Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship. These models have been proposed as alternatives to the models that require metric expansion of space of which the Big Bang and the Steady State cosmologies are the most famous examples. The concept was first proposed in 1929 by Fritz Zwicky, who suggested that if photons lost energy over time through collisions with other particles in a regular way, the more distant objects would appear redder than more nearby ones. Zwicky himself acknowledged that any sort of scattering of light would blur the images of distant objects more than what is seen. Additionally, the surface brightness of galaxies evolving with time, time dilation of cosmological sources, and a thermal spectrum of the cosmic microwave background have been observed—these effects should not be present if the cosmological redshift was due to any tired light scattering mechanism. Despite periodic re-examination of the concept, tired light has not been supported by observational tests and remains a fringe topic in astrophysics.

I'm tired of listening to the sound of my tears,
Tired of constantly battling my fears,
Tired of struggling with challenges that continuously reappear.
I'm tired of wasting my days submersed in despair,
Tired of words piercing my heart like sharp spears,
Tired of living a life...
The brain, like muscles, consumes glucose and ATP (the body's energy molecule) to function.
And at some point, from the strenuous mental process, ATP runs out. This doesn't affect the muscles and other organs because they have their own energy depot.
However, the brain notices the lack of...
