After the Big Bang: Image shows the changing rate of expansion of the universe since the Big Bang 13.7 billion years ago. A new study may offer the first clues of what happened prior to the Big Bang.

They also explored a second energy field, called the 'curvaton', which had been previously proposed to give rise to the fluctuations observed in the CMB.
They introduced a perturbation to the curvaton field that turns out to affect only how temperature varies from point to point through space, while preserving its average value. Based on this, the researchers said, the new model predicts more cold than hot spots in the CMB.
The findings hold the key to understanding more about inflation, said Erickcek. "Inflation is a description of how the universe expanded… Its predictions have been verified, but what drove it and how long did it last? This is a way to look at what happened during inflation, which has a lot of blanks waiting to be filled in."
But the perturbation that the researchers introduced may also offer the first glimpse at what came before the Big Bang, because it could be an imprint inherited from the time before inflation. "All of that stuff is hidden by a veil, observationally," Kamionkowski added. "If our model holds up, we may have a chance to see beyond this veil."

First clue
The flaw, i think, was that all traces were obliterated before the bigbang.

assumes a few things
like an Inflaton and a Curvaton exist. Why not a varying speed-of-light cosmology that doesn't have to assume an unobserved "Inflaton" field and an equally unobserved "Curvaton"?
Something for the brains, I know you guys know the answer.
I have come across the fact that some people believe that the big bang came about by two "planets" colliding with each other. That this apparently formed Earth.
These planets where very similar but their cause in the sky meant that they were a hit and run waiting to happen.
Since I found this out, a while ago I may add, I have forgotten the name of the other planet. One of the brain boxes that come to this cool site knows the answer.
If someone anyone could please remind me what the planets name is I would be so grateful.
Thanks in advance.
