Experimental Predictions from String Theories

In summary, the conversation discusses specific experimental predictions from string theories that could be confirmed or disproven, including measuring graviton scattering amplitudes and using a trans-Planck energy collider. It is noted that no theory can be unambiguously confirmed and the holographic principle has seen some success. A relevant question about condensed matter applications of ADS/CFT is also mentioned.

Can someone give me some specific experimental predictions that come from string theories--things that at least in principle could experimentally unambiguously be confirmed or disproven?

Thanks.

Thanks.

Since you said "in principle", it's easy. Just measure graviton scattering amplitudes and compare with string theory. You should see an infinite sequence of resonances at beyond Planck energies, due to an infinite number of massive particles in string theory. This task is easily done with a trans-Planck energy collider of galactic size.

If you drop "in principle", then no one knows whether there will be any in our lifetime.

No theory can be unambiguously confirmed. There's always the potential that some future measurement may disprove it.

FAQ: Experimental Predictions from String Theories

What is an experimental prediction?

An experimental prediction is a statement or hypothesis about the outcome of an experiment based on previous observations, theories, or data. It is used to guide and test the experiment's results and determine if the hypothesis is supported or rejected.

Why are experimental predictions important in scientific research?

Experimental predictions are important in scientific research because they provide a framework for conducting experiments and testing hypotheses. They allow scientists to make informed decisions about which experiments to conduct and how to interpret the results.

How are experimental predictions different from theories?

Experimental predictions are specific statements about the expected outcome of an experiment, while theories are broad explanations that have been extensively tested and supported by evidence. Predictions are based on theories, but they are more focused and specific in their predictions.

Can experimental predictions be proven to be true?

No, experimental predictions cannot be proven to be true. They can only be supported or rejected based on the results of the experiment. Even if a prediction is supported by the experiment, it may be revised or disproven by future experiments or data.

What happens if an experimental prediction is not supported by the experiment?

If an experimental prediction is not supported by the experiment, it means that the hypothesis was not supported by the data. This does not necessarily mean that the hypothesis is incorrect, but it may need to be revised or further tested. It is an important part of the scientific process to consider all outcomes, even if they do not align with the initial prediction.
