Philosophy: The discovery of the obvious!
On Truth and the Most Simple Sensible Obvious explanation of Physical Reality

The more original a discovery, the more obvious it seems afterwards. (Arthur Koestler)

I have known of the Wave Structure of Matter in Space for ten years and it just seems blindingly obvious to me now that it correctly describes physical reality (how matter exists in Space and interacts with other matter in the Space around it).
The solution is simple sensible and obvious once known, we just never thought about it.
I have collected some quotes (below) relating to this common failure of humans to see the obvious until someone finally discovers it (to me Darwinian Evolution is in this category of being obvious once known).
This is why philosophy is also known as the 'discovery of the obvious' - which is really just a polite way of saying that we humans are blind to the obvious most of the time (and easily misled by our imaginations when it comes to thinking about truth and reality).

Familiar things happen and mankind does not bother about them. It takes a very unusual mind to undertake the analysis of the obvious. (Alfred North Whitehead, Science in the Modern World)

The unapparent connection is more powerful than the apparent one. (Heraclitus)

I deal with the obvious. I present, reiterate and glorify the obvious - because the obvious is what people need to be told. (Dale Carnegie)

There is nothing as deceptive as an obvious fact. (Sir Arthur Conan Doyle)

No question is so difficult to answer as that to which the answer is obvious. (George Bernard Shaw)

That's the way things come clear. All of a sudden! And then you realize how obvious they've been all along. (Madeleine L'Engle)

The obvious is that which is never seen until someone expresses it. (Kahlil Gibran)

Nothing evades our attention as persistently as that which is taken for granted. (Gustav Ichheiser)

Because it’s familiar, a thing remains unknown. (Hegel)

Most human beings have an almost infinite capacity for taking things for granted. (Aldous Huxley)

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes). The real foundations of his enquiry do not strike a man at all. Unless THAT fact has at some time struck him. And this means: we fail to be struck by what, once seen, is most striking and most powerful. (Ludwig Wittgenstein)

This is clearly true, these things which are 'normal' tend to be ignored by humanity even though they are quite amazing when we really think about them.
For example, if we consider Gravity. How remarkable it is that we are stuck to the Earth, and that the earth, moon, planets, sun and all those stars out there in the Space of the universe are all connected by this 'gravity force'. We give it a name and then forget about it - without ever thinking how amazing it is, what really causes it.
How many people think about how they exist in three dimensional space (we never seem to think about Space!) and that we can see stars across the Space of the universe - these are most profound things!
And now we have a simple sensible obvious explanation of these things (how matter is interconnected across the universe) with the Wave Structure of Matter in Space.
So I hope that in time this will become obvious to all of humanity - as then it will become obvious that we are heading for disaster with our current knowledge foundations of discrete and separate 'particles'.

As David Bohm writes;

The notion that all these fragments is separately existent is evidently an illusion, and this illusion cannot do other than lead to endless conflict and confusion. Indeed, the attempt to live according to the notion that the fragments are really separate is, in essence, what has led to the growing series of extremely urgent crises that is confronting us today. Thus, as is now well known, this way of life has brought about pollution, destruction of the balance of nature, over-population, world-wide economic and political disorder and the creation of an overall environment that is neither physically nor mentally healthy for most of the people who live in it. Individually there has developed a widespread feeling of helplessness and despair, in the face of what seems to be an overwhelming mass of disparate social forces, going beyond the control and even the comprehension of the human beings who are caught up in it. (David Bohm, Wholeness and the Implicate Order, 1980)
