All four have come from
pairs of black holes spiraling towards one another and then colliding, their colossal masses warping space - time as they merge.
The waves came from
a pair of black holes spiraling together and colliding in space 1.3 billion light - years from Earth.
As
pairs of black holes spiral together, heading towards a collision, they also spin on their own axes - like a pair of figure skaters spinning individually while also circling around each other.

RIPPLE SIGHTING The cosmic dance
of two
black holes warped spacetime as the
pair spiraled inward and merged, creating gravitational waves (illustrated).
The 1000 physicists working with LIGO have twice detected such waves emanating from a
pair of massive
black holes spiraling into each other.
The
pair of black holes might then
spiral around one another before merging to become one large
black hole.
Gravitational waves are created by cosmic catastrophes such as a
pair of black holes locked in a death
spiral before finally merging in a burst
of energy.
This will allow Advanced LIGO to look at the last minutes
of life
of pairs of massive
black holes as they
spiral closer, coalesce into one larger
black hole, and then vibrate — much like two soap bubbles — to become one.
