Is it possible that 4 - D world did not exist once?

Question

How is that possible. Specifaclly time.

4 -D is lenght, width, dept AND time.

I mean ask..how could time not exist?

Answer 1

basically what you are now stuck with is a "picture" of the universe. Without time nothing can advance so the universe would be stuck one way forever(which is hard to measure without time, but you see the point). Once the universe gained that extra dimension, the universe could now advance. If the universe didn't at one point have that fourth dimension, it would only be there for the smallest conceivable instant at the beginning of time(since nothing would move at all in this state of no-time).

Actually, the Universe is a string of universes without time, strung together with time. Each "frame" of the universe has the standard three dimensions, but no time to itself. Time advances as we "move forward" along the string of unverses and each time something moves a little bit(like the way a movie is divided into frames. Each frame is a picture with no movement, but once the frames start moving fast enough, there is movement.)

Answer 2

You seem to understand that time is a dimension on par with the other three. Why have you singled it out as something you cannot understand not existing? Explanations are generally posed to provide a reason for something's existence, not its nonexistence. Why would anything need a reason to *not* exist? Is it necessary to explain why there is not a dog scratching at your door right now?

If not for the Big Bang, there would be no universe. Notice I didn't say "no universe now", because "now" would be meaningless without time. You made a similar mistake when you said ".. did not exist once". "once" means "once upon a time", which has no meaning outside the 4-D world. All we can really say without falling into these semantic traps is that there is the 4-D space-time created by the BB and nothing can be said, given our state of knowledge, about anything else.

Answer 3

they 4 dimensions always coexisted. and technically they always existed since space and time are connected and time started a finite time in the past. so there was no before since there was no time. so there was never a time where dimensions did not exist.

either all of them exist or none of them. and if time didt exist then that period in time didnt exist.

Answer 4

if there was no 4-D world once the time wouldnt have advanced till now as the time stopped that time wouldnt have started and the future of that time(present) wouldnt have come

Answer 5

How could the dimensions be more in-depth than 3-D, explain the shape please. 2-Dimensionals have flat properties, and 3-D explains Dimensions explain anything that has open properties no matter what. So there is no such thing as 4-D.
