That's some pretty heavy theory there so will take me a while to digest but, thanks, it seems to be what I'm talking about. Hopefully it will allow me to understand the absence of 3D shadows. I'm trying to be really careful to not misinform anyone as that can be annoying for someone reading...

Thanks, that makes sense. So to create a 4D image you would need to stack 3D cross sections connected via the w axis. Is that right? Obviously we couldn't see it without 3D retinas but have I got the principal correct? Nosebleed...

Thanks for the replies though I'm even more confused now! Does 4D spacetime consist of 3 spatial dimensions + 1 of time? And does 4D space consist of 4 spatial dimensions? If so, I'm referring to a reality which has 5 dimensions: 4 of space and 1 of time. Isn't this what the Nasa satellite going...

Yo anyone, Could someone enlighten me as to why, if there is a 4th spatial dimension, we can't see 3D shadows of 4D objects? Lots of talented people built an amazing 3D shadow of a 4D object but I'm almost certain I've never seen one pop in and out of existence while on the way to the shops...

Please let me know if I'm talking s**t at any point. Only been reading about the 4th spatial dimenion in the last week. What an amazing concept. Often an analogy is used of a 3d object passing through a 2d plane. As it passes through it creates a 2d slice. These 2d slices can be used to...
