I don't really see the 4th dimension as time. For a 2d being, time may appear to be the 3rd dimension. We move around in 3d so we can figure out pretty quickly that the 3rd isn't time, so we pushed that to the 4th.

^4th spatial dimension
Again, this is a misapplication of geometry. Simply claiming that time is a dimension does not make it one, and even if it were a dimension there is no reason to expect that it would be compatible with spacial geometry and the mathematical operations supported by spacial geometry.
You assume that logic that applies in this universe in 3d terms would apply in other universes or from other-dimensional perspectives. There is no reason to think this would be the case. You're just guessing.
No. We begin with logic, that is the tool you are using to reason in order to make your argument. If your argument concludes that logic is invalid or is only valid relative to this small slice of reality then your argument is self contradictory. You must assume the universal validity of logic in order to pose a logical argument.
There is an 11th dimension basically because the math requires it.
Mathematics requires nothing. Mathematics is a logic tool derived from physical reality for the purposes or predicting and assessing reality.
Empirical reality first, math second.
Read up on how the string theory people found that adding an 11th dimension unified the 5 different theories they had to a single... thing. The super gravity and string theory people both found that there were indeed 11 and not 10. This 11th dimension would be outside of the first 10 and allow for a new perspective, one that looks "down" on the rest of the omniverse.
This isn't science. If you want to postulate 99.9999999999999999999% of what exists we can't see, touch, smell, taste or hear then be my guest. But that isn't empirical and it isn't science. And, worse, it's not based on anything empirical. It's a bunch of misapplied mathamatical models layered one on top of eachother.
What this perspective would show is TRUE existence, a timeless, infinite portrayal of everything that can EVER possibly be imagined. If you don't want me to call it the god perspective then make up some other term, but that's basically what this would be, no? Nothing would even really ever happen from this perspective. I don't really understand how you can see an infinite number of occurrences as a single object either, but whatever.
It's just a stupid mathematical equation.
To illustrate, let's be highschool physicists for a minute. Our task is to measure this phenomenon which occurs in a jar. We measure the amplitude, and the frequency and the duration, the energy given off, the change in chemical properties in the substance in the jar. We take all these great measurements, and we put the data together and we abstract out a mathematical model.
This mathematical model is a formula we can use to predict the outcome of similar experiments without doing those experiments. This is what a mathematical model is for.
But wait, here comes an astrophysicist, and do you know what he wants to do? He wants to misapply our model! Instead of having it apply to the chemicals we were using in the jar, he wants to apply it to SOUND, or something equally ridiculous. And instead of using the model's variables within the ranges that they are valid for, he wants to feed in NEGATIVE time, and INFINITE heat energy. And he's going to sit there and manipulate and mutilate our innocent little mathematical formula until he invents A GREY HOLE; A completely new hypothetical entity, for which there is no evidence other than 'the math' and about which he is going to write a paper and secure funding and research grants and media coverage and all that good stuff.
So he writes his paper on grey holes, explaining that the math fits perfectly if you have an infinite concentration of heat energy in negative time using chemicals which haven't yet been discovered, and the grey-hole theory fan club clap and cheer and wave and all is well in the world of pseudo-religious mathematical bullshit.
Now, at some point, a REAL scientist is going to come along and point out what a load of garbage all this mathematical butchery is. And do you know what will happen to him? "CLIMATE CHANGE DENIER" "9/11 CONSPIRACY THEORIST" "CRACKPOT" A modern day witch hunt.
Do you think the above is absurd?
Dark matter?
Dark energy?
Black holes?
Neutron stars?
The big bang?
10 dimensional space?
Where's your evidence? It's all misapplied mathamatics.
