Predicted extra dimensions in theories like string theory are assumed to be small in order to remain undetected in everyday experiments. The idea is that these extra dimensions could be compactified or curled up to subatomic sizes, making them virtually impossible to observe directly with current technology. This compactification allows the extra dimensions to influence fundamental forces and particles in ways that are consistent with our experimental observations.

Do higher dimensions exist in the universe?
The existence of higher dimensions in the universe is a topic of debate among scientists. Some theories, such as string theory, suggest the possibility of extra dimensions beyond the three spatial dimensions we experience. However, these higher dimensions have not been directly observed or proven, so their existence remains speculative.
What are the 11 dimensions of M-theory in layman's terms?
4 of these dimensions are the regular ones most of us are familiar with; 3 of these are spatial dimensions: up-down, left-right and forwards-backwards. The fourth one is a time dimension. In a 4 dimensional space you thus require four numbers to uniquely specify a certain location in space and time. A quick example would be the location of a meeting somewhere on Earth; you'd need four bits of information: the latitude and longitude of the location, the height and finally the time of the meeting. In M-theory physicists assume there are 7 additional spatial dimensions. Thus in M-theory you would need a grand total of 11 numbers to uniquely specify a location in spacetime. These additional 7 dimension are not equal to the regular 3 spatial dimensions in one important aspect; they are curled into small loops. This makes them periodic (if you walk in their direction you will after a while end up where you started), and they are very tiny. You can imagine them as small loops of additional space at every location in our regular 4 dimensional spacetime. These loops cannot be seen however because they are so very tiny. If M-theory is correct we might be travelling in these dimensions all the time, but we don't notice it because they are so small. A good analogy Briane Greene used is that of an ant on a garden hose. For the ant the garden hose seems 2 dimensional (3 if you count time); the ant can move forward and backwards on the hose, but it can also move around along the hose in a circular fashion. But if you stand some distance away the hose appears to be a line, a 1-dimensional object. You do not see the second curled-up dimension because it is too small because you are too far away. In this way the extra dimensions M-theory requires are also hidden, but they might be spotted in modern particle collider experiments such as the LHC, since these can be used to probe the small distance scales where these additional dimensions might become important.
The 3 first dimesons are space The fourth is time. So what does the last 7 contain?
The additional 7 (or possibly 8) dimensions, if indeed they exist, would also be dimensions of space and time, but they would be more curved than the more familiar 4 dimensions of space and time that we know and love.
Can a quantity have unit and still be diamensionless?
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
What is the name for the duration in which a force is applied?
In kinematics the product of Force and Time is called the Impulse. It has the same dimensions as Momentum. Thus Force has dimensions [M][L][T-2], so Impulse has dimensions [M][L][T-1], which is the same as Momentum which is Mass x Velocity. So if you apply an impulse of value Ft to a body it causes a change in momentum MV2 - MV1.
Is a or AAA smaller?
AA is smaller than A because if you think about it, D is large so DD is extra large and A is small so AA is extra small! Are you talking about bras? Cause that is how i answered!

Is extra small bigger than small?
An extra small car is even larger than an extra large car when we wonder the mass to gradually increase but how large it is quickly increases so there is an ample of difference between the two Extra small objects have larger absolute value than small objects but they are smaller on the line as we see them on the left rather than right of the number scales
What is a juniors size small in misses?
it's just a small. if you shop at regular stores they ave sizes small, and extra small. if you shop at stores like Aeropostale, Hollister, American Eagle, Abercrombie & Fitch, or some good Boutique, they have - 3x extra small -2x extra small extra small and small. Trust me i'm an expert when it comes to clothes! Xoxo, Yoopie littlefish
Can fashion be tracked or predicted?
Fashion is about future wear or style, so fashion wasn't predicted in anty time.
Is the hollister extra small the same as the abercrombie kids medium?
Well they are ALMOST the same by being like quarter of an inch difference at the bust. so I'd say that if you are a medium at Abercrombie Kids, you will fit in a Hollister extra small!
What are the dimensions of a pint?
A pint is a measure of volume so its dimensions are [L3].
How do you write a quarter in dimensions?
A quarter is a pure number and so has no dimensions.
How many dimensions are there in our universe?
3 physical dimensions plotted as X,Y and Z. 4 if you count time. Though string theory currently predicts somewhere around a dozen tightly coiled dimensions existing within the ones we know of, it has yet to successfully observe these predicted dimensions. So for the time being, bank on 3-dimensional space moving through time--though that might change if/when we gather new evidence.
What are the dimensions of a triangle?
A triangle is a plane figure so it has two dimensions: length and breadth.
How can one brain be small and intelligent and another large and not so intelligent why the different dimensions?
Size does not always matter. We're talking Quality, not Quantity.
How many dimensions does a triangular pyramid have?
It is a solid object and so has 3 dimensions.
