I know people would dis agree with me but my view of a 1-D entity is an Atom & Nucleus. Nucleus is the core of the atom and the size of the Nucleus to
an Atom is one red blood cell inside a Human. Thats how small it is.
I look at a 2-D being is a germ, cell or virus. They are intelligent beings though many would'nt look at it like that.
Red and white blood cells go after bad viruses and try to kill it. This is a form of intelligence, same with a virus. (Try not to flame I use my
imagination and these are just my views, I'm not trying to push it on anyone else)
Now I can't say for sure but I don't think cells/viruses have eyes to see what it's doing, so it only knows up and down left right and may not have
a concept of time.
So if your looking at a cell/germ/virus on a microscope, and the cell happened to have eye's and you place an object in front of it, say a pin, it
would only see a sliced view of the pin and then maybe try to touch it, then it notices it can climb up, so it climbs up the pin.
I like to think of this as a 2-D being living in 3-D space even thou it doesn't have any concept of 3-D.
When I think of a 4-D being, I like to think of an advanced alien life form.
I believe aliens are visiting Earth (we have a lot of UFO's in Toronto here)
Now the fastest thing us humans know about is light.
As far as science goes light is the fastest thing, which of course is not true.
For aliens/UFO's to get here in a timely manner, they have to be traveling much faster than the speed of light. Seeing as the closest star is 5 light
years away (and they most likely are not from that one star system) they would have to be traveling faster than that to get around effectively.
That means they must be using some kind of worm hole or holes that are short cuts to different parts of of space (I could be wrong of course), or they
are seeing things we can't see that are in 4-D (maybe energy lines, or maybe worm holes ARe on the the 4-D and we can't see them yet)
I personally think these aliens see things that we can't.
When you look into Super string theory, Dark matter and Dark energy, we start noticing galaxies with very strange shapes and supposedly star systems
with planets not shaped like our world (sphere), but in strange strings-like forms. Now if life are on theses planets they might not see their planet
as the string-form we see, but from there own perspective of course. ( you gotta do you own research on this, it gets complicated, I learned some of
this from www.teach12.com...
There are places in the universe that have things in them but are invisible to us, we are trying to find way to detect parts of the universe still of
Anyways take what I say with a grain of salt, I'm not claiming to be an expert but I like to use my imagination, and when we talk about things that
are not so well known, your educated guess is as good as anyone else guess, including scientists.
But we have reached far enough in math and science now to know that there are other realms and 4-D pretty much is real it can't be disproved.
You gotta keep an open mind, nothing is impossible, but for us time makes everything possible seeing as just about everything can be done as time goes
by and we advance.
