Wave of Gravity

Waves of gravity that distort the space and time have been officially announced that it was detected for the first time. I think it was a very good announcement, new era of astronomy world has coming. The announcement has been carried out at 10:30 pm (GMT+7), february 11, 2016.

In this big announcement, the researchers from the Laser Interferometer Gravitational-Wave Observatory (LIGO) reported the detection of gravitational waves with enough detail. The signal is obtained by LIGO from the collision of two Black Hole that have been detected since 14 September 2015 with the twin LIGO in Livingston, Louisiana and Hanford, Washington.

The collision of two Black Hole is sending a gravitational "flowing" to the entire space with the speed of light, causing ripples in the fabric of space-time, similar to how a pebble dropped in a pond water- via info astronomy

Then, I have a question. How about The law of gravity newton? What about gravity theory (gravity is a force that has dropped an apple that inspired Newton to find the laws of gravity) I've learned in school? Actually I have so many questions about this universe. How actually universe work. Forget about my questions that kinda like a wave of gravity, because It's time to go to a place that more strange and more scare than a black hole school. Bye. Have a good day.
