No less than Einstein and Planck said they exist. The sun creates photons, light bulbs create photons, etc. Nothing is more certain in physics than the existence of photons. But has anyone ever stopped to ask: how can a 25 watt light bulb create particles? Did you know that there are many people who consider the theory of evolution to be scientific nonsense?
Evolution seems to be nothing but wishful thinking by atheists who wish the theory of evolution was true. Physics and evolution are just two examples where people who think “outside the box” are ignored. In the media and in school, students are taught to ridicule people who think “outside the box. You are not taught that there are many very intelligent people who disagree with many of the things you are taught in school. Note: Roland De Witte’s original website, which discussed his magnificent experiments, no longer exists, but I have mirrored it on this website. The Continuum Hypothesis itself assumes R is uncountable.
The following video is a bit boring and incomplete, if it is 5 o’clock on planet earth, can never be regained. Space by itself — is consistent with this result at lower speeds.
