The Amazing Fine Tuning of the Universe

B"H



In his best-selling book, "A Brief History of Time", Stephen Hawking
(perhaps the world's most famous cosmologist) refers to the phenomenon as "remarkable."

"The remarkable fact is that the values of these numbers (i.e. the constants of physics) seem to have been very finely adjusted to make possible the development of life". "For example," Hawking writes, "if the electric charge of the electron had been only slightly different, stars would have been unable to burn hydrogen and helium, or else they would not have exploded. It seems clear that there are relatively few ranges of values for the numbers (for the constants) that would allow for development of any form of intelligent life. Most sets of values would give rise to universes that, although they might be very beautiful, would contain no one able to wonder at that beauty."

Hawking then goes on to say that he can appreciate taking this as possible evidence of "a divine purpose in Creation and the choice of the laws of science (by God)" (ibid. p. 125).

Dr. Gerald Schroeder, was formerly with the M.I.T. physics department. He
adds the following examples:

>> 000000000000000001,
>>

-Perhaps this "beautiful Idea" Prof. Wheeler wonders about, is G-d's Divine Idea. Chassidic thought explains, that when G-d Created the world, His sole Desire and plan was that we would ultimately make a home for Him on this very earth, by transforming the physical into the spiritual. How? Through fulfilling His Divine Will by performing Mitzvot (for ex., when a man wraps physical 'Tefillin' at the behest of G-d, or a woman lights physical candles to honor Shabbat), he and she are transforming this physical world into 1 big Mitzvah, i.e. a home for Hashem, thereby bringing closer the unity of heaven and earth.

Now let's do our best to do one more good deed and learn a bit more Torah, to bring this Intention of G-d's into its ultimate reality, with the coming of our Righteous Mashiach! May it be speedily in our days, before you even sign out of your e-mail account!

~Shabbat Shalom!~
