High Mass Stars: Crash Course Astronomy #31 Domi D'Orient 158 Views • 7 years ago

Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge swarm of neutrinos, blast through the star’s outer layers, causing it to explode. The resulting supernova creates even more heavy elements, scattering them through space. Also, happily, we’re in no danger from a nearby supernova.

Nier: Automata PC Walkthrough 20 - 9S Breaking Through Deen Doughouz 641 Views • 8 years ago

Nier: Automata (Japanese: ニーアオートマタ? Hepburn: Nīa Ōtomata, stylized as NieR:Automata) is an action role-playing video game developed by PlatinumGames and published by Square Enix for PlayStation 4 and Microsoft Windows. The game was released in Japan in February 2017, and worldwide the following month. Nier: Automata is a sequel to the 2010 video game Nier, a spin-off of the Drakengard series. Set in the midst of a proxy war between machines created by otherworldly invaders and the remnants of humanity, the story follows the battles of a combat android, her companion, and a fugitive prototype. Gameplay combines role-playing elements with action-based combat and mixed genre gameplay similar to that of Nier.

Nier: Automata opens with 2B and 9S opening the way for a future incursion into machine territory, working to clear out machine threats for the local Resistance. With help from Anemone and later Pascal, 2B and 9S defeat multiple machine threats. During their missions, they witness the birth of and later fight Adam and Eve, physical manifestations of the machine network who reveal that their creators were destroyed centuries ago. 2B and 9S also encounter A2, who is on the run from YoRHa. It is revealed that the machines are beginning to feel emotions and gather in groups, and some like Pascal's group have grown tired of fighting. 9S is eventually captured by Adam, who is killed by 2B. Deprived of his brother, Eve goes mad with grief and drives the machines under his command into a frenzy. 2B and 9S kill Eve, but 9S is infected with the machine's logic virus, forcing 2B to kill him. Despite his body dying, 9S's personality is saved in the local machine network, allowing his transfer into a new body. The second playthrough follows the opening narrative from the perspective of 9S, offering new insight into the machines and Adam and Eve. 9S also learns that humanity has been extinct since the events of Nier aside from a server on the moon holding humanity's DNA and history. YoRHa and its mission were created to keep the androids from losing morale. He also encounters a glitch when performing a standard server sync, and halts the procedure for both himself and 2B.
