本篇是閒聊文…… 我先承認自己是看了一些YouTuber 開始胡思亂想…XD 總覺得宇宙大爆炸的動力~起始於奇異點的互撞既然霍金說宇宙大爆炸就是黑洞形成的相反那就可以再進一步的發想黑洞其實本質就是一種坍縮～縮到連原子內部的結構都縮了幾百億年後如果黑洞之間的距離又跟著坍縮造成大規模的黑洞互撞造成多個奇異點互撞那麼這些被”儲存"的能量是不是可以在一瞬間全部爆發出來? 所以宇宙的生命是不是就是這樣？又爆炸又坍縮~來回反覆 (打我啊笨蛋) 其實是看到維基上還真的有學者真的去計算裸露的奇異點長什麼樣： https://i.imgur.com/W31uY9R.jpg

以下附上原文： https://en.wikipedia.org/wiki/Naked_singularity From concepts drawn from rotating black holes, it is shown that a singularity, spinning rapidly, can become a ring-shaped object. This results in two event horizons, as well as an ergosphere, which draw closer together as the spin of the singularity increases. When the outer and inner event horizons merge, they shrink toward the rotating singularity and eventually expose it to the rest o f the universe. A singularity rotating fast enough might be created by the collapse of dust or by a supernova of a fast-spinning star. Studies of pulsars[2] and some comput er simulations (Choptuik, 1997) have been performed.[3] Mathematician Demetrios Christodoulou, a winner of the Shaw Prize, has shown t hat contrary to what had been expected, singularities which are not hidden in a black hole also occur.[4] However, he then showed that such "naked singulari ties" are unstable.[5] -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 182.235.8.52 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/sky/M.1604910666.A.DF2.html
