I was wondering if anybody knows of any experiments that differentiates between tired light and an expanding universe?

"Tired light" is a now-discredited theory that suggests light loses energy as it travels through space, causing it to appear redshifted. This theory was proposed as an alternative to the expanding universe theory, which explains the redshift of distant galaxies as a result of the expansion of the universe.
The expanding universe theory states that the space between galaxies is constantly expanding, causing light to stretch as it travels through this expanding space. This stretching of light results in a redshift, where the wavelength of light appears longer and the frequency appears lower.
No, there is currently no scientific evidence to support the "tired light" theory. In fact, observations and experiments have consistently shown that the expanding universe theory better explains the observations of redshift in distant galaxies.
The "tired light" theory was proposed as a way to explain the redshift of distant galaxies without the need for an expanding universe. At the time, the idea of an expanding universe was not widely accepted and some scientists were looking for alternative explanations.
The expanding universe theory is a key component of the Big Bang theory. According to the Big Bang theory, the universe began as a singularity and has been expanding ever since. The evidence for an expanding universe, including the redshift of distant galaxies, strongly supports the idea of a Big Bang origin for the universe.
