In summary, there should be no observable difference between the two scenarios of black hole mergers mentioned.

Would there be any observable difference between these two cases: A) two "ordinary" black holes merge. B) one of the two merging black holes is derived from anti-matter? Thanks for any thoughts.

There should be no difference.
1. Black holes do not have 'solid surface'
2. When any matter approaches singularity inside the horizon, it becomes a subject of so heavy tidal forces/hawking emission from apparent horizons/heating that the difference between matter and antimatter dissapears (like it was at some point of history soon after the Big bang)

According to the "no hair" theorem, the only externally observable properties of a standard classical black hole are mass (rest energy), electric charge and angular momentum, so there is no observable distinction between one made of matter and one made of antimatter.
 

Related to Black hole merger - what would happen if

1. What is a black hole merger?

A black hole merger occurs when two black holes come close enough to each other that they begin to orbit each other and eventually merge into one larger black hole.

2. What would happen if two black holes of different sizes merged?

If the two black holes have significantly different masses, the smaller black hole would be pulled towards the larger one and eventually merge with it. This would result in a larger black hole with the combined mass of the two original black holes.

3. How does the merger of black holes affect space and time?

The merger of black holes causes a phenomenon known as gravitational waves, which ripple through space and time. These waves cause distortions in the fabric of spacetime, similar to the ripples on the surface of a pond caused by a stone being dropped in.

4. Is there any danger to Earth if a black hole merger were to occur nearby?

No, a black hole merger would not pose any danger to Earth. Black holes have a strong gravitational pull, but they would need to be extremely close to cause any significant effects on Earth, which is highly unlikely.

5. Could we observe a black hole merger happening in real-time?

Yes, scientists have already observed and recorded several black hole mergers using specialized instruments like the Laser Interferometer Gravitational-Wave Observatory (LIGO). These observations provide valuable insights into the physics of black holes and the universe.
