Initially I was going to incorporating this into a long rant about how the black hole in DBS isn't equivalent to a real black hole so scaling the properties of real black holes onto it isn't good scaling. And also how to properly use something like the DBS black hole.

But it seems I was beaten to the punch.

Don't take this too seriously.

Here it the feat (~7 seconds in).

Notice how initially the heart was relatively small then after A18's attack went into it, it expanded considerably.

If we accept that the black hole in DBS can scale off the all the properties of real black holes (which it can't). Then we can say black holes expand when they absorb mass in a easily quantifiable manner.

We can use E = mc² and a black hole calculator to get kind of an idea how much mass-energy the blast had.

Here is a handy dandy black hole calculator for all your black hole calculating needs.

For ease of use I am going to assume the DBS hole is a sphere.

It starts with a radius of around 1-1.5 meters and about doubles in size to 2-3 meters (source: eyeballing, I am not trying to be super precise).

Plug that into the black hole calculator and we get,

Change in mass (1.5m to 3m) =~ 1e27 kg

Use E = mc² to get the energy equivalent and we get ~9e43 joules

How much energy is this?

Well it exceeds the gravitational binding energy of Sol by almost three orders of magnitude.

It is 1e43 joules away from being 1 Foe which is the unit of energy normally used to measure supernovae.

Would it be enough energy to "destroy" a solar system? If everything was lined up nicely, definitely.

If everything was spaced out like normal... I would need to calc it out to figure that out.

I have a feeling particular interpretation of the feat might crop up elsewhere given time so y'all might as well see it here first.

NOTE: This calc was intentionally somewhat lacking in precision. There are also a number of other problems with the calc's consistency among other problems. DO NOT FUCKING USE IT IN A DEBATE.
