Mid-morning.
Pancakes and bacon for breakfast; it is a nice change of pace with Kim and the
boys here. – Amorella

Astronomers say [the]
universe expanding faster than predicted

Cape Canaveral, Fla. (Reuters) - The universe is expanding
faster than previously believed, a surprising discovery that could test part of
Albert Einstein's theory of relativity, a pillar of cosmology that has
withstood challenges for a century.
The discovery that the universe is expanding 5 percent to 9
percent faster than predicted, announced in joint news releases by NASA and the
European Space Agency, also stirs hypotheses about what fills the 95 percent of
the cosmos that emits no light and no radiation, scientists said on Thursday.
"Maybe the universe is tricking us," said Alex
Filippenko, a University of California, Berkeley astronomer and co-author of an
upcoming paper about the discovery.
The universe's rate of expansion does not match predictions
based on measurements of the remnant radiation left over from the Big Bang
explosion that gave rise to the known universe 13.8 billion years ago.
that travel nearly as fast as the speed of light, which is about
186,000 miles (300,000 km) per second.
Another idea is that so-called "dark energy," a
mysterious, anti-gravity force discovered in 1998, may be shoving galaxies away
from one another more powerfully than originally estimated.
"This may be an important clue to understanding those parts
of the universe that make up 95 percent of everything and that don't emit
light, such as dark energy, dark matter and dark radiation," physicist and
lead author Adam Riess, with the Space Telescope Science Institute in
Baltimore, Maryland, said in a statement.
Riess shared the 2011 Nobel Prize in Physics for the discovery
that the expansion of the universe was speeding up.
The speedier universe also raises the possibility that
Einstein's general theory of relativity, which serves as the mathematical
scaffolding for calculating how the basic building blocks of matter interact,
is slightly wrong, NASA said.
Riess and colleagues made their discovery by building a better
cosmic yardstick to calculate distances. They used the Hubble Space Telescope
to measure a particular type of star, known as Cepheid variables, in 19
galaxies beyond our own Milky Way galaxy.
How fast these stars pulse is directly related to how bright
they are, which in turn can be used to calculate their distances, much like a
100-watt light bulb appears dimmer the farther away it is.
The research will be published in an upcoming edition of The
Astrophysical Journal.

What I like
is that it shows we don’t know everything or even that much about how the
greater nature (the universe) is.
Late afternoon. Everyone had a good time.
The boys were at Pine Hill Lakes Park late morning and Potbelly’s was for
lunch. They left mid-afternoon and arrived home a short time ago. You and Carol
spent the time reading the morning paper and relaxing. Larry M. is coming over
to pick up the condo check next week and you are leaving Thursday. Kim, Paul
and the boys’ flight arrives in Tampa Saturday.
2207 hours. We watched NBC and ABC News then “Bones”
and I watched an episode of season six; “X-Files” titled, ‘Trevor’ when Carol
went upstairs to read. Without Kim, Owen and Brennan here it is surprisingly quiet.
