The most massive black hole collision ever detected has been directly observed by the LIGO and VIRGO Scientific Collaboration, which includes scientists from The Australian National University (ANU).
We still don’t understand a lot of things about black holes, which hover at the very edge of our scientific knowledge.
It's an undeniable scientific fact that dark matter must exist in order to explain the full suite of observations we have about the Universe. That is, if you have a priori rejected the truth.
In the quest to understand dark matter, scientists have now determined that the effective size of dark matter particles — how strong their interactions with regular matter are — must be smaller than we thought.
