In summary, String/m-theory is a theoretical framework in physics that proposes the fundamental building blocks of the universe are tiny strings that vibrate at different frequencies. It suggests that time may be an emergent property of the universe and aligns with the 4D view of time. The 3D/4D controversy of time is a philosophical debate about the nature of time and string/m-theory challenges the 3D view by postulating the existence of extra dimensions. Currently, there is no direct evidence for these concepts, but some aspects of string/m-theory have theoretical and mathematical support.

how does string theory address 3D/4D Controversy of time

are strings extended in time in the same way they are extended in space?

are entities in string theory extended in time and have "time parts"

is a unstable particle from time t1 to t2 also extended in time, or is it only exist in the present

does string/m-theory favor A-theory time or B-theory time?

given that in string/m theory it proposes 9 spatial dimensions and 1 dimension of time, how does string theory view the dimension of time

FAQ: In string/m-theory and 3D/4D Controversy of time

What is string/m-theory?

String/m-theory is a theoretical framework in physics that attempts to reconcile the two major theories of modern physics, general relativity and quantum mechanics. It proposes that the fundamental building blocks of the universe are not particles, but tiny strings that vibrate at different frequencies.

How does string/m-theory relate to the 3D/4D controversy of time?

The 3D/4D controversy of time is a philosophical debate about the nature of time. String/m-theory suggests that time may be an emergent property of the universe, meaning it does not exist independently but is a result of the interactions of the fundamental strings. This view aligns with the 4D view of time, where time is seen as a dimension alongside the three dimensions of space.

What is the 3D/4D controversy of time?

The 3D/4D controversy of time is a philosophical debate about whether time is a fundamental part of the universe or merely an illusion. The 3D view of time sees it as a flow or passage, while the 4D view sees time as a dimension like space.

How does the concept of extra dimensions in string/m-theory affect the 3D/4D controversy of time?

String/m-theory postulates the existence of extra dimensions beyond the traditional three dimensions of space and one dimension of time. This challenges the 3D view of time, as it suggests that time may not be the only dimension that we experience and raises questions about the nature of time in relation to these extra dimensions.

Is there any evidence to support the ideas of string/m-theory and the 3D/4D controversy of time?

Currently, there is no direct evidence for string/m-theory or the 3D/4D controversy of time. These are still theoretical concepts that are being explored and tested by scientists. However, some aspects of string/m-theory, such as the existence of extra dimensions, have theoretical and mathematical support. The 3D/4D controversy of time remains a topic of philosophical debate.
