english: And each cloud is compacted, gravity gets more powerful as density increases, the temperature begins to rise at the center of each cloud, and then, at the center, the temperature crosses the threshold temperature of 10 million degrees, protons start to fuse, there's a huge release of energy, and -- bam!
non_english: Vsak oblak se zgošča, gravitacija postane močnejša in ko gostota narašča, narašča temperatura v središču vsakega oblaka in potem, v središču, temperatura preseže toplotni prag 10 milijonov stopinj, protoni se začnejo zlivati, sprošča se ogromno energije in – bum!
