I love it when
New Scientist tackles the big questions. This week it is "What is Reality?" There is a new humility in science, it seems. Many scientists will now admit that we just don't know the answer to the question. Reductionism is no longer convincing. You can examine ever smaller components of the material world (so far we have boiled it down to quarks, leptons, and bosons), only to discover that there may be no bottom level, or that if there is, it is well beyond the reach of observation (minute vibrating
strings in several extra dimensions).
More importantly, since everything from the most elementary particles to the objects we see around us with the naked eye can be described in terms of "wave functions" or waves of probability, existing in a "superposition" of contradictory states until the function is "collapsed" by the act of observation, it seems that the consciousness of an observer has re-emerged as a determining factor in reality itself. Max Planck, the founder of quantum theory, said in 1931, "I regard matter as derivative from consciousness." The
