引力子-引力子相互作用对暗物质的意义

Implications of Graviton-Graviton Interaction to Dark Matter

A. Deur

摘要:

我们目前对宇宙的理解需要暗物质和暗能量的存在。我们在这里描述了一种自然机制,它可以使外来的暗物质和可能的暗能量变得不必要。引力子-引力子相互作用增加了物质的引力结合。对于像星系这样的大质量系统来说,这种增加可能大到足以使外来的暗物质变得多余。在弱场近似下,我们计算了对星系旋转曲线的影响,并找到了正确的大小和分布,而不需要任何参数或额外的外来粒子。塔利-费雪关系也自然地从这个框架中出现。计算结果进一步应用于星系团。

英文摘要:

Our present understanding of the universe requires the existence of dark matter and dark energy. We describe here a natural mechanism that could make exotic dark matter and possibly dark energy unnecessary. Graviton-graviton interactions increase the gravitational binding of matter. This increase, for large massive systems such as galaxies, may be large enough to make exotic dark matter superfluous. Within a weak field approximation we compute the effect on the rotation curves of galaxies and find the correct magnitude and distribution without need for arbitrary parameters or additional exotic particles. The Tully-Fisher relation also emerges naturally from this framework. The computations are further applied to galaxy clusters.
