Fermilab Reports Dark Energy Not Needed
An anonymous reader writes "A Fermilab press release
reports that the expansion of the universe may be
explainable without the need for dark energy or a
cosmological constant. Apparently, ripples from
inflation in the early universe may account for
the observed expansion rate of the universe."
Mod parent insightful. We know very little about the early universe, but we sure have a lot of research articles that are being continually published and refuted.
The limmit is probably caused by the speed of light, We can only "see" something if the energy it irradiates arrive at Earth.
So, if a new star is born now at 5 light years from here, we'll see it only 5 years later when its light hit Earth.
Then, if the universe is T years old, and is expanding at the speed of light, we could only see what is T light years from here.
Of course its just an opinion, since i really suck at phisics.
