摘要

我们证明，超大质量时空也存在于具有正宇宙常数的维度中。它们可以通过球形零尘壳的坍塌产生。壳层的外部是一个混沌时空，也就是说一个局部的德西特时空，它不能作为德西特空间的商来获得。

Ultra-massive spacetimes in 2 + 1 ...

We show that ultra-massive spacetimes exist also in dimensions with a positive cosmological constant . They can be created through the collapse of a spherical null dust shell. The exterior of the shell is then a Mess spacetime, that is to say a locally de Sitter spacetime that cannot be obtained as a quotient of de Sitter space.
