Now, the last step. Pls Steve and others let me know if the plots and explanations are clear now. The recently detected waves are plotted in the following official graph
We can clearly see the ripples becoming gradually wider and more frequent, startign from time 0.3 seconds to time 0.42, when they are the highest and the closest.
At time 0.3 the black holes started to approach to each other, increasing significantly in velocity and mass. At 0.4 second the black holes are revolving around each other very, very closely, with velocity at about half lightspeed. The last spikes testify the moments just before the collision, after which there are no more gravitational waves (seconds 0.43 to 0.45) since there are no more two black holes, just a single, larger one which is spinning in a close to circular simmetry, hence radiating no gravitational waves.
The dramatic collision, where two bodies which total mass amounting at about 30 times our sun, has ended. The GWs detected are exceedingly and incredibly tenuos. I still can hardly believe the devices could detect them.
