The experiments explained at the links below shed light on the law of constant light speed, c, the qm view, and relativity theory. The experiments include thought experiments and experiments that can be conducted with current technologies. Some of the experiments are well known and some are new or modified experiments that show clearly problems with the concepts of light speed, c, and relativity theory. Therefore, the experiments should be of general academic interest.

Most of the past experiments have been controversial because relativity theory makes ambiguous or conflicting predictions. These experiments have been discussed at length by many experts. They are examples of experimental results that are explained clearly and unambiguously by the qm view, and cannot be explained via the constant-light-speed, c, assumption and relativity theory, which depends on this assumption.

Relativity clocks paradox experiment
This experiment can be conducted with existing technology. It shows that relativity theory causes predictions and observations that disagree with the outcome of the experiment (an indication of flawed scientific theory).

Tube and rod paradox experiment
This thought experiment is an example of the ambiguity inherent in relativity theory. The qm view explanation for the paradox shows that the paradox is an illusion due to an illusion of constant light speed, c.

Light speed, c, experiment
A simple experiment conducted with aircraft and atomic clocks showing that the speeds of light relative to a body change when the body's velocity changes.

Thread-breaking experiment (a.k.a. Bell's spaceship experiment)
A simple thought experiment that shows the confusion inherent in relativity theory (and the resulting disagreement among experts). The qm view does not result in the confusion because it provides a clear understanding of the physical causes of a body's length change due to a change in the body's lengthwise velocity.
