What do you know today that you didn't know yesterday?

I'm a mouthy little bitch. Well, okay, maybe I did know that, but I at least thought I knew when to shut up.

Apparently, it’s possible to have a story where a social media influencer is goaded into a live-streamed suicide by her fans, and somehow not have that be the fucked up part.

It is said a supernova can be brighter than an entire galaxy, and is thus the brightest common object in the known universe.

However, it is expected that in the near future, technology would be available to construct a laser which would actually be brighter than a supernova, in the sense it would put out more power in xray than a supernova puts out across all electromagnetic spectrum,  but only for something like one quintillionth (million trillion) of a second.  Of course the total energy the laser can emit is still infinitesimally small next to what the entire supernova event emits over its life.    

But for one million-trillionth of a second, the wits and craft of man can literally outshine anything else in all of the entire known universe.

That’s still something.

I’m not sure massive output in x-ray wavelengths would qualify as ‘brightness’.

The Vikings have a bye in week two this year. Guess I'll have to look for some other distraction besides the heavy drinking.

So-called free dating web sites are only free for certain large values of free.

in astronomy any electromagnetic energy emitted counts as brightness.

That doesn’t appear to be the case.

No, it is actually the case.

It is typical, for example, to talk about the brightness of a radio emission or an x-ray emission.

Brightess is usually considered to be equivalent to luminosity.

It isn’t. Brightness is (unsurprisingly) how bright an object appears to an observer. Luminosity refers to total EMR emissions.

To speak of the ‘brightness’ of a radio or x-ray emission may be typical, but it isn’t correct.
