The moment you make a scientific theory, the only way to confirm it is if you put it into practice. Otherwise it's utterly pointless to make them in the first place. The R-system and the Eclipse Project were probably too huge to accomplish unless they would have had vast resources, but it's rather unlikely that Zeref wouldn't have preformed any kind of other experiments at all to test his theories. He has made an entire army of demons, so he definitely did preform experiments at one point. The only point you make is that it wasn't shown he was doing experiments at that exact time. However the fact that the had been researching since he was a child, it's more unlikely that he didn't preform them rather than that he did. Especially because Zeref had the strong intention to bring Natsu back to life. He definitely did not formulated those theories to not use them.
Frankly the more correct questions here would be why would you think it was a factual god? Normally if someone would be cursed, you would expect some dramatic vision or dream where the god in question clearly states why he curses someone. Now it just popped out of nowhere. The only thing you actually have is that old man saying it's a curse. Zeref himself in fact questioned that as he said at one point "that I do seem cursed by the gods", which implies that he isn't even sure of it himself. At this point this gives the impression to me that this god has a notebook stating "Afternoon appointment: curse Zeref" and then he flips a switch to do it and forgets about it.
The moment the curse was first released, was on a moment Zeref just received a psychological blow. I mean why would a god have given him that curse on that exact time? But if you assume that it's the result of an experiment, which is very likely he preformed, it's possible that he was contaminated and that the psychological shock triggered a magical reaction. This on its turn explains what happened to Mavis. In the least Zeref believes Mavis has the same curse as him, but why would that god curse her too? He didn't do anything about Jellal and the R-project. He didn't do anything about the ones involved in the Eclipse-project, but he does curse Mavis for trying to save a town? The only thing that connects Mavis' condition with Zeref's, is that she used an incomplete magic she learned from him. If you assume that Zeref got infected by a failed experiment, it's possible that Mavis likewise became infected via the incomplete magic.
If Zeref really got cursed by a god, that god needs to learn to curse people properly.
Yes for every scientific theory to be proven, there needs to be an relevant experiment needs to be performed to back up the theory. I knew that but I doubt Zeref did performed all the necessary experiments at that time eventhough it is not completely impossible.
If you look at the every post of mine, you would have noticed that at some point I said God Ankhseram exists and at some point I even questioned his existence. I do this with each and every assumption I made. When I look at something being happen, in the same way I look at the very same 'something' how it may not to happen. The example would be me saying Natsu is END and at the same time questioning how he can't be before it was revealed in the manga.
And Zeref didn't used either R-System or Eclipse Gate as far as what it is said and what it is shown in the manga so far. He just showed how one can create and activate both R-System and Eclipse Gate which were later used by Jellal and Royal Kingdom of Fiore. The reason why zeref created the demons that could kill him is because the requirements need to use the either R-System or Eclipse Gate aren't met at that point in time like you said but let us not forget in the meantime Zeref is building up his Albareth Empire. So, the possibility of using both R-System and Eclipse Gate is not far from off. But Zeref attempted to create demons that have the power to kill him and succeeded in that experiment. It implies more that Zeref didn't attempt to perform any of the Eclipse Gate or R-system as if he did, he would have his little brother safe and good unless the experiment went wrong for a Genius like Zeref. See that I said all the possibilities.
Ofcourse Zeref himself questioned that did he perhaps got cursed by god literally 400 years ago. I myself brought that point in my previous posts. But in chapter 445,
You must be registered for see links
. There Zeref is certain about Ankhseram but whether he mentioning about his curse or the entity itself is what we have yet to know. You made this point of
"he made an entire army, so he definitely did perform experiments at some point." but why you not look at that this way like 'Zeref made an entire army of demons capable of killing him because he didn't performed those theorized experiments of him. If he would have performed those experiments then he would have brought his brother back to life which says him there is no need to go for END but Zeref went and Revived Natsu through 'ether'. What does this says?. Simply a reverse of what you are saying. Ofcourse both are possible given this is how Mashima writes the story.
@ What you said in the third para......It is another Possibility and there is an indication of that in manga too. Zeref's Curse activated the moment when he heard the shocking news of being expelled from the magical academy. That makes sense and I agree with that. Mavis has no references to Ankhseram whatsoever unlike how it was shown in case with Zeref. It wasn't specifically said that Ankhseram might be the one who cursed Mavis unlike in Zeref's case. So it is more likely that she received that curse due to the effect of 'incomplete law' Zeref taught her like you said.
Incompetent god... tsc tsc.
ahahah!
Well, I don't think it was a literal god. I mean, they refer to the top of the 10 wizards saints as the Gods of something. Don't remember the name. God is nothing more than a name.
In this case, I think they simply labeled something powerful, unexplainable and dark as a Curse from God. I still think that it wasn't, in Zeref's case, a direct result of using a certain Magic. But thats my own unproven theory. I feel that Zeref simply had a hidden power which he himself could not control or understand that awakened at that time of distress. I wouldn't be surprised if Zeref's obcession with bringing Natsu back would be fueled by him having killed Natsu early as childs due to that same unknown and hidden power.
And FH will be a spell that changes reality. you'll see!!!! I have spoken!!!!!
lol incompetent God.
They are not Gods of Ishgal, the official translation for that title is "Four Emperors of Ishgal"(大陸 (イシュガル)の四天王), there is no use of word God. The only one who as 'God' before their name is 'Serena' who seems to be suspicious and that is all.
Yes it seems like that and Let us not forget about the Yakuma Eighteen Battle Gods who are also referred to as Gods of Battle. I agree it is more like an exaggeration sometimes.
Reality?. That is a nice thought. By you mean altering the current reality in the FT or kinda something like that?.
Good discussions we are having this time. I think we almost covered all the major points here. Now in the similar flow, let us discuss about Ten Wizard Saints too.
1. God Serena
2. Hyberion
3. Wolfheim
4. Warrod
5. Juura
6. Not known
7. Not known
8. Not known
9. Not Known
10.Not known
Makarov has to be somewhere between 6 to 10. If we take into consideration that both Jose and Jellal(Seighart) will return to their positions as the Ten Wizard Saints in the manga, then it still leaves two empty spaces. So there are two more people we have yet to know whose identity is what?.
Who is Mermaid Heel's Master?.
