If a human fell into a black hole, it would take a long time in our earth reference to complete the fall due to time dilation. So if two black holes collided it should be super slow motion and therefore easy to see due to a steady amplification at the event horizon.
There have probably been BH collisions within our own galaxy. Remember though that a BH is mostly just critically curved space/time, with a tiny singularity in the middle. So what we would expect if two BH's did collide, is more of a sudden deformation of the EH's of both, with gravitational radiation radiating away. A glancing merger [which is a far better terminology then collision] may see the two EH'S stretched into a dumbell like shape, and then gradually settling down with the deformations getting smaller and smaller [much like a plate of jelly that has been shook] until finally settling down to one larger BH. The merging of the Singularities would probably produce similar effects until they came together.
But black holes don't really exist anyway because general relativity is invalid. Gravity is the electromagnetic attraction between all matter therefore Einstein's general relativity is not a valid theory. And now that the Higgs boson has been discovered, general relativity has even more less ground to stand on.
Is that right??? Maybe then you can explain the effects we now put down to BH's in another way? With gravity, you have the job ahead of you. You need to convince the whole scientific community of the validness of your rather extraordinary statement. And how of course the discovery of the Higgs invalidates GR. It's far more likely though, that along with the other weirdos, cranks and pseudoscientific crackpots that infest this forum, you are just plain shit stirring with no evidence at all to support such nonsense.
Ignorant fool. What you say is irrelevant because you're just trolling bullshit nonsense. You need to find another place to spew your intellectually devoid bullshit nonsense.
