Crackpot alert from Science and Spirit - Connecting Science, Religion and Life
In fact, the work that Rueda, I and another colleague, Hal Puthoff, have since done indicate that mass is, in effect, an illusion. Matter resists acceleration not because it possesses some innate thing called mass, but because the zero-point field exerts a force whenever acceleration takes place. To put it in somewhat metaphysical terms, there exists a background sea of quantum light filling the universe, and that light generates a force that opposes acceleration when you push on any material object. That is why matter seems to be the solid, stable stuff that we and our world are made of.
.. and a little rationality from Sciam.
That conceit is not shared by the majority of physicists; some even regard such optimism as pseudoscience that could leech funds from legitimate research. The conventional view is that the energy in the vacuum is minuscule. In fact, were it infinite, the nature of the universe would be vastly different: you would not be able to see in a straight line beyond a few kilometers.
