Chaobergin气体支持的虫孔的理论构造

Theoretical construction of wormholes supported by Chaplygin gas

Peter K. F. Kuhfittig

摘要:

本文从一般线元和爱因斯坦张量出发,结合物态方程,研究了广义Chaubergin气体(GCG)支持的可穿越虫洞的可能存在或构造,从而继续了作者早期关于幻影能支持的虫洞的研究.数值技术被用来证明虫洞时空的存在:(1)满足咽喉处的耀斑条件;(2)由于低潮汐力和咽喉附近的短距离,类人旅行者可以穿越;(3)渐近平坦。似乎有大量的解决方案,避免了事件视界,这表明自然发生虫洞的可能性。

英文摘要:

The purpose of this paper is to examine the possible existence or construction of traversable wormholes supported by generalized Chaplygin gas (GCG) by starting with a general line element and the Einstein tensor, together with the equation of state, thereby continuing an earlier study by the author of wormholes supported by phantom energy. Numerical techniques are used to demonstrate the existence of wormhole spacetimes that (1) meet the flare-out conditions at the throat, (2) are traversable by humanoid travelers, thanks to low tidal forces and short proper distances near the throat, and (3) are asymptotically flat. There appears to be an abundance of solutions that avoid an event horizon, suggesting the possibility of naturally occurring wormholes.
