Twoslit & delayed choice according to string theory

In summary, string theory proposes that particles are tiny strings vibrating at different frequencies, which can explain the interference pattern observed in the two-slit experiment. The delayed choice experiment, which introduces a delay between emission and detection, can be explained by the concept of entanglement in string theory. This theory also offers an explanation for the concept of superposition in the two-slit experiment. While some experiments, such as the Afshar experiment, have provided evidence supporting the predictions of string theory, more research is needed to fully understand its implications on these experiments.

String theory is touted as bridging the gap between general relativity and quantum mechanics, so I'm presuming it can explain everything in QM.

How does string theory explain the results of the two slit experiment and the delayed-choice experiment?

(pop science reader's answer, if possible, please)

String theory is still quantum; it can't EXPLAIN quantum phenomena because it IS a quantum phenomenon. So SST doesn't say anything more about these issues than QM does.

Or doesn't it? (I know you know what I am thinking right now.)
 

Related to Twoslit & delayed choice according to string theory

1. How does the two-slit experiment work according to string theory?

The two-slit experiment is a thought experiment in quantum physics that involves firing particles (such as photons or electrons) at a barrier with two parallel slits, and observing the resulting interference pattern on a screen behind the barrier. According to string theory, the particles are actually tiny strings vibrating at different frequencies. These vibrations can interfere with each other, creating the observed interference pattern on the screen.

2. What is the delayed choice experiment in relation to string theory?

The delayed choice experiment is a variation of the two-slit experiment that introduces a delay between the particle being emitted and when it is detected. This experiment tests the concept of wave-particle duality, where a particle can behave like a wave or a particle depending on how it is measured. In string theory, this delay can be explained by the concept of entanglement, where the particle's state is linked to the measuring device, causing the observed behavior to change.

3. How does string theory explain the results of the two-slit and delayed choice experiments?

String theory proposes that particles are actually tiny strings vibrating at different frequencies. These vibrations can interfere with each other, creating the observed interference pattern in the two-slit experiment. In the delayed choice experiment, the concept of entanglement can explain the observed behavior of the particle being both a wave and a particle. The state of the particle is linked to the measuring device, causing the behavior to change depending on when it is measured.

4. Can string theory help us understand the concept of superposition in the two-slit experiment?

Superposition is the concept that a particle can exist in multiple states simultaneously until it is observed or measured. In string theory, this can be explained by the idea that particles are actually tiny strings vibrating at different frequencies. These vibrations can create multiple states, which then collapse into a single state when observed or measured.

5. Are there any experiments that have been conducted to test the predictions of string theory in relation to the two-slit and delayed choice experiments?

There have been several experiments conducted to test the predictions of string theory in relation to the two-slit and delayed choice experiments. One notable experiment is the Afshar experiment, which provided evidence for the existence of interference patterns in the two-slit experiment, supporting the predictions of string theory. However, more research and experimentation is needed to fully understand the implications of string theory on these experiments.
