The Fourth Dimension: Introduction to a Book

[mysearch]

The Pauli exclusion principle is only with respect to time, so no, I do not believe it would violate it.

Fair point, but the argument seemingly being put forward in #18 was that “there is no such thing as time, only space”. Therefore, I was only highlighting that removing the concept of time has knock-on effects with respect to current science.

I'm not really sure what you mean, but I don't think you can maintain as clear a distinction between them as was previously thought by Newton etc. Clearly one affects the other, but I'd agree they aren't the same.

As far as I am aware, the main difference is that Newton saw time as an absolute concept, while Einstein describes time as a relative concept. Therefore, I was just questioning whether the concept of spacetime really affects our separate perception of space and time.

I don't believe the balloon analogy should be taken too far to apply to the shape of the Universe. I think it is only used to explain how Earth is not in the centre despite everything moving away from it.

I agree. However, to many it seems to infer some description of a boundless universe. Therefore, I was just curious to known whether there was any rationale behind this inference or that it was simply pushing the analogy too far.

But don't ask me, I'm only a 17 year old.

Unfortunately age isn’t always an indicator of intelligence or wisdom. If it were I would be a lot smarter.

I think there doesn't exist a four dimension. Although visual spatial learner can see with 3 dimension in their mind. so I guess what you call the fourth dimension is actually the 3 dimension but spatial. just like you have 3 d en ddd stands for 3 d such like windows vista and mac, the screen can turn itself, unlike the ddd that de picture can come out of the screen instead, and that create the spatial effect. I am a visual spatial learner, and see picture and movies in 3d en ddd (spatial) in my mind. I know exactely where is something wrong.

Dear Maxvan
Allright so you have a 3-D imagination and also some beginning technology on that area. I have some ideas how to make the fourth vivid.
1 A ship or a duck makes a fore in the water. It is adding up circles; and if the ship/duck bathe in this situation for a conciderable time then it tends to a V,
but what if the ship/duck just started?
2 An airplane drops parachutists. You see the first perhaps with open shute and others with a downgoing line ending in the open door of the plane.

are those four dimensional pictures or not?
