What are your thoughts on dark matter and dark energy?

all energy is pure, it is how you direct that energy that can make it dark

Um, I'm talking about physics.

It's always good to add another angle, dark energy does not imply physics to me, sorry. I only use light energy.

Dark matter - conjecture on dark matter is based on calculations using our current knowledge of physics. Is it there or not? If yes, then maybe some or all of our knowledge and assumptions are correct, if no then maybe Einstien was wrong? As far as energy is concerned, things do run down and entropy increases. There could come a time when all the energy in the known universe could run down and the temperature would be absolute zero, no more stars would be formed, all matter, physics, chemistry, laws of nature as we know them would be diferent.

i think dark matter is in space far away from earth7our slar system. and now about energy its the energy possessed by this dark matter... dark matter is named as black holes

I dont know what exactly dark matter is .. all i know is that it accounts for the excess gravitational pull that is observed in our galaxies

Interesting subject. I really have no thoughts on dark energy or dark matter. But am interested, what are your thoughts? then perhaps we can start a debate?

In astrophysics, dark matter is matter that does not emit or reflect enough electromagnetic radiation (such as light, X-rays and so on) to be detected directly, but whose presence may be inferred from its gravitational effects on visible matter. Among the observed phenomena consistent with the existence of dark matter are the rotational speeds of galaxies and orbital velocities of galaxies in clusters, gravitational lensing of background objects by galaxy clusters such as the Bullet cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies. Dark matter also plays a central role in structure formation and Big Bang nucleosynthesis, and has measurable effects on the anisotropy of the cosmic microwave background. All these lines of evidence suggest that galaxies, clusters of galaxies, and the universe as a whole contain far more matter than is directly observable, indicating that the remainder is dark. http://en.wikipedia.org/wiki/Dark_matter
