A Hero's First Step (MHA)

Reader mode
I'm glad that the gravity + Light combo won. Yeah the Gravity and Magnetic combo seemed more powerful but Izuku is already powerful enough as is. Rather we try to the more interesting choices and combos than pure power gaming/min maxing.

Reminds me of these articles where they all go on about how physics proved the universe is "not real".

of course the title doesn't mention which definition of "real" they're using, because why would you click on it otherwise?

Also if the light absorbing properties manifested in Izuku, i would assume that light producing effects would also, making him incredibly bring object instead of a black cutout.
Though it might be something we learn to do with practice, and we did start with a boost in light so might not be too far from us even if we do not start with it.

It would depend on his body temperature. The light production of a black body is a function of its temperature.

And actually black body definition is very much in line with common sense definition. A black body at room temperature would, in fact, be very, very black.

And i am not aware of any black bodies that exist at room temperature.
Which is why the way physics uses the term is not in line of anyone else.
Because you ask what is the blackest/darkest object in the solar system, they are not going to be thinking of the sun because the answer is largely semantic outside very specific context.
When almost anyone not a physician (and even most physicians most ofd the time) talk about how bright something is, they are not talking of how much light they reflect, but how, well, bright it is to look at.

And i doubt Izuku's body temperature is likely to be relevant to how much light he radiates because while he is a sun, he is so in a much more conceptual sense rather than physics sense.

Yeah, but Izuku definitely runs hotter than your average human now that there's a stellar reactor in his chest. Probably not 'blood is near boiling' levels, but still warmer than would normally be healthy.
 
I do agree that it seems like people are over thinking things when it comes to quirks. What with how quirks tend to ignore normal physics a lot of the time. I think people need to remember that a lot of fictional writers not only aren't actually knowledgeable about advanced physics but don't really care enough to consider them much when writing fictional settings.
 
Anyone got ideas for a Hero name? Depending on how we want our brand to be, it could go from a child friendly "the Sunny Hero, Midday". to epic "Unconquered Hero, Solaris".

Maybe Green Sun Prince?
 
The Unconquered Sun, Helios.
Yes, i am blatantly stealing from Exalted.

You are, actually. Take a large cavity with rough unpolished walls (for example a can of soda). Poke a small hole in it (the smaller, the better). The insides are now a black body.

But yeah, I am overthinking it.

In that there is very little light for it to reflect.
Not in that it just does not reflect light.
That is not a property of the object itself, only the context it exists in.
Might as well call a rack inside a deep care a black body.

I've actually watched a video on youtube yesterday when they said THAT's how they tried to verify the theories on how black bodies would behave (and that, ironically, that's where the first formulations of quantum mechanics came from, if indirectly)

No, it genuinely wouldn't reflect light. Here. The physics works like this: light enters the hole. Part gets absorbed, and part gets reflected. Because the whole is small and reflection is diffuse, almost all light doesn't go back in the hole. It gets shined onto different parts of the cavity. Where some more light will be absorbed, and some more reflected. If you have a large enough cavity, then the amount of times light gets in contact with a wall before exiting will be large. Let's say that a ray of light impacts a wall 100 times before exiting the cavity. Let's say that the reflection coefficient of the inner walls of the cavity are 0.9. (0.9)^100=0.000026, which is the effective reflection coefficient of the cavity as a whole. It's a black body, even if the walls are nearly perfect reflectors.

Please note how the body does actually reflect the light.
Yes, the light can't escape the enclosure, and will eventually stop, which will also hapen if you make a completely enclosed room covered in mirrors, turn on a flash light and then turn it off, eventually light runs out (because nothing we know of reflects 100% of the light, some is always absorbed).
What you have is a thing that, in some ways, behaves like a black body and can be used to test some ideas about them.
But i would not call it a black body the same way i would call a sun a black body (though i generally would not call sun a black body because, it is a very bright object people should not look at), though i guess physicians would call it a black body, so technically you are correct.
Other similar black bodies are things painted with extremely black paint, i am certain they have many interesting application in physics, but almost all of them are going to be way past my educational level.

It is a bit surreal to have a PC that isn't some variety of social expert.

Will be fun to develop that thread, wherever it goes~

If luck is on our side, we'll be able to cultivate least one good friendship before we head off to UA.

We need to hit 12 in every stat within the next 11 months, so we can't stay bad at it forever. In fact, along with Martial, we need to make Diplomacy a priority to raise. Of course, a 12 is only above average by High School standards.

We don't actually. Granted it'd probably be a good idea to improve but there is no strict need for Izuku to reach 12 in everything.

Ah! Missed that. We should definitely still improve Diplomacy, IMO, but fair enough.

8 is average highschooler.

That's...exactly what I said? I said a 12 is above average for a High Schooler but not above average in general.

The Upside Hero Sunnyside is genuinely witty, I'd never have thought of it, kudos to you.
 
Nightlight is a great contrast to Izuku's origin story, for lack of better term. I like it.
