Is there a 5th dimension?

Question

1st and 2nd are width and height, the 3rd is depth and 4th is time. What is the 5th dimension?

I'll come back and give 10 points to the clearest answer.

I remember hearing about the 11 dimensions in string theory. Can you name each one?

Answer 1

We can't sense the so-called higher dimensions. And, in truth, dimensions 5 on up are strictily hypothetical. That is to say, there have been no falsifiable observations or experiments to validate the theories that posit the higher dimensions.

String theory, which is not really a theory but a hypothesis, uses higher dimensions to explain what has been observed in our 4D space time universe. When mathematically reduced to the 4 dimensions of our universe, the higher dimensions predict subatomic particles that have been observed...like gluons, photons, bosons. They even predict at least one that has never been observed...the graviton. [See source.]

Mathematically reducing higher dimensions to our four obeservable dimensions is hard to visualize. But it's kind of like casting the shadow of a 3D ball onto a 2D flat table.

If we were two dimensional people living on that table, we could look at the shadow and mathematically hyponthesize something like a spherical ball in 3 dimensions. We would not see that ball because our vision is limited to just the 2 dimensions we live in. But our minds could mathematicall conjure up a spherical shape...the ball, that could cast such an observable shadow in our 2D universe.

When we reduce dimensions like that, we call the result the projections. The higher dimensions of string theory are mathematically projected onto the 4D space time of our extended universe. And those projections are what we see as the predicted gluons, bosons, photons, and gravitons. Each of the four predicted particles is a messenger particle carrying the message of the force they are associated with. [See source.]

Gluons carry the strong atomic force message that keeps atom cores from flying apart. Vector bosons carry the weak atomic force message that also acts within the nucleus. Photons carry the electro-magnetic (EM) force message, which is why magnets attract and repel. And the graviton carries the gravitational force message, which gives you weight when you step on the bathroom scale. And, of the four, only the graviton has yet to be observed.

Until it is experimentally validate, string theory and its higher dimensions remain a WAG...a hypothesis. And, like the two dimensional people living on the table top are unaware of what the third dimension really is, we have no clue what the names of those higher dimensions might be. We don't even know what they look like.

There are two opposing WAGs however. One hypothesis is that the higher dimensions are tightly wound up little circles about one Planck length (10^-33 cm) long. The other hypothesis is that the extra dimensions are larger than our universe; so they lie outside it. Both WAGs are posited to explain why we can't sense the higher dimensions. [See source.]

Answer 2

there is no more than 3 dimensions beyond our perception of space. time is often added as a fourth dimension since it is a variable in its own right, and of real importance in space-time relativistic mechanics. Be that as it may, you cannot attempt to assign more than those dimensions to our everyday life. Higher dimensions are used in solving quantum mechanical problems, of which the most topical today is string theory.

Answer 3

You'll find the 5th dimension between the fourth and sixth. They don't have names - just numbers. Sad really.

Answer 4

there are supposedly 11 dimensions 1d 2d 3d(space) 4D(TIME) and the 5th one is....cant remember lol

Answer 5

Yes. Only the blissful mind can see it.

Answer 6

no.

'clear as i can make it.
