Black holes can lose mass and energy over time. They release Hawking radiation. The smaller they are, the more radiation they emit, so the hotter they get. The end scenario is the black holes exploding into nothing. Could we observe such an exploding black hole? Maybe, if a bunch of conditions are met. If they are, we could see them with current instruments within a decade. The rest of this article is behind a paywall. Please sign in or subscribe to access the full content.

First of all, you need a primordial black hole (PBH). These are black holes that formed in the immediate aftermath of the Big Bang. Several hypotheses have proposed their existence, but we have no certainty that they indeed exist. If they do exist, they are the most likely to explode. They are not that big, and they
