Hi Snowflake,
Hope life is good to you,and you well and happy.
The first law in this forum is challenging accepted wisdom,that
is why I contribute.There are are those who believe what they are
told,and those who question what they are told,I am of the latter.
And I think this is what this site,and it's host,is all about.
In the spirit of friendly reply,cannot understand your difficulty with
the concept of the configuration of the light from a pulsar,that is,from
the point of view of the independant observer.Lightspeed is fixed,
a beam of light traversing the universe????.
Take your point about expanding into what,so many things we have
not the knowledge or imagination to conceive of,yet.But that does not
excuse those who do their best to tell us,we are the students,and their
knowledge is not to be challenged.If I may,share many of your thoughts
Snowflake,enjoy discourse with you.
