String Theory (as its predecessors Relativity and Quantum Mechanics) has only one dimension of time.
However it has many more dimensions of space than its predecessors (both had 3 dimensions), as the simplest version of String Theory must have 10 dimensions of space, while more complex versions require more (with no defined upper limit known). The big question is "Why can't we detect those additional 7+ dimensions of space that must be present if String Theory is true?".
Physical objects can only be measured in three dimensions: length, width, and height. These dimensions define the size and shape of objects in space. Any additional dimensions would require advanced mathematical concepts like those found in string theory.
According to String Theory, there are ten dimensions in the universe and plus time which makes it eleven.
The concept of infinite dimensions is a theoretical possibility in some branches of physics and mathematics, such as string theory. While there is no definitive proof of infinite dimensions, it remains a topic of ongoing research and speculation in the scientific community.
[At least] Three. There could be more if string theory or the theory of branes proves to be true.
At the moment we know of 4, the 3 dimensional you know of and space as the 4th. However it is theorized to be 11 dimensions through the string theory. Although the string theory is still under heavy development.
String theory proposes that the universe is made up of tiny, vibrating strings instead of point-like particles. These strings can exist in 26 dimensions, including the familiar three spatial dimensions and one time dimension. The additional dimensions are compactified or curled up, making them difficult to detect at our scale. The existence of these extra dimensions in string theory helps explain the fundamental forces of nature and the behavior of particles in the universe.
Sort of. Superstring theory is solvable only in 11 dimensions. Whether or not these dimension exist and what they mean is still to be determined. Google "string theory".
Humans are not inherently four-dimensional; we experience the world in three spatial dimensions (length, width, height) and one temporal dimension (time). In theoretical physics, particularly in string theory, additional dimensions are proposed, but these are not part of our everyday experience. Thus, while the concept of higher dimensions exists in mathematical and theoretical contexts, people themselves are not four-dimensional beings.
check this page out. http://en.wikipedia.org/wiki/String_theoryAs you can already see the dimensions in string theory are already in knots. Also, the string in string theory are so unbelievably small that we would never be able to see them, let alone tie them into a knot.
If one does the mathematics (which are *WAY* beyond the math level of even most scientists), one finds that string theory works only if one assumes the vibrations are aking place in eleven dimensions. Choose another assumption and the mathematics falls apart. Or, more exactly, the mathe eventually leads to falsehoods. It is SOMETHING like this: if one assumes that there are ten dimensions in string theory, you end up with 1 = 0 Only if you assume that there are eleven dimensions does one get 1 = 1
In physics, there are four known dimensions: the three spatial dimensions (length, width, height) and the fourth dimension of time. Some theoretical models propose additional dimensions, such as in string theory, where there could be up to 10 or 11 dimensions.
Recent advancements in string theory experiments include the use of particle accelerators to test predictions of string theory, such as the existence of extra dimensions and supersymmetry. Additionally, researchers are exploring the possibility of detecting gravitational waves as evidence for string theory. These experiments aim to provide empirical support for the mathematical framework of string theory and further our understanding of the fundamental nature of the universe.
