“The difference of more than 40 degrees between the orbital axis and the
black hole spin was completely unexpected. Scientists have often
assumed this difference to be very small when they have modelled the
behaviour of matter in a curved time-space around a black hole. The
current models are already really complex, and now the new findings
force us to add a new dimension to them,” Poutanen states.
Astronomers have a thing for big explosions and collisions,
and it always seems like they are trying to one-up themselves in
finding a bigger, brighter one. There’s a new entrant to that category –
an event so big it created a burst of particles over 1 billion years
ago that is still visible today and is 60 times bigger than the entire
Milky Way.
That shockwave was created by the merger of two galaxy clusters
to create a supercluster known as Abell 3667. This was one of the most
energetic events in the universe since the Big Bang, according to
calculations by Professor Francesco de Gasperin and his time from the
University of Hamburg and INAF. When it happened over 200 million years
ago, it shot out a wave of electrons, similar to how a particle
accelerator would. All these years later, those particles are still
traveling at Mach 2.5 (1500 km / s), and when they pass through magnetic
fields, they emit radio waves.
Those radio waves are what Dr. de Gasperin and his colleagues observed
using a new telescope array in South Africa known as MeerKAT. Radio
signals alone weren’t enough to characterize the shockwave itself,
though – the XMM-Newton X-ray observatory also spent some time focused
on Abell 3667. …
Elements of Norse mythology abound in The Lord of the Rings, and none is so compelling as the ring itself. The One Ring is reminiscent of magic rings in Norse lore, especially Odin’s Draupnir or Andvararnaut from the legend of the Volsungs, although Tolkien’s ring has a will of its own and cannot be used for the good.
An Ex-North Carolina police chief accused of faking his suicide was found and arrested in Horry County, South Carolina, the agency said on Facebook.
Former
Chadbourn Police Chief William Anthony Spivey was located near Loris,
South Carolina, near the North Carolina border, on February 24,
according to the Facebook post.
Spivey
was relieved of duty due to misconduct allegations last spring. At the
time, he faced over 70 felony charges, including evidence mishandling,
drug trafficking and embezzling, the Horry County Police Department said
in the post. …
This blog is mostly so I can vent my feelings and share my interests. Other than that, I am nothing special.
If you don't like Left Wing political thought and philosophy, all things related to horror, the supernatural, the grotesque, guns or the strange, then get the fuck out. I just warned you.
