Giant Tunnels

At https://www.earthtouchnews.com/discoveries/discoveries/these-giant-tunne... ... strange smooth walled tunnels cutting into rock faces in Brazil and Argentina have long been a puzzle to locals. You can even stand up in some of them. It was thought they were formed by water dissolving rock - but this is contradicted as the walls show they were made by something with very big claws (below) ...

What Happened Before Big Bang

At https://phys.org/print472815059.html ... what before Big Bang is the title of this piece. The idea is to test inflation of the universe theory after Avi Loeb and others at Harvard and the Smithsonian raised concerns, saying inflation of the universe seemingly has endless adaptability that makes it impossible to test. Falsifiability is supposed to be the mark of a good scientific theory but inflation is such a flexible ideda it cannot be falsified in experiments. No matter what value people measure for some observable attribute there is always an inflation model to explain it.

Strange Behaviour

Strange in the sense that asteroids are not thought to be active - even if that activity is like a sleeping man periodically letting out a wheeze. At https://astronomynow.com/2019/03/20/asteroid-bennu-surprises-with-ejecti... ... NASAs OSIRIS Rex spacecraft, studying the asteroid Bennu by orbiting it (since last December) has sent back some interesting data. There have been a number of 'ejection events' we are told, in which rocky streams of debris can be seen spinning into space.

War and Disaster

Sent in by William - see www.thunderbolts.info/wp/2019/03/18/the-hundred-years-war-the-fires-of-t... ... is a guest post by Peter Mungo Jupp who runs the Ancient Origins web site. Around AD1348 there began the Hundred Years War, a series of skirmishes and full blooded battles that broke out between the kings of England and their former lands in France (as part of the Norman expansion several centuries earlier). It included the famous battles of Agincourt, Crecy, and Poitiers - which have gone down deep into the national psyche of both sides.

Fantasies Pricked

At https://phys.org/print472465406.html ... researchers at the University of Nottingham have found a higher percentage of natural fibres in freshwater habitats and in the atmosphere (in the air we breathe) than microplastic fibres - in the UK. By natural they mean wool and cotton rather than polyester or nylon.

Bingo!

A Chinese fossil trove - see https://phys.org/print472464235.html ... a team from two universities in China and one from the US has partially excavated a trove of fossils from the Cambrian so called Explosion - in southern China. They have also published a preliminary study in the journal Science (March 2019) - see DOI:10.1126/science.aaw8644. The period is best know from a western perspective from the Burgess Shale where internal organs and eyes were preserved. Since then other sites of the Cambrian have been found, all in shale beds.

The One Nobody Saw

At https://phys.org/print472235349.html ... a space rock exploded into a ball of fire above the Bering Sea without anybody actually seeing or reporting it. Not many people live up that way of course - and it was out at sea. The surprisng point is that it was not immediately picked up by scientists. It was discovered on March 8th by a Canadian scientist looking at data used by the Test Ban Treaty Organisation (nuclear tests and big bangs in general).

Graveyard Under Los Angeles

At https://phys.org/print432185795.html ... work on an extension of the Metro system under Los Angeles has found numerous fossilised remains of Pleistocene animals that once roamed the grassland and forest that existed in the Bay area back then -  from mastadons to rabbits, camels to bison and horse bones - to elephant and sabre toothed cats.

Phew

Phew, Saved by the bell. It seems clones of Dr Strangelove types have been blocked by the US, Saudi Arabia, and Brazil - in the nick of time (just as the earth has entered cooling mode). The story is at https://wattsupwiththat.com/2019/03/19/u-s-blocks-u-n-resolution-on-geoe... ... it seems a motion has been derailed at the UN that sought to lace the sky with sunlight reflecting aerosols in order to bring imaginary global warming to an end. One may wonder what the true motive was as aerosols in the atmosphere are quickly washed away.

Galactic Chimney Works

At https://phys.org/print472115260.html ... Australian National University scientists have found that Earth is made of the same elements as the Sun but has less of the volatile elements such as hydrogen, helium, and nitrogen. Rocky planets around stars may be devolatised pieces left over after the formation of stars.
