Is there such thing as a 4th? demention if yes will we ever find it?

Answer 1

The Fourth Dimension, as it is called, is sometimes used to describe the spatial dimension of time. If we use this description, then the real question is, will we ever travel in time? The answer is maybe, if someone actually invents a time machine. But to use this time machine, we will have to find a way to change our physical manifest so as not to be affected by the speed of light, which is necessary to go beyond if we are to travel back in time. Remember it is impossible to go forward in time as the future has not happened yet. Hope this helps. For more info on the Fourth dimension, visit one of the many free encyclopedias on the web and search there. :)

Answer 2

Many people will say that the fourth dimension is time. And others will talk about four dimension in space (that is, four directions, with the fourth being invisible to us). But to a mathematician, the concept of higher dimensions is more abstract, and the abstraction turns out to be very useful.

So mathematicians routinely define objects and prove theorems involving four dimensions, and higher (up to an infinite number of dimensions)! In courses with names such as "vector spaces" or "higher dimensional topology" you learn about these. As mathematical abstractions, these dimensions are very real.

Often, the results of this mathematical work can be used to develop very good models or theories that relate to the everyday three-dimensional world we know. Einstein's Theory of Relativity is best expressed in terms of four dimensional space-time (length, width, height and the fourth dimension of time). Another physical theory, string theory, works with 10 or more dimensions to describe physics at really small scales.

So what you choose to call "the fourth dimension" depends upon the model you are trying to build. If you are an economist, for instance, and you want to model GDP, you might even say that GDP depends upon the four "dimensions" of money supply, inflation, productivity, and population growth.

Can there really be an object with four dimensions in space (four separate directions)? These objects can certainly be defined mathematically, and although no one can see them, is said that some mathematicians can actually get a very good intuitive feeling for them, based on the shadows they cast in three dimensions.

But after saying all this, maybe your real question is whether we can go from an abstract idea of four dimensions to something we can actually see and touch. That's a great question, but I don't have an answer.

Answer 3

Don't get confused and think that time is actually another dimension like our three spatial dimensions. The math involved in special relativity and Lorentz transformations make it convenient to think of time as a fourth dimension, due to the way it changes along with the spatial dimensions.

If you want to know about a fourth spatial dimension, you may want to read something about string theory, where many dimensions are required to explain various phenomena. The problem with string theory is that we can't detect any extra dimensions, so we cant see if it is right or not!

Answer 4

Time

Answer 5

the 4th dimension is time, although you could also mean a hypercube, basically just a cube drawn in 4 dimensions. the 1st set of figures on the link below are representations of 1,2,3,4,and 5 dimensions...

Answer 6

Yes it is time, but there is more. THe 4th demention is time AND space.

Answer 7

The fourth dimention is usually called time. And we move only foreward in this particular dimention. Although there are theories that hint of some sort of time travel.

Answer 8

That's a good question. I think that would be a mystery man will never discover.

Answer 9

the 4th dimension is time.

Answer 10

the 4th dimension is time. i'm not sure if there is a 5th dimension though!!!!!!!!!!!!!!
