Big Bang Abandoned in New Model of the Universe

This is one of the most exciting theories I have heard in a long time. I am going to tell you why and you are going to think I am even nuttier than you already do. But, as you know, I don’t care. One night after watching some documentary about Stephen Hawking and the black hole wars, I was lying in bed just contemplating the Universe. Suddenly and image came into focus and a said aloud to my husband.

“I get it. It has a hole but it has no hole.”

Of course he groggily responded.

“What the hell are you talking about?”

I went on to explain that I had seen an image of the Universe. That it was kind of like a doughnut. But, because we are inside the ring so we just keep going around and around. From our perspective it doesn’t have a hole. And the image I saw it was all stretched out so the “doughnut hole” was almost invisible.

“A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.

Shu’s idea is that time and space are not independent entities but can be converted back and forth between each other. In his formulation of the geometry of spacetime, the speed of light is simply the conversion factor between the two. Similarly, mass and length are interchangeable in a relationship in which the conversion factor depends on both the gravitational constant G and the speed of light, neither of which need be constant.

So as the Universe expands, mass and time are converted to length and space and vice versa as it contracts.

This universe has no beginning or end, just alternating periods of expansion and contraction. In fact, Shu shows that singularities cannot exist in this cosmos.” Read the full article…
