  Could dark energy explain the order in universe?

+ 0 like - 2 dislike
1795 views

Is the growth of dark energy the adequate explanation of creation of astronomical objects from the perspective of the second law of thermodynamics? If dark energy is homogeneous space filling with constant density in an expanding space, it intuitively appears as the cumulative energy that permits decreasing entropy in the development from the time when neutral hydrogen first appeared.

Closed as per community consensus as the post is a popular science question.

Hi Lehs, I have some diffidulties in understanding what exactly you are asking, can you elaborate a bit on your thoughts? For example the dark energy (density) is assumed to be rather constant, and matter was probably created in the context of the reheating after the early inflation ended for example. Also, I dont understand what you mean by the perspective of the third law of thermodynamics?
I agree with Dilaton. Could you provide some further thoughts?

Ah ok, after the edit I see that you are talking about the second law of thermodynamics, which makes a lot more sense... Maybe you can correct this in the question?

Popular science questions are not appropriate for PhysicsOverflow. Voting to close. Would Quora be a better home for your question?

@dimension10, thanks for the hint, but if the question wasn't interesting for professional scientist why would I desire an answer from elsewhere? I guess that the question is inadequate somehow and impossible to answer even after the corrections. Perhaps the intuitive approach to the phenomena dark energy and cosmos isn't appropriate enough and that for the moment it is only possible to represent dark energy in a theoretical manner e.g. as a cosmological constant in field equations.
