Survive is probably the wrong word, as they would obviously survive. But everything would be completely different, and nullsec would have to change alot to accomidate. Highsec is the economic and industrial heart of EvE. Even though alot of nullsec players have nothing but distain for the players that have chosen to live there, they cannot deny how important it is for them, and how much they rely upon Empire to sell and buy their goods.

Yep. Probably the best way highsec could embargo null without a fleet of tens of thousands, would be to have a bunch of people suicide ganking freighters in Jita for a few days. That would have a serious effect on the supply of goods to null. I think if the OP organized something like that, null would stand up and take notice.

There are player and NPC stations in nullsec. Nullsec is independent of highsec, and highsec is independent of nullsec.

Um..not even close.
If null sec disappeared, T2 production would be shred of what it is today. given the percentage of R32 and R62 moons in low sec, compared to null sec.

If high sec was wiped out (which happens more with every release), null sec would maintain their massive income, but the players would be bored out of their minds, as there would be no one left to grief, because many null sec players will shoot back, or rather, have game mechanics that allows them to shoot back.

Oh right, was that the t2 guns guy? That would explain a lot.

theoretically could null sec players survive if access to low/high sec were severed?

I suspect that they could survive at least either through POS production (assuming that blueprints are around) and fleet mining and internal trading. But the massive profits enjoyed by null sec corps would be gone along with the large scale wars that these empires funded. In fact pretty much all conflict would die of in null sec as the resource cost of ships have massively increased, especially tech 2 items due to the research requirements since those blueprints you need for tech 2 versions are now irreplaceable.

Meanwhile in high sec there are swings and roundabounts. At first the market would crash a bit as the flow of null resources stop and prices of ships rise. But on the other hand the demand for ships to fight the null sec wars decline so after a while the market would return to some form of stability. The main place where this isn't true however would be in mercoxit which would completely cripple tech 2 high sec production.

So in other words on both areas of space the tech 2 industry is crippled.

Edit: And before anyone says all mercoxit comes from sleeper. Shh. We're talking economic systems here.

Also what kind of fleet would you need to completely blockade all entrances to null sec perfectly 24/7?

Assuming you magically cut off all connection between Empire and Null (since Null and Highsec would leave the question of Lowsec, I chose to group HS and LS together as Empire space):

Empire would lose all tech2 stuff, since you need Nullsec material for them. Supply of material would be reduced (no more stuff being brought in from Null to be sold at Jita), but so would demand (no more Nullsec people buying supllies to jump freighter to null). Empire would survive, but you wouldn't see anybody flying tech 2 stuff anymore, and the economy would be much worse off.

Nullsec doesn't in theory lose anything, as they have all the same resources as Empire, plus tech2 materials. However, in practice Null is a lot more reliant on Empire than might appear. For starters, nobody does large scale industry in null. There are far less stations, and BP research slots in particular are in short supply. POSs can be used to replace stations, but are far more inefficient.
Nullsec could still produce any ship in game (except Empire faction ships, the BPCs of which are only availeable in Empire), but due to limited amount of stations and less players than in Empire (not to mention many, if not most, of those players disdain the very idea of mining and industry) the supply would be smaller. This would have a lot bigger effect than people might think. Producing a large fleet worth of ships takes a very long time. As long as there is HS access this won't be a problem as the large amounts of ships being produced in HS means there is a constant supply. Cut that supply off and suddenly you can't lose a couple of hundred battleships on a weekly basis, at least not until you've built a sufficiently big industrial base to churn out a couple of hundred battleships every week.
This might actually increase Supercapital-based warfare as Supers, while time-consuming to build, are also extremely difficult to destroy so you don't need to worry about replacing them that often. I'm not very well-informed on the specific of supercapital warfare, tho, so I might be wrong on that.
Also since certain materials are unevenly distributed around Nullsec, with no Jita-like trade hub, getting those materials would be a lot harder. Smaller coalitions would be unable to produce many materials themselves, and would eighter have to trade with others or get by with things they can domestically produce. Even larger coalitions might have problems. Then there's the fact that skillbooks and BPs are of extremely limited supply in Null.

TL;DR: Null would survive, but massive fleet battles would become rarer due to smaller supply of ships, coalitions would have to use most of their moongoo and other materials to run their industry instead of padding their leaders wallets, and some trade between different Nullsec powers would likely have to be established.

Easy answer is yes.

Nullsec = SOV and NPC null. Anything like CONCORD office to turn in overlord drops, BPO's, etc. Those could easily be added to a given station in NPC null to make it 100% isolated.

Would it be good for the game? .. no, it would be disastrous.

in some ways yes, some ways no.

While it would be disastrous to the existing economy and to the player base. It would mean that the null sec empires would actually start running themselves like real empires. Setting up an economy both internally and externally and developing a stable interstellar community. In other words building a real fictional empire/civilisation, instead of the existing resource extraction back to high sec bare bones economy you have now.

But I will admit while this idea sounds interesting to look at an observe, I doubt the people who will have to build and mine rather than shoot stuff will find it fun.

You can't jump into highsec only out of it

if you gatecamp both the gates on the null sec entrance system. We might not be able to see a covert jump field but if we put up warp jammers all around the gate to pull you out of warp and then blow you apart before you've got to the gate.

If its a big enough camp we should have the dps.

Tell me more about how null empires are run. :allears:

i think you might be talking about warp bubbles but they can't be used in low sec.
jump freighters jump to a low sec station undock. then they warp to the high sec gate with 100% immunity from ganking with any sized fleet.
If u want to kill them u have to bump them away from a station undock, catch them in an unusual place or at a jump bridge or the most popular option...... kill them in high sec either via war dec or suicide ganking. I suspect you have spent very little time in low or null Mr OP.

fine yes I have no experience at jump drives so its all completely for nothing, odd no one has mentioned blockade runners yet?
