What's this about twelve strands of DNA? That would actually be a reduction seeing as most people have 46 strands. What you mean is a normal person has 2 of each chromosome (except men who have X and Y sex chromosomes) and you don't know why this is .. Well, I can tell you, it's because you inherit one from your father and one from your mother.

Having twelve of each chromosome does not mean that you improve. All it means is that you get more copies of the same genes. There are many organisms out there (particularly plants) that have more than 12 versions of each chromosome and we don't see them travelling through space and time in anything but the normal way. Even if you only had one strand per chromosome, if you were a woman, you could still have all the genes of a normal person of your sex present. Male honey bees are haploid (having one set) while their sisters are diploid (two sets) but they're still functional bees.

There are humans who only have one sex chromosome (some women only have one X) and that works fine. There are also people who have extra sex chromosomes like XXX and that also works because the extra X chromosomes (there are then 2 extras) are silenced in a process where proteins pack the DNA of the extra strand so tightly that it's no longer accessible for reading by other nuclear proteins.

Extra chromosomes can also have detrimental effects, the most common being Down's Syndrome in which people get an extra copy of chromosome 21.

Anyways, 12 copies of each chromosome or even more would not be good in humans. Most animals (aside from some lizards, flatworms and other exceptions) seem to do better with pairs of chromosomes. Those who have more still don't have as many as 12. It could have part to do with the physical environment inside our cell nucleuses, DNA takes up space and stuffing more in there might mean need for larger cells with possibly more mutations and crossover events where bits of some chromosomes stick on to other chromosomes. It also would give us a tremendous amount of DNA which we frankly do not need because it'd just be copies of what we already had - why have 12 when you get by on 2. For a human being to work with 12 copies per strand, aside from other problems, the extra DNA would have to be silenced as I wrote further up, otherwise he or she would overexpress many genes which would likely be fatal in a multitude of ways.

What I'm saying is what you're writing is idiotic, also from a biology point of view

edit :

As others have pointed out, we already experience the 4th dimension which is generally regarded as time, but what is the 5th supposed to be?
