Flights in null sec and wormholes
In null sec there is no Concord and no sentry guns, the integrity of your pod depends entirely on you. Roughly, in null sec all the same as low sec, plus there are additional opportunities for those bad people who do not give you to just fly. The most important difference between the low sec and null sec is that in the latter there can be used mobile warp disruptors (aka bubles). The function of this device is to form a sphere of a few kilometers (depending on the type of the Buble), in which warping does not work. So that a ship can warp, it must first leave the Buble. In skilled hands bubles are a powerful weapon because they give an opportunity to impose a fight in tight spaces. Bubles can be put by special ships - the interdictors, equipped with a special launcher for launching Mobile Warp Disruptors. In addition, there are heavy interdictors - they can use the module Warp Disruption Field Generator which forms a buble around the ship. Beside this, the buble can be moved along with the heavy dictor, changing its position by the pilot's choice. However, the ship's speed is greatly reduced if it moves the buble.
Aside from preventing warping, Bubles do one more function - they attract the exit point after warping to themselves, if the warp line passes through the warp buble. Simply put, even if you warp some kilometers away from the destination point, you'll anyway land into the buble.
Due to this module, there is another kind of "ambush":
Camps at star gates.
When you fly in low sec, you usually you warp to 0 m from the gate, through which you want jump. Using Autopilot in low sec will not be considered as it is in no way recommended. Jumping to 0 m is safe because if they do not manage to bump you off (and they should not unless you are asleep), then after the first shot at you, you jump through, and the shooter doesn't - he or she cannot do so because of the aggro. So catching ships at the warp in area at gates doesn't really have prospects in low sec. However, in null sec the situation is different.
On the line between 2 star gates, at a distance from the gate (at 10-20 km) camnpers place a Buble. The camp stays around the Buble awaiting transiting ships. What happens next is the following - you jump in to a system and see that local is greater than zero (i.e. there are people on the local chat). Yeah, you think, there must an ambush in here, so you must pass quickly. So you align to the next gate on your route and jump to it at zero meters. When you exit the warping, you find that it is never 0m, and the gate is somewhere behind. It looks like you missed it. But actually it was designed so. The ships was dragged into the Buble, and if the camp is still in place - they gently beat the victim by the head and take everything of value (including the pod, because in null sec there is no penalty for pod killing).
To prevent this from happening you need to remember that - if there are other people on local, and you do not recognize their faces, then you should not jump to the next gate immediately. Jump to the nearest planet, turn on the onboard scanner and scan the next gate with a narrow beam. If the scanner sees Small / Med / Large Mobile Warp Disrupt Probes - it means they are waiting for you. If you only see 1 buble, which is also small, there is a chance that when you warp at 0 m to the gate, your way will not pass through the buble, and you will land at the desired zero meters. But if there are many Bubles, better don't risk. The smart always go the roundabout way ;)
