are there other dimensions in our universe?

Answer 1

Yes, there are. A 'dimension' is any magnitude (or value) which cannot be derived from the other values defining a thing. (Mathematicians like to say they are 'linearly independent ☺) For example, one can measure people by height, weight, gender, hair color, and eye color. All of these things are independent since knowing a person is 167 cm tall, masses 60 kilos, is male, and has brown hair tells you *nothing* about the color of their eyes.

In the same way there are the usual 'dimensions' of length, width, and height. But there are also things such as time, charge, spin, strangeness, charm, color, etc. that are also 'dimensions'.

Answer 2

Other dimensions, besides what?

As humans, our ability to experience the universe is only limited by our senses.

Our senses consist of touch (from which we can experience the three orthogonal dimensions of space, as well as temperature, a possible fourth dimension?), sight (from which we can experience the three orthogonal dimensions of space, as well as colour/color and intensity, other possible dimensions), hearing (from which we can experience the three orthogonal dimensions of space, as well as pitch, and volume other possible dimensions), smell (which does not give us experience of physical space), and taste (which, again, does not give us experience of physical space). There may be other "hidden" senses, but these are the basic five.

So, that makes 10 dimensions so far.

Time is sometimes considered as a "dimension", however I would argue that time is a figment of our memory. Take away our memory, and time is meaningless.

Hope this helps.

Answer 4

i remember reading somewhere that this universe contains 90 or 99% of dark matter .if that is true there is a great chance for other dimensions to exist...
and some experts consider time to be a dimension...

Answer 6

yes, but they are not what you would expect to think about dimentions. there are many dimentions. one is length, one is width, height. these 3 dimentions tell you precisely where in space you are. (yeah, there was an explosion on the 7th hole of the TW Golf course) another dimention, a 4th dimention, is time. when in space. (there was an explosion on the 7th hole of the tw golf course at 6pm yesterday). ok, another dimention is temperature. (the explosion on the twgc at 6pm yesterday had to be at least 2000 degrees in the center) another dimention is color. (the explosion at 6pm yesterday on the course looked blue at first, then as you move along the time axis it turned yellow then orange). then you move along the height axis and the color changes to black, because now you are looking at smoke. so as the height changes, there is a change of the value on the color and temperature axis. these are dimentions whether you like it or not. think about it. what are the dimentions of that box? 4x3x9. you can plot that on the xyz 3D axis. we can also do this; x axis is box size, y axis is box weight, z axis is box's velocity. can only graph something by 3 of it's dimentions, but since there are so many, you can have very different graphs for the same thing.

Answer 7

That's a hot topic in physics right now. So far, no one has devised an experiment that would shed any light on the matter.

Answer 8

For all practical purposes no, there are only 4 that are detectable by our senses. However in theory there could be more, buts what does it matter...

Answer 9

there are said to be twelve...
