如果密度正好等于临界密度，宇宙则是平坦的，但很可能仍然是无限的。

If the density just equals the critical density, the universe is flat, but still presumably infinite.

虽然还没有确定这些质量是否足以使宇宙停止扩大，一些物理学家认为这些推测正趋向接近临界值，这是意义重大的。

While it has not yet been determined whether this mass is sufficient to close the universe, some physicists consider it significant that estimates are converging on the critical value.

此外，存在的实体维度显然可以挺过一切生物临界点，因为我们的身体的物质组成部分，会以不同的方式和宇宙融混在一起。

Moreover, the physical dimension of existence clearly persists beyond any biological threshold, as the material components of our bodies mix and mingle in different ways with the cosmos.
