The famous relativity experiment that allowed men to
"see" a star "hidden" by the sun is a good example.

My point was that man's imperfect "laws of physics"
are often violated and have to be revised or discarded
in favor of a new set of laws of physics. If the
scientific progress over the next 1000 years
equals that of the last 1000 years, most of what
we think we know now will no doubt be revised or
proved incorrect and discarded.

Except that isn't true.

Any new physics must encompass and explain everything already proven.

As a simplistic example, relativistic physics doesn't make Newtonian
physics "wrong", discard it or revise it, Newton just becomes a subset,
a special case where if velocity is much, much smaller than c, the
effects of velocity can be ignored.

If some new discovery allows for travel faster than c, relativistic
physics as we now know it becomes a special case for velocity less
than c as it is already experimentally validated and must become
a subset of the new physics.
