Speaking as a squirrel expert, you don't need to unify squirrels and grapefruit. Just leave the grapefruit somewhere the squirrel can find it and it will do the rest of the work for you.
Mouseover text: Our models fall apart where the three theories overlap; we're unable to predict what happens when a nanometer-sized squirrel eats a grapefruit with the mass of the sun.
To be fair, squirrel behavior and grapefruit behavior are described accurately by neither quantum mechanics nor general relativity. So this checks out.
What do you mean? Both theories can easily handle squirrels and grapefruits. General relativity can incorporate electromagnetism (Kaluza-Klein theory) and quantum mechanics can incorporate Newtonian gravity.
Was it xkcd that said something like, 'we've got pretty much all of it figured out except really big things, really small things, really hot things, really cold things, really fast things, and turbulence"? Or was that a SMBC...
Telking about the alt text:
If the mass of the sun were concentrated in a grapefruit, it would be a black hole, since the schwarzchild radius of the sun is roughly 2.9km, compared to a grapefruit's radius of 0.00015km
Apparently roughly 5.05•10-28 m, compared to 1•10-9m in a nanometer
So in short, the grapefruit would actually eat the squirrel, and then maybe the things around it, assuming it didn't die of hawking radiation too quickly
It is for a 0.300 kg squirrel, which according to Wikipedia is the upper bound for a red squirrel, however I believe the answer will be similar no matter what squirrel you take
Oh. I was hoping it was the mass of the downsized squirrel :( In that case we could maybe do something with an ultra-dense nanometer squirrel
So if we squeeze a rather large red squirrel to fit inside a cube of 1x1x1 nanometers, we're not getting a black hole. We can scrap the merging black holes scenario then.
I tried running the numbers for the estimated mass of a nanometer-sized squirrel but it didn't accomplish much, except making the sc radius even more ridiculous (somewhere in the area of 10-51m).
I feel like this missed the opportunity for the third set to be human sized objects. Then the joke could have just been about interdepartmental University politics.

Well we have a pretty good idea, given anything under around 3km with the sun's mass would become a black hole

Don't get it? explain xkcd

SMBC's book, "Science: Abridged Beyond the Point of Usefulness"
Wait which section does dropping my car off a skyscraper count as? I mean... asking for a friend
Depends on how many squirrels-per-grapefruit your car's engine can handle
2 squirrels / 0 grapefruit =

Forgetting the important question here: What would the schwarzchild radius of a nanometer-sized squirrel be?
Maybe this is a merging black holes scenario
Apparently roughly 5.05•10-28 m, compared to 1•10-9m in a nanometer
So in short, the grapefruit would actually eat the squirrel, and then maybe the things around it, assuming it didn't die of hawking radiation too quickly
Ok, so around one millionth of the upper bound of an electron's radius.
Is that for the mass of a regular-sized squirrel?
It is for a 0.300 kg squirrel, which according to Wikipedia is the upper bound for a red squirrel, however I believe the answer will be similar no matter what squirrel you take

Just not to the individual squirrel that you happen to take.
Answer will feel very different, to that particular squirrel.
