The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full, it follows the rules for capitalisation of a common noun; i.e., joule becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.

309. If GW190521 is a boson star merging, the present one remains the largest. See note [246][247]
310. It is important to specify that the energetic reduction for beaming (invoked to explain so much energetics and jet breaks) is expected in the "Fireball model", which is the traditional one; other main models explain both Long and Short GRBs with binary systems, such as "Induced Gravitational Collapse", "Binary-Driven Hypernovae" which refer to the "Fireshell" one, in which cases the beaming isn't assumpted and the isotropic energy is a real value of energy due to the rotational energy of the stellar black hole and vacuum polarization in an electromagnetic field, which are able to explain energetics up and over 10⁴⁷ J

314. Assuming the uncertainties about the masses of the objects, the values of the LIGO Data are taken in consideration; so we have a newborn black hole with about 142 solar masses and the conversion in gravitational waves of about 7 solar masses

317. A research claims that this is instead a boson stars merging with approximately 8 times more probability than the black hole case; if so, the existence and the collision of boson stars there would be confirmed together. Furthermore, the energy released and the distance would be reduced. See the following note for the link of the research
