The Breakthrough Prize is an important prize. First, it’s a big prize for the fundamental sciences, as the name suggests. As far as I know, the prize was designed to be complementary to other famous prizes like the Nobel Prize. The Nobel Prize can only be awarded to individual people – up to three people – but the Breakthrough Prize can be awarded to large groups of people as in case of the Event Horizon Telescope, where hundreds of people were part of the team. This makes it possible to recognize groups of researchers that together work for one goal. The prize, I think, is important especially because it recognizes the modern way science is done; with large international collaborations.
