explosion, but no gravitational waves..
It is under this title that, on January 16th, 2008,
Physicsworld.com learns us that
Ligo did not discover gravitational waves connected with the "Gamma
Ray Burst" GRB070201.
We shall appreciate all the exotic savour of this Jim Hough's comment
(Glasgow University) reported by
Either the source was not a coalescing binary or there is some exotic
situation where the gravitational waves disappear into another dimension.
Manifestly Jim Hough does not envisage the eventuality that the
Relativity would be faulted, for the first time.
On the absence of gravitational
waves, we can make several hypotheses:
The object ( GRB070201) was not a binary
object. (Another atypical case?)
The GRBs are not binary objects. (Why not.)
Ligo is not rather sensitive to discover them. (It
would amaze us, Americans know how to work)
The gravitational waves are not emitted in the
spectre of frequencies to which Ligo is sensitive. (Why not)
The gravitational waves were absorbed in the
intergalactic and interstellar environment. (Quite unlikely)
The gravitational waves dont exist. (In that case,
we forget the Relativity, we forget Big Bang)
We are keen to see the suite of the observations.

explanation for the abnormal rotations observed in galaxies. .

discrepancy in measures of the Hubble constant, which quantifies the
expansion of the Universe, has only grown in recent years. The Hubble
constant tells us the speed at which galaxies are receding from
us as the Universe expands. Over the past five years, cosmologists
have recognized that there is a discrepancy between different
measurements of this fundamental parameter. Three speakers in a
session at the
April Meeting of the American Physical Society in Columbus, Ohio,
discussed the status of this “crisis
in cosmology.” The field has now accepted that the problem is
real, and some researchers are optimistic that it could lead to

New On October 17, 2018, ESO
informs us of the discovery of the largest proto-superamas of galaxies
https://www.eso.org/public/france/news/eso1833/?lang. Thanks to
the Very Large Telescope of ESO, astronomers have discovered a cosmic
giant hidden in the young Universe. They named it Hyperion. It is only
2 billion years after the Big Bang. This seems impossible if one
believes the current theories. We can propose two hypotheses to
explain this: Either the speed of light is not constant, or the
universe is much larger than imagined. These two hypotheses are not
exclusive of each other.
