Giordano Bruno

Giordano Bruno

Every time we, in the past 500 years, thought we enjoyed a unique cosmic
situation, we were wrong. (1)

The sun did not revolve around the earth which Copernicus demonstrated in
his treatise 'On the Revolution of the Heavenly Spheres' published in 1543
on the day he died.

The earth did rotate - like the other planets orbiting in ellipses around
the sun as Galileo demonstrated in 'Dialogue on the Two Chief World Systems'
published in 1632.

And when Galileo as the first applied the telescope to study the sky, he
observed that the nebulous band of the Milky Way was resolved into a myriad
of stars. (2) Six months after the publication of Galileo's book, he was
summoned to Rome to face the Catholic Inquisition and there, on account of
his defence of Copernicanism, he was found guilty of heresy and had to
remain under house arrest for the rest of his life.

This was a trifle, however, compared to the fate the Catholic Church meted
out to Giordano Bruno who in 'On the Infinite Universe and Worlds' in 1584
aired the intuition that: "Innumerable suns exist; innumerable earths
revolve around these suns in a manner similar to the way the seven planets
revolve around our sun. Living beings inhabit these worlds". (3) Faced with
such a dangerous heresy, the spiritual guide of Christianity, the Catholic
Church, of course had to intervene and Giordano Bruno was duly condemned to
the stake. Before dying in this extremely painful way, a nail was hammered
through his tongue. Since this misdeed, and with its subsequent saveage
determination to kill important scientific advances, it seems fair to ask
whether the Catholic Church is entitled to retain possession of its -
unique - leading position ?

The world picture changed radically during the European Renaissance. But it
is first at the approaching encounter with the planetary candidates for
intelligent life in solar systems near to us (4) that we, finally,
understand the full extent of the intellectual achievement of European
astronomers and philosophers in this era.

Copernicus, Kepler, and Galileo reached full recognition a few decades after
their death for their clear and rather precise description of our solar
system.

Measurement, observation, and rational, unprejudiced thought were
instrumental in this endeavour. The next, natural step was to attempt to
determine the composition and structure of the cosmos outside our solar
system. Here observation and measurement with the primitive instruments of
that time were immediately of little use, which did not make Giordano Bruno
desist from conjecturing about and visualizing the rest of the Universe,
what the self-opinionated Catholic Church and numerous scholars and
astronomers otherwise, with withering sarcasm, even to this day, thought he
should.

Giordano Bruno's affiliation to the hermetic tradition has often been held
up against him (5, 6), but
in reality almost all Renaissance astronomers, incl. Kepler and my
superstitious compatriot Tycho
Brahe were fascinated by spiritual currents that were certainly not pervaded
by rational thought.

The long-drawn-out search to find fault with Giordano Bruno's achievement
includes blaming
Bruno for not having understood the Copernican heliocentric model properly.
The truth is, however,
that the implications of the Copernican model had escaped most astronomers
just after the
publication of De Revolutionibus. (7)

Giordano Bruno was the first serious student in the Renaissance of the
cosmology of Lucretius
(99-55 B.C.). Lucretius asserted that the Universe was infinite. (8) That
Bruno had the courage to
publish On the Infinite Universe and Worlds conjecturing that the Universe
must contain a
multitude of such comparatively simple structures as solar systems and that
some of the planets
of the solar systems are due to be habitated by humans ought to bring him
the credit which is his
due - at 400 years' delay.

In 2001, Martin Rees, Astronomer Royal of Great Britain, stated: "The
concept of 'a plurality of
inhabited worlds' has, ever since (Bruno) had surprisingly sustained
support." (9) Small wonder,
today we have to re-state the achievement of the scholars of the Renaissance
as follows: on the
basis of observation and measurement of relations within our solar system -
a n d i n t u i t i o n
a n d c o n j e c t u r e u n s t o p p a b l y t r a n s g r e s s i
n g i t s b o r d e r s, o n c e
t h e i d e a t h a t t h e e a r t h w a s n o t t h e c e
n t r e o f t h e w o r l d h a d
t a k e n r o o t, they arrived at a vision of our habitated sun system as
one out of many in
the cosmos. This concept will, to all appearances, be confirmed in this or
the next decade.

Et enhver der er udsat for modsigelse og andre former for hetzagtig
forfølgelse fra de autoriserede elite-smagsdommeres side, nødvendigvis
må have ret i hvadsomhelst han påstår.

Det er da indlysende.

Nå bare det! Ja, det ved da enhver idiot. Det kræver næppe tre lange
enslydende indlæg fordelt på 2 grupper :o/

Og idet det tydeligvis er noget vrøvl, og derfor formentlig vil
modsiges, må det være rigtigt.

Det er ikke første gang han har sendt den type indlæg.
