虫洞、空泡与真空能量压制

Wormholes, Void Bubbles and Vacuum Energy Suppression

Enrico Rodrigo

摘要:

观测到的宇宙学常数值与从已知物质场的零点能量所预期的值之间的巨大差异,可以通过假设在宏观尺度上,任何体积的时空的绝大多数都是字面上的虚无来消除。这种虚无或空隙是由微小空隙气泡的增殖成核(也称为“空泡”)造成的。“空泡”或“半虫洞”),膨胀直到它们的表面,假定是2-膜,碰撞。这个过程导致了各种大小的空气泡的密集堆积,只留下气泡之间消失的间隙区域供时空占据。在任何表观体积内包含的实际空间量的这种巨大减少相应地减少了有效零点能量密度。与以前基于虫洞的真空能量抑制尝试不同,目前的方法完全是洛伦兹的,并导致宇宙学常数的非零值。

英文摘要:

The gargantuan discrepancy between the value of the observed cosmological constant and that expected from the zero-point energy of known matter fields can be eliminated by supposing that on macroscopic scales the overwhelming majority of any volume of spacetime is literal nothingness. This nothingness or void results from the proliferative nucleation of tiny void bubbles (a.k.a. "bubbles of nothing" or "semi wormholes") that expand until their surfaces, presumed to be 2-branes, collide. This process results in a dense packing of void bubbles of various sizes that leaves only the vanishing interstitial regions between bubbles for spacetime to occupy. This vast reduction in the amount of actual space contained within any apparent volume, reduces correspondingly the effective zero-point energy density. Unlike previous wormhole-based attempts at vacuum energy suppression, the current approach is entirely Lorentzian and results in a nonzero value for the cosmological constant.
