Assuming that string theory does not rule out point-like particles such as quarks, how can a group of one-dimensional objects be seen as having no dimensions at all?
The concept of point-like particles in string theory refers to the idea that all particles in the universe, including those that make up our physical matter, are actually tiny strings that vibrate at different frequencies. These strings are thought to be the fundamental building blocks of the universe, and their vibrations determine the properties and behavior of particles.
According to string theory, the properties of particles are determined by the different modes of vibration of the tiny strings that make them up. The frequency of these vibrations determines the mass, charge, and other properties of the particles, and the way the strings interact with each other creates the forces between particles.
The concept of point-like particles in string theory is significant because it provides a unified framework for understanding the fundamental forces and particles in the universe. It also offers a potential solution to the long-standing problem of reconciling quantum mechanics with general relativity.
Traditional particle physics is based on the idea that particles are tiny, indivisible units of matter. However, string theory proposes that particles are actually made up of even smaller strings, which can vibrate at different frequencies and give rise to different particle properties. Additionally, string theory incorporates the concept of extra dimensions and the possibility of a multiverse, which are not included in traditional particle physics.
Currently, there is no direct experimental evidence for the existence of point-like particles in string theory. This is because the energy scales required to observe the effects of strings are much higher than what can be achieved in current particle accelerators. However, string theory has made several predictions that have been confirmed by experiments, such as the existence of supersymmetric particles and the holographic principle.
