Its a screenshot of this video:Borg said:How are you concluding that they have decreased in size from a single image?
But as the two black holes come closer, don't their event horizons change shape and size, and perhaps shrink at some radial positions?Borg said:The event horizons are not perfectly spherical due to gravitational effects from each other but they're not decreasing in size.
Yes, it is possible for a black hole to shrink another black hole's event horizon. This can happen through a process called black hole evaporation, where a black hole loses mass and therefore decreases in size.
The process of black hole evaporation is caused by Hawking radiation, which is a type of radiation that is predicted to be emitted from black holes. As this radiation is emitted, the black hole loses energy and mass, causing it to shrink.
Yes, it is theoretically possible for a black hole's event horizon to disappear completely through evaporation. However, this process would take an incredibly long time for a black hole of a significant size, and it is currently not observed in the universe.
When a black hole's event horizon shrinks, the other black hole does not necessarily experience any immediate changes. However, if the shrinking black hole loses enough mass, it may eventually merge with the other black hole, creating a larger singular black hole.
No, it is not possible for a black hole to shrink another black hole's event horizon indefinitely. As a black hole loses mass through evaporation, it eventually reaches a point where it can no longer continue to shrink, and it will stabilize at a certain size.
