Why don't physicists explain things with a simple 4th spatial dimension?

Question

When they first came up with postclassical theories, the 4th Dimension had been discussed for decades and had degraded into a lot of wackiness. So Einstein and others were afraid to posit it.

Wouldn't 4D explain the quantum leap? To understand, reduce things to 3D: You're shuffling along the sidewalk in virtual 2D, but by lifting your foot and stepping into the 3D, you go from point A on the 2D sidewalk plane to point B without ever touching the line AB.

Also, gravity occurs when a particle sinks into 4D and, like a boomerang, collides at the dimensional interface with the object affected by the gravity and pushes it towards the other object.

Someone said that if Aristotle were brought to life today and informed of the historical progression of science, he would understand everything but postclassical physics. The logical conclusion from that is that such science is nonsense. But escapist freaks are childishly mesmerized by the glitter on Nobel prizes and intimidated by dogmatic paradigms.

Time has no extension, so it can't be a dimension. The quantum leap is impossible without a real 4th Dimension. Heisenberg, a Nazi, was too stupid to invent the atomic bomb, so his goofy Indeterminacy should be challenged as determined by an extradimensional force. Hiding from life by becoming a lab rat causes such psychological disorders and a faith in the irrational.

Answer 1

I assume that you are supposing some sort of conservation of objects in 4D. What other properties does this 4D world have? What laws does it obey? How do we test those laws? What do you mean by a 'dimensional interface'?

There really isn't any hesitancy to use more dimensions when such are needed. Kazula-Klein theories use them all the time. The problem isn't postulating the existence of another (or even more) dimension. The problem is figuring out how to describe the physics we actually see using these extra dimensions. Certainly, nobody has been able to come up with a theory like what you are proposing that allows anything like the accuracy of prediction already acheived by quantum mechanics. If you think you can do better, please do so. But it should be a fully mathematical treatment rather than some vague phrases about 'lifting your foot'.

Answer 2

The thing is that human beings have the mental capacity to be able to visualize only three of the total 11 dimensions... To explain something like quantum leap in a dimension that cannot be described or visualized is rather difficult to sat the least...

Answer 3

Technically, the 4th dimension is still just a theory. Its not really proven, although scientists believe in it.

Honestly, there is no real simple way to describe a 4th dimension. It might seem easy enough to add time to the 3 dimensions, but there is more to that. Most people are too dumb to understand (seriously)

Answer 4

when you add dimensions you make it easier to describe physics but you cant just keep adding dimensions the best theory i have heard still in my mind is superstring symetry which takes 10 and 26 dimensions depending on the spin. A fourth spatial dimension is already in theories, they have gone much past that point.

Answer 5

As if multiple dimensions weren't part of current theories in physics? Do you think you invented this? I've heard this many times before. You should start teaching physics so you can explain this to students. I did.

Answer 6

i have a feeling that the fourth dimension is time!

take a photo frame for instance. it has length, breadth, an height. so we call it as 3d. but living thing have age and memory too apart from these three. thus we can say we are sorta 4d.

Answer 7

By knowing the truth and attaining self-knowledge.

Unified theory is explained in this book.

http://www.amazon.com/gp/product/0791413640/qid=1152304319/sr=2-1/ref=pd_bbs_b_2_1/103-1016054-7543827?s=books&v=glance&n=283155

Read that ancient scripture. It talks everything about blackholes, time travel, particle-wave theory, aliens, consciousness, mind, matter, energy, creation, unified theory, psychology etc.

Everyone should read it atleast once in their lifetime.

I guarantee it will change your life. Those who don't read it or cannot access it and follow it are really unlucky. Salutations to them. Those who can read it and follow it are great. Salutations to them.

Answer 8

a layer of complication is not an explanation. You might just as well call it "The Magical Realm". A theory needs to be based in some semblance of testability.

Answer 9

Humans see things in 2D+1, if it was pure 3D we would see inside things, like X-rays.

Answer 10

I've always believed that the 4th demension is accually time, after all time is nothing but a fabric.
