Do you think time is actually the 4th dimension or is it really a real 4D world? I can't see how time (something man has made up to keep track of the days) can be a dimension. There isn’t any physical property to time. And if time was the 4th dimension then would we say we could see 4D too?
Check this site out on if 4D was a real dimension not time.

I find this really interesting stuff… I just like picturing it in my head of what it would look like.
What your opinions on this?
