No big bang ... no beginning ... and no end.

At www.physorg.com/print199591806.html July 29th (see www.dailygalaxy.com July 30th) ... Wan-Yi Shu has proposed a new class of cosmological model that may bit observations of the universe better than the current big bang model.

Earth's collapsing atmosphere

At www.physorg.com/print198429352.html there is a report on a paper at Geophysical Research Letters June 19th which says there was a contraction of the  thermosphere during the deep solar minimum of 2008-9. It is known to cool and shrink when solar activity is low - but in this instance, the collapse was almost 3 times greater than low solar activity by itself can explain - from their mathematics.

shrinking protons

a paper in Nature July 8th (see www.sciencenews.org ) indicates protons are smaller than previously thought - by some 4 per cent. This doesn't sound a big deal, you might think, but scientists say this could have 'enormous implications' and 'something is 'drastically wrong'. It could be there is something amiss with quantum electro-dynamics, the theory of how light and matter interact by incorporating Einstein's special relativity into quantum mechanics (see also pre-publication news report on In the News last week).

Altitude ... Snowballs ...

http://news.yahoo.com the journal Science (July 2nd) claims Tibetans and Han Chinese separated from each other just 2750 years ago. The group that moved into Tibet dwindled in numbers but the lesser group, remaining at a low altitude, expanded dramatically. As such the Tibetans adapted to a very high altitude in a very short period of time - and the Han went on to dominate China. This story reappears on Daily Galaxy on July 3rd, posted by Casey Kazan.

Neutrino Experiments

www.sciencenews.org/view/generic/id/60568/ June 25th ... Neutrino experiments in an underground laboratory in Minnesota suggest neutrinos and anti neutrinos do not weight the same which might indicate the presence of an unknown force or a violation of Einstein's Theory of Special Relativity.

Neutrinos ... and clouds ...

Meanwhile, at http://calderup.wordpress.com June 14th we have two interesting posts. The first one is on the topic of aeroplanes accidentally making holes in clouds and causing rain or snow to fall. It may happen more often than realised.

Dark matter does not exist?

At www.science.daily.com/releases/2010/06/100613212708.htm June 11th ... scientists at Durham University's Physics department used satellite data to study the remnant heat of the Big Bang - via a microwave anisotropy probe. In the journal Monthly Notices of the Royal Astronomical Society they claim dark energy and dark matter may not exist - the mathematics was wrong. In turn, this may threaten the consensus model of the universe, the Big Bang theory.

The Age of the Universe has changed - and the Big Bang might have been a squib

At www.dailygalaxy.com June 11th .... we have 'You couldn't make this up dept; our universe is 150 billion years old' - it seems a group of international astronomers say the universe is much older than previously thought as modern telescopes and attachments reveal more and more 'rivers of galaxies' forming bands out there in deep space, some of which are 600 million light years apart, and stretch across a large section of what is an expanding universe that threatens to get even bigger while we are reading this and they are looking up into the sky.

Quark Gluon Plasma

www.physorg.com/print195306308.html June 9th ... for a few millionths of a second after the Big Bang the universe consisted of a hot soup of elementary particles called quarks and gluons. A few micro seconds later they cooled to form protons and neutrons - the building blocks of the universe.
