We understand that for the Universe to be flat, the critical mass of everything that has mass must total an omega of 1.0. At first, with our lack of knowledge regarding dark energy, we thought that the universe that we detected (ordinary matter and dark matter) did not even add up to a third of...

Thanks! I now get that globally, the universe needs not to be conserved and it makes sense that the no net energy would be an outdated or pseudoscientific idea. One question though: what does it mean that it is spatially flat?

Perhaps it began in equal amounts -eg. during the plasma phase as seen in the CRB, but that changed?

That was what my interpretation of it was after reading about it. From what we know the Universe is flat. As well, some love the idea of there being a net zero energy with the negative energy of gravity and the positive energy of acceleration cancelling each other out implies that nothing can...

Physicists have observed the cosmic radiation background to conclude that the universe is flat (or within the margin of error of being flat). This means that the Universe contains the critical density needed to keep it flat, which is a mix of ordinary matter, dark matter and dark energy (I...
