[Physics] Cosmology

[Arend Lammertink]

Hello Olli,

This is an interesting question and you are not alone in your notion that
mathematics seem to be the most important requirement for physics these
days, while fundamental ideas and even common sense seems to have been
replaced by pages of equations.

In that respect, it is interesting to quote none other than Albert
Einstein, as I did in my background article:

https://en.wikiquote.org/wiki/Albert_Einstein

"Concepts that have proven useful in ordering things easily achieve
such *authority
over us* that we forget their *earthly origins* and *accept them as
unalterable givens*. Thus they might come to be stamped as "necessities of
thought," "a priori givens," etc. The path of *scientific progress is often
made impassable for a long time by such errors*. Therefore it is by no
means an idle game if we become practiced in analysing long-held
commonplace concepts and showing the circumstances on which their
justification and usefulness depend, and how they have grown up,
individually, out of the givens of experience. Thus their *excessive
authority* will be broken. They will be removed if they cannot be properly
legitimated, corrected if their correlation with given things be far too
superfluous, or replaced if a new system can be established that we prefer
for whatever reason." Obituary for physicist and philosopher Ernst Mach
(Nachruf auf Ernst Mach), Physikalische Zeitschrift 17 (1916), p. 101


"I fully agree with you about the significance and educational value of
methodology as well as history and philosophy of science. So many people
today — and even professional scientists — seem to me *like someone who has
seen thousands of trees but has never seen a forest*. A *knowledge of the
historic and philosophical background* gives that kind of *independence*
from *prejudices* of his generation from which *most scientists are
suffering*. This *independence* created by philosophical insight is — in my
opinion — the mark of distinction between a mere artisan or specialist and *a
real seeker after truth*." Letter to Robert A. Thorton, Physics Professor
at University of Puerto Rico (7 December 1944) [EA-674, Einstein Archive,
Hebrew University, Jerusalem].


Now getting back to your question: is the Universe expanding?

Main stream science may think the answer to that question has been solved,
but when one considers that the measurements by which they have come to
this conclusion are based on the fundamental assumption that the speed of
light is constant across the Universe, while this is not the case IMHO, one
is tempted to come to the conclusion that science actually has no idea what
they have been measuring and therefore one has to take their answers with a
big grain of salt for the time being.

The video I posted by David LaPoint shows very interesting connections
between what can be done in a laboratory and patterns we observe at a
galactic scale:

For me, it's still an open question whether or not the Universe is actually
expanding, but perhaps others have another perspective to share.

Regards,

Arend.
