Witryna14 gru 2024 · 5. The big bang is certainly spacelike. If you use the definition in Penrose 1973, then the big bang is not a naked singularity. See pp. 85-86 of that paper. He defines a naked singularity as one that can be in both the past and future light cones of the same observer. Witryna2. As an example, look at the Penrose diagram for the Schwarzschild metric. You have a pair of null coordinates you can define if you like, along axes that lie diagonally at …

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very young and when it comes to using it to explain life, physicists struggle.

There is a single horizon at r = 0.5 r s. Finally for the naked singularity Q = 0.6, the escape velocity never reaches c so there is no horizon.
