Einstein started everything by precisely defining time as
what we read on clocks. If anyone has a better way of
defining time, he is welcome to try. But he should
remember that physics is about observation and
measurement. Demanding that there 'must' be a universal
time, is not compatible with that.

Yes. That is exactly the point.
You have a clock and a way to measure distances, and
you measure where a stone is after such and such number
of ticks. That is physics.

No time. In relativity a ray of light is not modeled as a
clock carrying observer. No one can fly with a ray of
light, so the question what your clock would do, is
observationally meaningless. If someone would tell you
that his clock would turn into Mickey Mouse, no one
would be able to disprove that.

No one has been there and came back to tell what it
is like, but the theory (that seems to work on the outside),
tells that when you call fall in a black hole, you would
see nothing special about the clock on your wrist. Nothing
strange would happen, at least not for a while. The more
you approach the center, the more you will be ripped apart.

European Builders Confederation?
European Business Council?
Environmental Business Council?
Electronic Bussiness Center?
Effective Business Communication?

I don't know... some group where armchair philosophers
talk about physics without having a clue about it.
