Christianity says:
- Man is the center of the Universe. ( There exist religions with
a different point of view ).
- Man's birth was an extraordinary and unique event.
The most fashioned theory explaining dinosaurs' extcinction -
meteorite
theory - agrees with this christian point of view.
The explosion of a meteorite is a "earthling" event! A unique one.
So, Man's birth, due to dinosaurs extinction is a unique event! Man
is unique. This is a "christian" idea.
If we suppose that gravitational constant
G changes from time to time.
We must admit that this event is not unique. There are, and there have
been lots of great extinctions through the universe.
Man stops being a unique, a sole creature, born after an extraordinary
event.
This theory about which Dirac
thought, disagrees with the way we, men of christian civilisation,
see the world.
Let us say, as an example, that...
The "Big Bang" theory is also a christian one. In that theory,
all the world was born during a magic moment...like in genesis!
After that God needs 15 billions years to finish to build the world
instead of seven days, but it's the same scenario!.
In other religions ( bouddhism, druidism etc...) the way to see the
universe is a different one.
But the majority of the XXth century scientists don't practise these
religions!
