Are you denser than a 12 billion solar mass black hole?

Actually, he is. Unlike regular black holes resulting from supernova collapse, a super-massive black hole is not very dense.
e.g. a one-billion solar-mass (2x10 to 39kg) hole would give a density of 200kg/m3 - less than that of cork!


Some have proposed that we may living inside an even bigger black hole.

where the breastfeeding percentage is nearly 100% (I assume you are talking about Africa or somewhere here)

Where did you get that Idea? 100 years ago? Africa actually has quite a low rate of breastfeeding now, with some exceptions like Malawi.
Numbers depend on the age, and whether you mean exclusive.

U-235 has a much shorter half-life, hence a much higher radioactivity.

Not really. It is still 700 million years for U235. A few times almost no radiation is still almost nothing.
A few kilos of uranium would be no worse than sleeping over a pile of bananas.

Its things like radium and plutonium, that are orders of magnitude more unstable, where you need to start considering the hazard.

From Wikipedia, the free encyclopedia
Doxing (from dox, abbreviation of documents),[1] or doxxing,[2][3] is the Internet-based practice of researching and broadcasting personally identifiable information about an individual.[3][4][5][6] The methods employed to acquire this information include searching publicly available databases and social media websites (like Facebook), hacking, and social engineering. It is closely related to cyber-vigilantism, hacktivism and cyber-bullying.

Doxing may be carried out to aid law enforcement, business analysis, extortion, coercion, harassment, public shaming and other forms of vigilante justice.[7][8]

How is this remotely of any interest to science, or the slashdot community?
Does it overturn some previous hypothesis that twin births are a recent phenomenon?

The researcher estimates the woman was in her early twenties when she went into labor. She likely didn’t know she was having twins.

No shit! Was the village ultrasound machine broken?
How does this pointless crap make it to the front page of slashdot?
