Question About Atlantis' Shield

[Mister Oragahn]

Its not a mountain, its what a few hundred foot high max? A kiloton nuke would have leveled that mound of dirt if it didn't have a shield, are you suggesting SG weapons in general are so weak that they can't even compare to weapons we had in the 1940's despite being spacefaring for thousands of years.

The fact the first hit did nothing suggests there was a shield, even if the beam was particularly weak there's unlikely to be some sort of delayed reaction we'd see some sort of effect.

The fact that Ori beams did build up before starting blasting rock, just like the same beams build up against shields and then going through, pretty much says there was a force field of some kind, although it obviously didn't react (fizzle) and reveal itself to the naked eye.

Also, I don't think the Ori weapons are known for their sheer power. Really, I'd rather them in the gigajoule range, which is more than enough to level any skyscrapper.
They simply dig through armoured hulls, regardless of naqahdah, trinium, neutrocrap and stuff, via technobabble. Think of Lantean squid juice: it's pressed, compressed into a beam and fired at a target. It's like, err... a drone in the form of a beam of particles, okay?

It doesn't even need to be worth kilotons. Drones are best rated at two digits gigajoules, but can dig through Wraith armour that is known to offer more than decent protection against, at the very least, multi-megaton level nukes (which may even be shaped since 26 MT shaped nukes were used in Pegasus Project).

If you look at:

http://www.merzo.net/

Which is generally considered pretty accurate in its size estimations.

Hataks are listed as 1Km which is hardly a mountain. They also probably contain all sorts of volatile components etc.

I don't know where Merzo got his 1 km Ha'tak but I've never seen any evidence for that.
The proper numbers always flew between 600 and 700 meter wide, more or less a few meters if you used the distance between the most distant edges of the black part of the superstructure, or if you measured the length in the traditional way (which would be the good way to go, but the length would be slightly shorter than the "diameter" of said black structure).

It could have taken a large number of hits considering Bra'tak and Landry had enough time to move from the chamber to the gate and the Ori were firing continuously for that time. There had to be a shield. Also considering this is a multi million year old structure possibly not even protected by the best of Ancient shields and its an incredible feat!

Yes, many people forget that the beams we see hit are not the first to have stroke the structures. That said, I think we also see one or two beams hitting next to the temple, so it's hard to tell.

somebody calculated it to cost 10^28 joules.

Wasn't it calculated in that ZPM vs Neutrino Ion Generator (NIG) thread?

nothing. the asgard shattered, no, BLEW UP a planet in "Unending". takes 10^33 joules. probably even more, since the explosion wasn't neatly from the core but from the surface.

That and the expansion of the debris was particularly fast.
For example, on Curtis Saxton's website page about the Death Star's superlaser power, he pegs the expansion of Alderaan planetary mass at something e38 J in total.
Although I totally disaprove his dismissal of all the details that show the reaction to be exotic and not raw, the fact that the energy is indeed present.
The destruction of Orilla was just as violent, and in fact much more, since contrary to the demise of Alderaan, which in the book "Death Star" is described as partially being caused by part of the planet's mass being messed with via some "lightspeed" (hyperspace) reaction, the destruction of Orilla appears to be the pure result of a release of raw energy (following several surface explosions that would have no problem to be rated in the petatons).

clearly the asgard have the power capability. i already explained eons ago that it makes no sense for the asgard to have city ships. the city ship is more or less unique. but the Oddy in AOT takes more hits than Dakara.

Wait. Didn't the Odissey have like the naqahdah core, plus the Asgard power core as its main source?
Did it have a ZPM in the flick?

The Oddysey in Unending probably took less hits than Dakara though, in AOT the Odyssesy had Replicators onboard. Not only that but it had an ANCIENT powersource. Regardless Dakara is millions of years old was in the process of firing a proper Ancient shield would be significantly stronger.

It was powered by a zpm in unending too, so it was probably the replicators.

agreed - the dakara weapon was their before atlantis and they would have sure made sure (no pun intended) that no one could wipe them out with their own weapon (the cityshield might also stop the dakara weapon))
