Roberts Roberts your brother time traveller Paul Davies is a great
scientist because he can extract money from various time machines
built on Einstein's theories of relativity:

"Our best understanding of time comes from Einstein's theories of
relativity....In effect, Sally has leaped nine years into Earth's
future.....Speed is one way to jump ahead in time. Gravity is another.
In his general theory of relativity, Einstein predicted that gravity
slows time."

But your brother time traveller Paul Davies is more than just a great
scientist Roberts Roberts. Paul Davies is a genius because Paul Davies
is ready to start extracting money even from the fact that the speed
of light is variable, a fact that topples Einstein's relativities.
This will happen only if the variable speed of light is introduced by
Paul Davies's friend, Joao Magueijo:

"Was Einstein wrong? The idea of a variable speed of light, championed
by an angry young scientist, could one day topple Einstein's theory of
relativity." Paul Davies

Joao Magueijo says the speed of light varies with time but does not
say it varies with the gravitational potential or the relative speed
of the light source and the observer. In Einstein zombie world this
means money could be extracted from toppling Einstein's relativity, on
one hand, but also from not toppling it and continuing to use it for
building various time machines, on the other. For that reason Paul
Davies and Joao Magueijo are friends. Big friends. Like Don Corleone
and Don Tataglia. Paul Davies and Joao Magueijo know nothing about
people claiming the equation c'=c+v is correct, and do not want to
know anything about them. Those people die in oblivion but sometimes
manage to write a book while dying:
