The good news about black holes is that even if one transited the solar system, it would be extremely unlikely to come anywhere near earth.

#5Anyone 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?

Take comfort in the fact that compared to the size of the universe, the speed of light is like molasses in January. Cosmological eschatology is a very slow game, and the odds of you being alive and in the right place to be a spectator are literally astronomically small.

#7Wouldn'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..

#8Could 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...

#9The "Great Filter" answer to the Fermi Paradox.
It seems like it would be the most efficient implementation of the Great Filter, since it would just look like a natural occurrence to any observers.
