Of course, technical authors avoid absolute assertions because they know
that almost all knowledge is proven inaccurate sooner or later by the
additional acquisition of human knowledge driven by finer-tuned
experiments. What you don't seem to understand is that technical knowledge
builds upon technical knowledge so that the latest theories that support
the latest experiments are the best "knowledge" that we have so far.
Without the 19th century giants in the field of physics, we couldn't have
progressed this far, but those giants were simply ignorant of 21st century
physics.

The Giants discovered in XIX century that light is the oscillatory flow of
electrons.

Today we too, are still ignorant to a certain extent, but hopefully less
ignorant than 19th century folk.

In XX century was done the first rectenna: "A rectenna is a rectifying
antenna, a special type of antenna that is used to convert microwave energy
into direct current electricity. "
In XXI century are the optical rectennas.

But the first were the crystal radio:
"The simplest crystal radio receiver, employing an antenna and a
demodulating diode (rectifier), is actually a rectenna".
From: http://en.wikipedia.org/wiki/Rectenna

You wrote "latest theories that support the latest experiments are the best
"knowledge" that we have so far".

But there are plenty of theories. Which one is the best?

To have knowledge means know the facts not theories.
