| 3. | The simplest physical model for an appropriate dark energy component is a single slowly - rolling scalar field , sometimes referred to as quintessence 解释黑暗能量最简单的物理模型,是一个单一而缓慢滚动的纯量场,有时称为真空场。 |
| 4. | Cosmologists already ascribe cosmic inflation , and perhaps the dark energy ( distinct from dark matter ) that is now causing cosmic acceleration , to scalar fields 关于宇宙暴胀,以及引发宇宙加速膨胀的暗能量(有别于暗物质) ,宇宙学者已经将之归因于纯量场。 |
