A New Kind of Coalescence

A blip
the scientific silence.

A split-second signal
has just been detected
by LIGO 1 & Virgo 2.

Four low-frequency ripples
in the far-reaching fabric of spacetime
have successfully traveled

an astronomical distance
of 150 billion trillion km
over seven billion years—half

the age of our universe.
Powerful, primordial gravitational
waves have undulated

from their point of origin—
a place & time
of cosmic cataclysm.

An intermediate-mass black hole
equating 150 solar masses 3
has formed

from the fiery fusion
of a couple of black holes
in the forbidden range of masses.

Two radiantly haloed singularities 4
once spiralled into one another
amidst the solitude of space.

1. LIGO is the Laser Interferometer Gravitational-Wave Observatory. This observatory houses an interferometer—an instrument designed to detect gravitational waves.
2. Virgo is a type of interferometer—an instrument designed to detect gravitational waves.
3. A solar mass is the mass of Earth’s sun—approximately 2,000,000,000,000,000,000,000,000,000,000 kg.
4. A singularity is the centre of a black hole. It contains an extremely high mass of matter within an infinitely small space.
