In this article I demonstrate that the expansion of the Universe is slowing, and not accelerating, as the scientific community claims. In fact I have demostrated that the deduction of accelerating expansion is due to a series of successive misinterpretations of redshift, which in turn are due to a misinterpretation of the result of the Michelson-Morley experiment. However, with a correct interpretation of that result, I have deduced a correct interpretation of redshift and that the expansion of the Universe is slowing.In truth I have been arguing for several years that the expansion of the Universe is slowing, both through discussion in forums and by publishing articles online, and no one has ever managed to confute my demonstrations. But I must also say that the forums and scientific journals frequented by professional astrophysicists are controlled by the scientific community, which has not allowed me to publish my posts and articles there, and therefore they have not been reviewed by them. But recently I discovered the Quora forum platform, which allows anyone, including them, to post and read. So they can review my articles and, if they will be able, confute my arguments.
