if either dark energy or dark matter really exist, or whether there are some errors, however minute, in the calculations that suggest these anomalies are needed.
Somehow neither fit the physics or chemistry that I learned about.

Even the experts don't know what it truly is or rather its something that must exist in some way. Wow, the big brains can't point their finger at it but explain as best they can what it must be doing. It's like going to accident and constructing the sequences that lead up to it.

In math one of the biggest events is the introduction of the number "0". Without zero that becomes a place holder and obvious great value to numbers is that is means something, even though it's a zero. Maybe, in my way of thinking, dark energy is the ideal and perfect form of matter that is nothing. Being nothing, anything it comes across allows it free access and can't slow it down. IT DOESN'T CREATE ENERGY NOR WASTE IT, but allows anything that exists once it passes its barrier to impart what matter is as if a waste product. Matter thus acts as if it was the 1st presence but isn't as "nothing" was there 1st. Nothing as in nothing. Is it such a new force that it is something from nothing. The best way to describe this is one looking into a void(cliff hanging) and steps into it. Knowing nothing of what would happen beforehand and all becomes immediately come into play, the forces that exist become all too apparent. The apparent ease of passing into nothing is better than the forces that it leads behind those forces act in greater harmony and somehow effect the outcome, which under matter acts upon matter as in gravity, is at least slows down. When not present the dark energy forces being the closet allow its existence to be known as matter passes, to include all energies or substances. What do you think buck-o's -----Willy
