  6. When the field is slowly - varying, the scalar field potential acts like a cosmological constant. in addition to the quintessence models, many other theories for dark energy have been proposed, including models based on super - symmetric gauge theories, super - gravity, small extra dimensions, large extra dimensions, quantum field theory effects in curved space - time. all these models are essentially based on the existence of a mass less scalar field acting at a cosmic scale

    除了真空場模型外，科學家亦提出其他解釋黑暗能量的理論，這些模型建基於不同的物理理論或假設，例如超對稱規范理論超重力增加一些小或大的空間維數量子力學在彎曲時空的影響等等，這些理論模型，返本溯源，其實背後都假設存在著一個特性類似於宇宙常數的無質量純量場。

    我們當然不甘於單單把黑暗能量等同於宇宙常數，對科學家來說，更重要的是要對黑暗能量的來源找一個合理的物理解釋。
  9. Cosmologists already ascribe cosmic inflation, and perhaps the dark energy ( distinct from dark matter ) that is now causing cosmic acceleration, to scalar fields

    關于宇宙暴脹，以及引發宇宙加速膨脹的暗能量（有別于暗物質） ，宇宙學者已經將之歸因於純量場。
  10. A first, and perhaps the most convincing candidate for the dark energy, is the cosmological constant, introduced by einstein in 1917 and later rejected by him

    黑暗能量其實很可能就是愛恩斯坦在1917年在引力方程中加入，但終被拋棄的宇宙常數。
  11. The leading candidate to explain dark energy ' s effects is vacuum energy, which is mathematically equivalent to the cosmological constant that einstein invented in 1917

    要解釋暗能量效應的首選，便是真空能量，它與愛因斯坦在1917年所創的宇宙常數，在數學上是等價的。
  12. The cosmological constant is a mathematical representation of the energy of empty space, also known as " dark energy ", which exerts a kind of anti - gravity force pushing galaxies apart at an accelerating rate

    宇宙常數是空虛空間能量的數學描述，一般稱為黑暗能量，這種反引力促使星系彼此加速遠離。
  13. In this short period of time, our understanding of the universe has been changed totally, from the vision of only 5 planets to a picture with dark energy dominated accelerating universe

    在這短短四百年時間，人類對宇宙的認知由遠古以來肉眼僅見的日月五星概念發展到今時今日的暗能量充斥、宇宙加速膨模型。
  14. The simplest physical model for an appropriate dark energy component is a single slowly - rolling scalar field, sometimes referred to as quintessence

    解釋黑暗能量最簡單的物理模型，是一個單一而緩慢滾動的純量場，有時稱為真空場。
