1. Does anyone have any suggestions on visualizing/perceiving 4D, or any of its properties, beyond mere 3D analogues?

---

I wish i could help, iv been trying figure out how to create
4d image on a computer useing the program language called visual basic and vector math with no success. I can only create 3d projections of the 4d object on the 2d screen.
That means the image is projection of a projection of the 4d object.
This problem gets worse when u try to express objects of increasing greater dimensions as projections on the 2d screen.
Maybe if i had a holographic projector i could do 4d projections in 3d but even with that a don't think the projector would be capable of creating a 4d image.
Not including time there's length, width and depth.
I just cant think what the fourth one would be with out resorting
to 3D analogues,all though iv been trying to for 15yrs

3. Is the concept of a spacetime (not ours; just hypothetically) with more than one temporal dimension possible? If so, what would be the properties of such a universe? What would life there be like? Could anything even exist in it or would causality fragment into chaos?

---

Like time moveing at differant rates in differant parts of the universe?
and or
Mabey time moveing backwards in one place and forwards somewhere else?

Visualization is not intrinsic to 3D. Imagine a Flatlander; he could only see a line in front of him. He would not be able to visualize 3D because he had never experienced it, nor could he ever consider shapes like circles or squares to be flat, since they have both width and depth. Similarly for us, we might not be able to imagine a 4th spatial dimension, but that does not make one impossible. I believe an intuitive grasp of higher spatial dimensions is only a matter of training

---

An interesting problem, he can look side to side and forward and back
but not up and down because that's not a possibility for him in his 2d world.
So the question i have to ask is this,
if i can look side to side and forward and back AND
up and down, what is that other direction to look
in that's not a possibility for me to perceive because i am a 3d lander.
