关于弱费米佯谬的解决

On the resolution of a weak Fermi paradox

Zaza Osmanov

摘要:

在本文中,我们认为费米悖论(FP),并提出了一个可能的解决方案,在超先进的外星文明的背景下。在这个意义上,它可以被看作是弱费米悖论(WFP)。通过假设超先进的外星人(ET)存在,并能够在脉冲星或主序星(MSS)周围构建一个巨大的环状巨型结构来消耗其发射的能量,我们考虑了环的稳定性问题,研究了平面外动力学。已经表明,对于正常的恒星,振荡时标,因此光谱变化的时标是几天的数量级,而对于MSS,它可以从几分钟到几百年不等。我们已经表明,通过高分辨率和灵敏度,欧洲南方天文台的甚大望远镜可以检测到冷($T=300$ K)或热($T=4000$ K)megastructures在整个星系,即使是非常小的振荡幅度的环。如图所示,观察到的变异性可以具有与其他一些变量相似的特征,这些特征可以被视为WFP的分辨率之一。

英文摘要:

In this paper we consider the Fermi's paradox (FP) and propose a possible resolution in the context of super-advanced alien civilizations. In this sense it can be regarded as to be the weak Fermi paradox (WFP). By assuming that superadvanced extraterrestrials (ET) exist and are capable of constructing a huge ring-like megastructure around a pulsar or a main sequence star (MSS) to consume its emitted energy, we consider the stability problem of the ring, studying the out of plane dynamics. It has been shown that for normal pulsars the oscillation timescale, thus the timescale of the spectral variability is of the order of several days, whereas for MSS it can vary from minutes up to hundreds of years. We have shown that by means of the high resolving power and sensitivity, the European Southern Observatory's Very Large Telescope can detect either cold ($T=300$ K) or hot ($T=4000$ K) megastructures throughout the whole galaxy even for very small oscillation amplitudes of rings. As it is shown the observed variability can have characteristics similar to those of some other variables, which can be considered as one of the resolutions of the WFP.
