It is an interesting topic--the curse of immortality. In fact, many times life can only be a kind of suffering, so I guess "enter that great mystery of oblivion" must be a fresh even romantic experience.

Oh, I just check "worm hole "online. It shows that its Chinese name should be called 黑洞/black hole and it seems that the worm hole can absorb the materials near to it. However, I wonder how other species can depart through the wormhole to a new dimension, whereas the "single alien" chooses to enter the wormhole and die. At the same time I want to know what Arsanthe travellers mean. Please forgive my ignorance and childish question. I am really very curious about what "Arsanthe" is.(I failed to get any answer from Google) Thank you!

P.S. : No. Worm hole is not the black hole. (I made a mistake.)
