There is no problem more difficult to solve than that created by ourselves.

Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously considers it as a state of higher knowledge.

When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!

It is curious that the human mind could blindly accept an infinite speed but had reservations to accept a finite one, simply because it was too large!

Subjectivity is strange to Science, while Relativity is an objective part of it.

Is numerical equality (forced by the use of specific physical units) the same as conceptual equality? Of course NOT!
