Hello dear reader, three Japanese astronomers/astrophysicists just discovered that as "a natural consequence of the elementary processes of dust growth, [...] a new class of planets can be formed around supermassive black holes" (P)

Basically science just stated that planets, and therefore planetary systems, in theory can naturally form around black holes

But this dumb blog has a different story to tell 'bout this...

Planetary system formation around a black hole according to @sciencemug
That's how a planetary system really comes to exist around a black hole according to @sciencemug

A "Type III Civilization" is the most advanced type of civilization according to the I to III Kardashev scale.
Nikolai Kardashev was a Russian astrophysicist (1932-2019) author of the paper "Transmission of Information by Extraterrestrial Civilizations" (1) published on Soviet Astronomy AJ in 1964. In the paper Mr. K writes about the "distinguishing properties of artificial sources of cosmic radio-frequency emission" (1): basically the guy describes what are the characteristics needed, in terms of energy availability and type of transmissions, for successful communications to happen between galaxies (and their civilizations).
In his paper Mr. K comes up with a classification of civilizations that goes like this:
- Type I civilization has "a technological level close to the level presently attained on the Earth" (1).
- Type II civilization is "capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a "Dyson sphere" * (2)) (1).
- Type III civilization is "in possession of energy on the scale of its own galaxy" (1) (but apparently it's not in possession of a decent swing, hence, it sucks at cosmic golf...).

* Dude, if you don't know what a Dyson sphere be, well, you definitely don't like Star Trek or sci-fi in general... Anyway, Freeman J Dyson (born in 1923) is a British-American physicist who, in a paper published in 1960 on Science, writes that if "extraterrestrial intelligent beings exist and have reached a high level of technical development, one by-product of their energy metabolism is likely to be the large-scale conversion of starlight into far-infrared radiation" (2) and that it is reasonable to suppose that "within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star" (2). Finally dude Dyson concludes that the "most likely habitat for such beings would be a dark object, having a size comparable with the Earth's orbit, and a surface temperature of 200 deg. to 300 deg. Kelvin [(T-Kelvin=T-Celsius + 273.15... Oooh for The Mighty SI System Sake! Ok, ok, T-Kelvin=(T-Fahrenheit + 459,67) / 1,8 )]. Such a dark object would be radiating as copiously as the star which is hidden inside it, but the radiation would be in the far infrared, around 10 microns wavelength."(2).
There you go pal, that's the Dyson sphere.

Soooo, dear reader, apparently a team of scientists used epigenetics to find out a scientific way to calculate the actual human equivalent of dogs age (P). The formula the brains came up with is "human-age=16ln(dog's-age)+31". That is if a dog, for instance, is 3 years old, then its human equivalent age is 16xln3+31, meaning 16x1.01+31, meaning about 47.

What was the true goal of this research, are you asking yourself, dear reader? Well, the following cartoon is the answer this dumb blog has for you, pal...

Oooh hallo dear English speaking-reading-hearing visitor, welcome back to me, @sciencemug, the blog/podcast/twitter&instagram accounts/entity behind the unsuccessful e-shop stuffngo on which tells you great science stories looks deep into your soul aaaand in doing so finds that gym locker key you lost in 2005 along with a couple of stale candy and a used bus ticket, aaand which talks to you thanks to the voice, kidnapped via a voodoo-wireless trick, from a veeery very very dumb human. Aaaaand which does all of this in Eng?ish, a language that is to proper English what the names of Icelandic volcanoes are to shortness.

Today I'm gonna launch a new space of this blog-podcast called “Weird patent series”, a space, as the name suggests, dedicated to the most absurd things you humans have patented, invented, thought.

In a recent interview to a researcher, PiPs, probably - but given what it is not necessarily - joking, mentioned the necessity for the invention of a diaper for birds (well, to be precise for flying animals in general, see the post if you wanna know the origin of that). 

Pffff, a diaper for birds, nonsense, dear reader, right?

Weeeell, dear reader, apparently that idea has indeed been already deeply worked out, and even covered by (at least as far as I know now) not one, but two patents!

Now of course you, dear reader, are super willing to know all 'bout these inventions, right? Aaaaand of course here I am to provide you these fundamental piece of information.

Let's go then!

Sooo dear reader, scientists have found out that, at the moment, the universe is getting bigger and bigger waaay faster than predicted.
It may depend on some new kind of dark energy, or on some new unknown particle, ooor on some new physics in need to be discovered altogether.

Those are all good hypothesis, indeed.

But this dumb blog has a different one...
