US, WASHINGTON (ORDO NEWS) — More recently, Jim Peebles, a cosmologist at Princeton University, presented an article for New Scientist, in which he asked several questions of his own theory about dark matter.
No, the scientist does not believe that he is wrong, but Peebles argues that understanding of physics and the universe is still incomplete and there are fundamental questions that his ideas have not answered.
In his article, the scientist explains that his ideas about the universe arose from early, incomplete measurements. Although scientists have made tremendous progress since then, much remains to be done.
“We have no guarantee that one day we can understand the physical world around us or discover things like dark matter,” Peebles argues.
“But there is no doubt that physics is still moving forward. Think about how successfully scientists and engineers can control the behavior of electrons, atoms and molecules, as well as electric and magnetic fields in cell phones. And all this was done on the basis of incomplete knowledge.”
Peebles says he often sees physicists notice interesting things and put forward hypotheses before they can be proved. This is an illustration of the fact that we still have a lot to learn.
“I want to say that all branches of physics are incomplete. I am not saying that they are wrong, it just can all be improved. Maybe there is a definitive theory of physics, or maybe it’s all just an endless path. The same is with cosmology. ”
