Hi Charles,

I found such a fragment on your page:

"It was widely thought that the universe should endure from
everlasting to everlasting. In order to make this possible Einstein
made a modification to the field equation, by including a repulsive
force to balance gravitational attraction."

You must know that the "gravitational attraction" is an idea from the
Newtonian gravitation, not subscribed to even by Newton himelf, who
similarly like Einstein didn't believe in (spooky) "action at
distance". Einstein happened to eliminate this "force" from
gravitation repalcing it by the inertial force due to curvature of
spacetime. So why are you talking about some "repulsive force" and the
"gravitational attraction" which is dead for almost a century?

And BTW, the remark that "the cosmological term was the biggest
blunder of his life" was made by Einstein not because of the math
(which is obviously flawless) but since after this discovery he was
botherd by every cosmologist and his brother until Enstein has
forbidden his secretary to let in anybody who wanted to talk with him
about the universe (soure: Roy Glauber, my teacher and Einstein's
coworker). Apparently George Gamow didn't have Einstein's sense of
humor and didn't get the joke (or didn't want to). How anyone could
think that the discovery of the cosmological constant could be a
blunder?
