the way we interact with the universe
around us has been changed forever
welcome to watchmojo.com down five
need-to-know facts about Einstein’s
gravitational waves number five what our
gravitational waves gravitational waves
were first predicted in 1916 by Albert
Einstein as part of his theory of
general relativity the waves are a
transportation of energy through
space-time whenever an object
accelerates or moves the effect is
similar to that of a boat traveling
through water creating ripples or of a
heavy object being dropped onto a
trampoline shifting tension toward the
center crucially gravitational waves
travel unimpeded across the universe
whereas light may become blocked out or
softened over space and time
gravitational waves are unchanged by
intervening matter between their source
and us therefore to receive
gravitational waves is to engage with
parts of the universe previously
impossible for humans to observe number
four what is general relativity the
general theory of relativity was
published in 1915 and forms the basis
for Einstein’s prediction that
gravitational waves existed it’s
essentially a rethink of Isaac Newton’s
classical law of universal gravitation
developed in the late 1600s Einstein’s
theory says that gravity isn’t a
specific force but the natural result of
matter and energy existing in space-time
large objects such as the Sun and Earth
displace energy in space-time and pull
smaller objects like people for example
in words the idea allows us to view the
universe as though it’s a kind of
landscape a geometry in which the place
and movement of all objects planets
included are dictated by the curvature
of space-time in which they exist
therefore because of the apparently
infinite reach of gravitational waves
the theory can also help us understand
the history of the universe
potentially as far back as the beginning
of time number three how were they
discovered the first detection of
gravitational waves occurred at almost
950 one coordinated Universal Time on
September 14 2015 the observation which
consisted of a chirp signal lasting 0.2
seconds was recorded by the laser
interferometer gravitational-wave
Observatory or LIGO detectors at Hanford
Washington State and Livingston
Louisiana after follow-up tests and
analysis the recording was granted a
confidence level of 99.9999 4% and
presented as an almost certainly
legitimate result the signal came from
the merging of two black holes over 1.3
billion light years away from Earth the
black holes would have been spiraling
toward each other with increasing
velocity before combining at which point
the gravitational wave was strong enough
to be detected by the most sensitive
technologies on earth executive director
of Lego David Wright zja announced the
breakthrough on February 11th 2016 we
have detected gravitational waves
we did it number two how did the world
react across the planet scientists
greeted this chirp with excitement
rights explained that quote up until now
we have been deaf to gravitational waves
but today we are able to hear them while
dr. Sabo marca an astrophysicist at
Columbia University said quote the skies
will never be the same
renowned Royal Society Professor Brian
Cox said quote this opens up an entirely
new way of observing the universe
professor Alberto Vecchio of the
University of Birmingham and a member of
the team behind the detection elaborated
quote this observation marks three
milestones for physics the first
detection of gravitational waves the
first observation of a binary black hole
and the most convincing evidence to date
that nature’s black holes are the
objects predicted by Einstein’s theory
for professor Carsten Dodds none of the
Max Planck Institute for gravitational
physics the significance is clear
he says quote there’s a nobel prize in
it there is no doubt
number one what does this mean for
science this has been labeled as one of
the most important developments in
modern science on a level with the
discovery of the Higgs particle and the
decoding of DNA it’s also been listed as
the most significant step in our
understanding of space since Galileo
pioneered the telescope humankind is now
able to hear the universe beyond even
that which it can see and the LIGO
detection could be a major step in
answering humanity’s greatest questions
scientists anticipate similar detections
to occur with increasing frequency
especially regarding some of the
universe’s most powerful and destructive
events such as neutron star collisions
looking further into the future though
gravitational waves could help us
understand previously invisible dark
energy and then there’s the ultimate
quest to provide an answer to the
ultimate question
42 theoretically there should be
gravitational waves out there carrying
the imprint of the Big Bang which could
provide humans with details as to how
and why the universe was initially
created did these facts get you thinking
yes yes I thought it over quite fine to
vote for which news story is covered
