An artist's impression
of gravitational waves generated by binary neutron stars.
The first two detections
of gravitational waves generated by the collision of two black holes were reported last year.

Physicists could look for evidence
of other universes using tools designed to measure ripples in spacetime — also known as primordial
gravitational waves — that would have been
generated by the universe's initial expansion from the Big Bang.
These
gravitational waves were
generated by two black holes — eight and 14 times the mass
of the sun — merging together 1.4 billion light years away from Earth.
As early as 2021 it will be joined by the Einstein Probe, a wide - field x-ray sentinel for transient phenomena such as gamma ray bursts and the titanic collisions
of neutron stars or black holes that
generate gravitational waves.
Gravitational waves detectable from Earth are
generated by collisions
of massive objects, such as when two black holes or neutron stars merge.
BlackGEM is going to hunt down optical counterparts

gravitational waves — tiny ripples in spacetime
generated by colliding black holes and neutron stars and detected for the first time in 2015 by the Laser Interferometer
Gravitational - Wave Observ
Gravitational - Wave Observatory (LIGO).
The merger
generates powerful ripples in space called
gravitational waves that kick the newly merged black hole away at speeds
of hundreds or even thousands
of kilometres per second.
Buonanno has led the effort to develop highly accurate models
of gravitational waves that black holes would
generate in the final process
of orbiting and colliding with each other.
Gravitational waves from inflation
generate a faint but distinctive twisting pattern in the polarization
of the cosmic microwave background, known as a «curl» or B - mode pattern.
Of course, LIGO doesn't
generate large
gravitational waves — you could probably make bigger ones yourself by whirling bowling balls around — but it does so with optimal efficiency.
That simple model should
generate strong
gravitational waves, which would leave their own distinctive imprint on the polarisation
of the microwave background.
Inflation would
generate gravitational waves, giving a subtle twist to the polarization
of the cosmic microwave background (CMB), the ubiquitous whisper
of radiation left over from the Big Bang.
If this interpretation
of the observations is correct, it could confirm a 30 - year - old prediction
of the cosmic inflation theory: that the simplest models
of inflation can
generate an observable level
of gravitational waves, comparable to density or temperature fluctuations in the early universe.
Averaging over some 350 high - galactic - latitude patches
of sky similar in size to the region observed by BICEP2, Puget reported that polarization from interstellar dust grains plays a significant role and might account for much
of the BICEP2 signal that had been attributed to inflation -
generated gravitational waves.
Gravitational waves are ripples in the fabric
of space - time
generated by some
of the most violent events in the universe, such as the merging
of two black holes.
According to Einstein's theory
of general relativity, two orbiting black holes will
generate powerful
gravitational waves, ripples in the fabric
of space - time.
The VLA made the first detection
of radio
waves coming from the neutron - star collision that
generated a ripple
of gravitational waves.
Like the historic first detection announced this past February, these
gravitational waves were also
generated by the merger
of two black holes.
A new study suggests that the
gravitational waves detected by the LIGO experiment must have come from black holes
generated during the collapse
of stars, and not in the earliest phases
of the Universe.
Many scientists believe that during this brief moment, the monumental expansion
of the cosmos would have
generated gravitational waves.
Although scientists have theorized that short GRBs are
generated by colliding neutron stars, only with the help
of gravitational wave detectors could this be confirmed.
Dense star clusters may serve as breeding grounds for successive generations
of black hole mergers, resulting in gargantuan holes,
generating gravitational waves that researchers hope to detect.
The California Institute
of Technology and Massachusetts Institute
of Technology designed and operate the NSF - funded LIGO that is aimed to see and record
gravitational waves for the first time, allowing us to learn more about phenomena like supernovae and colliding black holes that
generate the
waves.
The
gravitational waves were
generated by the merger
of two medium - size black holes about 1.3 billion years ago, researchers said.
