Everyone looks at the world, and their lives, assuming that they know the truth. This isn’t truth with a capital T but simply the truth about everyday things, like how to drive a car, buy groceries, and do one’s job. We know other basic things that are true, such as when we are awake as opposed to being asleep. In other words, the world works, more or less to our satisfaction.
Somewhere beyond everyday affairs there are experts, professionals, and thinkers who deal in deeper truths, still not with a capital T but getting closer. Scientists especially are trusted to give us the truth about Nature from the most microscopic regions of quanta to the most cosmic regions, where quasars and black holes exist. We trust that if the everyday world is working, science must have a handle on why it works, operating from its deeper perspective.
So it comes as something of a shock, even though it doesn’t touch us personally, that the scientific view of the world is so wobbly that it is on the verge of becoming either untrue or obsolete or both. At the farthest edges of exploration, the basic elements of physics—space, time, matter, and energy—vanish, either because they disappear into a black hole or because the scale of measurement reaches the limit, known as the Planck scale, where there is no way to calculate anything. At the same time there is the whole issue of dark matter and energy, which are barely known and may not be knowable by the human mind, since our brains are set up for regular matter and energy.
