With the advent of technology, space in projection, prediction, and analysis have all been taken to new levels of understanding. Black holes, particularly in their ability to remain hidden from any sort of visual nature, rendering most of our optics study useless, have benefited most from this when we could measure in other ways, using technology, to locate and find them.
With relativity and gravity at our disposal, it has been found that these black holes, when absorbing stars, tear these stars apart by gravity when they reach the event horizon, which sends out light that would otherwise not be seen, as black holes do not emit any light. Further, with stronger telescopes of different varieties and new techniques to study space, galaxies that showcase interactions with black holes often have a burst of activity where these galaxies were previously thought inactive. On top of this, with the recent studying being done on these black holes and their locations due to interactions they have with gas and stars, enough data has been collected that scientists have taken to projecting when stars and material would interact with such space, which ties back to the idea that black hole collision is also possible and could be projected between the Milky Way and Andromeda. Overall, both of these developments chart growth in the field, but very difficult one. Tidal collision is extremely rare, sometimes occurring only once in 10,000 years, depending on where we study the collision occurring. However, with the fusion of the data collected over time and the new projection ability of supercomputers with the combined knowledge of the data for prediction of these collisions, astrophysicists are hoping to see upwards of hundreds a year.
Understanding and seeing such collisions would deepen our understanding of black holes and of galactic physics to new reaches and standards. Science is, after all, in the business of raising more and more questions with the more we learn.
