A dove la vita ci trascina?

QUANDO SI ESAURISCE LA PAZIENZA!!!!!!!!!!!

l'evoluzione dell'astronomia

Siamo una cosina cosi estremamente instemabile  rispetto al cosmo infinito e se avessimo rifelesso sull'immensità del nostro cosmo diventrebbero anche i nostri problemi inesetimabili rispetto al potere che ha creato questa immensità complessa davanti la quale la mente si ferma e non riesce ad interpretare. 

The Big Bang

The progress of astronomy – or, more precisely, astrophysics –over the past century, and particularly the past generation, isnot easily pigeon-holed. On the one hand, profound truths have tumbled abundantly

from the sky. Here are four diverse examples:

1. Our universe began some 14 billion years ago in a single

cataclysmic event called the Big Bang.

2. Galaxies reside mainly in huge weblike ensembles.

3. Our neighbouring planets and their satellites come in a

bewildering variety.

4. Earth itself is threatened (at least within politicians’ horizons) by

impacts from mean-spirited asteroids or comets.

On the other hand, ordinary citizens may well feel that astronomers are a confused lot and that they are farther away than ever from understanding how the universe is put together and  how it works. For example, ‘yesterday’ we were told the universe is expanding as a consequence of the Big Bang; ‘today’ we are told it

is accelerating due to some mysterious and possibly unrelated force. It doesn’t help that the media dine exclusively on ‘gee-whiz’ results, many of them contradictory and too often reported

without historical context. I can’t help but savour the pre-1960s era, before quasars and pulsars were discovered, when we naïvely envisioned a simple, orderly universe understandable in everyday terms. 

The one that strikes me most is that 90% (maybe 99%!) of all the matter in the universe is invisible and therefore unknown. We’re sure it exists and is pervasive throughout intergalactic space

(which was once thought to be a vacuum) because we can detect its gravitational influence on the stuff we can see, such as galaxies. But no one has a cogent clue as to what this so-called dark matter

might be.

Masers, first created in laboratories in 1953, were found in space only 12 years later. These intense emitters of coherent microwave radiation have enabled astronomers to vastly improve

distance determinations to giant molecular clouds and, especially, to the centre of our Galaxy.

A scientific ‘war’ was fought in the 1960s as to whether clusters of galaxies themselves clustered. Now even the biggest of these socalled superclusters are known to be but bricks in gigantic walls

stretching across hundreds of millions of light-years. These walls contain most of the universe’s visible matter and are separated from each other by empty regions called voids.

The discovery of quasars in 1963 moved highly condensed matter on to astronomy’s centre stage. To explain their enormous and rapidly varying energy output, a tiny source was needed, and only a black hole having a feeding frenzy could fill the bill. Thus too was born the whole subdiscipline of relativistic astrophysics, which continues to thrive. Quasars are now regarded as having the highest energies in a diverse class called active galaxies. Gamma-ray bursts, the most powerful outpourings of energy known in the universe, only came under intense scrutiny by astronomers in the 1990s (they had been detected by secret military satellites since the 1960s). The mechanism that leads to this prodigious output is still speculative, though a young, very massive star collapsing to form a black hole seems favoured. A decades-long quest for extrasolar planets and closely related brown-dwarf (failed) stars came to an abrupt end in 1995 when the first secure examples of both entities were found. (By a somewhat arbitrary convention, planets are regarded as having masses up to several times that of Jupiter; brown dwarfs range from about 10 to 80 Jupiters.) Improved search strategies and techniques are now discovering so many of both objects that ordinary new ones hardly make news.

Cambiando la società, la cultura e tutte le condizioni della vità per trovare altro modo di pensare però ho capito bene che

LA GENTE  È TUTTA MATTA

È davvero troppo noioso sentirsi cosi stupido, però talvolta le cose che ci girano, ci inducono a visionare gli oggetti cosi in modo irragionevole privo logicamente suscitando la nostra incoscienza di navigare troppo lontano (che sceme) poi la caduta svegliandoci su uno scherzo imbecille privo di qualunque senso. Comunque fa  bene anche alla salute, ci da un po' di immunità dalle scosse. eheheh

Buon pomeriggio

oggi è il mio compleanno

come al solito ahh.

ma questa volta fuori il paese da solo

è la prima volta  in italia

Sono a Venezia "ma che passione"
