Can someone help me fix the Wikipedia page on the black hole information paradox (https://en.wikipedia.org/wiki/Black_hole_information_paradox)? It says

> the black hole radiates mass at a rate given by dM/dt = -aT⁴ where a is constant related to fundamental constants, including the Stefan–Boltzmann constant and certain properties of the black hole spacetime called its greybody factors.

The next paragraph says that M is inversely proportional to T and that the black hole evaporates in time proportional to M³. But this isn't consistent because solving dM/dt = -a/M⁴ gives an evaporation time proportional to M⁵.

I think it's the first formula that's wrong and it should be dM/dt = -aT². But I don't know quite enough to feel confident making an edit. Is there someone out there who knows what the fix should be?

IVE -- BLACKHOLE -- FAN CONCERT 260321
https://youtu.be/IlbD6zCGyhA?si=mSd-Y_Z-iDqIEYsE

Watching this stage made me think more largely about both "Blackhole" .

Let me begin by saying how much I like the song. Like many others, I'm taken by its epic sound, and the time signature switching engages my interest, as does the use of momentary silence. Without a doubt, this is the title track of theirs I like the best since "I AM".

On the other hand, this stage confirms in my mind a comment I made about the original release: the epic sound needs an epic stage, which most music shows and concerts cannot offer. The fan concert in this video cannot provide the sets this song demands. My hope is that IVE perform "Blackhole" at one of the end of the year shows with some over the top staging of a suitably magnificent scale and style.

In the post I made about the original MV, I noted that I did not like all of the outfits. I don't think these outfits are quite right either; the naval uniform was appropriate for the performance of "Genie" that they gave earlier in the show, but doesn't complement "Blackhole" in the same way.

I'll finish on a more positive note. IVE swapped the court shoes -- pumps, in American English -- they wore when performing "Genie" for the boots we see in the linked video. I gladly note that both the boots and the court shoes have heels.
Although I think idols can look so very elegant dancing in heels, I am not a fetishist; in fact, I'm happy to see not just stiletto boots but ballet flats too, Mary Janes or jazz shoes -- anything , in fact, that will give us a break from the ugly overgrown foot look that comes with so many wedges, platforms, and stomper boots. So I'll take this stage as a footwear win if nothing else!

This is why I love physics-reality keeps finding ways to be stranger than anything we'd think to invent.

Then it would seem (to novice me) that the collapse of a gigantic star tossing off unusual elements found in globular clusters would form the black hole in the center of larger galaxies which dwarf galaxies travel with. The spin of the gigantic star would seed the spin of the black hole and its emergent galaxy.
