Putting Black Holes Inside Stuff | Dead Planets Society Podcast

Primordial black holes are tiny versions of the big beasts you typically think of. They’re so small, they could easily fit inside stuff, like a planet, or a star… or a person. So, needless to say, this has piqued the curiosity of our Dead Planeteers.
Leah and Chelsea want to know, can you put primordial black holes inside things and what happens if you do?
Black hole astronomer Allison Kirkpatrick at the University of Kansas is back to help them figure this one out. And it turns out, despite being very small, these black holes are incredibly heavy, so ingesting and/or hugging them seems firmly off the cards - much to Chelsea’s displeasure.
Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos - from punching a hole in a planet to unifying the asteroid belt - and subjects them to the laws of physics to see how they fare.
Your hosts are Leah Crane and Chelsea Whyte.
If you have a cosmic object you’d like to figure out how to destroy, email the team at deadplanets@newscientist.com. It may just feature in a later episode.

The fundamental phenomenon of dilation perfectly explains galaxy rotation curves/dark matter. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has recently been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter. In other words they have normal rotation rates. All binary stars have normal rotation rates for the same reason.

Weight management should be a higher priority than imaginary phenomena like the "black holes", a mathematical artifact of a baseless philosophical interpretation of relativity.

@@ivant.1015 Why would they, I'm concerned for the well-being of the scientific community.
