What appears to us solid is ultimately both a particle and a wavelength, and on that realm everything behaves as both a particle and a wave.

... still many physicists are convinced to "see" the particle in a cloud chamber or on a scintillation screen, therefore accepting classical particle coordinates as pieces of reality. But what one concludes to see depends on the chosen model of reality, and this model can only be judged by its success in consistently and economically describing the observations (therefore interpolating between them).

According to my attempts to understand them, reality is systematically denied in the Copenhagen interpretation in order to circumvent consistency problems (such as “Is the electron really a wave or a particle?”). If there is no reality, one does not need a consistent description!

Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

All these tattered old bits and pieces have a history and a meaning. A group of them together can seem like the traces left by an ionizing particle in a bubble chamber: they draw the line of a path taken by something too mysterious to see. That path is a story, of course. What scientists do when they look at the line of bubbles on the screen is work out the story of the particle that made them: what sort of particle it must have been, and what caused it to move in that way, and how long it was likely to continue.
Dr. Mary Malone would have been familiar with that sort of story in the course of her search for dark matter. But it might not have occurred to her, for example, when she sent a postcard to an old friend shortly after arriving in Oxford for the first time, that that card itself would trace part of a story that hadn't yet happened when she wrote it. Perhaps some particles move backward in time; perhaps the future affects the past in some way we don't understand; or perhaps the universe is simply more aware than we are. There are many things we haven't yet learned how to read.
The story in this book is partly about that very process.

One thing most of us agree on is that the universe exists (people who deny that usually follow some trade other than science), so if some theoretical particle interaction would lead ultimately to the nonexistence of the universe, then you can save a lot of electricity by not trying to demonstrate it.
