Was the shock wave generated by it powerful enough to leave
physical evidence on the other side of the world, and would that
shock wave start seismic & volcanic activity that would make matters
worse?

I used the word "object" because that is the
one indisputable thing about it. Whether it
was a meteor(ite) or an asteroid is open to
debate...that it hit this planet is not.

The primary cause of the Cretaceous-Tertiary extinction is the "winter" of abnormally low solar infall because of the dust thrown into the atmosphere by the Chicxulub blast. Secondary effects of the blast include firestorms generated by ballistic infall of ejecta matter, acid rain, intense greenhouse effects from CO2 production, tsunamis, and possibly some earthquakes locally and immediately after the blast. There is no evidence of world-wide increased seismic or volcanic activity as a consequence of the Chicxulub blast. Increased volcanic activity in what's today is India, known as the Deccan Traps, is said to have contributed to the extinction, but the suggestion that the Chicxulub blast helped trigger this volcanism is still controversal. This might be what you're thinking about. It turns out that there is another impact crater in the Indian Ocean off the west coast, called the Shiva Crater, that might be the more probable cause of the Deccan Traps. It's certainly a lot closer.

There is a layer or rock that covers the entire world from the time of the asteroid impact. And Yes additional volcanic activity.

It could, and presumably did. The antipodal point is now in the Indian ocean, so getting evidence would not be easy, even if continental drift had not muddied things, which it undoubtedly has.

you can find iridium al over the earth due to that collision
provoked seismic and volcanic activities i don't know and i can't see why it would have

Isn't there are crater in Mexico that they believe is the one from THE comet that killed the dinosaurs?
yeah, check the link below.

People believe different theories. It all depends. No one really knows!

I think it was an asteroid. Whatcha think, Willis?
