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...

Sounds like PMH, if they exist, are essentially the Universe’s ultimate cannonball.

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..

If I remember correctly, Stephen Hawking had to do some serious math in the 1970s to convince himself a tiny black hole was not hiding in our Sun

I think there's a PBS Space Time on it (of course)

adding: yup! love that show

And yet no one does a thing about it.

This is one of those headlines where I simultaneously think "cool" and now have a new source of low-grade background anxiety about. It can have a seat next to false vacuum collapse.

Fuck this site with its multiple ads opening up and auto playing videos.
