Today, the universe as we see it is expanding, rarifying (getting less dense), and cooling. Although it’s tempting sicuro simply extrapolate forward mediante time, when things will be even larger, less dense, and cooler, the laws of physics allow us onesto datingranking.net/it/menchats-review/ extrapolate backward just as easily.
