>we can't detect it

It can and is being detected, mainly by gravitational lensing astronomy. It is normal baryonic matter and the more you look for it the more you find. It has been called 'dark' because it gives off very little light since the average temperature is about 3K, the "temperature of space" calculated by Arthur Eddington in 1926.

According to an 'external' source there never was a singular big bang event but there rather is a permanent cycle of such bangs, and what we observe as expansion is in reality a 4D rotation (of sorts) viewed from our 3D 'flatland' perspective. The fourth spatial dimension we're not yet aware of is then (by our convention) experienced as (more or less) linear time. A 4D being experiences physicality as well as time as cyclic, variable and selective, eternally in transformation. No beginning, no end.

Q: Was there a big bang?
A: There are many of them!
Q:How many?
A: Got a few years to take down the number?

Q: Where does background cosmic radiation come from. Does it come from one of the big bangs or many of the big bangs or some completely different source?
A:Dark matter.
Q: .. well, someone on the physics newsgroups was discussing this, so maybe it is a confirmation.

"Space and time are modes in which we think, not conditions in which we exist."

Map of dark matter (light blue), digitally superposed on a photograph made by the Hubble Space Telescope, shows that a giant ring of invisible mass surrounds the dense core of a giant cluster of galaxies called ZwC10024+1652, about 5 billion light-years from Earth. Astronomers mapped the distribution of mass in the galaxy cluster by observing the effects of gravitational lensing on background galaxies.

>hypothesis of the primeval atom

It was originally invented by theologist Robert Grosseteste (1168..1253), first head of the university of Oxford. He had the vision that his god created a tiny spot of light that expanded rapidly taking the (simultaneously created) matter with it to form a spherical cosmos.

"I was there when Abbé Georges Lemaître first proposed this theory. Lemaître was, at the time, both a member of the Catholic hierarchy and an accomplished scientist. He said in private that this theory was a way to reconcile science with St. Thomas Aquinas' theological dictum of creatio ex nihilo or creation out of nothing.

"There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

"We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture." - Hannes Alfvén

Since matter is created out of energy, would it be possible to create new molecule out of let's say oxygen, if we had enough energy to reshape oxygen molecules into something else?
