I am Alpha and Omega,
the beginning and the end.
I will give unto him that is athirst of the fountain of the water of life freely.
Revelation 21:6
"Astrophysicists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Collaboration have found evidence for gravitational waves that oscillate with periods of years 
to decades....In 1916, Albert Einstein proposed space-time as a four-dimensional
fabric, and that events such as exploding stars and merging black holes
create ripples — or gravitational waves — in this fabric.
The authors transformed our region of the Milky Way Galaxy into an immense gravitational-wave antenna using millisecond pulsars.
The researchers examined 15 years of data from three radio observatories.
The widespread spacetime distortion revealed in their findings implies
that extremely massive pairs of black holes may be similarly widespread
across the Universe, numbering perhaps in the hundreds of thousands or
even millions."
