The collision of a pair of colossal, stellar-mass black holes has made itself heard, nearly 3 billion light years away, through a cosmic microphone on Earth.
On Jan. 4, the Laser Interferometry Gravi...
The direct detection of gravitational waves opens a new window to explore our Universe and indicates the coming of a new era of gravitational wave astronomy. In 2015, the KITPC program on “The Ne...

On Dec. 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time.
The gravitational waves were detected by both of the twinLaser ...
Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be “seen” by looking at the stars. The new model, developed in...
Characterisation of Low Frequency Gravitational Waves from Dual RF Coaxial-Cable Detector: Fractal Textured Dynamical 3-Space

The massive black holes we observe in galaxies today are the natural end-product of a complex
evolutionary path, in which black holes seeded in proto-galaxies at high redshift grow through
cosmic hi...
