The final wall is devoted to pieces from Ippolito's «Regatta Series» (1984 - 89) in which the watery color planes suggest abstract but recognizable elements like pennants, sails and boats, and
black wave forms blend into blue ground in «Land's End» (1986), with the full blast of wind on sails being felt in the horizontal diptych «Windward» (1987).

A new study published in Physical Review Letters outlines how scientists could use gravitational
wave experiments to test the existence of primordial
black holes, gravity wells
formed just moments after the Big Bang that some scientists have posited could be an explanation for dark matter.
The amplitude and frequency of these
waves could reveal the initial mass of the seeds from which the first
black holes grew since they were
formed 13 billion years ago and provide further clues about what caused them and where they
formed, the researchers said.
Gravitational
waves formed by binary supermassive
black holes take months or years to pass Earth and require many years of observations to detect.
«By combining the detection of gravitational
waves with simulations we could ultimately work out when and how the first seeds of supermassive
black holes

black holes.
The detector, called VIRGO, will try to measure the elusive gravity

form a
black hole.
Those gravity
waves came from two
black holes more massive than any known outside a galactic core and
formed in an environment different than the Milky Way.
This will open up an entirely new window into the gravitational -
wave universal, allowing us to understand galaxy evolution, and is currently the only known way in which we can study supermassive
black hole binaries, and how they
formed.
The first direct detection of gravitational
waves occurred in mid-September 2015 (but announced February 11, 2016) with twin LIGO detectors in Hanford, WA and Livingston, LA (both USA) when ripples of spacetime from the last fraction of a second of the merger of two
black holes with masses 29 and 36 solar masses combined to
form a 62 - solar mass
black hole with 3 solar masses of energy radiated away as gravitational
waves in that last fraction of a second.
As a quasar's
black hole sucks in gas from surrounding space, the gas collides with the edge of its dark - matter halo and
forms a shock
wave, which heats the gas suddenly and strips off electrons to
form electrically charged ions.
They suggest that as two galaxies merged, their respective
black holes settled into the center of a newly
formed elliptical galaxy, creating ripples across spacetime known as gravitational
waves.
When an energetic event occurs (like a
black hole merger or neutron star collision), spacetime becomes violently disturbed and energy is carried away from the event in the
form of gravitational
waves — like ripples traveling across the water's surface after dropping a pebble in a pond.
An analysis revealed the
waves» source: two inward spiraling
black holes that smashed together to
form a single
black hole.
The
black sands of the beach —
black due to the colour of the volcanic rock from which they are
formed — lay virtually deserted for miles apart from the occasional local fisherman, or surfer enjoying uncrowded
waves.
Karen Gunderson's intense
black painting of ocean
waves is built from directional brushstrokes of varying width, and uses the light passing across the surface to reveal her
forms.
