I can provide some general information.
Without specific details about David Mota's assertion or the context in which he made it, it's challenging to comment on his statement directly. However, it is not uncommon for scientists and researchers to challenge existing theories and propose new ideas or alternative explanations. Scientific progress often involves questioning established knowledge and continually refining our understanding of the universe.
In the field of cosmology, our understanding of the cosmos has evolved over time, and theories have been revised or replaced as new evidence emerges. For example, the discovery of dark energy, which is believed to be responsible for the accelerated expansion of the universe, was a surprising and transformative finding that challenged previous assumptions.
It's important to note that scientific theories are based on the available evidence and observations at any given time. While they provide the best explanations we have, they are subject to revision as new data becomes available. Scientists engage in ongoing research, experimentation, and observation to test and refine existing theories or develop new ones.
Ultimately, the validity of any assertion, including David Mota's, would depend on the evidence and arguments supporting it. It is through rigorous scientific inquiry, peer review, and consensus-building that our understanding of the cosmos progresses.
