually used chain reacton. I watched episode recently due to some things I needed for blog - firepower and warp speeds, to be precise.

That wasn't Lucky point exactly. The ability to wipe out a planet's surface like that indicates that other planets would need shielding to protect themselves from that or more conventional means of attack.

What is meant by frequency is not clear in Star trek. It could mean a whole extremely wide range of things such a string theory, or it could be talking about something like alternating current.

Exactly, if you only cover a city or factor in Trek like they do in Star Wars the rest of the planet is toast, and the thing under the shield won't be there for lang either.

Theater shields might be good enough for archeological digs, but they would be pointless when it came to a planet like Trek Earth from an attack from other Trek powers.

Thanks for pointing that out.

That was already debated in the threads

• • Base Delta Zero
    
    • • • • and
    Alderaan, & problems with planetary shield claims

In the first

• • • • To be an effective protection, such a shield would have to have its perimeter beyound the atmosphere.

        • On the one hand, it would be necessary, when such shield would have to be activated over a long period [e.g. during a siege], to not disturb the dynamics of atmospheric processes. A shield, which has its perimeter only some kilometers above the surface of its planet, would cause serious disruptions in these.
        • On the other hand, when there is still atmoshpere beyond the shield, an attacker could simply use biological or chemical warfare to contaminate the atmosphere above the shield. These warfare would sink to the surface as soon as the shield is deactivated. A contamination of the exosphere, the uppermost layer of the atmosphere, would be enough, to achieve such a goal. Though, the exosphere is the only layer from the atmosphere, from that atmospheric gases, atoms, and molecules can, to any appreciable extent, escape into space, not all will escape and especially heavy chemical or biological molecules can sink to the surface of a planet from the exosphere.

        That's why a planetary shield, which should provide an effective protection, should have its perimeter above the exosphere, the uppermost layer of the atmosphere.
        
        On Earth, the upper boundary of the exosphere is at about 10,000 km above the Earth's surface. Therfore, the perimeter of the shield would have to form a sphere around an earthlike planet with a radius of circa 16'000 km [from geocentre to the surface (6'378 km) and from the surface to the upper boundary of the exosphere (10'000 km)]. That corresponds with an surface area of circa 3'521'058'974 km².
        
        To cover such an surface area with shield-generators, form which each single shield generator covers an surface area of circa 20'547'586 km², there are circa 171 shield generators necessary. A little bit more, than only 24 Endor shield generators and projectors.
        
        
        

        • • Even if someone would decide, that it isn't important, that the exosphere is protected by the planetary shield too - and that it is enough, when the planetary shield forms a sphere only 1'000 km above the surface of the planet, that would still be a sphere with a radius of circa 7'378 km [from geocentre to the surface (6'378 km) and from the surface to an altitude of 1'000 km], which corresponds with a surface area of circa 684'137'622 km², which would need 33 Endor shield generators.
            
            
            
            But it should also be noticed, that the 20'547'586 km² shield surface of the Endor Shield generator is probably far to high:
            • Wookieepedia gives an diameter for the Forest Moon of Endor of only 4'900 km. But the second DEATH STAR seems not to be a plametary diameter away from the surface of the forest moon.
              
              An altitude of 7'000 km is therfore out of question.
            • Furthermore, STARWARS.COM gives the second DEATH STAR an diameter of only 160 km and not 900 km. That meets the scaling [1], from Lucas independent persons have made, which are - as far as I know - not justified disproved.
            If someone know or can scale the real altitude of the second DEATH STAR above the forest moon, it would be possible, to calculate a more realistical performance of the Endor shield generator.

In the second thread, I quoted from the first thread and added this:

• • • • A shield beyound the atmosphere would be about that far away from the planet:
        
        The inner circle would be at an altitude of about 1'000 km and the outer circle at an altitude of about 10'000 km above ground.

About Death Star sizes, see here:

I did analysis and it is very near Darkstar's values - I used some screenshots from his page (I did not have movies on my computer back then) and my values are extremely close to his.

[Lucky]

Thanks for pointing that out.

Your welcome.

One thing to remember is the E-D was able to make a 3000 km tunnel with it's phasers in something like 20 seconds while being very care to do it in a controlled fashion. Barring the need to capture a base a trek power(United Federation of Planets, Klingon Empire, and likely most of the lesser powers) can easily tunnel under a theater shield.

Interesting;

In this shot, trench is 1 mm high, with DS being 187 mm high and 204 mm wide. Using previus values of 654.75 meters and 727.5 meters for one milimeter, we can get following values of either 122 438 or 136 042.5 meters for DSI height and either 133 569 meters or 148 410 meters for DSI width.

Your values sit between both EU's values for the DSI, without ever reaching either.

The trench of the DSII is more problematic. RSA has shown that the vertical surface above the superior edge of the visible trench is flat, but the pro-900 km argue that the flat surface is inside the super-trench.
It's true that on the picture of the trench we see in ROTJ, the lower rim is clearly larger than the higher rim, and not only that, but the panels that compose the "floor" and the "ceiling" aren't even lined in parallel, which gives the impression that one of the two rims is spinning in comparison to the other.

[Picard]

From what I can remember, DSII trench is similar in size to DSI trench. I hope I am not wrong - that would mean doing entire evaluation job for DSII from scratch and currently I don't have time for such endeavour.

Also, where is scene when ISD shoots asteroids while pursuing Falcon? Tell me scene right before and right after it.

EDIT: It is this scene, but unfortunately I can't say how exactly big was that asteroid from explosion (I can only guess and I don't like guessing if I don't have to beacouse it would give entire range of values).

That link does not work for me.

[Mike DiCenso]

The only scene with an ISD shooting asteroids occurs immediately after Luke learning who Yoda is, and is followed by a cutscene to several TIE bombers strafing the large asteroid the Falcon is hiding in. When the ISD Avenger chases the Falcon out of the asteroid field later on, it does not hit any of the handful of asteroids both ships pass close by. For years, Rabid Warsies have claimed that flack bursts are asteroids being hit, but they are wrong or lying, we only see flack bursts around the Falcon and nothing more. A similar situation occurs in AoTC with the Slave-I blaster bolts missing and creating flack bursts. When a couple of asteroids are hit, they shatter, and the debris flies away at only a few meters a second.

It is easy enough to scale the asteroids in that scene. The fourth and final TL shot can be traced back to the large trench notch and if you are willing to do some work, you can scale the TL bolt to the trench sidewall. Assuming the offical material's 1,600 meter length for an ISD is correct, that places the average height of the trench at 22 meters. You can then get a good estimate of the TL bolt's width not it's length since it is viewed at a roughly 3/4 angle. From there it is simply a matter of comparing the TL's width to the asteroid, and you should get an asteroid not less than 1.5 meters and no larger than 14 meters on it's long axis.

Thanks. I found it.
