Parallel Universes

At http://phys.org/print256538850.html ... Nikdem Poplawski claims every black hole may contain a new universe and he presents this idea as a solution to a number of cosmic mysteries. The mysteries, of course, are manufactured in the minds of cosmologists but Poplawski at least addresses the fundamentals, what caused the Big Bang? The idea our universe, or any universe, is contained within a black hole is one of those super intelligent ideas that sounds completely whacko.

Evolution of the Solar System

At http://phys.org/print255086031.html ... the solar system, it is thought, is over 4 billion years of age - but its formation may have occurred much quicker than realised, until now. A team of researchers at the Hebrew University in Jerusalem, aided by laboratories in Japan and the US, have come to this conclusion as a result of nucleus samarium-146 (146Sm) dating methodology. However, one can see there are a number of caveats - if not elephants in the room.

Is dark matter hiding under the bed?

At www.physorg.com/print253968343.html it is a serious blow to dark matter theories. At www.world-science.net/120417_darkmatter.html the question is - where is the dark matter? not here, befuddled astronomers have discovered, while at www.dailygalaxy.com/my_weblog/2012/04/milky-way-appears-to-be-void-of-da... which mor less enscapulates the baffling discovery that dark matter does not exist in our galaxy or solar system - only in deep space (or in the heads of some scientists).

Some funny things about the Sun

Tall Bloke says at 10.40pm April 12th, 2012 .... solar physicists have a dreadful insecurity problem due to their problems with understanding the Sunb. The gate keepers over compensate for their lack of ability to make useful predictions by attacking all heretics with the energy that arises from their pent up frustration.

Talkshop talking points

There are some fascinating posts on the blog of Tall Bloke over the last few days - see http://tallbloke.wordpress.com or Tall Bloke's Talkshop. For example, on 3rd April and again, on the 5th, some interesting graphs by Vukcevic. Is the Svensmark theory vindicated by what happened during the last couple of weeks, in reference to that huge sunspot and sbusequent solar flare. On the 3rd April the subject is late 20th century warming - has it got it's origins elsewhere and has it nothing to do with co2?

Neutrinos

At www.physorg.com/print252580354.html ... the South Pole Telescope is being used to explain the mystery of dark energy. The paper is in the Astrophysical Journal and implies an accelerating universe by means of dark energy and neutrinos - thought to be the most abundant particles in the universe (see also http://arxiv.org/abns/1112.54535 and http://arxiv.org/abs/1203.5775).

Gone

The Italian physicist at the head of the team that made the unwelcome claim neutrinos may travel faster than the speed of light, thereby upsetting large numbers of other physicists seriously in thrawl of the Einstein theory, has resignedd after calls for him to be dismissed. They really did not like the idea it seems - see www.physorg.com/print252312960.html. However, we are assured (but for how long I wonder) that another test is still on schedule for later in the year.

Who was Higgs - and what is the Boson?

At www.io9.com March 22nd there is a piece on the Higgs boson and the fact one physicist gave his name to the theoretical particle when there were other contenders actively writing papers and doing research in the same year, 1964. Peter Higgs has been credited with the discovery - or the original hypothesis (as it has yet to be discovered) and yet there were other teams working on a similar project (story comes from New Scientist).

The Sun is putting energy into the atmosphere

This story can  be found at a number of blogs but not necessarily in mainstream media - the BBC have ignored it for example. One to read, probably because it has a lot of comments, is http://wattsupwiththat.com/2012/03/22/whole-lotta-watts-added-to-the-atm... and concerns the recent flurry of eruptions on the Sun - coinciding with nice weather across the UK. NASA scientists say the Sun dumped enough energy in the upper atmosphere to power every household in New York for two years. It is described as a big dose of heat - the biggest since 2005.

Some physics on the edge

At www.physorg.com/print251310652.html ... University of Chicago physicists have experimentally demonstrated that atoms chilled to temperatures near absolute zero may behave like seemingly unrelated natural systems of vastly different scale offering potential insights into links between the atomic realm and deep questions of cosmology - such as the gravitational dynamics of black holes (you have been warned). Article in Science, March 2nd.

At www.physorg.com/print251369454.html ... the subject is the origin of craters on the Moon.
