Nou panse sa se sa a te pase, Et la raison Poukisa nou santi très fortement ke li dwe te koze yon supernova se sèl mwayen ki vrèman lou eleman yo tande sa jan yo ka fòme ou sèl fason nou konnen ke yo ka fòme nan ti jan de chalè a de yon supernova, Et Iranyòm nou, Iranyòm sa semble pou li nan sistèm solè nou sou latè a, sanble pou fòme environ lè a yo te òdone fòmasyon sou latè, nan osijè de kat pous bilyon ane de sa, e nou ap pale nan yon ti kras plis pwofondè nan pwochen vidéos sou exactement jan figi moun sa soti, men, depi Iranyòm a semble osijè de te menm laj kòm nou sistèm solè an, li dwe te fòme nan alantou an menm tan an, e li dwe te fòme pa yon supernova, e li dwe vini nan yon supernova, se konsa yon supernova shockwave dwe te pase atravè nou pati nan Linivè, e se yon rezon pou gaz pou jwenn compressés Et kòmanse pou accrete.

We think that's what's happened, and the reason why we feel pretty strongly that it must've been caused by a supernova is that the only way that the really heavy elements can form, or the only way we know that they can form is in kind of the heat of a supernova, and our uranium, the uranium that seems to be in our solar system on Earth, seems to have formed roughly at the time of the formation of Earth, at about four and a half billion years ago, and we'll talk in a little bit more depth in future videos on exactly how people figure that out, but since the uranium seems about the same age as our solar system, it must've been formed at around the same time, and it must've been formed by a supernova, and it must be coming from a supernova, so a supernova shockwave must've passed through our part of the universe, and that's a good reason for gas to get compressed and begin to accrete.
