Primordial Black Holes May Be Secretly Exploding White Dwarfs Across the Milky Way
Tiny Black Holes May Be Exploding Stars Across the Milky Way

New research suggests that primordial black holes—hypothetical remnants from the early universe—could trigger white dwarf stars to explode as Type Ia supernovae. By comparing models with real supernova remnants and the chemical makeup of Milky Way stars, scientists found that these explosions may explain observed abundance patterns, indicating that these elusive black holes might have shaped our galaxy's chemical evolution.
Our work suggests that some supernova that we observe in the sky could be a result of the PBHs. Therefore, even though we cannot directly observe these evasive entities, they leave many interesting clues in nature for us to probe their properties.

Could this kind of trigger effect the standard candle application of Type 1a's? For example, if a black hole triggers a type 1a and that perturbs the type 1a light curve in some way (possibly because less mass could be consumed in the explosion than you would get if one was triggered by mass accretion) and the rate of triggering of this kind changed over time as the universe aged and somehow the population of primordial black holes changed, or the distributions of white dwarf candidates and pbhs changed...

Anyone have guesses about how a transiting primordial black hole would effect a Sun like star? Paper is about tidal forces inducing supernova in white dwarfs. For that matter how might it effect sea tides?

Kind of chilling to think about these tiny black holes. If they have enough gravitational pull to destabilize a white dwarf, I don't want to know what they'd do to our solar system.

Wouldn't Type Ia supernovas caused by blackholes have a different brightness?
That could mean the entire cosmic ladder needs to be revised, maybe this could resolve the crisis in cosmology..
